Question(s): What are the prognostic reasoning practices of physiotherapists towards musculoskeletal disorders? Design: Exploratory phenomenological study. Participants: 15 physiotherapists who currently treat musculoskeletal disorders. Date analysis: Semi-structured interviews were implemented to collect data which was analysed using an inductive coding and thematic analysis approach. Results: Three themes were identified. First, how physiotherapists considered prognosis within clinical practice. Whilst prognosis is an important consideration, in some circumstances it either may not be considered or is implied. Second, how physiotherapists determine prognosis for musculoskeletal disorders. Several factors shaped the ability of physiotherapists to determine prognosis including how they determine prognosis, and the barriers and facilitators towards determining prognosis. Finally, how physiotherapists discuss prognosis with individuals who have a musculoskeletal disorder. These discussions were shaped by the prognostic information provided, as well as the barriers and facilitators towards discussing prognosis. Conclusion: The prognostic reasoning of physiotherapists appears to be influenced initially by whether they consider it or not. It is then shaped by both barriers and facilitators towards determining and discussing prognosis. Facilitators for this prognostic reasoning process appear to be aligned with the biomedical model of health, whilst barriers more aligned with psychosocial factors. To improve prognostic reasoning, physiotherapists should continue to strive to conceptualize prognosis within a biopsychosocial framework. Doing so will improve the ability of physiotherapists to prognosticate, which will subsequently improve outcomes associated with musculoskeletal disorders.

Background: The primary management strategy for gait impairment is the adoption of a walking aid. However, there are no established criteria upon which to base a decision regarding the need for a walking aid. It appears clinicians prescribe aids based on preference, clinical experience and intuition rather than standardised objective rationale. This may contribute to the inconsistent gait response to walking aids reported in the published literature. Understanding gait changes resulting from gait aid usage may have significant impact on clinical practice by improving confidence of prescribing clinicians and compliance of walking aid usage by patients, maximising the benefits of use, and reducing any risks associated with non-use or inappropriate use, of the walking aid. Research question: Do professionally prescribed walking aids improve gait parameters? Methods: This is a secondary data analysis of a cross-sectional study where participants, identified by healthcare staff requiring a mobility assessment due to potential balance impairment of any cause, walked a 20-m straight walking course under three different walking conditions (no aid, walking stick and 4-wheeled walker). Fifty-eight participants were recruited. Commonly reported spatial and temporal gait parameters were assessed using a validated gait analysis device. Changes in gait parameters across the three conditions were compared, noting the individual's professionally prescribed aid and interpreting changes in parameters towards outcomes of the 'no aid required group'. Results and significance: Gait cycle, cadence, stance, swing and stride length during unaided walking were significantly changed when a walking stick was prescribed (p < 0.05). Stance, swing, double support, stride length, speed, max toe clearance and minimum toe clearance were significantly changed when a 4-wheel walker was prescribed (p < 0.05). Professional walking aid prescription improves some gait parameters. A greater number and magnitude of gait parameter improvements were seen in people requiring a 4-wheel walker than people requiring a walking stick.

Objective: Patients diagnosed with idiopathic Normal Pressure Hydrocephalus (iNPH) typically experience symptom improvements after undergoing a cerebrospinal fluid-tap test (CSF-TT), These improvements are recognized as indicative of potential improvements following surgical intervention. As gait disturbance is the most common iNPH symptom, gait improvements are of predominant interest. The purpose of this study was to examine if clinically important changes in gait and balance from CSF-TT predict meaningful changes following surgery. Method: The study involved analysis of data collected in a prospective observational study for 34 iNPH patients who underwent a CSF-TT and subsequent surgery. Linear regression, logistic regression and classification trees were used for predictive modelling comparing changes from CSF-TT with post-surgical changes in Tinetti, Timed Up and Go (TUG) and Berg Balance Scale (BBS) outcomes. Results: Predictive models for minimal clinically important differences (MCIDs) from CSF-TT to surgery were significant for Tinetti (odds ratio = 1.42, p = 0.02) and BBS (odds ratio = 1.57, p < 0.01). Four items on Tinetti and two items on BBS were identified with a predictive accuracy of 79% and 76% respectively. BBS has the highest sensitivity (85%) and negative predictive value (77%). TUG had a 100% specificity and 100% positive predictive value. The predictive model using MCIDs for TUG was not significant (odds ratio = 1.13, p = 0.06). Conclusion: Clinically important changes from CSF-TT are useful in predicting post-surgical outcomes in iNPH patients. Tinetti and BBS, both have predictive value using MCID scores as cut off values, of which BBS is a stronger outcome measure for prediction.

Objective: The purpose of this study was to determine the normal range of rotation occurring during rotation stress testing for alar ligament integrity and to ascertain whether rotation range on testing is affected by an individual's age. Method: In this observational study, 88 people aged 18 to 86 years old with no current neck problems or known risk factors for craniocervical instability underwent rotation stress testing for the alar ligaments. The test was performed in each direction in neutral, flexion, and extension, with the participant both sitting and supine. Rotation range was recorded using an electromagnetic movement tracking system. Range was assessed overall and then compared by 10-year age groups using analysis of variance. Reliability of measurements was assessed by intraclass correlation coefficient(2,1) and standard error of measurement. Results: Mean angles of upper cervical rotation ranged between 10.91° (standard deviation 3.38°) to 16.12° (standard deviation 5.13°). Overall measured rotation ranged from 1.37° to 33.22°. Participants in older age groups generally displayed reduced rotation; however, the reduction was less than 4°. Reliability of rotation measurements was good to excellent, with the intraclass correlation coefficient ranging from 0.80 to 0.99. Conclusions: Normal range of rotation measured during stress testing for the alar ligament varied widely but did not exceed 33o. All values measured in this study fell below recommendations for ligament integrity. Age-related change was not clinically significant in the interpretation of this test in this asymptomatic population.

Overweight and obesity increase the risk of development and progression of knee osteoarthritis (OA), with higher levels of fat mass and lower levels of lean mass associated with poorer functional status. The aim was to assess changes in weight, body composition and physical function following weight loss or weight maintenance interventions in knee OA. A comprehensive search of four databases was conducted. The risk of bias was assessed using the Quality Criteria Checklist for primary research. Primary outcomes included weight, body composition and physical function; secondary outcomes were lipids, inflammatory biomarkers and muscle strength. Eleven studies were included utilizing diet and exercise (n = 4) or diet-only (n = 7) interventions, two of which were weight maintenance studies. Most studies (n = 10) reported improvements in physical function with significant weight loss, while the change in strength reported in three studies was variable. The diet and exercise studies reported an average reduction in weight of 6.7% and lean mass of 1.6 kg, with greater improvements in physical function. The diet-only studies, including weight maintenance interventions, reported greater average weight loss (7.8%) and reduction in LM (2.0 kg). Overall, better retention of lean mass and muscle strength was observed in participants with higher protein intake (=37% of energy) and subsequently improved physical function.

Background: Descriptions of the radiological appearance of the craniovertebral ligaments often lack detail. This study aimed to provide an accurate description of the morphology and radiological appearance of the alar and cruciform ligaments with confirmation of findings by fine dissection. Materials and Methods: Six embalmed human cadaveric specimens were reduced to an osseoligamentous arrangement spanning the C2/3 disc to the occiput. Specimens were imaged on a 4.6T Bruker magnetic resonance (MR) system using a 3D RARE multiple SE sequence with acquisition time 18 h 24 min. Acquired images were viewed in three planes, and detailed descriptions and morphometric measurement of the ligaments were obtained. Specimens were then examined and described using fine dissection. Direct comparison of the descriptions of each method was undertaken. Results: From imaging, detailed features of all alar ligaments could be identified in all specimens. Consistency in shape, orientation, and attachments is described. Attachment to the medial aspect of the atlantooccipital joints was evident in all specimens. Five of six alar ligament pairs contained fibers that traversed the dens without attachment. Ascending cruciform ligaments could be clearly identified in four of six specimens. No descending cruciform ligaments could be clearly delineated. Detailed features of the transverse ligaments could be identified and described in all planes. Dissection findings were mostly consistent with descriptions obtained from MR images. Conclusion: 4.6T MR images provide accurate detail of the structure, dimensions, and attachments of the craniovertebral ligaments. The morphology of the craniovertebral ligaments assessed radiologically was consistent with findings on gross dissection.

