BACKGROUND: Women with urgency/frequency predominant lower urinary tract symptoms (UF-LUTS) may have elevated pelvic floor muscle (PFM) position at rest and limited mobility with PFM contraction and bearing down, but this has not been quantified. OBJECTIVES: To compare PFM position and mobility using transperineal ultrasound (TPUS) at rest, maximal PFM contraction (perineal elevation), and bearing down (perineal descent) in women with and without UF-LUTS. We hypothesized that women with UF-LUTS would demonstrate elevated resting position and decreased excursion of pelvic landmarks during contraction and bearing down as compared to women without UF-LUTS. STUDY DESIGN: Case-control study METHODS: Women with UF-LUTS were matched 1:1 on age, body mass index and vaginal parity to women without UF-LUTS. TPUS videos were obtained during 3 conditions: rest, PFM contraction, and bearing down. Levator plate angle (LPA) and puborectalis length (PR length), were measured for each condition. Paired t-tests or Wilcoxon signed rank tests compared LPA and PR length between cases and controls. RESULTS: 21 case-control pairs (42 women): Women with UF-LUTS demonstrated greater LPA at rest (66.8 ± 13.2 degrees vs 54.9 ± 9.8 degrees; P=0.006), and less PR lengthening from rest to bearing down (0.2 ± 3.1 mm vs 2.1 ± 2.9 mm; P=.03). CONCLUSION: Women with UF-LUTS demonstrated more elevated (cranioventral) position of the PFM at rest and less PR muscle lengthening with bearing down. These findings highlight the importance of a comprehensive PFM examination and possible treatment for women with UF-LUTS to include PFM position and mobility.

The purpose of this exploratory analysis was to compare the impact of movement pattern training (MoveTrain) and standard strength and flexibility training (Standard) on muscle volume, strength and fatty infiltration in patients with hip-related groin pain (HRGP). We completed a secondary analysis of data collected during an assessor-blinded randomized control trial. Data was used from 27 patients with HRGP, 15 to 40 years, who were randomized into MoveTrain or Standard groups. Both groups participated in their training protocol (MoveTrain, n = 14 or Standard, n = 13) which included 10 supervised sessions over 12 weeks and a daily home exercise program. Outcome measures were collected at baseline and immediately after treatment. Magnetic resonance images (MRI) data was used to determine muscle fat index (MFI) and muscle volume. A hand-held dynamometer was used to assess isometric hip abductor and extensor strength. The Standard group demonstrated a significant post-treatment increase in gluteus medius muscle volume compared to the MoveTrain group. Both groups demonstrated an increase in hip abductor strength and reduction in gluteus minimus and gluteus maximus MFI. The magnitude of change for all outcomes were modest. Statement of Clinical Significance: Movement pattern training or a program of strength/flexibility training may be effective at improving hip abductor strength and reducing fatty infiltration in the gluteal musculature among those with HRGP. Further research is needed to better understand etiology of strength changes and impact of muscle volume and MFI in HRGP and the effect of exercise on muscle structure and function.

BACKGROUND Physical therapy and hip arthroscopy are two viable treatment options for patients with nonarthritic hip pain (NAHP); however, patients may experience considerable decisional conflict when making a treatment decision. Interdisciplinary evaluation with a physical therapist and surgeon may better inform the decision-making process and reduce decisional conflict. OBJECTIVE To identify the extent to which an interdisciplinary evaluation between a surgeon, physical therapist, and patient influences treatment plans and decisional conflict of persons with NAHP. DESIGN Randomized controlled trial. SETTING Hip preservation clinic. PARTICIPANTS Adults with primary NAHP. INTERVENTIONS Participants were randomized to receive a standard (surgeon) or interdisciplinary (surgeon+physical therapist) evaluation. Surgeon evaluations included patient interview, strength and range-of-motion examination, palpation, gross motor observation, and special testing. Interdisciplinary evaluations started with the surgeon evaluation, then a physical therapist evaluated movement impairments during sitting, sit-to-stand, standing, single-leg stance, single-leg squat, and walking. All evaluations concluded with treatment planning with the respective provider(s). OUTCOME MEASURES Treatment plan and decisional conflict were collected pre- and postevaluation. Inclusion of physical therapy in participants' postevaluation treatment plans and postevaluation decisional conflict were compared between groups using chi-square tests and Mann-Whitney U tests, respectively. RESULTS Seventy-eight participants (39 in each group) met all eligibility criteria and were included in all analyses. Sixty-six percent of participants who received an interdisciplinary evaluation included physical therapy in their postevaluation treatment plan, compared to 48% of participants who received a standard evaluation (p = .10). Participants who received an interdisciplinary evaluation reported 6.3 points lower decisional conflict regarding their postevaluation plan (100-point scale; p = .04). The interdisciplinary and standard groups reduced decisional conflict on average 24.8 ± 18.9 and 23.6 ± 14.6 points, respectively. CONCLUSIONS Adding a physical therapist to a surgical clinic increased interest in physical therapy treatment, but this increase was not statistically significant. The interdisciplinary group displayed lower postevaluation decisional conflict; however, both groups displayed similar reductions in decisional conflict from pre- to postevaluation. This study also demonstrated the feasibility of an interdisciplinary evaluation in a hip preservation clinic.

Evidence related to physical therapist-led intervention for patients with chronic hip-related groin pain (HRGP) is limited. The purpose was to assess sustainability of treatment effects for people with HRGP undergoing two physical therapist-led interventions. We completed an ancillary analysis of a pilot multicenter, randomized clinical trial (RCT). Forty-six patients with chronic HRGP, 15-40 years, were enrolled. Patients were randomized to participate in 10 sessions over 12 weeks of either movement pattern training (MoveTrain) or traditional strength/flexibility (Standard). Participants completed self-report questionnaires before treatment and 6 and 12 months after treatment completion. Outcome measures included Hip disability and Osteoarthritis Outcome Score (HOOS), Patient Specific Functional Scale (PSFS) and Numeric Pain Rating Scale (NPRS) for average and worst pain. Continuous data were analyzed with mixed model repeated measures analysis of variance (RM-ANOVA) within each group. NPRS was analyzed using multinomial generalized estimating equations (GEE) with a cumulative logit. Reported p-values are from statistical contrasts within the RM-ANOVAs and GEEs testing a priori hypotheses regarding change from pretest to month 6, and pretest to month 12. 43/46 (93.5%) participants completed treatment, 40 (87.0%) completed 6 and 38 (82.6%) completed 12 month questionnaires. At 6 and 12 months, both groups demonstrated clinically significant improvements, compared to pretest, in all subscales of HOOS (P

Hip fracture is a leading cause of profound morbidity in individuals aged 65 years and older, ranking in the top 10 causes of loss of disability-adjusted life-years for older adults. Worldwide, the number of people with hip fracture is expected to rise significantly due to the aging population and other factors. Physical therapist management is recommended within medical, surgical, and multidisciplinary clinical practice guideline (CPGs) and is considered to be the standard of care in rehabilitation for people with hip fracture. The goal of this CPG was to review the evidence relevant to physical therapist management and to provide evidence-based recommendations for physical therapy diagnosis, prognosis, intervention, and assessment of outcome in adults with hip fracture.

