Published 2018. This article is a U.S. Government work and is in the public domain in the USA Background: Recent clinical practice guidelines have suggested conservative treatment approaches, including physical therapy, are indicated as first-line treatment for patients with low back pain (LBP); however, LBP continues to be managed with opioids, despite decreases in function, morbidity, and insignificant improvements in pain. Objective: The primary purpose was to compare characteristics and downstream medication use between patients with LBP with prior opioid exposure vs. those who were opioid-naïve. The secondary purpose was to explore the role of prior opioid use by LBP disability. Methods: Seven hundred and nine participants in a LBP self-management class were evaluated utilizing self-report data at baseline and longitudinal claims data from the Military Health System Data Repository. Participants were dichotomized into opioid-naïve and prior opioid use groups and then further divided into low and high disability groups based on Oswestry Disability Index (ODI) scores. Patient characteristics, comorbidities, and medication use were compared between groups. Results: Prior opioid users had significantly higher baseline ODI and Fear Avoidance Beliefs Questionnaire physical activity subscale and work subscale scores as well as pre-index instances of mental health disorders, chronic pain, and insomnia than opioid-naïve individuals. Prior opioid users filled significantly more pain medication prescriptions in the year after the index date than did opioid-naïve individuals. Prior opioid users were significantly more likely to be taking opioids at 1¿year after the index date, regardless of disability level. Conclusion: In patients presenting with LBP, prior opioid exposure appears to be related to increased analgesic use (opioid and non-opioid) and longitudinal analgesic utilization at 1¿year after the index date.

Stepped care approaches are emphasized in guidelines for musculoskeletal pain, recommending less invasive or risky evidence-based intervention, such as manual therapy (MT), before more aggressive interventions such as opioid prescriptions. The order and timing of care can alter recovery trajectories. Objective. To compare one-year downstream health care utilization in patients with spine or shoulder disorders who received only MT vs MT and opioids. The secondary aim was to compare differences based on order and timing of opioids and MT. Design. Retrospective observational cohort. Methods. Patients with an initial consultation for a spine or shoulder disorder who received at least one visit for MT were included. Person-level data from the Military Health System Management and Reporting Tool (M2) database were aggregated by a senior health care analyst at Madigan Army Medical Center. Groups were created based on the order and timing of interventions provided. Outcomes included health care utilization (medical costs and visits) over the year following initial consultation. Control measures included metabolic, mental health, chronic pain, sleep, and substance abuse comorbidities, as well as prior opioid prescriptions. Generalized linear models with gamma log links were run due to the heavily skewed nature of cost data. Results. From 1,876 unique patients with spine or shoulder disorders receiving MT, 1,162 (61.9%) also received prescription opioids. Mean one-year costs in the MT-only group ($5,410, 95% confidence interval [CI] ¼ $5,109 to $5,730) were significantly lower than in the MTþopioid group ($10,498, 95% CI ¼ $10,043 to $10,973). When patients had both treatments, mean one-year costs in the MT-first ($10,782, 95% CI ¼ $10,050 to $11,567) were significantly lower (P ¼ 0.030) than opioid-first ($11,938, 95% CI ¼ $11,272 to $12,643), and MT-first had a significantly lower mean days¿ supply of opioids (34.2 vs 70.9, P < 0.001) and mean number of unique opioid prescriptions (3.1 vs 6.5, P < 0.001). Conclusions. MT alone resulted in lower downstream costs than with opioid prescriptions. Both the order of treatment (MT before opioid prescriptions) and the timing of treatment (MT < 30 days) resulted in a significant reduction of resources (costs, visits, and opioid utilization) in the year after initial consultation. Clinicians should consider the implications of first-choice decisions and the timing of care for treatment choices utilized for patients with spine and shoulder disorders.

