Hoglund LT, Hulcher TA, Amabile AH. Males with patellofemoral pain have altered movements during step-down and single-leg squatting tasks compared to asymptomatic males: A cross-sectional study. Health Sci Rep 2024; 7:e2193. [PMID: 38868539 PMCID: PMC11168284 DOI: 10.1002/hsr2.2193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 04/18/2024] [Accepted: 05/30/2024] [Indexed: 06/14/2024] Open
Abstract
Background and Aims Patellofemoral pain (PFP) is common in males, causing reduced physical activity and chronic pain. One proposed cause of PFP is aberrant biomechanics during tasks loading the patellofemoral joint. Consistent evidence exists for females with PFP, but it is uncertain if males with PFP have altered biomechanics. This study investigated the kinematics of males with PFP compared to pain-free males during forward step-down (StDn) and single-leg squat (SLSq). Methods A cross-sectional study including 40 males aged 20-39 years (28.28 ± 5.46) was conducted (20 PFP, 20 pain-free). Participants performed StDn and SLSq while motion was captured with a video-based motion capture system (Motion Analysis Corporation). Triplanar peak angles and angular ranges of motion (ROM) of the trunk, pelvis, and weight-bearing hip, knee, and ankle were dependent variables. Mixed-model ANOVA tests were used to determine the presence of significant interactions and main effects of group and task. Results Males with PFP had significantly lower peak knee adduction angles compared to pain-free males (p = 0.01). Significant group x task interactions were found for hip and pelvis ROM (p < 0.05). PFP participants had increased hip and pelvis ROM during StDn in the frontal and transverse planes but reduced or nearly equal ROM for these variables during SLSq. Peak hip adduction, hip internal rotation, contralateral pelvic drop and anterior tilt, trunk flexion, and ankle dorsiflexion were greater during StDn compared to SLSq (p < 0.05). ROM of the hip, pelvis, trunk, and ankle were greater during StDn compared to SLSq (p < 0.05). Conclusion Males with PFP had reduced peak knee adduction angles in StDn and SLSq. Males with PFP demonstrated increased hip and pelvis ROM during StDn versus SLSq, particularly in the frontal and transverse planes. Clinicians should consider StDn as a clinical test since aberrant movement may be easier to detect than in SLSq.

Arch Phys Med Rehabil 2024; 105:217-226. [PMID: 37717685 DOI: 10.1016/j.apmr.2023.08.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Revised: 08/03/2023] [Accepted: 08/29/2023] [Indexed: 09/19/2023]
Abstract
OBJECTIVE To investigate the effect of adding education to trunk and hip exercises in patients with patellofemoral pain (PFP). DESIGN A randomized controlled trial. SETTING Research laboratory. PARTICIPANTS Sixty patients with PFP (N=60) were randomly assigned to either an experimental group (education followed by trunk and hip exercises, n=30) or a control group (trunk and hip exercises, n=30). INTERVENTIONS Both groups received 8 weeks of trunk and hip exercises, while patients in the experimental group participated in 3 prior education sessions. MAIN OUTCOME MEASURES The primary outcome was pain; secondary outcomes were pain catastrophizing, kinesiophobia, function, and muscle strength. Outcomes were assessed at baseline, after 8 weeks (post-intervention), and 3 months post-intervention (follow-up). RESULTS No significant between-group differences were observed for pain outcome post-intervention. The experimental group showed superiority over the control group in the improvement of pain catastrophizing (mean difference: -2.32; 95% confidence interval [CI] -1.059 to 0.028) and kinesiophobia (mean difference: -3.56; 95% CI -1.067 to -0.035) at post-intervention. In the experimental group, improvements were maintained at follow-up assessment for all outcomes, except muscle strength. CONCLUSION Adding education to trunk and hip exercises was associated with greater improvements in psychological outcomes than trunk and hip exercises alone after the intervention. Education can be incorporated when designing trunk and hip exercises for patients with PFP.

Abstract
BACKGROUND Impaired knee extensor neuromuscular function has been frequently observed in individuals with patellofemoral pain (PFP); however, few researchers have aimed to understand the influence of sex on knee extensor neuromuscular function in this pathological population. The authors aimed to determine whether there are differences in knee extensor neuromuscular function between sexes in individuals with and without PFP. HYPOTHESIS Women with PFP would exhibit greater deficits in knee extensor neuromuscular function than men with PFP, compared with sex-matched individuals without PFP. STUDY DESIGN Cross-sectional, case-control study. LEVEL OF EVIDENCE Level 4. METHODS A total of 110 individuals were classified into 4 groups: women with PFP (n = 25); men with PFP (n = 30); women without PFP (n = 25); and men without PFP (n = 30). Knee extensor strength (isometric peak torque [PT]), activation (central activation ratio), early, late, and total phase rate of torque development (RTD0-100, RTD100-200, and RTD20-80%), and endurance (isokinetic average PT) were assessed using an isokinetic dynamometer. Group differences were assessed using a 2-way multivariate analysis of variance (sex by PFP). RESULTS Both women and men with PFP exhibited lower knee extensor strength, activation, early, late, and total phase RTD, and endurance versus sex-matched individuals without PFP (P < 0.05 for all comparisons). Women with PFP exhibited lower early phase (7.91 ± 2.02 versus 9.78 ± 2.43 N·m/s/kg; P < 0.01; Cohen d = 0.83), late phase (5.34 ± 1.02 versus 7.28±2.28 N·m/s/kg; P < 0.01; Cohen d = 1.37), and total phase (7.40 ± 2.57 versus 8.72 ± 2.57 N·m/s/kg; P = 0.03; Cohen d = 0.51) RTD than men with PFP. CONCLUSION Compared with sex-matched pain-free individuals, women with PFP displayed lower RTD than men with PFP. Clinicians should note that among individuals with PFP, women are more likely to experience a greater impairment in their knee extensor torque-generating capacity than men. CLINICAL RELEVANCE Additional treatment strategies that effectively improve the ability to rapidly generate torque should be developed and implemented, especially when treating women with PFP.