Neck pain is a common complaint among fighter aircrew, impacting workforce health and operational capability. This systematic review aimed to identify, evaluate and synthesise the current evidence for factors associated with the occurrence of neck pain among fighter aircrew. Six electronic databases were searched in June 2019 and updated in June 2020 utilising the maximum date ranges. Included studies were appraised for methodological quality, ranked according to level of evidence and relevant data extracted. Where methods were homogeneous and data availability allowed, meta-analyses were performed. A total of 20 studies (16 cross sectional, one case-control, one retrospective cohort and two prospective cohort) were eligible for inclusion. Of the 44 factors investigated, consistent evidence was reported for greater occurrence of neck pain among aircrew operating more advanced aircraft and those exposed to more desk/computer work, while another 12 factors reported consistent evidence for no association. Of the 20 factors where meta-analyses could be performed, greater occurrence of neck pain was indicated for aircrew: flying more advanced aircraft, undertaking warm-up stretching and not placing their head against the seat under greater +Gz. Despite many studies investigating factors associated with neck pain among fighter aircrew, methodological limitations limited the ability to identify those factors that are most important to future preventive programmes. High-quality prospective studies with consistent use of definitions are required before we can implement efficient and effective programmes to reduce the prevalence and impact of neck pain in fighter aircrew. PROSPERO registration number: CRD42019128952. Neck pain is a common complaint among fighter aircrew, impacting workforce health and operational capability. This systematic review aimed to identify, evaluate and synthesise the current evidence for factors associated with the occurrence of neck pain among fighter aircrew.

Background: Clinically, a discrepancy of fibular position in relation to the tibia has been proposed as a factor in the persistence of chronic ankle instability (CAI). Previous studies have produced conflicting findings, perhaps due to varying radiological methods and measurement of participants in non-weight-bearing positions. Objectives: To compare normalized-fibular position in weight-bearing in individuals with CAI with healthy controls. Design: A weight-bearing lateral X-ray was taken of the affected ankle of 33 adults with CAI and 33 matched controls. The distance between the anterior edges of the distal fibula and tibia was recorded, and then normalized as a proportion of maximal tibial width. Normalized-fibular position was compared between groups using independent t-tests. Intra-class correlation coefficients (ICC2,1) were calculated to determine reliability of measurements. A receiver-operating characteristic (ROC) curve was used to determine sensitivity, specificity, and a cutoff score to differentiate individuals with CAI from controls using normalized-fibular position. Results: Normalized fibular position was significantly different (CAI, 29.7 (6.6)%; healthy, 26.7 (4.8)%) between the groups. Measurement of intra-rater (0.99, 95%CI¿=¿0.98 to 1.00) and inter-rater (0.98, 95%CI¿=¿0.96 to 0.99) reliability were both excellent. The threshold normalized-fibular position was 27%, with a score more than 27% indicating a greater chance of being in the CAI group. Sensitivity was 69.7% and specificity was 54.5% for this threshold. Conclusion: A slightly anteriorly positioned fibula in relation to the tibia was observed in people with CAI. Specificity/sensitivity scores for normalized-fibular position indicate that it has little ability to predict CAI alone.

Background: The COVID-19 pandemic has altered clinical practice and education in manual therapy globally. Social distancing has limited in-person care and changed health-care provision. Education in manual therapy has moved to online platforms with in-person instruction restricted. The global impact on the clinical practice of manual therapy and education has to date not been explored. Methods: a questionnaire survey methodology was used. A sample of convenience of global leaders in manual therapy practice and education received an electronic link to two surveys: one on clinical practice and one on education. Contributors could complete one or both surveys. Results: Twenty-five surveys were received on clinical practice and 23 on education in manual therapy, representing the six major continents. Global themes in clinical practice demonstrated a sudden and dramatic shift away from patient contact, with limited modifications to manual therapy in patient care currently adopted. Themes in education were of a major shift to online learning, development of new modes of student instruction including video-based assessment and virtual case-based instruction. Conclusion: The international perspectives provided demonstrate a major change in manual therapy practice and education globally. Various approaches have been taken in practice and education without a uniform approach being demonstrated.

Objective: The aim of this study was to determine the diagnostic criteria used in randomized controlled trials to define trial participants as having cervicogenic headache (CeH). Background: While animal and human studies suggest a biological basis for "cervicogenic" headaches the diagnostic criteria necessary to evidence CeH are debated. Methods: A systematic review was undertaken guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. An electronic search of MEDLINE, Cochrane, CINHAL, Pedro, AMED, and EMBASE online databases of randomized controlled trials published between January 1983 and October 2018 found 39 randomized controlled trials which met the study inclusion criteria. Results: Two independent reviewers found most trials cited 1 (31/39; 79.5%) or more (3/39; 7.6%) references to define the criteria used to identify CeH in their study participants. In spite of updated publications concerning the characteristics and definition of CeH, many (27/39; 69.2%) used diagnostic criteria published between 5 and 24¿years prior to the randomized controlled trial. The most commonly cited diagnostic criteria included unilateral headache (18/39; 46.2%), cervical movement or sustained posture that either provoked (18/39; 46.2%) or precipitated (17/39; 43.6%) the headache. Fifteen trials did not exclude participants with signs or symptoms of other forms of headache. Although anesthetic blockade of cervical tissue or nerves is considered necessary for a "definitive" diagnosis, only 7.6% (3/39) of trials used anesthetic blockade at recruitment. Conclusions: This systematic review evidences the heterogeneity in the clinical characteristics used to diagnose CeH in participants recruited in randomized controlled trials. It raises a significant concern about the usefulness of currently available randomized controlled trials to determine the clinical merits of the treatment and management of people with CeHs. Our systematic review suggests that most randomized controlled trials published to date have investigated headaches with a clinical presentation involving the neck that maybe better defined as "possible," "probable," or "definitive" CeH depending on how well the diagnostic criteria used align with the most recent edition (3rd) of the International Classification of Headache Disorders.

Objective: The composition of cervical-spine meniscoids may have clinical significance in neck-pain conditions, but the accuracy of assessment of meniscoid composition in vivo using magnetic resonance imaging has not been established. The aim of this study was to compare cervical-spine meniscoid composition by magnetic resonance imaging with histologic composition. Methods: Four embalmed cadaveric cervical spines (mean [standard deviation] age, 79.5 [3.7] years; 1 female, 3 male) underwent magnetic resonance imaging, allowing radiologic classification of lateral atlantoaxial- and zygapophyseal-joint (C2-3 to C6-7) meniscoids as either mostly fatty, mixed tissue, or mostly connective tissue. Subsequently, each joint was dissected and disarticulated to allow excision of meniscoids for histologic processing. Each meniscoid was sectioned sagittally, stained with hematoxylin and eosin, examined using light microscopy, and classified as adipose, fibroadipose, or fibrous in composition. Data were analyzed using the kappa statistic with linear weighting. Results: From dissection, 62 meniscoids were identified, excised, and processed; 46 of these 62 were visualized with magnetic resonance imaging. For single-rater identifying structures, agreement between assessment of meniscoid composition by magnetic resonance imaging and by microscopy was fair (¿ = 0.24; 95% confidence interval, 0.02-0.46; P = .02). Conclusion: Findings suggest that the accuracy of this method of magnetic resonance imaging assessment of cervical-spine meniscoid composition may be limited. This should be considered when planning or interpreting research investigating meniscoid composition using magnetic resonance imaging.

