DESIGN Scoping review. LITERATURE SEARCH A computer-assisted literature search was conducted of the Medline, CINAHL, and Embase databases on June 17th, 2018. We used keywords related to FAI syndrome/labral tear and both open and arthroscopic surgical outcomes, and identified 169 studies, involving 16,675 patients. Prevalence of reported outcomes was calculated and verified by separate authors. STUDY SELECTION CRITERIA We included prospective or retrospective intervention or observational studies that included patients with a primary diagnosis of FAI syndrome and/or labral tear. DATA SYNTHESIS We calculated mean prevalence (± standard deviation) for continuous variables, where possible. All analyses were conducted in Excel 15.36 (2017 Microsoft Corporation by Impressa Systems, Santa Rosa, California). RESULTS Hip arthroscopy was the primary surgical procedure (76% of studies). The mean age of participants was 34.8±9.2 years, and they were followed for a mean of 27±15.3 months. Seventy-four (44%) studies discussed phases of rehabilitation. Forty-nine (29%) studies reported details for goals between phases; one in 3 studies described details for rehabilitation progression. Fewer than 1 in 10 studies reported sufficient detail to replicate the rehabilitation protocol. Weight bearing and range-of-motion restrictions were poorly reported and variable in duration. CONCLUSIONS Surgical outcome studies do not provide sufficient detail or consistency for practicing clinicians to replicate a postoperative rehabilitation protocol for patients with FAI syndrome/labral tear.

Differences in return to sport (RTS) and RTS at previous level (RTSP) after UCLI have not been differentiated. A computer-assisted literature search of PubMed, CINAHL, Embase, and SportDiscus databases using keywords related to RTS for UCLI was implemented. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used for study methodology. Quality assessment was conducted using a modified Downs and Black scale. A total of 22 retrospective, level 3b or 4, studies (n = 2289) qualified for analysis. Overall RTS proportion was 90% (95% confidence interval [CI], 86%-94%) and overall RTSP proportion was 79% (95% CI, 75%-84%), both with significant heterogeneity (P < .001, I = 74%-84%). RTS and RTSP proportions were 89% (95% CI, 83%-94%) and 78% (95% CI, 72%-83%) for Major League Baseball players, 91% (95% CI, 77%-99%) and 67% (95% CI, 52%-81%)...

To our knowledge, no studies in physical therapy have explored predictive criteria for positive professional performance (PPP) in one's career beyond an educational program. The two-fold purpose of this study was to analyze what traits were key indicators of PPP beyond one's academic preparation, with secondary goal to determine whether traits related to PPP could be mediated by academic preparation. A three-round Delphi survey targeted expert academicians with a specialization in programmatic performance and student success. Twenty-one Delphi respondents completed all survey rounds; identifying and determining consensus on traits associated with PPP. Respondents determined whether the traits could be influenced by programmatic training. The majority of traits identified with PPP were noncognitive and over half were considered modifiable through academic training. Trai...

To summarise the return to sport (RTS) rate for athletes after surgery for FAI syndrome. A computer-assisted search of MEDLINE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and EMBASE databases was performed using keywords related to RTS and RTS at preinjury level (RTS) of competition for FAI syndrome. The risk of bias in the included studies was assessed using the Methodological Index for Non-Randomized Studies scale. 35 studies (1634 athletes/1828 hips) qualified for analysis. Based on evidence of limited to moderate strength (level 3b to 4 studies), athletes return to sport at preinjury level post surgery for FAI syndrome at a rate of only 74% (67%-81%). Only 37% of studies reported RTS. The mean time from surgery to RTS was 7.0±2.6 months. The mean follow-up postsurgery was 28.1±15.5 months. Professional athletes returned to sport (p=0...

