Objective: To identify the types of clinical prediction rules (CPRs) for low back pain (LBP) that Australian physiotherapists wish to see developed and the characteristics of LBP CPRs that physiotherapists believe are important. Design: Qualitative study using semi-structured focus groups. Setting: Metropolitan and regional areas of New South Wales, Australia. Participants: Twenty-six physiotherapists who manage patients with LBP (77% male, 81% private practice). Results: Participants welcomed the development of prognostic forms of LBP CPRs. Tools that assist in identifying serious spinal pathology, likely responders to interventions, patients who are likely to experience an adverse outcome, and patients not requiring physiotherapy management were also considered useful. Participants thought that LBP CPRs should be uncomplicated, easy to remember, easy to apply, accurate and precise, and well-supported by research evidence. They should not contain an excessive number of variables, use complicated statistics, or contain variables that have no clear logical relationship to the dependent outcome. It was considered by participants that LBP CPRs need to be compatible with traditional clinical reasoning and decision-making processes, and sufficiently inclusive of a broad range of management approaches and common clinical assessment techniques. Conclusion: There were several identified areas of perceived need for LBP CPR development and a range of characteristics such tools need to encompass to be considered clinically meaningful and useful by physiotherapists in this study. Targeting and incorporating the needs and preferences of physiotherapists is likely to result in the development of tools for LBP with the greatest potential to positively impact clinical practice.

Manual therapy is effective for reducing cervicogenic dizziness, a disabling and persistent problem, in the short term. This study investigated the effects of sustained natural apophyseal glides (SNAGs) and passive joint mobilisations (PJMs) on cervicogenic dizziness compared to a placebo at 12 months post-treatment. Eighty-six participants (mean age 62 years, standard deviation (SD) 12.7) with chronic cervicogenic dizziness were randomised to receive SNAGs with self-SNAGs (n=29), PJMs with range-of-motion (ROM) exercises (n=29), or a placebo (n=28) for 2-6 sessions over 6 weeks. Outcome measures were dizziness intensity, dizziness frequency (rated between 0 [none] and 5 [>once/day]), the Dizziness Handicap Inventory (DHI), pain intensity, head repositioning accuracy (HRA), cervical spine ROM, balance, and global perceived effect (GPE). At 12 months both manual therapy groups had less dizziness frequency (mean difference SNAGs vs placebo-0.7, 95% confidence interval (CI)-1.3,-0.2, p=0.01; PJMs vs placebo-0.7,-1.2,-0.1, p=0.02), lower DHI scores (mean difference SNAGs vs placebo-8.9, 95% CI-16.3,-1.6, p=0.02; PJMs vs placebo-13.6,-20.8,-6.4, p<0.001) and higher GPE compared to placebo, whereas there were no between-group differences in dizziness intensity, pain intensity or HRA. There was greater ROM in all six directions for the SNAG group and in four directions for the PJM group compared to placebo, and small improvements in balance for the SNAG group compared to placebo. There were no adverse effects. These results provide evidence that both forms of manual therapy have long-term beneficial effects in the treatment of chronic cervicogenic dizziness.

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.

Objectives: Clinical prediction rules (CPRs) are widely used in medicine, but their application to physiotherapy practice is more recent and less widespread, and their implementation in physiotherapy clinical education has not been investigated. This study aimed to determine the experiences and perceptions of physiotherapy clinical educators regarding CPRs, and whether they are teaching CPRs to students on clinical placement. Design: Cross-sectional observational survey using a modified Dillman method. Participants: Clinical educators (n = 211, response rate 81%) supervising physiotherapy students from 10 universities across 5 states and territories in Australia. Results: Half (48%) of respondents had never heard of CPRs, and a further 25% had never used CPRs. Only 27% reported using CPRs, and of these half (51%) were rarely if ever teaching CPRs to students in the clinical setting. However most respondents (81%) believed CPRs assisted in the development of clinical reasoning skills and few (9%) were opposed to teaching CPRs to students. Users of CPRs were more likely to be male (p <. 0.001), have post-professional qualifications (p = 0.020), work in private practice (p <. 0.001), and work in the area of musculoskeletal physiotherapy (p <. 0.001) compared with non-users. The CPRs most commonly known, used and taught were the Ottawa Ankle Rule, the Ottawa Knee Rule, and Wells' Rule for Deep Vein Thrombosis. Conclusions: Students are unlikely to be learning about CPRs on clinical placement, as few clinical educators use them. Clinical educators will require training in CPRs and assistance in teaching them if students are to better learn about implementing CPRs in physiotherapy clinical practice.