Developmental dysplasia of the hip (DDH) and femoroacetabular impingement (FAI) are common hip pathologies and important risk factors for osteoarthritis, yet the disease mechanisms differ. DDH involves deficient femoral head coverage and a shortened abductor moment arm, so this study hypothesized that the cross-sectional area (CSA) of the gluteus medius/minimus muscle complex and the stabilizing iliocapsularis muscle would be larger in DDH versus FAI, without increased fatty infiltration. A longitudinal cohort identified prearthritic patients with DDH or FAI who underwent imaging before surgery. Patients with DDH and FAI (Cam, Pincer, or Mixed) were 1:1 matched based on age, sex, and body mass index. Magnetic resonance imaging was used to measure the gluteus medius/minimus complex and iliocapsularis in two transverse planes. Amira software was used to quantify muscle and noncontractile tissue. Paired samples t-tests were performed to compare muscle size and composition (p 0.05). There were no differences in the iliocapsularis muscle. Patients with DDH had significantly larger CSA of the gluteus medius/minimus complex at both transverse planes, and the noncontractile tissue proportion did not differ. The mean difference in overall muscle CSA at the anterior inferior iliac spine was 4.07 ± 7.4 cm

OBJECTIVE: To compare 3D hip kinematics during single leg squat (SLsquat) and step down, between patients with hip-related groin pain (HRGP) and asymptomatic participants. To assess relationships among hip kinematics, muscle strength and bony morphology. DESIGN: Controlled laboratory cross-sectional study. METHODS: 40 patients with HRGP and 40 matched, asymptomatic participants, 18–40 years. Hand-held dynamometry was used to assess hip abductor and external rotator strength. An 8-camera motion analysis system was used to quantify 3D kinematics during SLSquat and step down. MRI was used to quantify bony morphology. Independent t-tests and Mann-Whitney U tests were used to assess between-group differences. Pearson coefficient correlations were used to assess relationships. RESULTS: Patients with HRGP had smaller peak hip flexion angles, smaller knee flexion angles and lesser squat depth compared to asymptomatic participants during SLSquat. Among patients with HRGP, smaller hip flexion angles during SLSquat were associated with hip abductor weakness (r=.47, P =

Background Physical therapy and surgery are viable treatment options for nonarthritic hip disease (NAHD). Interdisciplinary collaboration can help patients make informed treatment decisions. Understanding how each provider can contribute is a critical first step in developing collaborative evaluation efforts. Objective The objective of this study was to describe the current evaluation of NAHD by both physical therapists and physicians, and evaluate national use of expert-recommended evaluation guidelines. Design A national survey study distributed in the United States was implemented to accomplish the objective. Methods A survey was distributed to 25,027 potential physical therapist and physician respondents. Respondents detailed their evaluation content for patients with NAHD across the following domains: patient-reported outcomes, patient history, special tests, movement assessment, clinical tests, and imaging. Respondents ranked importance of each domain using a 5-point Likert scale (not important, slightly important, important, very important, or extremely important). Odds ratios (ORs [95% CIs]) were calculated to identify the odds that physical therapists, compared with physicians, would report each evaluation domain as at least very important. Fisher exact tests were performed to identify statistically significant ORs. Results Nine hundred and fourteen participants (3.6%) completed the survey. Physical therapists were more likely to indicate movement assessment (OR: 4.23 [2.99–6.02]) and patient-reported outcomes (OR: 2.56 [1.67–3.99]) as at least very important for determining a diagnosis and plan of care. Physical therapists had lower odds of rating imaging (OR: 0.09 [0.06–0.14]) and special tests (OR: 0.72 [0.53–0.98]) as at least very important compared with physicians. Limitations This survey study did not include many orthopedic surgeons and thus, primarily represents evaluation practices of physical therapists and nonsurgical physicians. Conclusions Physical therapists were more likely to consider movement assessment very important for the evaluation of patients with NAHD, whereas physicians were more likely to consider imaging and special testing very important.

Objective The purpose of this study was to describe movement impairments for persons with femoroacetabular impingement syndrome and their association with function, treatment recommendations, and treatment plans. Methods This report is a secondary, observational analysis of a clinical trial dataset in which participants received an interdisciplinary evaluation from a surgeon and physical therapist. The therapist documented frontal and sagittal plane movement impairments across 6 functional tasks. Associations between number of impairments in each plane and function (33-item International Hip Outcome Tool [iHOT33]) were evaluated using Pearson or Spearman correlations. Joint provider recommendations (physical therapist and surgeon) and participant-reported treatment plans were dichotomized based on the inclusion of physical therapy or not. Logistic regressions were used to examine the effects of (1) iHOT33, total movement impairments, and previous physical therapist treatment on joint provider recommendation and (2) these same variables along with joint provider recommendation on participant treatment plan; prevalence ratios and 95% CIs were reported for significant contributors. Results Thirty-nine participants demonstrated an average iHOT33 of 35.0 (SD = 19.5) and presented with a median 5 frontal and 3 sagittal plane impairments. More frontal plane impairments were associated with worse iHOT33 scores. Twenty-seven participants received a joint provider recommendation that included physical therapy; no significant contributors to these recommendations were identified. Twenty-four of the 27 participants with a physical therapist recommendation included physical therapy in their treatment plan. Two additional participants did not receive a physical therapist recommendation but included physical therapy in their plan. Joint provider recommendation was the only significant contributor to the participant-reported plan (prevalence ratio = 7.06; 95% CI = 3.25–7.97). Conclusion Persons with femoroacetabular impingement syndrome displayed clinically observable movement impairments that were associated with worse function. Joint provider recommendations strongly influenced participants’ treatment plans to pursue physical therapy. Impact Physical therapists contribute new information to surgical examinations regarding movement. Joint recommendations from the physical therapist and the surgeon can influence patients’ decisions to pursue physical therapy.

Developmental dysplasia of the hip (DDH) is strongly associated with increased risk for hip osteoarthritis. Skeletal deformities undeniably contribute to detrimental biomechanical loading in dysplastic hips, but cannot explain all types of damage and symptoms that patients with DDH experience. Characterizing the geometry and function of the muscles spanning the hip is a logical next step in our progression of knowledge about DDH pathomechanics. In this study, we compared skeletal geometry, muscle volumes, intramuscular fatty infiltration, moment arms, and isometric strength in patients with DDH (N=20) to healthy controls (N=15). Femoral coverage was significantly less in patients (p

© Author(s) (or their employer(s)) 2019. Hip-related pain can significantly impact quality of life, function, work capacity, physical activity and family life. Standardised measurement methods of physical capacity of relevance to young and middle-aged active adults with hip-related pain are currently not established. The aim of this consensus paper was to provide recommendations for clinical practice and research on standardised measurement methods of physical capacity in young and middle-aged active adults with hip-related pain. Four areas of importance were identified: (1) clinical measures (range of motion, muscle strength, functional impairments), (2) laboratory-based measures (biomechanics and muscle function (muscle activity, size and adiposity)), (3) physical activity, and (4) return to sport/performance. The literature was reviewed, and a summary circulated to the working group to inform discussion at the consensus meeting. The working group developed clinical and research recommendations from the literature review, which were further discussed and modified within the working group at the consensus meeting. These recommendations were then presented to all 38 International Hip-related Pain Research Network (IHiPRN) participants for further discussion, refinement and consensus voting. Therefore, the recommendations voted on were based on a combination of current evidence and expert opinion. The consensus meeting voted on 13 recommendations, six of which were clinically orientated, and seven more research specific. We recommended that clinicians working with young and middle-aged active adults with hip-related pain assess strength using objective methods of measurement, and clinically assess performance of functional tasks, including walking and running. Physical activity should be quantified using both self-reported and objective measures, and patient expectations of recovery should be quantified prior to treatment. It was recommended that return to physical activity (including sport and occupation) be quantified, and sport-specific activities should be assessed prior to return to sport. The IHiPRN participants were uncertain regarding recommendations for range of motion assessment. Research recommendations were that the measurement properties of range of motion, strength and functional performance tests be investigated, reported and improved in both clinical and research settings. Reporting of movement-related parameters (biomechanics and muscle function) should be standardised and the relationship among movement-related parameters, symptoms, function, quality of life, and intra-articular and imaging findings should be investigated. Quantification of return to physical activity (including sport and occupational demands) is required in future research, and the return to sport continuum should be used. Future research is required to determine the best criteria for rehabilitation progression and return to physical activity following hip-related pain management.