Consequently, hip imaging and surgery rates have grown rapidly.1 However, there is no strong evidence of improved clinical outcomes with arthroscopic interventions. Although imaging findings are only diagnostic for FAI syndrome when they exist together with clinical signs and symptoms , imaging remains the main criterion for FAI surgery.2 Most patients (71%) are willing to undergo surgery based solely on their physician’s recommendation.3 We question whether such reliance on imaging can be justified. Does it have risks (eg, radiation, downstream testing, costs) and may it lead to suboptimal management of hip-related groin pain? People with both large cam morphology and reduced hip internal rotation are 25 times more likely to develop future hip osteoarthritis (OA).4 While such high odd ratios cannot be ignored, many with such morphology do not develop …

Red flag screening is endorsed by most LBP clinical practice guidelines, despite a lack of support for their diagnostic capacity. We share four major reasons why red flag screening is not consistent with best practice in LBP management: (1) clinicians do not actually screen for red flags, they manage the findings; (2) red flag symptomology negates the utility of clinical findings; (3) the tests lack the negative likelihood ratio to serve as a screen; and (4) clinical practice guidelines do not include specific processes that aid decision-making. Based on these findings, we propose that clinicians consider: (1) the importance of watchful waiting; (2) the value-based care does not support clinical examination driven by red flag symptoms; and (3) the recognition that red flag symptoms may have a stronger relationship with prognosis than diagnosis.

A librarian-assisted computer search of Medline, CINAHL and Embase for studies related to criterion for FAIS surgery was used in this study. Inclusion criteria included studies with the primary purpose of surgery or surgical outcomes for treatment of FAIS with and without labral tear, and reporting criteria for FAIS surgery. Diagnostic imaging was a criterion for surgery in 92% of the included studies, with alpha angle the most frequently reported (68% of studies) criterion. Reporting of symptoms was a criterion for surgery in 75%, and special tests a criterion in 70% of studies. Range-of-motion limitations were only a required criterion in 30%, only 12% of studies required intra-articular injection and 44% of studies described previously failed treatment (non-surgical or physiotherapist-led rehabilitation) as a criterion fo...

The purpose of this case report is to describe the clinical reasoning process involved with the differential diagnosis and management of a 69 year-old male runner reporting a six month history of insidious onset of left sided low back and buttock pain of low to medium degree of irritability. The case presented describes the utilization of clinical reasoning by a clinician in fellowship training when a patient with atypical adverse neurodynamic dysfunction related to running was encountered. The patient's physical examination was relatively unremarkable. Assessment of the patient's subjective history, self-report measures [Oswestry Disability Index (ODI), global rating of change scale (GROC)], objective findings, and tests and measures led to a working diagnosis of atypical adverse peripheral neurodynamic dysfunction. The lumbar spine, sacroiliac joint, hip joint and lower extremity were ruled out by a comprehensive subjective and objective examination. The diagn...

The methodological quality of individual studies was assessed using the PEDro scale. After screening of titles, abstracts and full articles, eight articles were kept for examination. Three articles achieved a score of 10 of 11 total points; one achieved a score of 9; two articles scored 8; one article scored a 7 and the remaining article scored a 5. Three articles examined joint techniques for acute sprains and the remainder examined subacute/chronic ankle sprains. Outcome measures included were pain level, ankle range of motion, swelling, functional score, stabilometry and gait parameters. The majority of the articles only assessed these outcome measures immediately after treatment. No detrimental effects from the joint techniques were revealed in any of the studies reviewed. For acute ankle sprains, manual joint mobilisation diminished pain and increased dorsiflexion range of motion. For treatment of subacute/chronic lateral ankle sprains, these techniques improved ankle range-of-motion, decreased pain and improved function.

No previous study has identified deficits in pelvic, hip or knee motion as potential contributing factors to MSP. The purpose of this study was to investigate the differences in kinematics during running between uninjured athletes and those with MSP. Secondary analyses investigated differences in limbs between groups and differences between sexes. This case-control study investigated fourteen runners aged 18-40 years old with a history of unilateral MSP and fourteen runner controls. Three dimensional lower quarter kinematics were captured as runners ran on a treadmill. Specifically, peak hip internal rotation (IR), frontal plane pelvic tilt (PT) excursion, and knee flexion were examined. Groups were similar in age, mass, height, and training mileage. Subjects with a history of MSP demonstrated significantly greater frontal plane PT (P = 0.002, Effect size = 0.55) and peak hip IR (P = 0.004, Effect si...