Background: Cervical sensorimotor control (CSMC) outcomes have been suggested to be important in the assessment of individuals with neck pain, despite the lack of consistent supporting evidence that CSMC skills are related to neck pain. Objective: The aim of this study was to investigate whether CSMC changes over time in individuals with chronic idiopathic neck pain and whether neck pain characteristics are associated with CSMC. Design: A longitudinal observational study was performed. Methods: A total 50 participants with chronic idiopathic neck pain and 50 matched participants who were healthy (controls) completed 7 CSMC tests (including 14 test conditions): joint position error, postural balance, subjective visual vertical, head tilt response, The Fly, smooth pursuit neck torsion, and head steadiness. Neck pain characteristics included pain intensity (visual analog scale), pain duration, and neck disability (Neck Disability Index). Linear mixed models were used to investigate whether any factors were associated with changes in CSMC. Results: Neck pain intensity was associated with 1 of 14 CSMC test conditions (balance with torsion and eyes open), and neck disability was associated with balance with eyes open and high-load head steadiness. Other factors, including sex, age, body mass index, physical activity levels, and neck pain duration, showed no association with CSMC. Limitations: Although all other tests involved computerized data collection, the joint position error test was administered manually, introducing the risk of researcher bias. Conclusions: The few associations between test conditions and neck pain characteristics were at best weak; hence, these are likely to be chance findings. These results suggest that CSMC may not be associated with improvement/worsening of chronic idiopathic neck pain, spawning debate on the clinical usefulness of CSMC tests.

Background: Sensorimotor control is commonly reported in neck pain research and rapidly gaining interest in clinical practice. Joint position error (conventional and torsion), postural balance, subjective visual vertical, head tilt response, The Fly®, smooth pursuit neck torsion and head steadiness are tests that have been reported to assess cervical sensorimotor control. However, it is unknown whether clinicians could use one test, or a test battery, to appropriately assess cervical sensorimotor control and improve efficiency. Our main research question is: Do seven cervical sensorimotor control tests measure unique or similar characteristics of sensorimotor control in individuals with chronic idiopathic neck pain? Methods: Principle components factor analysis. Data from seven cervical sensorimotor control tests of 50 participants with chronic idiopathic neck pain were included. Individual factors, potentially related to sensorimotor control, were determined by Eigen values >1.00 and inspection of a loading plot. Items with loadings =0.40 were considered satisfactory for inclusion in a factor. Results: All cervical sensorimotor control tests were found to measure unique skills. Four factors were isolated with two, postural balance and head steadiness, accounting for most of the variance across tests. The remaining two factors, continuous movement accuracy and perceived verticality, contributed less to the observed variance. Conclusion: Postural balance and head steadiness were the major underlying factors explaining cervical sensorimotor control in the current sample. However, our results imply that all seven tests are independent and measure different skills. It is not possible to recommend a test battery for clinical practice, as all tests measure unique skills which appear to be independent of each other.

BACKGROUND: Idiopathic normal pressure hydrocephalus (iNPH) is treated by insertion of a ventricular peritoneal (VP) shunt. To help identify who would benefit from a VP shunt, patients undergo a tap test (TT). Several measures can identify change from a TT, but the magnitude of change and the combination of measures that indicate the improvement from a TT is unclear. OBJECTIVE: To develop minimal clinically important differences (MCIDs) for a battery of gait, balance, and cognitive measures in relation to improvement from the TT, and to identify which combination of measures best identifies when improvement has occurred. METHODS: Observational study of iNPH patients undergoing a TT for consideration of a VP shunt. Patients completed the: The Timed Up and Go (TUG), Timed Up and Go cognition (TUG-C), Performance Oriented Mobility Assessment (Tinetti), and Berg Balance Scale (BBS) pre- and post-TT. A Global Rating of Change scale assessed patients' perceived improvements in gait and balance post-TT. RESULTS: MCIDs for the TT were (calculated as percentage changes): TUG: 13%, TUG-C: 11% Tinetti: 36%, and BBS: 20%. A combination of the TUG-C and Tinetti resulted in sensitivity of 90.28% to identify improvement, while the Tinetti and BBS resulted in specificity of 98.58% to exclude improvement from a TT. CONCLUSION: These MCIDs provide the first evidence to quantify the significance of post-TT symptom changes and provides objective data to guide recommendations for clinical management. Utilizing a combination of measures, and these MCIDs as cut off values, results in high sensitivity and specificity for identifying improvement from a TT.

Objective: To systematically review whether there is an association between hip range of motion (ROM) and nonspecific low back pain (NSLBP). Data sources: MEDLINE, EMBASE, Cochrane library, PsychINFO, CINAHL and AMED databases were searched from year of inception until October 31st, 2018, using a combination of LBP and hip joint search terms. Commonly cited journals were also hand searched within the previous two years. Study selection: Two reviewers independently screened identified articles, by title and abstract and then by full-text. After first round screening of 2908 identified records, 248 progressed to full-text screening. Due to the heterogeneity of studies identified, post hoc inclusion criteria of English language, studies comparing subjects with NSLBP and healthy controls, cross-sectional design, and clinical measures of hip ROM were applied. Twenty-four records were finally included. Data extraction: Extracted data included population characteristics, duration and severity of NSLBP, hip movement direction, testing position, measurement tool and between-group difference. The Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to assess for study bias. Data synthesis: Hip flexion ROM was measured in seven studies, extension in 13, internal rotation (IR) in 14, external rotation (ER) in 13, abduction in six, and adduction in only two studies. Among all directions tested, IR ROM was reported in more studies as significantly reduced in NSLBP subjects compared to healthy individuals. Overall the quality of evidence was very low. Common sources of study bias included lack of sample size justification, blinding of outcome assessors, adjusting for key confounders, and poor reporting. Conclusion: There is very low-quality evidence to support an association between limited hip ROM and NSLBP. Limited hip IR ROM was the only movement impairment found to be significantly associated with NSLBP, however this should be viewed with caution due to the low-quality supportive evidence. Further studies are needed.

Objective: To assess the clinical benefits of joint mobilization for ankle sprains. Data Sources: MEDLINE, MEDLINE In-Process, Embase, AMED, PsycINFO, CINAHL, Cochrane Library, PEDro, Scopus, SPORTDiscus, and Dissertations and Theses were searched from inception to June 2017. Study Selection: Studies investigating humans with grade I or II lateral or medial sprains of the ankle in any pathologic state from acute to chronic, who had been treated with joint mobilization were considered for inclusion. Any conservative intervention was considered as a comparator. Commonly reported clinical outcomes were considered such as ankle range of movement, pain, and function. After screening of 1530 abstracts, 56 studies were selected for full-text screening, and 23 were eligible for inclusion. Eleven studies on chronic sprains reported sufficient data for meta-analysis. Data Extraction: Data were extracted using the participants, interventions, comparison, outcomes, and study design approach. Clinically relevant outcomes (dorsiflexion range, proprioception, balance, function, pain threshold, pain intensity) were assessed at immediate, short-term, and long-term follow-up points. Data Synthesis: Methodological quality was assessed independently by 2 reviewers, and most studies were found to be of moderate quality, with no studies rated as poor. Meta-analysis revealed significant immediate benefits of joint mobilization compared with comparators on improving posteromedial dynamic balance (P=.0004), but not for improving dorsiflexion range (P=.16), static balance (P=.96), or pain intensity (P=.45). Joint mobilization was beneficial in the short-term for improving weight-bearing dorsiflexion range (P=.003) compared with a control. Conclusions: Joint mobilization appears to be beneficial for improving dynamic balance immediately after application, and dorsiflexion range in the short-term. Long-term benefits have not been adequately investigated.