BACKGROUND: Urgency and frequency are common lower urinary tract symptoms (UF-LUTS) in women. There is limited evidence to guide physical therapist-led treatment. OBJECTIVES: To compare hip and pelvic floor muscle strength between women with and without UF-LUTS. We hypothesized women with UF-LUTS would demonstrate 1) diminished hip external rotator and abductor strength and 2) equivalent pelvic floor strength and diminished endurance compared to controls. STUDY DESIGN: A matched case-control study METHODS: Women with UF-LUTS (cases) and controls were matched on age, body mass index (BMI), vaginal parity. Examiner measured participants’ 1) hip external rotator and abductor strength via dynamometry (maximum voluntary effort against fixed resistance) and 2) pelvic floor muscle strength (peak squeeze pressure) and endurance (squeeze pressure over a 10 second hold) via vaginal manometry. Values compared between cases and controls with paired-sample t-tests (hip) or Wilcoxon signed rank tests (pelvic floor). RESULTS: 21 pairs (42 women): Hip external rotation (67.0 ± 19.0 N vs 83.6 ± 21.5 N; P=0.005) and hip abduction strength (163.1 ± 48.1 N vs 190.1 ± 53.1 N; P=0.04) were significantly lower in cases than controls. There was no significant difference in pelvic floor strength (36.8 ± 19.9 cmH(2)0 vs 41.8 ± 21.0 cmH(2)0; P=0.40) or endurance (234.0 ± 149.6 cmH(2)0*seconds vs 273.4 ± 149.1 cmH(2)0*seconds; P=0.24). CONCLUSION: Women with UF-LUTS had weaker hip external rotator and abductor muscles, but similar pelvic floor strength and endurance compared to controls. Hip strength may be important to assess in patients with UF-LUTS, further research is needed.

OBJECTIVES: 1) examine the relationship between spine, hip, and pelvis movement patterns and urinary urgency and frequency 2) report the prevalence of pelvic girdle and hip joint impairments among women with and without urinary urgency and frequency 3) report the most common movement impairments observed in women with and without urinary urgency and frequency. METHODS: Women age 18–60 with urinary urgency and frequency were matched 1:1 to women without on age, body mass index, and vaginal parity. Participants completed primary movement tests of the hip, pelvis and spine. Additional clinical tests included Stork test, sidelying position, pubic symphysis palpation, flexion-abduction-external rotation, flexion-adduction-internal rotation, and seated hip internal and external rotation. Urge symptoms were monitored before and during each test. Movement patterns and positioning of the thoracic and lumbar spine, pelvis, and hips were observed. Secondary tests to correct a movement or positional impairment were performed if an impairment was noted or if symptoms were provoked during the primary test. RESULTS: 42 women completed testing. More participants with urinary urgency and frequency 1) demonstrated impairments during forward bend, single leg stance, sidelying and Stork tests; 2) reported urgency provocation during forward bend, flexion-adduction-internal rotation test, pubic symphysis palpation, and hip internal rotation; and 3) reported symptom relief with sidelying position secondary test; and secondary tests of the thoracic, lumbar and hip regions compared to those without. CONCLUSION: Musculoskeletal impairments may be associated with urinary urgency and frequency and should therefore be considered when determining management options for these patients.

There is no agreement on how to classify, define or diagnose hip-related pain—a common cause of hip and groin pain in young and middle-aged active adults. This complicates the work of clinicians and researchers. The International Hip-related Pain Research Network consensus group met in November 2018 in Zurich aiming to make recommendations on how to classify, define and diagnose hip disease in young and middle-aged active adults with hip-related pain as the main symptom. Prior to the meeting we performed a scoping review of electronic databases in June 2018 to determine the definition, epidemiology and diagnosis of hip conditions in young and middle-aged active adults presenting with hip-related pain. We developed and presented evidence-based statements for these to a panel of 37 experts for discussion and consensus agreement. Both non-musculoskeletal and serious hip pathological conditions (eg, tumours, infections, stress fractures, slipped capital femoral epiphysis), as well as competing musculoskeletal conditions (eg, lumbar spine) should be excluded when diagnosing hip-related pain in young and middle-aged active adults. The most common hip conditions in young and middle-aged active adults presenting with hip-related pain are: (1) femoroacetabular impingement (FAI) syndrome, (2) acetabular dysplasia and/or hip instability and (3) other conditions without a distinct osseous morphology (labral, chondral and/or ligamentum teres conditions), and that these terms are used in research and clinical practice. Clinical examination and diagnostic imaging have limited diagnostic utility; a comprehensive approach is therefore essential. A negative flexion–adduction–internal rotation test helps rule out hip-related pain although its clinical utility is limited. Anteroposterior pelvis and lateral femoral head–neck radiographs are the initial diagnostic imaging of choice—advanced imaging should be performed only when requiring additional detail of bony or soft-tissue morphology (eg, for definitive diagnosis, research setting or when planning surgery). We recommend clear, detailed and consistent methodology of bony morphology outcome measures (definition, measurement and statistical reporting) in research. Future research on conditions with hip-related pain as the main symptom should include high-quality prospective studies on aetiology and prognosis. The most common hip conditions in active adults presenting with hip-related pain are: (1) FAI syndrome, (2) acetabular dysplasia and/or hip instability and (3) other conditions without distinct osseous morphology including labral, chondral and/or ligamentum teres conditions. The last category should not be confused with the incidental imaging findings of labral, chondral and/or ligamentum teres pathology in asymptomatic people. Future research should refine our current recommendations by determining the clinical utility of clinical examination and diagnostic imaging in prospective studies.

Rehabilitation for patients with developmental dysplasia of the hip (DDH) addresses modifiable factors in an effort to reduce symptoms and prevent or delay the development of osteoarthritis, yet its effect on joint mechanics remains unknown. Our objective was to establish how rehabilitation (muscle strengthening and movement training), simulated with a musculoskeletal model and probabilistic analyses, alters hip joint reaction forces (JRF) in patients with DDH during a single limb squat. In four patients with DDH, hip abductor strengthening was simulated by increasing the maximum isometric force value between 0 and 32.6% and movement training was simulated by decreasing the hip adduction angle between 0 and 10° relative to baseline. 2,000 Monte Carlo simulations were performed separately to simulate strengthening and movement training, from which 99% confidence bounds and sensitivity factors were calculated. Our results indicated that simulated movement training aimed at decreasing hip adduction had a substantially larger influence on hip JRF than strengthening, as indicated by 99% confidence bounds of the resultant JRF (0.88 ± 0.55 xBW vs. 0.31 ± 0.12 xBW, respectively). Relative to baseline, movement training that resulted in a 10° decrease in hip adduction decreased the resultant JRF by 0.78 ± 0.65 xBW, while strengthening the abductors by 17.6% increased resultant JRF by 0.18 ± 0.06 xBW. To our knowledge, these results are the first to provide evidence pertaining to the effect of rehabilitation on joint mechanics in patients with DDH and can be used to inform more targeted interventions.

