A Physical Therapist Experience, Observation, and Practice With an Infantry Brigade Combat Team in Support of Operation Iraqi Freedom

BACKGROUND In 2005 the first physical therapists were employed in direct support of infantry brigade combat teams (BCTs) during a combat deployment. The initiative sought to bring soldiers direct access to specialized musculoskeletal care at the places they work and live. The goal was to prevent deferment of care for injuries that may become chronic and to decrease medical evacuations for orthopedic nonbattle injuries by locally providing acute and definitive management. PURPOSE To describe the experience of a newly authorized physical therapy role in direct support of an infantry BCT in Iraq during Operation Iraqi Freedom (OIF). The practice patterns, observation, and utilization of the physical therapy team are reported, to include demographics, injury prevalence, and outcomes. DISCUSSION Physical therapists should be part of the risk management team and advise unit commanders on injury-prevention strategies in a combat setting.

A manual physical therapy approach versus subacromial corticosteroid injection for treatment of shoulder impingement syndrome: a protocol for a randomised clinical trial

Introduction Corticosteroid injections (CSI) are a recommended and often-used first-line intervention for shoulder impingement syndrome (SIS) in primary care and orthopaedic settings. Manual physical therapy (MPT) offers a non-invasive approach with negligible risk for managing SIS. There is limited evidence to suggest significant long-term improvements in pain, strength and disability with the use of MPT, and there are conflicting reports from systematic reviews that question the long-term efficacy of CSI. Specifically, the primary objective is to compare the effect of CSI and MPT on pain and disability in subjects with SIS at 12 months. Design This pragmatic randomised clinical trial will be a mixed-model 2×5 factorial design. The independent variables are treatment (MPT and CSI) and time with five levels from baseline to 1 year. The primary dependent variable is the Shoulder Pain and Disability Index, and the secondary outcome measures are the Global Rating of Change and the Numeric Pain Rating Scale. For each ANOVA, the hypothesis of interest will be the two-way group-by-time interaction. Methods and analysis The authors plan to recruit 104 participants meeting established impingement criteria. Following examination and enrolment, eligible participants will be randomly allocated to receive a pragmatic approach of either CSI or MPT. The MPT intervention will consist of six sessions, and the CSI intervention will consist of one to three sessions. All subjects will continue to receive usual care. Subjects will be followed for 12 months. Dissemination and ethics The protocol was approved by the Madigan Army Medical Center Institutional Review Board. The results may have an impact on clinical practice guidelines. This study was funded in part by the Orthopaedic Physical Therapy Products Grant through the American Academy of Orthopaedic Manual Physical Therapists.

Clinician Perception of the Impact of Deployed Physical Therapists as Physician Extenders in a Combat Environment

UNLABELLED Physical therapists (PTs) serve as physician extenders performing direct access evaluations for musculoskeletal conditions. The previous war-time mission of PTs was limited to level III medical care. Recently PTs began providing care at levels I/II with brigade combat teams (BCTs). PURPOSE Determine the sentiment of battlefield providers at levels I/II regarding the operational impact of PTs. METHODS Surveys were provided to BCT medical providers. RESULTS There were 107 responses (response rate of 51%). According to the responses, PTs made a significant impact on overall mission accomplishment (97%) and patient prognosis (83%) and were considered local experts in musculoskeletal pathology (92%), including the ordering of radiographs (79%). Their presence was thought to significantly decrease medical evacuations within theater (68%) and out of theater (73%). CONCLUSION There was a positive sentiment toward PTs in the BCT, suggesting they are highly valued. Future studies need to clarify further operational, medical, and fiscal implications.

Re: Zhang W, Moskowitz RW, Nuki G, et al. OARSI recommendations for the management of hip and knee osteoarthritis, Part II: OARSI evidence-based, expert consensus guidelines. Osteoarthritis Cartilage 2008;16:137-62.