Background: neck pain and injury are common in rugby union. physical characteristics predisposing players to neck injury are largelyunknown. This study aimed to determine physical characteristics associated with neck pain and injury in rugby union players.MeThodS: Semi-professional rugby union players (n.=142) underwent pre-season measurements including cervical active range of motion(aroM), strength, sensorimotor proprioception (joint position error), and anthropometry. a structured interview established previous neckinjury history, current symptoms, playing position, competition level, age, and years playing rugby. Team physiotherapists and player telephoneinterviews identifed players sustaining a neck injury during the competitive season (defned as any reported neck pain or neck injury). T-tests orMann-Whitney u tests determined differences between neck injured and non-injured players. logistic regression determined factors associatedwith neck injury history and incidence.RESULTS: Sixty-fve (46%) players reported a previous neck injury; 11 (8%) sustained a neck injury during the competitive season. Player age(OR 1.14, 95% CI 1.03-1.25, P=0.009) was associated with neck injury history. Pre-season lateral flexion AROM was less in players sustaininga neck injury or reporting neck pain during the season (median left 23.6°, IQR 21.8-26.2°; right 27.9°, 23.6-32.5°) than in other players (left34.8°, 28.8-41.0°, P<0.01; right 39.1°, 28.9-48.1°, P=0.03). Lateral flexion AROM was associated with increased risk of neck pain or injury (OR0.82, 95%ci 0.71-0.94, p=0.005).CONCLUSIONS: Decreased cervical lateral flexion AROM may contribute to neck injury risk in rugby union players. However, few physicalcharacteristics predicted neck injury incidence, suggesting additional factors should be explored to determine injury risk.

Context: Scapular taping can offer clinical benefit to some patients with shoulder pain; however, the underlying mechanisms are unclear. Understanding these mechanisms may guide the development of treatment strategies for managing neuromusculoskeletal shoulder conditions. Objective: To examine the mechanisms underpinning the benefits of scapular taping. Design: Descriptive laboratory study. Setting: University laboratory. Patients or Other Participants: A total of 15 individuals (8 men, 7 women; age ¼ 31.0 6 12.4 years, height ¼ 170.9 6 7.6 cm, mass ¼ 73.8 6 14.4 kg) with no history of shoulder pain. Intervention(s): Scapular taping. Main Outcome Measure(s): Surface electromyography (EMG) was used to assess the (1) magnitude and onset of contraction of the upper trapezius (UT), lower trapezius (LT), and serratus anterior relative to the contraction of the middle deltoid during active shoulder flexion and abduction and (2) corticomotor excitability (amplitude of motor-evoked potentials from transcranial magnetic stimulation) of these muscles at rest and during isometric abduction. Active shoulder-flexion and shoulder-abduction range of motion were also evaluated. All outcomes were measured before taping, immediately after taping, 24 hours after taping with the original tape on, and 24 hours after taping with the tape removed. Results: Onset of contractions occurred earlier immediately after taping than before taping during abduction for the UT (34.18 6 118.91 milliseconds and 93.95 6 106.33 milliseconds, respectively, after middle deltoid contraction; P ¼ .02) and during flexion for the LT (110.02 6 109.83 milliseconds and 5.94 6 92.35 milliseconds, respectively, before middle deltoid contraction; P ¼ .06). These changes were not maintained 24 hours after taping. Mean motor-evoked potential onset of the middle deltoid was earlier at 24 hours after taping (tape on ¼ 7.20 6 4.33 milliseconds) than before taping (8.71 6 5.24 milliseconds, P ¼ .008). We observed no differences in peak root mean square EMG activity or corticomotor excitability of the scapular muscles among any time frames. Conclusions: Scapular taping was associated with the earlier onset of UT and LT contractions during shoulder abduction and flexion, respectively. Altered corticomotor excitability did not underpin earlier EMG onsets of activity after taping in this sample. Our findings suggested that the optimal time to engage in rehabilitative exercises to facilitate onset of trapezius contractions during shoulder movements may be immediately after tape application.

Objectives: To determine which cognitive and upper limb assessments can identify change in patients undergoing a Cerebrospinal fluid (CSF) tap test (TT) diagnosed with idiopathic Normal Pressure Hydrocephalus (iNPH). Patients and methods: Prospective observational study of 74 iNPH patients undergoing a CSF TT for consideration of a ventricular peritoneal shunt. Patients who were offered surgical intervention were classified as responders. Patients were assessed with a battery of cognitive and upper limb assessments prior to and following a CSF TT. The Timed up and go cognition (TUG-C), Montreal Cognitive assessment (MoCA) and 9-hole peg test were utilised. Results: 40 patients were classified responders. Significant differences were identified for responders for the MoCA (0.62 points) and TUG-C (-6.02 s). Only the executive function and orientation sub scores of the MoCA showed significant changes for responders. The 9 hole peg test mean change of 4.33 s for responders was not significant. Non-responder change scores for the MoCA (0.22 points), TUG-C (0.3 s) and 9 hole peg test (2.58 s) were not significant. Conclusion: The TUG-C has the potential to identify change in patients resulting from a CSF TT. While statistically significant change was found for the MoCA, a mean change of less than 1 point on this scale is unlikely to be clinically relevant. Similarly, the 9 hole peg test cannot be endorsed as an assessment tool for identifying changed performance in iNPH.

Background Lateral atlantoaxial (LAA) joints are established sources of nociceptive input in chronic whiplash associated disorder (WAD). These joints contain intra-articular meniscoids that may be damaged in whiplash trauma. LAA joint meniscoid morphology has not been investigated comprehensively in a chronic WAD population, and it is unclear whether morphological differences exist compared to a pain-free population. Objectives This study examined LAA joint meniscoid volume in individuals with chronic WAD who report pain in a distribution consistent with LAA joint pain. Design Case-control study. Method Fourteen individuals with chronic WAD with pain in an LAA joint distribution (mean [SD] age 38.1 [10.8] years; six female) and 14 age- and sex-matched pain-free controls (38.0 [10.5] years) underwent cervical spine magnetic resonance imaging. LAA joint images were inspected for meniscoids; meniscoid volume was calculated in mm3 and as a percentage of articular cavity volume. Symptom duration, location and intensity were recorded. Data were analysed using paired t-tests, Wilcoxon signed-rank testing, Spearman's rank testing, linear and logistic regression (a < 0.05). Results Ventral and dorsal meniscoids (n = 112) were found in each LAA joint. Greater dorsal meniscoid volume as a percentage of articular cavity volume was associated with higher pain intensity (odds ratio 1.48, p = 0.03; likelihood ratio test chi-square2 = 6.64, p = 0.04), however no significant differences existed between meniscoid volumes of WAD and control participants. Conclusions Findings indicate a potential link between dorsal LAA joint meniscoid volume and pain, suggesting larger meniscoid size may have pathoanatomical significance in WAD.