Traditionally, eccentric exercise has been used as a regular component of strength training. However, in recent years, eccentric exercise has been used in rehabilitation to manage a host of conditions. Of note, there is evidence in the literature supporting eccentric exercise for the rehabilitation of tendinopathies, muscle strains, and in anterior cruciate ligament (ACL) rehabilitation. The purpose of this Clinical Commentary is to discuss the physiologic mechanism of eccentric exercise as well as to review the literature regarding the utilization of eccentric training during rehabilitation. A secondary purpose of this commentary is to provide the reader with a framework for the implementation of eccentric training during rehabilitation of tendinopathies, muscle strains, and after ACL reconstruction.

The purpos e of the present study was to perform a systematic review and meta-analysis of the literature, to determine the effectiveness and fidelity of studies using MT techniques in individuals with knee OA. Relevant studies were assessed for inclusion. Effectiveness was measured using effect sizes, and methodological bias and treatment fidelity were both explored. Effect sizes were calculated using standardized mean differences (SMD) based on pooled data depending on statistical and clinical heterogeneity, as well as risk of bias. The search captured 2,969 studies; after screening, 12 were included. Four had a low risk of bias and high treatment fidelity. For self-reported function, comparing MT with no treatment resulted in a large effect size (standardized mean difference [SMD] 0.84), as did adding MT to a comparator treatment (SMD 0.78). A significant difference was found for pain when adding MT to a comparator treatment (SMD 0.73). The findings in the present meta-analytical review support the use of MT versus a number of different comparators for improvement in self-reported knee function. Lesser support is present for pain reduction, and no endorsement of functional performance can be made at this time.

The objective of the present study was to identify predictive characteristics related to patients with knee impairments who had a high risk of a bad prognosis (exceptional non-responders) as well as those who were at low risk of a bad prognosis (exceptional responders). A cohort of 4,837 patients with knee pain seen for physical therapy was retrospective analysed using univariate and multivariate multinomial regression analyses. Modelling was used to identify characteristics associated with those who were exceptional responders and those who were exceptional non-responders. Exceptional non-responders were significantly associated with older age, female gender, longer duration of symptoms, surgical history, lower functional status at baseline and a payer type. Exceptional responders were significantly associated with younger age, no previous surgical history, higher...

This study was conducted to examine the relationship between timed performance on functional tasks of daily living and age, knee isometric strength, and peak aerobic capacity in a group of individuals with DS. This was a cross-sectional study involving 35 individuals (27 +/- 7.5 yr) with DS. Participants completed an isometric test of knee extensor and flexor strength, an individualized exercise test to measure peak aerobic capacity, and three timed functional tasks of daily living, which included chair rise, gait speed, and stair ascent and descent. Multiple regression analyses were performed to examine the relationship between timed task performance and age, knee isometric strength, and peak aerobic capacity. The multiple regression models explained 11-29% of the variance in timed task performance. Knee extensor strength was the most influential variable in predicting timed task performance (squared semipartial correlation coefficient [sr2] = 0.11-0.20), followed by aerobic capacity (sr2 = 0.10-0.14). Age was not a significant predictor of timed task performance. These findings suggest that physical fitness (defined here as aerobic capacity and knee extensor strength) limits the ability of adults with DS to perform functional tasks of daily living. Randomized controlled trials should be performed to test the probable causal relationship between exercises designed to improve physical fitness and functional tasks of daily living.