Context: The authors hypothesized that in people with hip-related groin pain, less static ankle dorsiflexion could lead to compensatory hip adduction and contralateral pelvic drop during step-down. Ankle dorsiflexion may be a modifiable factor to improve ability in those with hip-related groin pain to decrease hip/pelvic motion during functional tasks and improve function. Objective: To determine whether smaller static ankle dorsiflexion angles were associated with altered ankle, hip, and pelvis kinematics during step-down in people with hip-related groin pain. Design: Cross-sectional Setting: Academic medical center. Patients: A total of 30 people with hip-related groin pain (12 males and 18 females; 28.7 [5.3] y) participated. Intervention: None. Main Outcome Measures: Weight-bearing static ankle dorsiflexion with knee flexed and knee extended were measured via digital inclinometer. Pelvis, hip, and ankle kinematics during forward step-down were measured via 3D motion capture. Static ankle dorsiflexion and kinematics were compared with bivariate correlations. Results: Smaller static ankle dorsiflexion angles were associated with smaller ankle dorsiflexion angles during the step-down for both the knee flexed and knee extended static measures. Among the total sample, smaller static ankle dorsiflexion angle with knee flexed was associated with greater anterior pelvic tilt and greater contralateral pelvic drop during the step-down. Among only those who did not require a lowered step for safety, smaller static ankle dorsiflexion angles with knee flexed and knee extended were associated with greater anterior pelvic tilt, greater contralateral pelvic drop, and greater hip flexion. Conclusions: Among those with hip-related groin pain, smaller static ankle dorsiflexion angles are associated with less ankle dorsiflexion motion and altered pelvis and hip kinematics during a step-down. Future research is needed to assess the effect of treating restricted ankle dorsiflexion on quality of motion and symptoms in patients with hip-related groin pain.

Study designPilot, multicentre randomised clinical trial (RCT).ObjectivesAssess viability of performing a definitive RCT and compare preliminary effects of movement pattern training (MoveTrain) and strengthening/flexibility (Standard) to improve function in people with chronic hip-related groin pain (HRGP).BackgroundTo determine the best physical therapist-led intervention for patients with HRGP, we must understand treatment effects of different treatment modes.MethodsForty-six patients (17M:29F; 29±5.3 years; body mass index 25.6±6.3 kg/m2) with HRGP were randomised. MoveTrain included task-specific training to optimise biomechanics during daily tasks. Standard included strengthening/flexibility. Treatment included 10 visits/12 weeks and home exercise programme (HEP). Primary outcomes for feasibility were recruitment, retention, treatment adherence and treatment fidelity. Secondary outcomes were patient-reported function (Hip disability and Osteoarthritis Outcome Score (HOOS)), lower extremity kinematics and hip muscle strength.ResultsWe achieved target recruitment, and retention was excellent (91%). Patient session attendance was high (93%); however, reported HEP adherence (62%) was lower than expected. Physical therapists’ adherence to treatment protocols was high (90%). Patients demonstrated high treatment receipt; 91% of exercises performed were rated independent. Both groups demonstrated clinically important improvements in function (HOOS) and muscle strength; however, there were no between-group differences (HOOS subscales, p≥0.13, strength, p≥0.34). Compared with Standard, MoveTrain demonstrated greater reductions in hip adduction (p=0.016) and pelvic drop (p=0.026) during a single leg squat. No adverse events were noted.ConclusionOur experience in completing this RCT confirmed that a larger, multicentre RCT is feasible and highlighted modifications we will implement to optimise the future RCT.Trial registration numberNCT02913222.

Hip-related pain is a well-recognised complaint among active young and middle-aged active adults. People experiencing hip-related disorders commonly report pain and reduced functional capacity, including difficulties in executing activities of daily living. Patient-reported outcome measures (PROMs) are essential to accurately examine and compare the effects of different treatments on disability in those with hip pain. In November 2018, 38 researchers and clinicians working in the field of hip-related pain met in Zurich, Switzerland for the first International Hip-related Pain Research Network meeting. Prior to the meeting, evidence summaries were developed relating to four prioritised themes. This paper discusses the available evidence and consensus process from which recommendations were made regarding the appropriate use of PROMs to assess disability in young and middle-aged active adults with hip-related pain. Our process to gain consensus had five steps: (1) systematic review of systematic reviews; (2) preliminary discussion within the working group; (3) update of the more recent high-quality systematic review and examination of the psychometric properties of PROMs according to established guidelines; (4) formulation of the recommendations considering the limitations of the PROMs derived from the examination of their quality; and (5) voting and consensus. Out of 102 articles retrieved, 6 systematic reviews were selected and assessed for quality according to AMSTAR 2 (A MeaSurement Tool to Assess systematic Reviews). Two showed moderate quality. We then updated the most recent review. The updated literature search resulted in 10 additional studies that were included in the qualitative synthesis. The recommendations based on evidence summary and PROMs limitations were presented at the consensus meeting. The group makes the following recommendations: (1) the Hip and Groin Outcome Score (HAGOS) and the International Hip Outcome Tool (iHOT) instruments (long and reduced versions) are the most appropriate PROMs to use in young and middle-aged active adults with hip-related pain; (2) more research is needed into the utility of the HAGOS and the iHOT instruments in a non-surgical treatment context; and (3) generic quality of life measures such as the EuroQoL-5 Dimension Questionnaire and the Short Form Health Survey-36 may add value for researchers and clinicians in this field. We conclude that as none of the instruments shows acceptable quality across various psychometric properties, more methods studies are needed to further evaluate the validity of these PROMS—the HAGOS and iHOT—as well as the other (currently not recommended) PROMS.

BACKGROUND: In 2014, the total prevalence of diabetes was estimated to be 422 million people worldwide. Due to the aging population and continued increase in obesity rates, the prevalence is expected to rise to 592 million by 2035. Diabetes can lead to several complications, including cardiovascular disease, stroke, peripheral arterial disease, nephropathy, neuropathy, retinopathy, lower extremity amputation, and musculoskeletal impairments. CLINICAL QUESTION: Up to 80% of patients referred for outpatient physical therapy have diabetes or are at risk for diabetes, providing an opportunity for physical therapists to intervene. Therefore, we asked, “What is the role of physical therapists in fighting the diabetes epidemic?” KEY RESULTS: Physical therapists commonly prescribe physical activity for the treatment of diabetes and other chronic diseases, such as cardiovascular disease and osteoarthritis. Physical therapists may also screen for risk factors for diabetes and diabetes-related complications and modify traditional musculoskeletal exercise prescription accordingly. Physical therapists must advocate for regular physical activity as a key component of the treatment of chronic diseases in all patient interactions. CLINICAL APPLICATION: This commentary (1) describes the diabetes epidemic and the health impact of diabetes and diabetes-related complications, (2) highlights the physical therapist’s role as front-line provider, and (3) provides recommendations for physical therapists in screening for diabetes risk factors and diabetes-related complications and considerations for patient management. We focus on type 2 diabetes.