Introduction: Cervical spine manual therapy has been associated with a small risk of serious adverse neurovascular events, particularly to the vertebral arteries. Sustained end-range rotation is recommended clinically as a pre-manipulative screening tool; however ultrasound studies have yielded conflicting results about the effect of rotation on blood flow in the vertebral arteries. There has been little research on internal carotid arterial flow or utilising the reference standard of angiography. Objectives: To evaluate the mean effect of cervical rotation on blood flow in the craniocervical arteries and blood supply to the brain, as well as individual variation. Design: This was an observational study. Method: Magnetic resonance angiography was used to measure average blood flow volume in the vertebral arteries, internal carotid arteries, and total cerebral inflow, in three neck positions: neutral, end-range left rotation and end-range right rotation in healthy adults. Results: Twenty participants were evaluated. There was a decrease in average blood flow volume in the vertebral and internal carotid arteries on contralateral rotation, compared to neutral. This was statistically significant on left rotation only. Ipsilateral rotation had no effect on average blood flow volume in any artery. Total cerebral inflow was not significantly affected by rotation in either direction. Conclusions: It appears that in healthy adults the cerebral vasculature can compensate for decreased flow in one or more arteries by increasing flow in other arteries, to maintain cerebral perfusion. Sustained end-range rotation may therefore reflect the compensatory capacity of the system as a whole rather than isolated vertebrobasilar function.

BACKGROUND: There is little health specific literature on returning nurses with injuries to work despite the high incidence of injuries and the workforce shortages of these professionals. OBJECTIVE: To identify enabling factors and barriers to return-to-work for nurses with injuries from the perspective of return-to-work coordinators. PARTICIPANTS: Workplace return-to-workcoordinators employed in a health or disability facility who had worked on a rehabilitation case with a nurse with injuries in the past 12 months in New South Wales (NSW), Australia. METHOD: Five focus groups were conducted with 25 return-to-work coordinators from 14 different organisations, representing different health sectors (aged, disability, public and private hospital and community health) in metropolitan and rural areas of NSW, Australia. RESULTS: This study reports findings specifically relating to the provision of suitable duties for nurses with injuries. Four key themes were identified: suitable duties; supernumerary positions; nurse specialisation and tailoring of return-to-work plans. CONCLUSIONS: This study identified that return-to-work coordinators were resourceful and innovative in their approach to the provision of suitable duties for nurses with injuries and highlighted the importance of including clinical duties in any return-to-work program and of tailoring the return-to-work to the nurses' work and personal circumstances.

Objective To evaluate and compare the effects of 2 manual therapy interventions on cervical spine range of motion (ROM), head repositioning accuracy, and balance in patients with chronic cervicogenic dizziness. Design Randomized controlled trial with 12-week follow-up using blinded outcome assessment. Setting University School of Health Sciences. Participants Participants (N=86; mean age Â± SD, 62.0Â±12.7y; 50% women) with chronic cervicogenic dizziness. Interventions Participants were randomly assigned to 1 of 3 groups: sustained natural apophyseal glides (SNAGs) with self-SNAG exercises, passive joint mobilization (PJM) with ROM exercises, or a placebo. Participants each received 2 to 6 treatments over 6 weeks. Main Outcome Measures Cervical ROM, head repositioning accuracy, and balance. Results SNAG therapy resulted in improved (P=.05) cervical spine ROM in all 6 physiological cervical spine movement directions immediately posttreatment and at 12 weeks. Treatment with PJM resulted in improvement in 1 of the 6 cervical movement directions posttreatment and 1 movement direction at 12 weeks. There was a greater improvement (P<.01) after SNAGs than PJM in extension (mean difference, -7.5Â°; 95% confidence interval [CI], -13Â° to -2.0Â°) and right rotation (mean difference, -6.8Â°; 95% CI, -11.5Â° to -2.1=) posttreatment. Manual therapy had no effect on balance or head repositioning accuracy. Conclusions SNAG treatment improved cervical ROM, and the effects were maintained for 12 weeks after treatment. PJM had very limited impact on cervical ROM. There was no conclusive effect of SNAGs or PJMs on joint repositioning accuracy or balance in people with cervicogenic dizziness.