Lumbar discectomy is a common surgical procedure to alleviate pain and disability in athletes. We systematically reviewed the current clinical evidence regarding athlete return to sport (RTS) following lumbar discectomy compared to conservative treatment. A computer-assisted literature search of MEDLINE, CINAHL, Web of Science, PEDro, OVID and PubMed databases (from inception to August 2015) was utilised using keywords related to lumbar disc herniation and surgery. The design of this systematic review was developed using the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Methodological quality of individual studies was assessed using the Downs and Black scale (0-16 points). The search strategy revealed 14 articles. Downs and Black quality scores were generally low with no articles in this review earning a high-quality rating, only 5 articles earning a moderate quality rating and 9 of the 14 articles earning a low-quality rating. The pooled RTS for surgical intervention of all included studies was 81% (95% CI 76% to 86%) with significant heterogeneity (I(2)=63.4%, p&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.001) although pooled estimates report only 59% RTS at same level. Pooled analysis showed no difference in RTS rate between surgical (84% (95% CI 77% to 90%)) and conservative intervention (76% (95% CI 56% to 92%); p=0.33). Studies comparing surgical versus conservative treatment found no significant difference between groups regarding RTS. Not all athletes that RTS return at the level of participation they performed at prior to surgery. Owing to the heterogeneity and low methodological quality of included studies, rates of RTS cannot be accurately determined.

A computer-assisted literature search of MEDLINE, CINHAL, EMBASE, OVID and Physiotherapy Evidence Database (PEDro) (January 1966 to March 2013) was used with the following keywords alone and in combination &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;ankle&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;, &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;sprain&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;, &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;injuries&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;, &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;lateral&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;, &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;manual therapy&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;, and &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;joint mobilisation&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;. The methodological quality of individual studies was assessed using the PEDro scale. After screening of titles, abstracts and full articles, eight articles were kept for examination. Three articles achieved a score of 10 of 11 total points; one achieved a score of 9; two articles scored 8; one article scored a 7 and the remaining article scored a 5. Three articles examined joint techniques for acute sprains and the remainder examined subacute/chronic ankle sprains. Outcome measures included were pain level, ankle range of motion, swelling, functional score, stabilometry and gait parameters. The majority of the articles only assessed these outcome measures immediately after treatment. No detrimental effects from the joint techniques were revealed in any of the studies reviewed. For acute ankle sprains, manual joint mobilisation diminished pain and increased dorsiflexion range of motion. For treatment of subacute/chronic lateral ankle sprains, these techniques improved ankle range-of-motion, decreased pain and improved function.

No previous study has identified deficits in pelvic, hip or knee motion as potential contributing factors to MSP. The purpose of this study was to investigate the differences in kinematics during running between uninjured athletes and those with MSP. Secondary analyses investigated differences in limbs between groups and differences between sexes. This case-control study investigated fourteen runners aged 18-40 years old with a history of unilateral MSP and fourteen runner controls. Three dimensional lower quarter kinematics were captured as runners ran on a treadmill. Specifically, peak hip internal rotation (IR), frontal plane pelvic tilt (PT) excursion, and knee flexion were examined. Groups were similar in age, mass, height, and training mileage. Subjects with a history of MSP demonstrated significantly greater frontal plane PT (P = 0.002, Effect size = 0.55) and peak hip IR (P = 0.004, Effect si...

Traditionally, eccentric exercise has been used as a regular component of strength training. However, in recent years, eccentric exercise has been used in rehabilitation to manage a host of conditions. Of note, there is evidence in the literature supporting eccentric exercise for the rehabilitation of tendinopathies, muscle strains, and in anterior cruciate ligament (ACL) rehabilitation. The purpose of this Clinical Commentary is to discuss the physiologic mechanism of eccentric exercise as well as to review the literature regarding the utilization of eccentric training during rehabilitation. A secondary purpose of this commentary is to provide the reader with a framework for the implementation of eccentric training during rehabilitation of tendinopathies, muscle strains, and after ACL reconstruction.