Objectives: To identify in patients with idiopathic normal pressure hydrocephalus (iNPH) undergoing a cerebrospinal fluid (CSF) tap test (TT) for consideration of a ventricular peritoneal (VP) shunt: (1) gait and balance measures, which identify symptom change; (2) differences present between pre¿ and post¿CSF TT scores between patients classified as responders and nonresponder; (3) ability of patients with iNPH to accurately quantify change in their gait and balance symptoms from a CSF TT. Design: Prospective observational study. Post¿CSF TT assessment was completed 2-4 hours post. Setting: Tertiary referral neurological and neurosurgical hospital. Participants: Patients (N=74) with iNPH receiving a 30 mL CSF TT for consideration of a VP shunt. Interventions: Patients underwent a battery of gait and balance measures pre¿ and post¿CSF TT and indicated their perceived change on a global rating of change (GRC). Patients deemed to improve and offered VP shunt insertion by a neurologist or neurosurgeon were labeled responders. Main Outcome Measures: Performance oriented mobility assessment (Tinetti), Berg Balance Scale (BBS), timed Up and Go (TUG), 10-meter walk test (10MWT), GRC. Results: Forty patients were classified responders, 34 nonresponders. Significant differences were identified for responders: Tinetti (3.88 points), TUG (3.98 seconds), 10MWT (0.08 m/sec), and BBS (5.29 points). Significant differences were found for nonresponders for the Tinetti (0.91 points) and BBS (2.06 points). Change scores for responders and nonresponders were significantly different for all tests between responders and nonresponders. GRC scores for gait (+2 for responders, 0 for nonresponders) and balance (+2.5 for responders, 0 for nonresponders) were both significantly different. Conclusions: The Tinetti, BBS, and TUG can identify change in patients undergoing a CSF TT for iNPH. Patients appear to be able to accurately identify if change has occurred.

Purpose: Cervical spine meniscoids are intra-articular folds of synovial membrane that have been theorised to have potential clinical significance in neck pain. Recent anatomical and clinical research has re-visited the pathoanatomical capacity of these structures. The purpose of this review is to discuss cervical spine meniscoid morphology in light of recently published work, to provide an update on the plausible relevance of these structures to clinical practice. Methods: Narrative review critically discussing basic science and clinical research regarding cervical spine meniscoids, with focus upon implications for clinical practice. Results: Basic science research indicates that cervical spine meniscoids can be innervated and appear to vary in morphology in the presence of articular degeneration. In a clinical population, associations have been observed between cervical spine meniscoid morphology and presence of cervical spine symptoms. Conclusions: Recent studies regarding cervical spine meniscoid morphology provide further evidence of pathoanatomical capacity of these structures. Further research is required, however, in clinical populations to empirically investigate specific theorised mechanisms of cervical spine meniscoid involvement in neck pain.

Objectives To report normative responses to the HAGOS questionnaire for Australian football players and to determine whether any of the HAGOS questionnaire sub scales can differentiate players with and without groin pain. Design Case-control. Setting Clinical setting. Participants Professional (n = 66) and semi-professional (n = 9) Australian football (AF) players with current groin pain (n = 16) and controls (n = 57) without current groin pain. Main outcome measure The HAGOS subscales were compared between players with and without groin pain using the Wilcoxon rank-sum test with effect sizes (ES) calculated. Floor and ceiling effects were examined. A post-hoc factor analysis was undertaken. Results Participants with current groin pain showed lower Physical Function of Daily Living (PFDL) and Physical Function in Sport and Recreation (PFSR) subscale scores (p < 0.05, ES: 0.77 and 0.90 respectively). Any groin pain (current and/or historical) lowered the Pain and Quality of Life (QOL) subscale scores (p < 0.05, ES: 0.38 and 0.72 respectively). Factor analysis showed 8 significant factors with one main factor identified representing items describing forceful activities (Eigenvalue = 18.02, Proportion = 0.49). Conclusions The HAGOS can distinguish AF players with current groin pain in the PFDL and PFSR subscales but not in the other four subscales. Any current or historical groin pain lowers scores on the QOL and Pain sub scales. Level of evidence Aetiology, Individual Case-Control Study, Level 3b

Objectives: The aim of this study was to systematically review the literature concerning proton magnetic resonance spectroscopy (H-MRS) measured glutamate levels in specific brain regions of fibromyalgia (FM) patients to determine if there is a correlation between raised glutamate levels and the presentation of FM. Materials and Methods: The electronic databases-MEDLINE, EMBASE Classic+Embase, PsychINFO, Cochrane Database of Systematic Reviews, Cochrane Database of Abstracts of Reviews of Effect, Cochrane Central Register of Controlled Trials-were searched to find original studies that used H-MRS to measure glutamate concentrations in the brains of FM patients. Results: Nine studies with a total of 482 participants were selected for inclusion in the review. Seven of the 8 studies that investigated an association between cerebral glutamate levels and FM, showed a positive association. Brain regions identified as having increased glutamate levels include the posterior cingulate gyrus, posterior insula, ventrolateral prefrontal cortex, and amygdala. One study reported a decrease in glutamate levels in the hippocampus of FM patients compared with healthy controls. Seven of the 8 studies that analyzed the correlations between cerebral glutamate levels and FM symptoms, found a significant positive correlation. Discussion: Although the cause of FM remains inconclusive, there is converging data in favor of a dysregulation of pain processing in the central nervous system of FM patients, particularly associated with an increase in cerebral glutamate levels. Furthermore, there is evidence to support an association between increased glutamate levels and an increase in FM symptoms.

Objective: To describe the geographical distribution of physiotherapy clinical placements and investigate the relationship between geographical setting and clinical placement marks in physiotherapy students. Design: A retrospective cohort design was used for this study. Setting: The University of Newcastle, New South Wales. Participants: Data from entry-level Bachelor of Physiotherapy student clinical placements. Main outcome measure(s): Data from all clinical placements in the Physiotherapy program between 2003 and 2014 were included. For all clinical placements, student assessment mark, year of study, type of placement and placement location were collected. Placement location was then classified using the Modified Monash Model (MMM) categories: one (most metropolitan) to seven (most remote). Results: Over the 12¿year period of the study 3964 placements were completed. Between 2003 and 2005 the average proportion of clinical placements occurring in metropolitan areas (MMM1) was 78% and in rural areas (MMM categories 3¿6) was 22%. In 2014 these proportions had changed to 59% (MMM1) and 40% (MMM3-6). There were significant differences in clinical placement grades between MMM1 and all other categories except MMM2, with lower assessment marks in MMM1 than other categories. Conclusions: The changing distribution of physiotherapy clinical placements may be reflective of increasing student numbers and greater efforts to support students completing rural and remote placements. This change may lead to a positive effect on the rural and remote physiotherapy workforce. Further research is required to determine the specific training and support needs of students and clinical educators in rural and remote settings.

Objectives This is the first study to evaluate the mechanical sensitivity, clinical classifications and prevalence of groin pain in Australian football players. Design Case-control. Methods Professional (n = 66) and semi-professional (n = 9) Australian football players with and without current or previous groin injuries were recruited. Diagnoses were mapped to the Doha Agreement taxonomy. Point and career prevalence of groin pain was calculated. Pressure pain thresholds (PPTs) were assessed at regional and distant sites using handheld pressure algometry across four sites bilaterally (adductor longus tendon, pubic bone, rectus femoris, tibialis anterior muscle). To assess the relationship between current groin pain and fixed effects of hyperalgesia of each site and a history of groin pain, a mixed-effect logistic regression model was utilised. Receiver Operator Characteristic (ROC) curve were determined for the model. Results Point prevalence of groin pain in the preseason was 21.9% with a career prevalence of 44.8%. Adductor-related groin pain was the most prevalent classification in the pre-season period. Hyperalgesia was observed in the adductor longus tendon site in athletes with current groin pain (OR = 16.27, 95% CI 1.86 to 142.02). The ROC area under the curve of the regression model was fair (AUC = 0.76, 95% CI 0.54 to 0.83). Conclusions Prevalence data indicates that groin pain is a larger issue than published incidence rates imply. Adductor-related groin pain is the most common diagnosis in pre-season in this population. This study has shown that hyperalgesia exists in Australian football players experiencing groin pain indicating the value of assessing mechanical pain sensitivity as a component of the clinical assessment.