Published 2019. This article is a U.S. Government work and is in the public domain in the USA Purpose: The aims of the present study were: (a) to identify the incidence of osteoarthritis (OA) after a traumatic knee injury; (b) identify the risk of post-traumatic osteoarthritis (PTOA) based on the type of injury; and (c) identify the time from injury to OA diagnosis. Patients and methods: The Expeditionary Medical Encounter Database, containing healthcare utilization for all deployment injuries sustained by military service members, was queried for traumatic knee injuries between 2001 and 2016. Subsequent diagnosis of knee OA was identified, defined as PTOA. Time to knee PTOA diagnosis was determined and logistic regression was used to obtain odds ratios (ORs) (95% confidence interval [CI]) between knee injury type and development of PTOA. Results: A total of 345 (9.57%) of the 3,605 subjects were diagnosed with PTOA. The median time to diagnosis was 4.10¿years. Four primary diagnoses remained significantly associated with PTOA after adjusting for age and injury severity score: fracture (adjusted OR [aOR]¿=¿1.36; 95% CI 1.02, 1.82), sprain (aOR¿=¿1.59; 95% CI 1.23, 2.06), dislocation (aOR¿=¿3.70; 95% CI 2.09, 6.55) and derangement (aOR¿=¿2.38; 95% CI 1.33, 4.28). Subjects were significantly less likely to develop PTOA after a soft-tissue injury (aOR¿=¿0.44; 95% CI 0.41, 0.75). Conclusions: A substantial number of individuals with a traumatic knee injury developed early PTOA (9.6%). Certain knee injuries have a greater association with PTOA. Future studies should implement longer surveillance periods and identify other healthcare variables associated with the risk of developing PTOA, to include appropriate and timely interventions.

© 2019 Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States. Low back pain (LBP) is a common condition suffered by military personnel. Psychosocial factors play a role in LBP prognosis and can be addressed with self-management tools. This study's purpose was to (1) describe clinical changes in psychosocial factors of LBP following a self-management intervention and (2) explore the LBP experience of military trainees. Ten participants in Initial Entry Training (IET) were included in this mixed methods study. A self-management intervention of exercises and psychosocial education was provided. Quantitative instruments assessing psychosocial factors were delivered at baseline and 6 weeks. Qualitative data were gathered after treatment and analyzed using a phenomenological approach. Low levels of psychosocial risk factors were reported. Patient satisfaction (COPM-Satisfaction subscale) was the only outcome that achieved statistical significance at 6 weeks (p = 0.037). Three themes emerged from the qualitative results: The influence of the military culture on recovery from LBP, the LBP experience of a trainee, and promoting the self-management of LBP. While this cohort of IET soldiers exhibited low levels of psychosocial risk factors, qualitative reports indicate that LBP has a negative impact on participation in training, academics, and interpersonal relationships. The constraints of military training make seeking care and applying treatment strategies challenging.

BACKGROUND: Therapeutic exercise is commonly used to treat individuals with knee disorders, but dosing parameters for optimal outcomes are unclear. Large variations exist in exercise prescription, and research related to specific dosing variables for knee osteoarthritis, patellar tendinopathy, and patellofemoral pain is sparse. OBJECTIVES: To identify specific doses of exercise related to improved outcomes of pain and function in individuals with common knee disorders, categorized by effect size. METHODS: Five electronic databases were searched for studies related to exercise and the 3 diagnoses. Means and standard deviations were used to calculate effect sizes for the exercise groups. The overall quality of evidence was assessed using the Physiotherapy Evidence Database scale. RESULTS: Five hundred eighty-three studies were found after the initial search, and 45 were included for analysis after screening. Physiotherapy Evidence Database scale scores were "fair" quality and ranged from 3 to 8. For knee osteoarthritis, 24 total therapeutic exercise sessions and 8- and 12-week durations of exercise were parameters most often associated with large effects. An exercise frequency of once per week was associated with no effect. No trends were seen with exercise dosing for patellar tendinopathy and patellofemoral pain. CONCLUSION: This review suggests that there are clinically relevant exercise dosing variables that result in improved pain and function for patients with knee osteoarthritis, but optimal dosing is still unclear for patellar tendinopathy and patellofemoral pain. Prospective studies investigating dosing parameters are needed to confirm the results from this systematic review.