Background There is short-term evidence for treatment of cervicogenic dizziness with Mulligan sustained natural apophyseal glides (SNAGs) but no evidence for treatment with Maitland mobilizations. Objective The purpose of this study was to compare the effectiveness of SNAGs and Maitland mobilizations for cervicogenic dizziness. Design A double-blind, parallel-arm randomized controlled trial was conducted. Setting The study was conducted at a university in Newcastle, Australia. Participants Eighty-six people with cervicogenic dizziness were the study participants. Interventions Included participants were randomly allocated to receive 1 of 3 interventions: Mulligan SNAGs (including self-administered SNAGs), Maitland mobilizations plus range-of-motion exercises, or placebo. Measurements The primary outcome measure was intensity of dizziness. Other outcome measures were: frequency of dizziness, the Dizziness Handicap Inventory (DHI), intensity of pain, and global perceived effect (GPE). Results Both manual therapy groups had reduced dizziness intensity and frequency posttreatment and at 12 weeks compared with baseline. There was no change in the placebo group. Both manual therapy groups had less dizziness intensity posttreatment (SNAGs: mean difference=-20.7, 95% confidence interval [95% CI]=-33.6, -7.7; mobilizations: mean difference=-15.2, 95% CI=-27.9, -2.4) and at 12 weeks (SNAGs: mean difference=-18.4, 95% CI=-31.3, -5.4; mobilizations: mean difference=-14.4, 95% CI=-27.4, -1.5) compared with the placebo group. Compared with the placebo group, both the SNAG and Maitland mobilization groups had less frequency of dizziness at 12 weeks. There were no differences between the 2 manual therapy interventions for these dizziness measures. For DHI and pain, all 3 groups improved posttreatment and at 12 weeks. Both manual therapy groups reported a higher GPE compared with the placebo group. There were no treatment-related adverse effects lasting longer than 24 hours. Limitations The therapist performing the interventions was not blind to group allocation. Conclusions Both SNAGs and Maitland mobilizations provide comparable immediate and sustained (12 weeks) reductions in intensity and frequency of chronic cervicogenic dizziness.

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. Â© 2014 American Physical Therapy Association.

Background: Clinicians commonly assess cervical range of motion (ROM), but it has rarely been critically evaluated for its ability to contribute to patient diagnosis or prognosis, or whether it is affected by mobilisation/manipulation. Objectives: This review summarises the methods used to measure cervical ROM in research involving patients with cervical spine disorders, reviews the evidence for using cervical ROM in patient diagnosis, prognosis, and evaluation of the effects of mobilisation/manipulation on cervical ROM. Data sources and study selection: A systematic search of MEDLINE, EMBASE, CINAHL, AMED and ICL databases was conducted, addressing one of four constructs related to cervical ROM: measurement, diagnosis, prognosis, and the effects of mobilisation/manipulation on cervical ROM. Study appraisal and synthesis: Two independent raters appraised methodological quality using the QUADAS-2 tool for diagnostic studies, the QUIPS tool for prognostic studies and the PEDro scale for interventional studies. Heterogeneity of studies prevented meta-analysis. Results: Thirty-six studies met the criteria and findings showed there is limited evidence for the diagnostic value of cervical ROM in cervicogenic headache, cervical radiculopathy and cervical spine injury. There is conflicting evidence for the prognostic value of cervical ROM, though restricted ROM appears associated with negative outcomes while greater ROM is associated with positive outcomes. There is conflicting evidence as to whether cervical ROM increases or decreases following mobilisation/manipulation. Conclusion and implications of key findings: Cervical ROM has value as one component of assessment, but clinicians should be cautious about making clinical judgments primarily on the basis of cervical ROM.

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.

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.