The Timed Up and Go (TUG) and Two-Minute Walk Test (2MWT) are clinically appropriate mobility measures in amputee rehabilitation. Despite the tests being routinely performed, reference values for amputees have yet to be established. This study aimed to establish and trial a method for estimating normative values of the TUG and 2MWT for transtibial and transfemoral amputees. Thirty-seven established prosthetic users aged 40¿69 years (28 unilateral transtibial amputees and nine unilateral transfemoral) performed two recorded trials of the TUG and 2MWT. Participant characteristics were collected using the Trinity Amputation and Prosthesis Experience Scale. Preliminary normative data for the TUG and 2MWT were produced for three age cohorts and the two amputee subpopulations. Poorer mobility performance with transfemoral amputation was evident for both mobility measures. Multivariate analysis displayed relationships between age, length of time with a prosthesis and performance of both tests. In conclusion, normative values for the TUG and 2MWT for transtibial and transfemoral amputees may be calculated. Preliminary results indicate that higher levels of amputation relate to poorer performance on both the TUG and 2MWT. Studies with larger samples are required to further develop these values for use in rehabilitation.

The lateral atlantoaxial joints contain folds of synovium termed meniscoids that may potentially contribute to cervical spine pain; however, the anatomy of these structures has not been comprehensively investigated. The purpose of this study was to explore the morphology and morphometry of lateral atlantoaxial joint meniscoids. Twelve cadaveric hemi-spines (6 female; 6 left; mean 81.5¿years, SD 7.3) were obtained for dissection and disarticulation of the lateral atlantoaxial joints. Meniscoids were identified and measurements made of surface area, length, and surrounding articular cartilage degeneration. Tissue was sectioned sagittally, stained with hematoxylin and eosin, and examined by light microscopy. Data were analyzed descriptively and using nonparametric techniques. Ventral and dorsal meniscoids (24 in total) were found in each joint, and could be classified histologically into adipose (32¿%), fibrous (41¿%), and fibroadipose (27¿%) meniscoids. No significant associations were found between meniscoid size and age, histology, cartilage degeneration, or joint position. Meniscoid length in males was significantly greater than in females (P¿=¿0.04). Fibrous meniscoids were noted to be associated with articular cartilage degeneration, and adipose and fibroadipose meniscoids with intact cartilage (P¿=¿0.05). Fibrous meniscoids tended to be located dorsally (78¿%), whereas adipose meniscoids were mostly located ventrally (86¿%). Distinct patterns in lateral atlantoaxial joint meniscoid morphology were observed, including the association of fibrous meniscoid composition with dorsal joint position and articular cartilage degeneration. The clinical significance of these patterns remains uncertain, and further research is needed to examine these structures across the lifespan and in cervical pathology.

© 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd The criterion of long-standing groin pain diagnoses in athletes usually relies on palpation and clinical tests. An experimental pain model was developed to examine the clinical tests under standardized conditions. Pain was induced by hypertonic saline injected into the proximal adductor longus (AL) tendon or rectus femoris (RF) tendon in 15 healthy male participants. Isotonic saline was injected contralaterally as a control. Pain intensity was assessed on a visual analog scale (VAS). Resisted hip adduction at three different angles and trunk flexion were completed before, during, and after injections. Pain provocation in the presence of experimental pain was recorded as a true positive compared with pain provocation in the non-pain conditions. Similar p eak VAS scores were found after hypertonic saline injections into the AL and RF and both induced higher VAS scores than isotonic saline (P < 0.01). Adduction at 0° had the greatest positive likelihood ratio (+LR = 2.8, 95%CI: 1.09¿7.32) with 45° (-LR = 0.0, 95%CI: 0.00¿1.90) and 90° (-LR = 0.0, 95%CI: 0.00¿0.94) having the lowest negative LR. This study indicates that the 0° hip adduction test resisted at the ankles optimizes the diagnostic procedure without compromising diagnostic capacity to identify experimental groin pain. Validation in clinical populations is warranted.

FisheyeSTUDY DESIGN: Case-control study. FisheyeBACKGROUND: Cervical spine meniscoids are thought to contribute to neck pain and hypomobility in individuals with chronic whiplash-associated disorder (WAD); however, their morphology has not been studied in a clinical population. FisheyeOBJECTIVES: To investigate cervical spine meniscoid morphology in individuals with chronic WAD. FisheyeMETHODS: Twenty volunteers with chronic WAD (mean ± SD age, 39.3 ± 11.0 years; 10 female) and 20 age- and sex-matched controls (age, 39.1 ± 10.6 years) underwent cervical spine magnetic resonance imaging. Lateral atlantoaxial and zygapophyseal joints (C2-3 to C6-7) were inspected for meniscoids. Length of meniscoid protrusion was measured and composition (adipose/fibrous/fibroadipose) assessed. Data were analyzed using Wilcoxon signed-rank tests and linear and logistic regression (P<.05). FisheyeRESULTS: Meniscoids were identified in the chronic WAD (n = 317) and control (n = 296) groups. At the lateral atlantoaxial joints, median meniscoid length was greater in the control group (ventral, 6.07 mm; dorsal, 7.24 mm) than the WAD group (ventral, 5.01 mm; P = .06 and dorsal, 6.48 mm; P<.01). At the dorsal aspect of zygapophyseal joints, meniscoids were more frequently fibrous in the chronic WAD group (odds ratio = 2.38, P<.01; likelihood ratio test: ¿22, 9.02; P = .01). FisheyeCONCLUSION: In individuals with chronic WAD, lateral atlantoaxial meniscoids were shorter and dorsal cervical zygapophyseal meniscoids were more fibrous, suggesting alterations in meniscoid composition. This may have pathoanatomical implications in chronic WAD.

BACKGROUND: Musculoskeletal disorders represent a significant occupational health issue in dental hygiene, with high prevalence rates documented. Despite this fact, there have been few advancements in the application of ergonomic principles in the dental hygiene profession. While the use of loupes is often promoted as an ergonomic solution, there is little published research to support this claim. OBJECTIVES: The aim of the present study, therefore, was to investigate the effect of the use of loupes on neck pain and disability in dental hygienists. METHODS: The study was conducted using an exploratory pre-test post-test design, comparing musculoskeletal measures in dental hygienists wearing loupes with final year dental hygiene students who do not wear loupes. Pre- and post-test measures included the Neck Pain and Disability Scale and a standardised physical assessment using previously validated measures. Statistical analysis was conducted as a series of mixed ANOVAs with time and treatment as the independent variables. RESULTS: While the analyses revealed no significant interactions between time and treatment (p< 0.05), there were general trends of improvement or deterioration for outcome measures. Improvements over time were noted in the treatment group for cervical range of motion and deep neck muscle endurance; however deteriorations were noted for forward head posture and cervical kinaesthetic sense. CONCLUSIONS: Overall, despite no statistically significant differences being detected, this study suggests that wearing loupes appears to have both positive and negative outcomes with regards to physical well-being. As such, further studies are required to more precisely determine the effects of loupes on MSD among dental hygienists, particularly long-term. Dental hygienists with existing neck pain exploring ergonomic equipment may reflect on the findings and consider the potential benefits and risks of wearing loupes.

Background Shoulder pain and dysfunction after neck dissection may result from injury to the accessory nerve. The effect of early physical therapy in the form of intensive scapular strengthening exercises is unknown. Methods A total of 59 neck dissection participants were prospectively recruited for this study. Participants were randomly assigned to either the intervention group (n = 32), consisting of progressive scapular strengthening exercises for 12 weeks, or the control group (n = 29). Blinded assessment occurred at baseline, and at 3, 6, and 12 months. Results Three-month data were collected on 52 participants/53 shoulders. Per-protocol analysis demonstrated that the intervention group had statistically significantly higher active shoulder abduction at 3 months compared to the control group (+26.6°; 95% confidence interval [CI] 7.28-45.95; p =.007). Conclusion The intervention is a favorable treatment for maximizing shoulder abduction in the short term. The effect of the intervention compared to usual care is uncertain in the longer term.