Methods: AMED, EMBASE and MEDLINE were searched from 2005 to August 2017 for randomized controlled trials related to exercise for these three diagnoses. The Physiotherapy Evidence Database scale was used for methodological quality assessment. Exercise dosing variables and outcome measures related to pain and function were extracted from the studies, and standardized mean differences were calculated for the exercise groups. Results: Fourteen studies met the final inclusion. A majority of the studies showed large effects and two small trends were identified. Patients with plantar heel pain may benefit more from a daily home exercise program than two supervised visits per week (SMD = 3.82), but this recommendation is based on weak evidence. In achilles tendinopathy, a relationship was also seen when sets and repetitions of eccentric exercise were performed as tolerated (SMD = 1.08 for function, -1.29 for pain). Conclusions: Session duration, frequency, total number of visits, and overall length of care may all be dosing variables with limited value for determining effective exercise prescription. However, the limited number of studies prevents any definitive conclusions. Further investigation is warranted to improve our understanding of the influence exercise dosing has on treatment effect sizes. Future randomized controlled trials comparing specific exercise dose variables should be conducted to clarify the impact of these variables.

© 2018 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia Background: Trigger point dry needling interventions are utilized by physical therapists to manage shoulder pain. Observational studies have shown positive short-term outcomes in patients with subacromial pain syndrome receiving trigger point dry needling. However, little research has been done to evaluate the long-term effectiveness of trigger point dry needling specifically as it compares to other commonly utilized interventions such as exercise and manual therapy. The purpose of this study is to assess the additive short and long-term effectiveness of trigger point dry needling to a standard physical therapy approach of manual therapy and exercise for patients with subacromial pain syndrome. Methods: This multicenter randomized trial with 3 arms was designed following the standard protocol items for randomized interventional trials. Results will be reported consistent with the consolidated standards of reporting trials guidelines. 130 participants will be randomized to receive standard PT interventions alone (manual therapy and exercise), standard PT and trigger point dry needling or standard PT and sham trigger point dry needling. The primary outcome measures will be the Shoulder Pain and Disability Index and Patient Reported Outcomes Measurement Information Systems (PROMIS-57) scores collected at baseline, 6-weeks, 6-months and one year. Healthcare utilization will be collected for 12 months following enrollment and groups analyzed for differences. Discussion: It is not known if trigger point dry needling provides long-term benefit for individuals with subacromial pain syndrome. This study will help determine if this intervention provides additive benefits over those observed with the commonly applied interventions of exercise and manual therapy.

© 2015, The Association of Bone and Joint Surgeons®. Background: Musculoskeletal injury is the most common reason that soldiers are medically not ready to deploy. Understanding intrinsic risk factors that may place an elite soldier at risk of musculoskeletal injury may be beneficial in preventing musculoskeletal injury and maintaining operational military readiness. Findings from this population may also be useful as hypothesis-generating work for particular civilian settings such as law enforcement officers (SWAT teams), firefighters (smoke jumpers), or others in physically demanding professions. Questions/purposes: The purposes of this study were (1) to examine whether using baseline measures of self-report and physical performance can identify musculoskeletal injury risk; and (2) to determine whether a combination of predictors would enhance the accuracy for determining future musculoskeletal injury risk in US Army Rangers. Methods: Our study was a planned secondary analysis from a prospective cohort examining how baseline factors predict musculoskeletal injury. Baseline predictors associated with musculoskeletal injury were collected using surveys and physical performance measures. Survey data included demographic variables, injury history, and biopsychosocial questions. Physical performance measures included ankle dorsiflexion, Functional Movement Screen, lower and upper quarter Y-balance test, hop testing, pain provocation, and the Army Physical Fitness Test (consisting of a 2-mile run and 2 minutes of sit-ups and push-ups). A total of 320 Rangers were invited to enroll and 211 participated (66%). Occurrence of musculoskeletal injury was tracked for 1¿year using monthly injury surveillance surveys, medical record reviews, and a query of the Department of Defense healthcare utilization database. Injury surveillance data were available on 100% of the subjects. Receiver operator characteristic curves and accuracy statistics were calculated to identify predictors of interest. A logistic regression equation was then calculated to find the most pertinent set of predictors. Of the 188 Rangers (age, 23.3 ± 3.7¿years; body mass index, 26.0 ± 2.4¿kg/m 2 ) remaining in the cohort, 85 (45.2%) sustained a musculoskeletal injury of interest. Results: Smoking, prior surgery, recurrent prior musculoskeletal injury, limited-duty days in the prior year for musculoskeletal injury, asymmetrical ankle dorsiflexion, pain with Functional Movement Screen clearing tests, and decreased performance on the 2-mile run and 2-minute sit-up test were associated with increased injury risk. Presenting with one or fewer predictors resulted in a sensitivity of 0.90 (95% confidence interval [CI], 0.83¿0.95), and having three or more predictors resulted in a specificity of 0.98 (95% CI, 0.93¿0.99). The combined factors that contribute to the final multivariable logistic regression equation yielded an odds ratio of 4.3 (95% CI, 2.0¿9.2), relative risk of 1.9 (95% CI, 1.4¿2.6), and an area under the curve of 0.64. Conclusions: Multiple factors (musculoskeletal injury history, smoking, pain provocation, movement tests, and lower scores on physical performance measures) were associated with individuals at risk for musculoskeletal injury. The summation of the number of risk factors produced a highly sensitive (one or less factor) and specific (three or more factors) model that could potentially be used to effectively identify and intervene in those persons with elevated risk for musculoskeletal injury. Future research should establish if screening and intervening can improve musculoskeletal health and if our findings among US Army Rangers translate to other occupations or athletes. Level of Evidence: Level II, prognostic study.