The purpos e of the present study was to perform a systematic review and meta-analysis of the literature, to determine the effectiveness and fidelity of studies using MT techniques in individuals with knee OA. Relevant studies were assessed for inclusion. Effectiveness was measured using effect sizes, and methodological bias and treatment fidelity were both explored. Effect sizes were calculated using standardized mean differences (SMD) based on pooled data depending on statistical and clinical heterogeneity, as well as risk of bias. The search captured 2,969 studies; after screening, 12 were included. Four had a low risk of bias and high treatment fidelity. For self-reported function, comparing MT with no treatment resulted in a large effect size (standardized mean difference [SMD] 0.84), as did adding MT to a comparator treatment (SMD 0.78). A significant difference was found for pain when adding MT to a comparator treatment (SMD 0.73). The findings in the present meta-analytical review support the use of MT versus a number of different comparators for improvement in self-reported knee function. Lesser support is present for pain reduction, and no endorsement of functional performance can be made at this time.

The objective of the present study was to identify predictive characteristics related to patients with knee impairments who had a high risk of a bad prognosis (exceptional non-responders) as well as those who were at low risk of a bad prognosis (exceptional responders). A cohort of 4,837 patients with knee pain seen for physical therapy was retrospective analysed using univariate and multivariate multinomial regression analyses. Modelling was used to identify characteristics associated with those who were exceptional responders and those who were exceptional non-responders. Exceptional non-responders were significantly associated with older age, female gender, longer duration of symptoms, surgical history, lower functional status at baseline and a payer type. Exceptional responders were significantly associated with younger age, no previous surgical history, higher...

This study was conducted to examine the relationship between timed performance on functional tasks of daily living and age, knee isometric strength, and peak aerobic capacity in a group of individuals with DS. This was a cross-sectional study involving 35 individuals (27 +/- 7.5 yr) with DS. Participants completed an isometric test of knee extensor and flexor strength, an individualized exercise test to measure peak aerobic capacity, and three timed functional tasks of daily living, which included chair rise, gait speed, and stair ascent and descent. Multiple regression analyses were performed to examine the relationship between timed task performance and age, knee isometric strength, and peak aerobic capacity. The multiple regression models explained 11-29% of the variance in timed task performance. Knee extensor strength was the most influential variable in predicting timed task performance (squared semipartial correlation coefficient [sr2] = 0.11-0.20), followed by aerobic capacity (sr2 = 0.10-0.14). Age was not a significant predictor of timed task performance. These findings suggest that physical fitness (defined here as aerobic capacity and knee extensor strength) limits the ability of adults with DS to perform functional tasks of daily living. Randomized controlled trials should be performed to test the probable causal relationship between exercises designed to improve physical fitness and functional tasks of daily living.

Lumbar discectomy is a common surgical procedure to alleviate pain and disability in athletes. We systematically reviewed the current clinical evidence regarding athlete return to sport (RTS) following lumbar discectomy compared to conservative treatment. A computer-assisted literature search of MEDLINE, CINAHL, Web of Science, PEDro, OVID and PubMed databases (from inception to August 2015) was utilised using keywords related to lumbar disc herniation and surgery. The design of this systematic review was developed using the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Methodological quality of individual studies was assessed using the Downs and Black scale (0-16 points). The search strategy revealed 14 articles. Downs and Black quality scores were generally low with no articles in this review earning a high-quality rating, only 5 articles earning a moderate quality rating and 9 of the 14 articles earning a low-quality rating. The pooled RTS for surgical intervention of all included studies was 81% (95% CI 76% to 86%) with significant heterogeneity (I(2)=63.4%, p&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.001) although pooled estimates report only 59% RTS at same level. Pooled analysis showed no difference in RTS rate between surgical (84% (95% CI 77% to 90%)) and conservative intervention (76% (95% CI 56% to 92%); p=0.33). Studies comparing surgical versus conservative treatment found no significant difference between groups regarding RTS. Not all athletes that RTS return at the level of participation they performed at prior to surgery. Owing to the heterogeneity and low methodological quality of included studies, rates of RTS cannot be accurately determined.