Objectives To identify prognostic forms of clinical prediction rules (CPRs) related to the nonsurgical management of adults with low back pain (LBP) and to evaluate their current stage of development. Study Design and Setting Systematic review using a sensitive search strategy across seven databases with hand searching and citation tracking. Results A total of 10,005 records were screened for eligibility with 35 studies included in the review. The included studies report on the development of 30 prognostic LBP CPRs. Most of the identified CPRs are in their initial phase of development. Three CPRs were found to have undergone validation - the Cassandra rule for predicting long-term significant functional limitations and the five-item and two-item Flynn manipulation CPRs for predicting a favorable functional prognosis in patients being treated with lumbopelvic manipulation. No studies were identified that investigated whether the implementation of a CPR resulted in beneficial patient outcomes or improved resource efficiencies. Conclusion Most of the identified prognostic CPRs for LBP are in the initial phase of development and are consequently not recommended for direct application in clinical practice at this time. The body of evidence provides emergent confidence in the limited predictive performance of the Cassandra rule and the five-item Flynn manipulation CPR in comparable clinical settings and patient populations.

Objective The purpose of this study was to determine the intrarater reliability and reproducibility of a standardized procedure for measuring passive shoulder movement in asymptomatic individuals. Methods A single assessor used a digital inclinometer and standardized protocol to measure the passive range of motion of 7 shoulder movements in 168 asymptomatic shoulders. Following a warm-up maneuver, 3 measurements were taken for each movement on 2 occasions. Both shoulders were measured using a standardized order of movement. Selection of measurement beginning with left or right shoulder was randomly determined. The entire process was repeated 7 days later to assess reproducibility. Intraclass correlation coefficients (ICCs) with 95% confidence intervals and standard errors of measurement (SEMs) were calculated to assess the intrarater reliability of the methods. Results The intrarater reliability of our methods was substantial for total shoulder flexion (ICC = 0.82, SEM = 12.3°), whereas all other movements demonstrated moderate reliability (ICC range = 0.64-0.75) except external rotation in neutral abduction, for which reliability was classed as slight (ICC = 0.28, SEM = 31°). Moderate reliability was evident for all movements on follow-up at 7 days (ICC range = 0.60-0.77). Conclusions These methods of measurement have moderate to substantial reliability for the majority of tested passive shoulder movements, with moderate reliability sustained after 1 week, in a large sample of asymptomatic individuals.

Objective: To investigate evidence that intra-operative nerve monitoring of the spinal accessory nerve affects the prevalence of post-operative shoulder morbidity and predicts functional outcome.

Background. Adhesive capsulitis is often difficult to diagnose in its early stage and to differentiate from other common shoulder disorders. Objective. The aim of this study was to validate any or all of the 8 clinical identifiers of early-stage primary/idiopathic adhesive capsulitis established in an earlier Delphi study. Design. This was a cross-sectional study. Methods. Sixty-four patients diagnosed with early-stage adhesive capsulitis by a physical therapist or medical practitioner were included in the study. Eight active and 8 passive shoulder movements and visual analog scale pain scores for each movement were recorded prior to and immediately following an intra-articular injection of corticosteroid and local anesthetic. Using the local anesthetic as the reference standard, pain relief of >70% for passive external rotation was deemed a positive anesthetic response (PAR). Results. Sixteen participants (25%) demonstrated a PAR. Univariate logistic regression identified that of the proposed identifiers, global loss of passive range of movement (odds ratio [OR] =0.26, P=.03), pain at the end of range of all measured active movements (OR=0.06, P=.02), and global loss of passive glenohumeral movements (OR=0.23, P=.02) were associated with a PAR. Following stepwise removal of the variables, pain at the end of range of all measured active movements remained the only identifier but was associated with reduced odds of a PAR. Limitations. The lack of a recognized reference standard for diagnosing early-stage adhesive capsulitis remains problematic in all related research. Conclusions. None of the clinical identifiers for early-stage adhesive capsulitis previously proposed by expert consensus have been validated in this study. Clinicians should be aware that commonly used clinical identifiers may not be applicable to this stage. © 2014 American Physical Therapy Association.

Objectives: To evaluate patients clinically diagnosed with early stage primary/idiopathic adhesive capsulitis to determine the existence of any pattern of movement loss and associated pain that may facilitate early recognition. Design: Cross-sectional study. Setting: Private upper limb specialty clinic, Newcastle, Australia. Participants: Fifty-two patients clinically diagnosed with early stage adhesive capsulitis by a medical practitioner or physiotherapist. Main outcome measures: Percentage loss of active and passive ranges of eight shoulder movements and the pain level at the end of each movement. The reason for limitation of movement was also recorded. Results: Factor analysis clearly identified two groups for percentage loss of active range of movement. Notably external rotation movements grouped separately from other movements. A single group emerged for percentage loss of passive range of movement suggesting a non-specific global loss. For both pain at the end of active range of movement and passive range of movement two groups emerged, however the delineation between the groups was less clear than for percentage loss of active range of movement suggesting a pattern of end range pain may be less useful in identifying patients in this stage. Conclusions: External rotation movements in neutral and abduction generally group together and behave differently to other shoulder movements in patients clinically diagnosed with early stage primary/idiopathic adhesive capsulitis. In particular external rotation in abduction has emerged as the most painfully limited movement in this sample. This study provides preliminary evidence of patterns of range of movement and end range pain that require testing in a population of mixed shoulder diagnoses to determine their diagnostic utility for early stage adhesive capsulitis.

Cervicofacial lymphoedema is a recognised side-effect that may result following treatment for head and neck cancer. This study aimed to investigate the perspectives of affected patients and the beliefs that treating health professionals hold about head and neck lymphoedema. Ten patients with head and neck lymphoedema and 10 health professionals experienced in the treatment of head and neck cancer patients agreed to participate in semi-structured face to face interviews. Interviews were recorded, audio files were transcribed and coded and then analysed for themes. Themes of experiences of patients with head and neck lymphoedema and the beliefs of health professionals largely overlapped. Given its visible deformity, the main effect of lymphoedema in head and neck cancer patients was on appearance. In some cases this lead to negative psychosocial sequelae such as reduced self-esteem, and poor socialisation. Clinicians need to be aware of those patients more likely to experience lymphoedema following treatment for head and neck cancer, and how they are affected. Understanding how patients with facial lymphoedema are affected psychologically and physically, and the importance of prompt referral for lymphoedema treatment, might ultimately improve outcomes and ensure optimal management. © 2013 John Wiley & Sons Ltd.

Background and Objective: There is a paucity of information related to teaching palliative care to entry-level physical therapy students. The aim of this study was to evaluate the impact of an undergraduate course in palliative care on the preparedness of entry-level physical therapy students to practice within the palliative care setting. Methods: Participants were all entry-level undergraduate students enrolled in the third year of a 4-year undergraduate degree. All students enrolled in the course, "Physiotherapy Through Lifestages" took part in the learning modules relating to the care of patients undergoing palliative care. A survey instrument was used in the study, a modified version of an existing unpublished written questionnaire previously used to evaluate palliative care education in other allied health professions. Results and Conclusions: Participation in the course resulted in an increase in self-rated knowledge and confidence for working in the palliative care setting for entry-level physical therapy students and is considered to provide a useful ongoing resource for the presentation of this topic material. Although the impact of the delivery of this education module may be considered successful in this regard, it would appear that some of the underlying attitudes and emotional responses to this area of physiotherapy practice were less easily influenced. Further research is required to understand the influences on emotional preparedness of students to undertake this area of study and practice and to determine the optimal stage of study for delivery of this content. © Copyright 2014, Mary Ann Liebert, Inc.