The recent expert-consensus guidelines for the management of knee and hip osteoarthritis (OA) are very insightful and should serve as a powerful clinical tool for many providers 1 . Although minimal attention is given to the positive effects of manual physical therapy despite strong randomized control trials (RCT) in the literature 2,3 , the fact that the panel unanimously recommends evaluation and referral to a physical therapist is promising. These RCT’s evaluating manual physical therapy were included in the OsteoArthritis Research Society International (OARSI) panel’s literature review, however the emphasis of the actual recommendation appears to be focused more on the provision of assisted devices for ambulation, although none of the RCT’s referenced in that section include that as a studied intervention. As in many other disciplines, the specific intervention provided by a clinician can vary. When evaluating the efficacy of these interventions it is important for the medical provider to distinguish between current practice and best evidence-based practice when interpreting the results published in the literature. In this case, recommendations would be better served based on specific evidence-validated interventions provided by physical therapists. In addition, the statement that no RCT’s for management of hip OA by a physical therapist exist might imply a lack of thoroughness in the literature review for this portion. In a 2004 RCT in Arthritis and Rheumatism by Hoeksma et al., a 5-week manual therapy program was shown to be significantly superior to exercise therapy not only in general perceived improvement, but also in pain, hip function, walking speed, range of motion, and quality of life 4 .

Risk Factors for Low Back Pain and Spine Surgery

INTRODUCTION Musculoskeletal low back pain (LBP) is commonly treated symptomatically, with practice guidelines advocating reserving surgery for cases that fail conservative care. This study examined medical comorbidities and demographic variables as risk factors for chronic/recurrent LBP, spinal surgery, and time to surgery. METHODS A 2015 retrospective cohort study was conducted in U.S. Army soldiers (N=1,092,420) from 2002 to 2011. Soldiers with medical encounters for LBP were identified using ICD-9 codes. Surgical treatment for LBP was identified according to Current Procedural Terminology codes. Comorbid medical conditions (psychological disorders, sleep disorders, tobacco use, alcohol use, obesity) and demographic variables were examined as risk factors for chronic/recurrent LBP within 1 year of the incident encounter, surgery for LBP, and time to surgery. RESULTS Of 383,586 patients with incident LBP, 104,169 (27%) were treated for chronic/recurrent LBP and 7,446 (1.9%) had surgery. Comorbid variables showed increased risk of chronic/recurrent LBP ranging from 26% to 52%. Tobacco use increased risk for surgery by 33% (risk ratio, 1.33; 95% CI=1.24, 1.44). Comorbid variables showed 10%-42% shorter time to surgery (psychological disorders, time ratio [TR]=0.90, 95% CI=0.83, 0.98; sleep disorders, TR=0.68, 95% CI=0.60, 0.78; obesity, TR=0.88, 95% CI=0.79, 0.98; tobacco use, TR=0.58, 95% CI=0.54, 0.63; alcohol use, TR=0.85, 95% CI=0.70, 1.05). Women showed 20% increased risk of chronic/recurrent LBP than men but 42% less risk of surgery. CONCLUSIONS In the presence of comorbidities associated with mental health, sleep, obesity, tobacco use, and alcohol use, LBP shows increased risk of becoming chronic/recurrent and faster time to surgery.

Clinical Reasoning and Advanced Practice Privileges Enable Physical Therapist Point-of-Care Decisions in the Military Health Care System: 3 Clinical Cases

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 therapists 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.

Differential Diagnosis and Management of Ankylosing Spondylitis Masked as Adhesive Capsulitis: A Resident's Case Problem

STUDY DESIGN Residents case problem. BACKGROUND Ankylosing spondylitis is a potentially debilitating seronegative spondyloarthropathy, with inflammatory low back pain as the most commonly reported symptom. In the absence of low back pain, identification of other diagnostic criteria or associated impairments and joint involvement, such as involvement of the hip or shoulder, may be beneficial. DIAGNOSIS A 32-year-old man with right shoulder pain and decreased range of motion was referred with a diagnosis of adhesive capsulitis. He had been managed by multiple healthcare providers for 3 years before being referred to a physical therapist. Glenoid labral pathology was evident on prior magnetic resonance imaging, which had led to a persistent focus on the shoulder. The evaluation by the physical therapist revealed significant mobility deficits in the cervical, thoracic, and lumbar spine. Radiographs and laboratory tests were ordered and a referral was made to rheumatology after the initial physical therapy assessment. The diagnostic work-up confirmed the diagnosis of ankylosing spondylitis and led to multidisciplinary management of the disease. DISCUSSION Low back pain is often the primary symptom of ankylosing spondylitis later in the disease process. Earlier indicators of ankylosing spondylitis, such as severely impaired mobility and spine stiffness, may help guide detection in the absence of spinal pain. In this case, an appropriate diagnosis led to improvement in the management strategy of what might have appeared to be unrelated shoulder pain. Early differential diagnosis is important, as emerging interventions show promise when used earlier in the disease process.