Evidence is emerging for central nervous system (CNS) changes in the presence of musculoskeletal dysfunction and pain. Motor control exercises, and potentially manual therapy, can induce changes in the CNS, yet the focus in musculoskeletal physiotherapy practice is conventionally on movement impairments with less consideration of intervention-induced neuroplastic changes. Studies in healthy individuals and those with neurological dysfunction provide examples of strategies that may also be used to enhance neuroplasticity during the rehabilitation of individuals with musculoskeletal dysfunction, improving the effectiveness of interventions. In this paper, the evidence for neuroplastic changes in patients with musculoskeletal conditions is discussed. The authors compare and contrast neurological and musculoskeletal physiotherapy clinical paradigms in the context of the motor learning principles of experience-dependent plasticity: part and whole practice, repetition, task-specificity and feedback that induces an external focus of attention in the learner. It is proposed that increased collaboration between neurological and musculoskeletal physiotherapists and researchers will facilitate new discoveries on the neurophysiological mechanisms underpinning sensorimotor changes in patients with musculoskeletal dysfunction. This may lead to greater integration of strategies to enhance neuroplasticity in patients treated in musculoskeletal physiotherapy practice.
|2014||Farrell SF, Osmotherly PG, Rivett DA, Cornwall J, 'Formic acid demineralization does not affect the morphometry of cervical zygapophyseal joint meniscoids', Anatomical Science International, (2014)|
Demineralization can facilitate the dissection of soft tissue structures in inaccessible locations by softening surrounding bone so that it can be easily removed without risking damage to the structure of interest. However, it is unclear whether demineralization alters the morphometry of soft tissues if used for this purpose. We have therefore examined the effect of extended-immersion formic acid demineralization on the size and shape of cervical zygapophyseal joint meniscoids to evaluate its usefulness as a means of facilitating dissection and examination of soft tissue structures from bony regions. Four cadaveric cervical spines were dissected, and three randomly selected zygapophyseal joints from each spine (12 in total) were removed, disarticulated and immersed in 5 % formic acid for 32 days. Each joint was examined using a surgical microscope and photographed, and meniscoid length and surface area measured at days 0, 4, 18, and 32. Measurements were made on magnified digital photographs, and each measurement was repeated three times to determine intra-rater reliability. Data were analyzed using repeated-measures analysis of variance. Significance was set at p < 0.05. There were no significant differences between any of the measures over time for all of the variables assessed (F = 0.302-1.576, p = 0.226-0.759, partial Â¿2 = 0.029-0.136). For all measurements, intra-rater reliability was high (intra-class correlation > 0.9). These results support the use of formic acid demineralization to facilitate the study of cervical spine meniscoids by dissection, as even after a period of extended immersion in the solution, the morphometry of the structures was not significantly altered. Findings may have implications for dissection studies of other meniscoid-like soft tissue structures that use formic acid demineralization. Â© 2014 Japanese Association of Anatomists.

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.

A consensus clinical reasoning framework for best practice for the examination of the cervical spine region has been developed through an iterative consultative process with experts and manual physical therapy organisations. The framework was approved by the 22 member countries of the International Federation of Orthopaedic Manipulative Physical Therapists (October 2012). The purpose of the framework is to provide guidance to clinicians for the assessment of the cervical region for potential of Cervical Arterial Dysfunction in advance of planned management (inclusive of manual therapy and exercise interventions). The best, most recent scientific evidence is combined with international expert opinion, and is presented with the intention to be informative, but not prescriptive; and therefore as an aid to the clinician's clinical reasoning. Important underlying principles of the framework are that 1] although presentations and adverse events of Cervical Arterial Dysfunction are rare, it is a potentially serious condition and needs to be considered in musculoskeletal assessment; 2] manual therapists cannot rely on the results of one clinical test to draw conclusions as to the presence or risk of Cervical Arterial Dysfunction; and 3] a clinically reasoned understanding of the patient's presentation, including a risk:benefit analysis, following an informed, planned and individualised assessment, is essential for recognition of this condition and for safe manual therapy practice in the cervical region. Clinicians should also be cognisant of jurisdictionally specific requirements and obligations, particularly related to patient informed consent, when intending to use manual therapy in the cervical region.

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. Â© 2013 National University of Health Sciences.