Clinical Prediction Rules (CPRs) have been developed to assist in the physiotherapy management of low back pain (LBP) although little is known about the factors that may influence their implementation in clinical practice. This study used qualitative research methodology to explore the knowledge, attitudes and practices/behaviours of physiotherapists in relation to these tools. Four semi-structured focus groups involving 26 musculoskeletal physiotherapists were conducted across three Australian geographic regions. A fictitious LBP case scenario was developed and used to facilitate group discussion. Participant knowledge of CPRs was found to be mixed, with some clinicians never having previously encountered the term or concept. LBP CPRs were often conceptualised as a formalisation of pattern recognition. Attitudes towards CPRs expressed by study participants were wide-ranging with several facilitating and inhibiting views identified. It was felt that more experienced clinicians had limited need of such tools. Only a small number of participants expressed that they had ever used LBP CPRs in clinical practice. To optimise the successful adoption of an LBP CPR, researchers should consider avoiding the use of the term 'rule' and ensure that the tool and its interface are uncomplicated and easy to use. Understanding potential barriers, the needs of clinicians and the context in which CPRs will be implemented will help facilitate the development of tools with the highest potential to positively influence physiotherapy practice. © 2013 Elsevier Ltd.

Objectives: To examine the validity of clinical tests available for the diagnosis of longstanding groin pain in athletes. Design: Systematic review. Method: A published search strategy of MeSH terms in MEDLINE, CINAHL, EMBASE, and SportDiscuss. Inclusion criteria: diagnostic studies relating to athletic groin pain, professional or semi-professional athletes, symptoms lasting for more than six weeks, and not limited by age or gender. A priori exclusion criteria were utilised. Outcome measures: QUADAS tool, sensitivity and specificity, likelihood ratios and predictive values of the reported tests and investigations. Results: 577 Journal articles were identified. Five studies metall requirements. Sensitivity and specificity of clinical tests ranged between 30 and 100% and 88 and 95% respectively with negative likelihood ratio of 0.15-0.78 and positive likelihood ratios of 1.0-11.0. Sensitivity and specificity of investigations (MRI, herniography, and dynamic ultrasound) ranged between 68% and 100% as well as 33% and 100% respectively with negative likelihood ratios between 0 and 0.32 and positive likelihood ratios between 1.5 and 8.1. Conclusion: There is a lack of validated diagnostic clinical tests available for clinicians and a lack of symptomology being evaluated. It is recommended that a reference standard should be applied and data should be reported in sufficient detail to calculate diagnostic statistics that is useful to the clinician. © 2013 Elsevier Ltd.

Objectives: It is well established that musculoskeletal disorders (MSD) are a significant occupational health issue for dentists and hygienists. Despite this, there has been little advancement in the application of ergonomic principles in the dental profession. While the use of loupes is often promoted as an ergonomic solution, there is little published research to robustly support this claim. The aim of the present study was to investigate the effect of the use of loupes on upper extremity MSD among dental hygienists. Methods: The study was conducted using an exploratory pretest and post-test design, comparing musculoskeletal measures in practising dental hygienists wearing loupes with final-year dental hygiene students who did not wear loupes. Pre- and post-test measures included valid self-reported and objective outcome measures and were measured at baseline and 6 months following the intervention. Statistical analysis was conducted as a series of mixed anovas with time and treatment as the independent variables. Results: The analysis revealed a significant interaction between time and treatment for the Disabilities of the Shoulder, Arm and Hand (DASH) scores (P < 0.04), indicating an improvement in symptoms for the treatment group but a reversed trend for the controls. There was also a significant mean increase in scapular position measures; however, this finding was evident in both groups, indicating that these were not a result of the intervention. Conclusions: Overall, this study suggests that wearing loupes appears to have both positive and negative effects on upper extremity MSD among dental hygienists. Ongoing research is required to determine the long-term effects of loupes wear, over an extended period of time. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

SYNOPSIS: Decision making in physical therapy is increasingly informed by evidence in the form of probabilities. Prior beliefs concerning diagnoses, prognoses, and treatment effects are quantitatively revised by the integration of new information derived from the history, physical examination, and other investigations in a well-recognized application of Bayes' theorem. Clinical prediction rule development studies commonly employ such methodology to produce quantified estimates of the likelihood of patients having certain diagnoses or achieving given outcomes. To date, the physical therapy literature has been limited to the discussion and calculation of the point estimate of such probabilities. The degree of precision associated with the construction of posterior probabilities, which requires consideration of both uncertainty associated with pretest probability and uncertainty associated with test accuracy, remains largely unrecognized and unreported. This paper provides an introduction to the calculation of the uncertainty interval, known as a credible interval, around posterior probability estimates. The method for calculating the credible interval is detailed and illustrated with example data from 2 clinical prediction rule development studies. Two relatively quick and simple methods for approximating the credible interval are also outlined. It is anticipated that knowledge of the credible interval will have practical implications for the incorporation of probabilistic evidence in clinical practice. Consistent with reporting standards for interventional and diagnostic studies, it is equally appropriate that studies reporting posterior probabilities calculate and report the level of precision associated with these point estimates.

Background Shoulder pain and dysfunction can occur following neck dissection surgery for cancer. These conditions often are due to accessory nerve injury. Such an injury leads to trapezius muscle weakness, which, in turn, alters scapular biomechanics. Objective The aim of this study was to assess which strengthening exercises incur the highest dynamic activity of affected trapezius and accessory scapular muscles in patients with accessory nerve dysfunction compared with their unaffected side. Design A comparative design was utilized for this study. Methods The study was conducted in a physical therapy department. Ten participants who had undergone neck dissection surgery for cancer and whose operated side demonstrated clinical signs of accessory nerve injury were recruited. Surface electromyographic activity of the upper trapezius, middle trapezius, rhomboid major, and serratus anterior muscles on the affected side was compared dynamically with that of the unaffected side during 7 scapular strengthening exercises. Results Electromyographic activity of the upper and middle trapezius muscles of the affected side was lower than that of the unaffected side. The neck dissection side affected by surgery demonstrated higher levels of upper and middle trapezius muscle activity during exercises involving overhead movement. The rhomboid and serratus anterior muscles of the affected side demonstrated higher levels of activity compared with the unaffected side. Limitations Exercises were repeated 3 times on one occasion. Muscle activation under conditions of increased exercise dosage should be inferred with caution. Conclusions Overhead exercises are associated with higher levels of trapezius muscle activity in patients with accessory nerve injury following neck dissection surgery. However, pain and correct scapular form must be carefully monitored in this patient group during exercises. Rhomboid and serratus anterior accessory muscles may have a compensatory role, and this role should be considered during rehabilitation. © 2013 American Physical Therapy Association.

Objective The purpose of this exploratory study was to determine if increased vascularity in the rotator interval area of the glenohumeral joint capsule could be visualized with power Doppler ultrasonography (PDUS) in patients with a clinical diagnosis of early-stage adhesive capsulitis. Methods Demographic and clinical characteristics from a consecutive series of 41 patients diagnosed with early-stage adhesive capsulitis were recorded and examination with PDUS was undertaken. Images were reviewed by 3 musculoskeletal radiologists, and consensus was determined on the presence of increased signal in the rotator interval area. Results Consensus was achieved on the presence of increased signal in 12 (29%) of the 41 cases. Participants with an increased PDUS signal did not demonstrate a characteristic set of identifying features, suggesting that those with increased vascularity may not constitute a distinct subgroup. Conclusion This study found that some patients diagnosed with early-stage adhesive capsulitis demonstrated increased vascularity in the rotator interval area when examined with PDUS. These findings suggest that PDUS may have the potential to assist in the identification of increased vascularization in early stages of this disorder. Further research in the use of PDUS in diagnosing early-stage adhesive capsulitis is warranted. © 2013 National University of Health Sciences.