Leveraging healthcare utilization to explore outcomes from musculoskeletal disorders: methodology for defining relevant variables from a health services data repository

BackgroundLarge healthcare databases, with their ability to collect many variables from daily medical practice, greatly enable health services research. These longitudinal databases provide large cohorts and longitudinal time frames, allowing for highly pragmatic assessment of healthcare delivery. The purpose of this paper is to discuss the methodology related to the use of the United States Military Health System Data Repository (MDR) for longitudinal assessment of musculoskeletal clinical outcomes, as well as address challenges of using this data for outcomes research.MethodsThe Military Health System manages care for approximately 10 million beneficiaries worldwide. Multiple data sources pour into the MDR from multiple levels of care (inpatient, outpatient, military or civilian facility, combat theater, etc.) at the individual patient level. To provide meaningful and descriptive coding for longitudinal analysis, specific coding for timing and type of care, procedures, medications, and provider type must be performed. Assumptions often made in clinical trials do not apply to these cohorts, requiring additional steps in data preparation to reduce risk of bias. The MDR has a robust system in place to validate the quality and accuracy of its data, reducing risk of analytic error. Details for making this data suitable for analysis of longitudinal orthopaedic outcomes are provided.ResultsAlthough some limitations exist, proper preparation and understanding of the data can limit bias, and allow for robust and meaningful analyses. There is the potential for strong precision, as well as the ability to collect a wide range of variables in very large groups of patients otherwise not captured in traditional clinical trials. This approach contributes to the improved understanding of the accessibility, quality, and cost of care for those with orthopaedic conditions.ConclusionThe MDR provides a robust pool of longitudinal healthcare data at the person-level. The benefits of using the MDR database appear to outweigh the limitations.

Arthroscopic Surgery or Physical Therapy for Patients With Femoroacetabular Impingement Syndrome: A Randomized Controlled Trial With 2-Year Follow-up:

Background: Arthroscopic hip surgery has risen 18-fold in the past decade; however, there is a dearth of clinical trials comparing surgery with nonoperative management. Purpose: To determine the comparative effectiveness of surgery and physical therapy for femoroacetabular impingement syndrome. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Patients were recruited from a large military hospital after referral to the orthopaedic surgery clinic and were eligible for surgery. Of 104 eligible patients, 80 elected to participate, and the majority were active-duty service members (91.3%). No patients withdrew because of adverse events. The authors randomly selected patients to undergo either arthroscopic hip surgery (surgery group) or physical therapy (rehabilitation group). Patients in the rehabilitation group began a 12-session supervised clinic program within 3 weeks, and patients in the surgery group were scheduled for the next available surgery at a mean of 4 months after enrollment. Patient-reported outcomes of pain, disability, and perception of improvement over a 2-year period were collected. The primary outcome was the Hip Outcome Score (HOS; range, 0-100 [lower scores indicating greater disability]; 2 subscales: activities of daily living and sport). Secondary measures included the International Hip Outcome Tool (iHOT-33), Global Rating of Change (GRC), and return to work at 2 years. The primary analysis was on patients within their original randomization group. Results: Statistically significant improvements were seen in both groups on the HOS and iHOT-33, but the mean difference was not significant between the groups at 2 years (HOS activities of daily living, 3.8 [95% CI, –6.0 to 13.6]; HOS sport, 1.8 [95% CI, –11.2 to 14.7]; iHOT-33, 6.3 [95% CI, –6.1 to 18.7]). The median GRC across all patients was that they “felt about the same” (GRC = 0). Two patients assigned to the surgery group did not undergo surgery, and 28 patients in the rehabilitation group ended up undergoing surgery. A sensitivity analysis of “actual surgery” to “no surgery” did not change the outcome. Twenty (33.3%) patients who underwent surgery and 4 (33.3%) who did not undergo surgery were medically separated from military service at 2 years. Conclusion: There was no significant difference between the groups at 2 years. Most patients perceived little to no change in status at 2 years, and one-third of military patients were not medically fit for duty at 2 years. Limitations include a single hospital, a single surgeon, and a high rate of crossover. Registration: NCT01993615 (ClinicalTrials.gov identifier)

The Influence of Exercise Dosing on Outcomes in Patients With Knee Disorders: A Systematic Review

STUDY DESIGN: Systematic review. 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. LEVEL OF EVIDENCE: Therapy, level 1a.