Background: Corticosteroid injections (CSIs) and physical therapy are used to treat patients with the shoulder impingement syndrome (SIS) but have never been directly compared. Objective: To compare the effectiveness of 2 common nonsurgical treatments for SIS. Design: Randomized, single-blind, comparative-effectiveness, parallel-group trial. (ClinicalTrials.gov: NCT01190891) Setting: Military hospital-based outpatient clinic in the United States. Patients: 104 patients aged 18 to 65 years with unilateral SIS between June 2010 and March 2012. Intervention: Random assignment into 2 groups: 40-mg triamcinolone acetonide subacromial CSI versus 6 sessions of manual physical therapy. Measurements: The primary outcome was change in Shoulder Pain and Disability Index scores at 1 year. Secondary outcomes included the Global Rating of Change scores, the Numeric Pain Rating Scale scores, and 1-year health care use. Results: Both groups demonstrated approximately 50% improvement in Shoulder Pain and Disability Index scores maintained through 1 year; however, the mean difference between groups was not significant (1.5% [95% CI, -6.3% to 9.4%]). Both groups showed improvements in Global Rating of Change scale and pain rating scores, but between-group differences in scores for the Global Rating of Change scale (0 [CI, -2 to 1]) and pain rating (0.4 [CI, -0.5 to 1.2]) were not significant. During the 1-year follow-up, patients receiving CSI had more SIS-related visits to their primary care provider (60% vs. 37%) and required additional steroid injections (38% vs. 20%), and 19% needed physical therapy. Transient pain from the CSI was the only adverse event reported. Limitation: The study occurred at 1 center with patients referred to physical therapy. Conclusion: Both groups experienced significant improvement. The manual physical therapy group used less 1-year SIS-related health care resources than the CSI group.

Background and Purpose. Physical therapists frequently make important point-of-care decisions for musculoskeletal injuries and conditions. In the Military Health System (MHS), these decisions may occur while therapists are deployed in support of combat troops, as well as in a more traditional hospital setting. Proficiency with the musculoskeletal examination, including a fundamental understanding of the diagnostic role of musculoskeletal imaging, is an important competency for physical therapists. The purpose of this article is to present 3 cases managed by physical therapists in unique MHS settings, highlighting relevant challenges and clinical decision making. Case Description. Three cases are presented involving conditions where the physical therapist was significantly involved in the diagnosis and clinical management plan. The physical therapist's clinical privileges, including the ability to order appropriate musculoskeletal imaging procedures, were helpful in making clinical decisions that facilitate timely management. The cases involve patients with an ankle sprain and Maisonneuve fracture, a radial head fracture, and a pelvic neoplasm referred through medical channels as knee pain. Outcomes. Clinical pathways from point of care are discussed, as well as the reasoning that led to decisions affecting definitive care for each of these patients. In each case, emergent treatment and important combat evacuation decisions were based on a combination of examination and management decisions. Discussion. Physical therapists can provide important contributions to the primary management of patients with musculoskeletal conditions in a variety of settings within the MHS. In the cases described, advanced clinical privileges contributed to the success in this role. © 2013 American Physical Therapy Association.