The 1st International Hip-related Pain Research Network meeting discussed four prioritised themes concerning hip-related pain in young to middle-aged adults: (1) diagnosis and classification of hip-related pain; (2) patient-reported outcome measures for hip-related pain; (3) measurement of physical capacity for hip-related pain; (4) physiotherapist-led treatment for hip-related pain. Thirty-eight expert researchers and clinicians working in the field of hip-related pain attended the meeting. This manuscript relates to the theme of physiotherapist-led treatments for hip-related pain. A systematic review on the efficacy of physiotherapist-led interventions for hip-related pain (published separately) was conducted and found that strong evidence for physiotherapist-led treatments was lacking. Prior to the meeting, draft consensus recommendations for consideration in the meeting were also developed based on the systematic review. The draft consensus recommendations were presented to all of the meeting participants via email, at least 1 week prior to the meeting. At the meeting, these recommendations were discussed, revised and voted on. Six recommendations for clinical practice and five recommendations for research were included and all gained consensus. Recommendations for clinical practice were that (i) Exercise-based treatments are recommended for people with hip-related pain. (ii) Exercise-based treatment should be at least 3 months duration. (iii) Physiotherapist-led rehabilitation after hip surgery should be undertaken. (iv) Patient-reported outcome measures, measures of physical impairment and measures of psychosocial factors should be used to monitor response to treatment. (v) Physical activity (that may include sport) is recommended for people with hip-related pain. (vi) Clinicians should discuss patient expectations, use shared-decision making and provide education. Recommendations for research were (i) Reporting of exercise programmes: Exercise descriptors such as load magnitude, number of repetitions and sets, duration of whole programme, duration of contractile element of exercise, duration of one repetition, time under tension, rest between repetitions, range of motion through which the exercise is performed, and rest between exercise sessions should be reported. (ii) Research should investigate the optimal frequency, intensity, time, type, volume and progression of exercise therapy. (iii) Research should examine the effect of patient education in people with hip-related pain. (iv) Research should investigate the effect of other treatments used in people with hip-related pain (for example: manual therapy, medications, injections). (v) Research should examine the impact of comorbidities and social determinants on treatment effectiveness in people with hip-related pain. Clinicians and researchers working with young to middle-aged active adults with hip-related pain may use these consensus recommendations to guide, develop, test and implement individualised, evidence-based physiotherapist-led rehabilitation programmes.

The purpose of this narrative review was to present and review the evidence of the relationship of musculoskeletal impairments found in people with non-specific chronic pelvic pain (CPP). The musculoskeletal impairments assessed in this review include pelvic floor muscle: performance, resting state, strength, activation, posture and movement patterns. A search was performed systematically using PubMed, Cochrane, CINAHL, Embase, and Web of Science databases from 1998 to 2018 to identify studies reporting the relationship of non-specific CPP and musculoskeletal impairments of the hip, pelvis and trunk. The search resulted in 2106 articles that were screened by 2 authors. Remaining articles were screened by an additional 2 authors for inclusion in this review. Thirty-one articles remained after initial screening. Full text publications were reviewed and an additional 25 articles were excluded. Six additional articles were located through review of the reference lists of included articles. The final review included 12 publications. Seven of these studies were cross-sectional cohorts or a case-control comparing patients with CPP to asymptomatic controls. One cohort study included patients with CPP alone. The remaining studies were treatment studies. The level of evidence for the studies included in this review was low at levels 4 and 5. We were unable to make clear conclusions regarding the relationships of musculoskeletal impairments and CPP because validity and use of terms and assessments were inconsistent. Further research is needed with standardized definitions and measurements to better understand the musculoskeletal system as it relates to nonspecific CPP.

BACKGROUND: Non-arthritic hip disease (NAHD) is a clinical condition often accompanied by painful movement. Current literature is lacking regarding how movement abnormalities are evaluated and treated in this population, which may be key to identifying which patients may respond to non-operative versus operative treatment. Combining the expertise of a hip arthroscopist and physical therapist may better inform treatment decisions for persons with NAHD. The primary objective of this study is to identify the extent to which an interdisciplinary evaluation between a physical therapist and surgeon influences treatment decisions of persons presenting to a hip preservation clinic. RATIONALE FOR STUDY DESIGN: A prospective, randomized controlled trial provides the ability to identify cause and effect of this new evaluation type. METHODS: Ninety-six adults with unilateral, NAHD presenting to a hip preservation clinic for initial evaluation will be randomized to receive either a standard evaluation with a surgeon or an interdisciplinary evaluation by a physical therapist and surgeon. Regardless of group, the surgeon conducts a standard-care examination. For participants in the interdisciplinary group, the physical therapist conducts an assessment of 6 postures and movements to identify asymmetrical, abnormal, or painful strategies. Treatment selection(s) and decisional conflict will be compared between groups after the evaluations. DISCUSSION: Persons with NAHD may experience considerable decisional conflict because of prolonged duration of symptoms and minimal evidence to compare operative and non-operative treatment for this population. The findings of this study have the potential to improve patient experience and produce more informed and supported treatment decisions for persons considering surgical treatment for NAHD.

Athletic activity is a proposed factor in the development and progression of intra-articular hip pathology. Early diagnosis and preventive treatments in "at-risk" athletes are needed.Our primary objective was to report hip range of motion (ROM) and prevalence of positive impingement testing in asymptomatic college freshman athletes. Our secondary objective was to determine whether an association exists between hip ROM and a positive flexion-adduction-internal rotation (FADIR) test.Cross-sectional study.Collegiate athletic campus.Four hundred thirty (299 male, 131 female) freshman athletes reporting no current or previous hip pain.During the athletes' preseason medical screening, trained examiners performed a hip-specific exam to obtain data for hip ROM and impingement testing.Bilateral passive ROM measures included hip flexion, and hip internal and external rotation with the hip flexed 0° and 90°.Mean age of male participants was 18.5 ± 0.8 and female participants was 18.3 ± 0.6 years (P = .003). Male participants demonstrated less hip ROM than female participants in flexion (115.8 ± 11.2° versus 122.0 ± 10.5°, P.001), internal rotation in 90° flexion (26.9 ± 9.8° versus 34.7 ± 10.7°, P.001) and 0° flexion (29.0 ± 9.8° versus 38.9 ± 10.1°, P.001), and external rotation in 90° flexion (44.7 ± 10.9° versus 49.7 ± 10.4°, P.001) but not for external rotation in 0° flexion (39.8 ± 11.1° versus 37.6 ± 11.5°, P = .06). Pain with FADIR test on the right and left hip were reported in 11.9% and 14.5% of athletes, respectively. Gender and a positive FADIR were not related (male 12.2%, female 15.3%, P = .36).In asymptomatic college freshman athletes, male athletes generally demonstrated less hip ROM than female athletes. In addition, a positive FADIR was more prevalent than previously reported in healthy young adults. Preseason screenings that use these baseline data in conjunction with other examination findings may allow identification of athletes at future risk for hip pain and/or injury.IV.

Study Design Feasibility randomized clinical trial. Background Rehabilitation may be an appropriate treatment strategy for patients with chronic hip joint pain; however, the evidence related to the effectiveness of rehabilitation is limited. Objectives To assess feasibility of performing a randomized clinical trial to investigate the effectiveness of movement-pattern training (MPT) to improve function in people with chronic hip joint pain. Methods Thirty-five patients with chronic hip joint pain were randomized into a treatment (MPT) group or a control (wait-list) group. The MPT program included 6 one-hour supervised sessions and incorporated (1) task-specific training for basic functional tasks and symptom-provoking tasks, and (2) strengthening of hip musculature. The wait-list group received no treatment. Primary outcomes for feasibility were patient retention and adherence. Secondary outcomes to assess treatment effects were patient-reported function (Hip disability and Osteoarthritis Outcome Score), lower extremity kinematics, and hip muscle strength. Results Retention rates did not differ between the MPT (89%) and wait-list groups (94%, P = 1.0). Sixteen of the 18 patients (89%) in the MPT group attended at least 80% of the treatment sessions. For the home exercise program, 89% of patients reported performing their home program at least once per day. Secondary outcomes support the rationale for conduct of a superiority randomized clinical trial. Conclusion Based on retention and adherence rates, a larger randomized clinical trial appears feasible and warranted to assess treatment effects more precisely. Data from this feasibility study will inform our future clinical trial. Level of Evidence Therapy, level 2b-. J Orthop Sports Phys Ther 2016;46(6):452-461.

Introduction: Both physical therapy (PT) and surgery appear to have some efficacy in treating femoroacetabular impingement (FAI). Only recently have high-level evidence studies compared these two options, though results of these randomized controlled trials (RCTs) are contradictory. The purpose of this study was to perform a systematic review and meta-analysis of RCTs comparing PT and surgery in patients with FAI. Methods: A systematic review was performed to identify randomized trials comparing FAI and PT. Data was extracted for demographics, study design, patient reported outcomes (PROs), and study quality/bias. In total, 819 abstracts were reviewed, with three RCTs identified (Griffin 2018, Mansell 2018, and Palmer 2019). All three RCTs reported iHOT-33, while two studies reported HOS ADL and Sport (Mansell 2019 and Palmer 2019). In a random effects meta-analysis, between-group differences in post-intervention scores were assessed using intention-to-treat analysis in each study. Results: All 3 RCTs reported PROs improvement from baseline to follow-up for both PT and surgery. The meta-analysis demonstrated greater improved iHOT-33 outcomes with surgery compared to PT with a mean relative difference of 11.3 (95% CI 1.86-20.73, p=0.014). The meta-analysis for HOS ADL and Sports (two RCTs) similarly demonstrated higher scores with surgery with a mean difference of 3.9 (95% CI -9.6-17.3, p=0.571) and 6.2 (95% CI -6.8-19.2, p=0.347), respectively, though without statistical significance. The quality of two RCTs was assessed as good with minimal bias (Griffin and Palmer). In the third RCT, an extremely high crossover rate may affect its validity (Mansell 2018, 70% crossover from PT to surgery). For instance, HOS ADL outcome based on treatment received, adjusting for Mansell’s crossover rate, favored surgery with a larger mean difference of 12.0 (95% CI 7.5-16.5, pDiscussion: In patients with FAI, combined results of three RCTs demonstrate superior outcomes of surgery compared to PT. However, PT can result in improvements in some patients and does not appear to compromise surgical outcomes. Provided that the studies adjusted for certain patient characteristics, further research needs to identify patient characteristics that predict success of non-operative and operative treatment of FAI in specific patient subgroups.

OBJECTIVE: Describe the proportional occurrence of visually determined, lower extremity movement patterns (dynamic knee valgus [DKVal], neutral [NEU], dynamic knee varus [DKVar]) during a single leg squat (SLSquat) among patients with chronic hip joint pain (CHJP). Compare 3D hip and pelvic kinematics among the categories and determine whether within-session movement pattern changes are possible among those who demonstrate DKVal or DKVar. DESIGN: Cross-sectional. SETTING: Movement science laboratory. PARTICIPANTS: 36 patients with CHJP (18 to 40 years). MAIN OUTCOME MEASURES: Visually-based classification of lower extremity movement and 3D kinematic angles of hip and pelvis during SLSquat, performed under usual (self-selected) and modified (therapist instruction) conditions. RESULTS: Based on visual appraisal, 14 patients demonstrated DKVal, 22 demonstrated NEU and none demonstrated DKVar. Those with DKVal demonstrated greater hip adduction (23.5±5.7° vs. 16.0±5.7°, p

Study Design Ancillary analysis, time-controlled randomized clinical trial. Background Movement-pattern training (MPT) has been shown to improve function among patients with chronic hip joint pain (CHJP). Objective To determine the association among treatment outcomes and mechanical factors associated with CHJP. Methods Twenty-eight patients with CHJP, 18 to 40 years of age, participated in MPT, either immediately after assessment or after a wait-list period. Movement-pattern training included task-specific training to reduce hip adduction motion during functional tasks and hip muscle strengthening. Hip-specific function was assessed using the Modified Harris Hip Score (MHHS) and Hip disability and Osteoarthritis Outcome Score (HOOS). Three-dimensional kinematic data were used to quantify hip adduction motion, dynamometry to quantify abductor strength, and magnetic resonance imaging to measure femoral head sphericity using the alpha angle. Paired t tests assessed change from pretreatment to posttreatment. Spearman correlations assessed associations. Results There was significant improvement in MHHS and HOOS scores (P≤.02), adduction motion (P = .045), and abductor strength (P = .01) from pretreatment to posttreatment. Reduction in hip adduction motion (r = -0.67, P

Innovations in biologics offer great promise in the treatment of patients with orthopaedic conditions and in advancing our ability to monitor underlying disease pathophysiology. Our understanding of the pathophysiology of hip osteoarthritis (OA) has improved significantly in the last decade. Femoroacetabular impingement (FAI) and hip dysplasia are increasingly recognized and treated as forms of prearthritic hip disease, yet the inability of radiographic and MR imaging to identify patients before the onset of irreversible articular cartilage injury limits their use for early diagnosis and treatment of patients with these conditions. Molecular biomarkers, as objectively measureable indicators of the pathophysiology of hip OA, have the potential to improve diagnosis, disease staging, and prognosis of hip OA and prearthritic hip disease. Although research into molecular biomarkers of hip OA has been conducted, investigations in prearthritic hip disease have only recently begun.The purpose of our review was to assess the use of molecular biomarkers in the pathophysiology of hip OA, including (1) diagnosis; (2) disease staging; and (3) prognosis. We additionally aimed to summarize the available literature investigating the use of biomarkers in (4) prearthritic hip disease, including FAI and hip dysplasia.We conducted a systematic review of molecular biomarkers associated with hip OA or prearthritic hip disease by searching four major electronic databases for keywords "hip", "osteoarthritis", "biomarker", and all synonyms. The search terms "femoroacetabular impingement" and "hip dysplasia" were also included. The biologic source of biomarkers was limited to serum, plasma, urine, and synovial fluid. The literature search yielded a total of 2740 results. Forty studies met all criteria and were included in our review. Studies were categorized regarding their relevance to (1) diagnosis; (2) disease staging; (3) prognosis; and/or (4) prearthritic hip disease.Biomarker studies were characterized as relevant to diagnosis (16 studies), disease staging (15 studies), prognosis (11 studies), and prearthritic hip disease (three studies). Sixteen different biomarkers demonstrated associations relevant to the diagnosis of hip OA, 16 biomarkers demonstrated similar associations for disease staging, and six for prognosis. Six biomarkers seemed to be the most promising, demonstrating associations with hip OA in multiple studies, including: urinary level of type II collagen telopeptide (n = 5 studies), serum cartilage oligomeric protein (n = 4 studies), and serum C-reactive protein (n = 4 studies). Only three studies investigated the role of biomarkers in prearthritic hip disease, including two in FAI and one in unspecified etiology of pain. There were no studies about biomarkers in hip dysplasia.Molecular biomarkers are increasingly investigated for their use in evaluating the pathophysiology of hip OA, but less so for prearthritic hip disease. Several biomarkers have demonstrated significant associations with hip OA across multiple studies. Further validation of these biomarkers is needed to assess their clinical use and potential application to prearthritic hip disease.

Study Design Secondary analysis, cross-sectional study. Background Chronic hip joint pain (CHJP) can lead to limitations in activity participation, but the musculoskeletal factors associated with the condition are relatively unknown. Understanding the factors associated with CHJP may help develop rehabilitation strategies to improve quality of life of individuals with long-term hip pain. Objectives To compare measures of hip abductor muscle volume and hip abductor muscle strength between women with CHJP and asymptomatic controls. Methods Thirty women, 15 with CHJP and 15 matched asymptomatic controls (age range, 18-40 years), participated in this study. Magnetic resonance imaging was used to determine the volume of the primary hip abductor muscles, consisting of the gluteus medius, gluteus minimus, a small portion of the gluteus maximus, and the tensor fascia latae, within a defined region of interest. Break tests were performed using a handheld dynamometer to assess hip abductor strength. During the strength test, the participant was positioned in sidelying with the involved hip in 15° of abduction. Independent-samples t tests were used to compare muscle volume and strength values between those with CHJP and asymptomatic controls. Results Compared to asymptomatic controls, women with CHJP demonstrated significantly increased gluteal muscle volume (228 ± 40 cm

Controlled laboratory cross-sectional study. Objectives To assess strength differences of the hip rotator and abductor muscle groups in young adults with chronic hip joint pain (CHJP) and asymptomatic controls. A secondary objective was to determine if strength in the uninvolved hip of those with unilateral CHJP differs from that in asymptomatic controls.Little is known about the relationship between hip muscle strength and CHJP in young adults.Thirty-five participants with CHJP and 35 matched controls (18 to 40 years of age) participated. Using handheld dynamometry, strength of the hip external rotators and internal rotators was assessed with the hip flexed to 90° and 0°. To assess external rotator and internal rotator strength, the hip was placed at the end range of external rotation and internal rotation, respectively. Strength of the hip abductors was assessed in sidelying, with the hip in 15° of abduction. Break tests were performed to determine maximum muscle force, and the average torque was calculated using the corresponding moment arm. Independent-sample t tests were used to compare strength values between (1) the involved limb in participants with CHJP and the corresponding limb in the matched controls, and (2) the uninvolved limb in participants with unilateral CHJP and the corresponding limb in the matched controls.Compared to controls, participants with CHJP demonstrated weakness of 16% to 28% (P.01) in all muscle groups tested in the involved hip. The uninvolved hip of 22 subjects with unilateral CHJP demonstrated weakness of 18% and 16% (P.05) in the external rotators (0°) and abductors, respectively, when compared to the corresponding limb of the matched controls.The results of the present study demonstrate that persons with CHJP have weakness in the hip rotator and hip abductor muscles. Weakness also was found in the uninvolved hip of persons with CHJP.

The Orthopaedic Section of the American Physical Therapy Association (APTA) has an ongoing effort to create evidence-based practice guidelines for orthopaedic physical therapy management of patients with musculoskeletal impairments described in the World Health Organization's International Classification of Functioning, Disability, and Health (ICF). The purpose of these clinical practice guidelines is to describe the peer-reviewed literature and make recommendations related to nonarthritic hip joint pain. J Orthop Sports Phys Ther. 2014;44(6):A1–A32. doi:10.2519/jospt.2014.0302

The primary objective of this study was to use step activity monitoring to quantify activity changes after total hip arthroplasty in patients 50 years or less. Secondly, we investigated whether step activity measurements correlated with the Harris hip and UCLA scores. We prospectively analyzed 37 patients (age ≤ 50) treated with primary THA. Patient activity was recorded with a step activity monitor. Harris hip and UCLA scores were analyzed. Total daily stride counts increased by an average of 30.0%. Increases were noted in the percent of daily time spent at high, moderate and low activity. Increases in daily time spent at high activity moderately correlated with the UCLA activity score but did not correlate with the HHS. Both the UCLA score and the HHS did not correlate with mean daily strides. Following THA, patients ≤ 50 years of age increase their activity by taking more daily strides and improve their activity profile by spending more time at higher activity. Improvements in step activity moderately correlate with improvements in UCLA scores.

Objective To describe outcomes of the conservative treatment of patients who had the clinical presentation of a prearthritic, intra-articular hip disorder, including acetabular labral tears, developmental hip dysplasia, and femoroacetabular impingement. Design Prospective observational clinical outcomes study. Setting Outpatient orthopedic clinic at a tertiary university hospital. Patients Patients presenting with prearthritic, intra-articular hip disorders were recruited. Fifty-eight consecutive patients were enrolled; 6 were lost to follow-up, and 52 subjects completed the study. Methods Patients were recruited on the basis of symptoms, distribution of pain, and the findings of a physical examination. Radiographic measurements of the hip were obtained for all subjects to describe the presence or absence and extent of deformity and/or osteoarthritis. All subjects completed a directed course of conservative treatment. After 3 months of conservative care, subjects with continued limitations, reduction of symptoms with a diagnostic intra-articular hip injection, and a surgically amenable lesion found on a magnetic resonance arthrogram proceeded to surgery. Main Outcome Measurements Numeric Pain Score (0-10), Short Form-12, Modified Harris Hip Score, Western Ontario and McMaster Universities Osteoarthritis Index, Nonarthritic Hip Score, Baecke Questionnaire of Habitual Activity, and patient choice to have surgery. Results Fifty-eight patients (9 men and 49 women) with a mean age of 35 ± 11 years (range, 18-50 years) enrolled in the study. Fifty-two subjects completed the study. Twenty-three subjects (44%) reported satisfaction with conservative care. Twenty-nine subjects (56%) chose to have surgery. Both groups demonstrated equally significant improvement ( P value ranges: P = .03 to P = .0001) in all outcome measures from baseline to 1-year follow-up. Subjects who chose surgery had higher baseline activity scores compared with the conservative treatment group ( P = .02). Conclusion All subjects with signs and symptoms of prearthritic, intra-articular hip disorders who were treated with conservative treatment alone and with conservative treatment followed by surgery demonstrated significant improvement in pain and functioning from baseline to 1 year. Forty-four percent of patients improved with conservative care alone, and 56% chose to have surgery after receiving conservative care. Persons with more active lifestyles were more likely to choose surgery. These data suggest that a trial of conservative management for persons with prearthritic, intra-articular hip disorders should be considered before engaging in surgical intervention.

Background Physical therapists often assess patient independence through observation; however, it is not known if therapists make these judgments reliably. We have developed a standardized method to assess a patient's ability to perform his or her treatment program independently. Objectives To develop a standardized assessment of patient independence in performance of a treatment program and examine the intra- and inter-rater reliability decisions made by two physical therapists. Design Test-retest. Methods An assessment of patient independence in performance was developed. Standardized patient scenarios were used to assess the intra- and inter-tester reliability of two physical therapists. Percentage of agreement (%) and kappa's coefficient (k and k(w)) indexed rater reliability. Results Intra-rater reliability of therapist 1 was as follows: knowledge: % = 95, k = 0.90; performance: % = 95, k(w) = 0.82. Intra-rater reliability of therapist 2 was as follows: knowledge: % = 85, k = 0.68; performance: % = 94, k(w) = 0.80. Inter-rater reliability for knowledge was % = 91 and k = 0.79 and for performance was % = 91 and k(w) = 0.72. Conclusion Trained therapists displayed substantial to excellent intra-rater reliability and substantial inter-rater reliability in assessing a patient's independence in a treatment program.

Objective The classification of patients with low back pain (LBP) may be important for improving clinical outcomes and research efficiency. The purpose of this study was to examine the inter-tester reliability of 2 trained physical therapists to classify patients with LBP by using the standardized Movement System Impairment (MSI) classification system. The 5 proposed MSI classifications are based on the most consistent patterns of movement and alignment observed throughout the examination that correlate with the patient's symptom behavior. Design Test-retest to assess reliability Setting Academic healthcare center outpatient facility Participants Thirty subjects (21 women and 9 men) with chronic, recurrent LBP (mean age 31.1 ± 12.9 years) were examined independently by 2 experienced physical therapists. Methods Training consisted of self-study of a procedure manual, a supervised practice of examination procedures and classification rules, and discussion. Subjects were examined independently by each therapist using a test-retest design. Each therapist assigned a LBP classification upon completion of the examination. Both therapists were blinded to the other therapist's findings. Main Outcome Measures Inter-tester reliability of therapists classifying the LBP problems was indexed by the percent agreement and kappa coefficient. Results Overall percent agreement on the classification assigned was 83% with kappa=0.75 (95% confidence interval=0.51-0.99; P Conclusion Inter-tester reliability of classification of patients with LBP when therapists use a standardized clinical examination based on the MSI classification system is substantial.

Case report.Selecting the most effective conservative treatment for knee pain continues to be a challenge. An understanding of the underlying movement system impairment that is thought to contribute to the knee pain may assist in determining the most effective treatment. Our case report describes the treatment and outcomes of a patient with the proposed movement system impairment (MSI) diagnosis of tibiofemoral rotation.The patient was a 50-year-old female with a 3-month history of left anteromedial knee pain. Her knee pain was aggravated with sitting, standing, and descending stairs. A standardized clinical examination was performed and the MSI diagnosis of tibiofemoral rotation was determined. The patient consistently reported an increase in pain with activities that produced abnormal motions or alignments of the lower extremity in the frontal and transverse planes. The patient was educated to modify symptom-provoking functional activities by restricting the abnormal motions and alignments of the lower extremity. Exercises were prescribed to address impairments of muscle length, muscle strength, and motor control proposed to contribute to the tibiofemoral rotation. Tape also was applied to the knee in an attempt to restrict tibiofemoral rotation.The patient reported a cessation of pain and an improvement in her functional activities that occurred with correction of her knee alignment and movement pattern. Pain intensity was 2/10 at 1 week. At 10 weeks, pain intensity was 0/10 and the patient reported no limitations in sitting, standing, or descending stairs. The patient's score on the activities of daily living scale increased from 73% at the initial visit to 86% at 10 weeks and 96% at 1 year after therapy was discontinued.This case report presented a patient with knee pain and an MSI diagnosis of tibiofemoral rotation. Diagnosis-specific treatment resulted in a cessation of the patient's pain and an improved ability to perform functional activities.

Use of the tibia as a lever to produce hip rotation for the purpose of measuring passive hip rotation range of motion (ROM) could result in inaccurate values if motion is allowed at the tibiofemoral joint (TFJ). The purpose of this study was to examine the effect of stabilizing the TFJ during measurement of prone hip rotation ROM in men and women. Passive hip rotation was measured in 20 unimpaired subjects (M = 10, F = 10) in two different stabilization conditions, with the TFJ stabilized and without the TFJ stabilized. A 2 x 2 analysis of variance was used to test for the effects of stabilization condition and gender on hip rotation measures. A significant interaction of gender and stabilization condition was obtained. Women displayed more hip rotation when the TFJ was not stabilized (M = 41.03 degrees , SD = 6.53 degrees ) than when the TFJ was stabilized (M = 35.05 degrees ; SD = 5.12 degrees ). Men displayed no difference in ROM between the two stabilization conditions (not stabilized: M = 39.07 degrees , SD = 4.87 degrees ; stabilized: M = 37.60 degrees , SD = 5.12 degrees ). To avoid measurement error of hip rotation ROM, use of the tibia as a lever to produce passive hip rotation should be used with caution, particularly in women.

It is unknown if low back pain (LBP) outcomes are enhanced by classification-specific treatment based on the Movement System Impairment classification system. The moderating effect of adherence to treatment also is unknown.Compare the efficacy of a classification-specific treatment (CS) and a non classification-specific (NCs) treatment and examine the moderating effect of adherence on outcomes.2 center, 2 parallel group, prospective, randomized, clinical trial.Participants with chronic LBP were classified and randomized. Self-report data was obtained at baseline, post-treatment, and 6 and 12 months post-treatment. The primary outcome was the modified Oswestry Disability Index (mODI; 0-100%). Treatment effect modifiers were exercise adherence and performance training adherence. An intention to treat approach and hierarchical linear modeling were used.47 people received CS treatment, 54 people received NCs treatment. Treatment groups did not differ in mODI scores (p 0.05). For both groups, scores improved with treatment (p 0.05), plateaued at 6 months (p 0.05), and minimally regressed at 12 months (p 0.05). Performance training adherence had a unique, independent effect on mODI scores above and beyond the effect of exercise adherence (p 0.05). There were no treatment group effects on the relationship between mODI scores and the two types of adherence (p 0.05).There were no differences in function between the two treatment groups (CS and NCs). In both treatment groups, people with chronic LBP displayed clinically important long-term improvements in function. When both forms of adherence were considered, the improvements were uniquely related to adherence to performance training.

The objective of this study was to develop comprehensive and reliable radiation-free methods to quantify femoral and acetabular morphology using magnetic resonance imaging (MRI). Thirty-two hips [16 subjects, 6 with intra-articular hip disorder (IAHD); 10 controls] were included. A 1.5-T magnetic resonance system was used to obtain three-dimensional fat-suppressed gradient-echo images at the pelvis and distal femora. After acquisition, pelvic images were post-processed to correct for coronal, axial and sagittal rotation. Measurements performed included acetabular version (AV), femoral version (FV), lateral center-edge angle (LCEA), femoral neck angle (FNA) and alpha angle (AA) at 3, 2, 1 and 12 a.m. Two experienced raters, a musculoskeletal radiologist and an orthopedic physical therapist, and a novice rater, a research assistant, completed reliability testing. Raters measured all hips twice with minimum 2 weeks between sessions. Intra-class Correlation Coefficients (ICCs) were used to determine rater reliability; standard error of measurements was reported to estimate the reasonable limits of the expected error in the different raters’ scores. Inter-rater reliability was good to excellent for all raters for AV, FV, FNA and LCEA (ICCs: 0.82–0.98); good to excellent between experienced raters (ICCs: 0.78–0.86) and poor to good between novice and experienced raters (ICCs: 0.23–0.78) for AA. Intra-rater reliability was good to excellent for all raters for AV, FV and FNA (ICCs: 0.93–0.99); for one experienced and novice rater for LCEA (ICCs: 0.84–0.89); moderate to excellent for the experienced raters for AA (ICCs: 0.72-0.89). Intra-rater reliability was poor for the second experienced rater for LCEA (ICC: 0.56), due to a single measurement error and for the novice rater for AA (ICCs: 0.17–0.38). We described MRI methods to comprehensively assess femoral and acetabular morphology. Measurements such as AV, FV and FNA and the LCEA can be made reliably by both experienced and novice raters; however, the AA measurement was reliable only among experienced raters.