Abstract
Objectives To determine the feasibility of conducting a large-scale randomised controlled trial on the efficacy of flat, flexible school footwear versus traditional school footwear in adolescents (aged 12-18 years) with patellofemoral pain (PFP). Methods Adolescents with PFP were recruited for this study. Participants were randomised to wear either a (1) flat, flexible school shoe or (2) a traditional school shoe. Participants wore the shoes as per school requirements for 12 weeks. Feasibility was assessed by (1) adherence to allocated shoe wear of ≥75% of total weekly school shoe wear time (recorded through weekly log sheets), (2) a recruitment rate of one participant per fortnight and (3) a dropout rate of ≤ 20%. Descriptive statistics were used for feasibility outcomes. Results 24 adolescents (15 men, 9 women, mean (SD) age 14.3 (1.7) years) participated in this study. Two participants (8%) were lost to follow-up. The recruitment rate was 1.7 participants per fortnight. 11 of 12 participants (91%) in the flat flexible shoe group and 9 of 10 participants (90%) in the traditional shoe group met the minimum adherence for shoe wear. Mean weekly shoe wear was 20 (7.6) and 21 (4.5) hours per week in the flat, flexible, and traditional shoe groups, respectively. Conclusion Our results indicate that progression to a full-scale randomised controlled trial is feasible based on the current protocol. A full-scale randomised controlled trial powered to detect estimates of treatment efficacy using flat, flexible school shoes versus traditional school shoes is warranted and will guide evidence-based management of adolescent PFP.

Abstract
OBJECTIVE: To test whether a series of brief, psychologically informed educational videos added to physical therapy improved function among adolescents with patellofemoral pain. The secondary aims were to assess pain and psychological beliefs. DESIGN: A double-blinded randomized controlled trial. METHODS: Sixty-eight adolescents with patellofemoral pain were randomly assigned to view brief, psychologically informed videos (n = 34) or control videos (n = 34) in addition to usual care physical therapy. The psychologically informed videos targeted fear-avoidance beliefs, kinesiophobia, and pain catastrophizing. The control videos conveyed basic anatomy, biomedical factors, and lower extremity mechanics. Outcomes were assessed at baseline, 3 weeks, 6 weeks (primary end point), and 3 months. The primary outcome was change in the Anterior Knee Pain Scale. Secondary outcomes were changes in Numeric Pain-Rating Scale and psychological beliefs (Modified Fear-Avoidance Beliefs Questionnaire-Physical Activity, Tampa Kinesiophobia Scale-11, and Pain Catastrophizing Scale-Child). RESULTS: Adolescents in the psychologically informed group experienced significantly greater improvements in function (Anterior Knee Pain Scale mean difference = 8 points; 95% CI: 2.2, 13.2; P = .01) and pain (Numeric Pain-Rating Scale mean difference = 1.2 points; 95% CI: 0.1, 2.4; P = .04) at 6 weeks compared to the control group. The psychologically informed group had significantly greater reductions in psychological beliefs over time than the control group (P≤.001; partial η2 = 0.32). CONCLUSION: Incorporating psychologically informed education into physical therapy care improved function, pain, and psychological beliefs to a greater extent than the control group.

Abstract
OBJECTIVE: We aimed to appraise the construct validity, reliability, responsiveness, and interpretability of patient-reported outcome measures (PROMs) used to assess function and pain in adults and adolescents with patellofemoral pain (PFP). DESIGN: Systematic review of measurement properties LITERATURE SEARCH: We searched the PubMed, CINAHL, Scopus, SPORTDiscus, and Cochrane Library databases from inception to January 6, 2022. STUDY SELECTION CRITERIA: We included studies that assessed the measurement properties of English-language PROMs for PFP and their cultural adaptations and translations. DATA SYNTHESIS: Using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology, we determined overall ratings and quality of evidence for construct validity, internal consistency, reliability, measurement error, and responsiveness. We extracted data related to interpretability for clinical use. RESULTS: After screening 7066 titles, 61 studies for 33 PROMs were included. Only 2 PROMs had evidence of "sufficient" or "indeterminate" quality for all measurement properties. The Knee injury and Osteoarthritis Outcome Score patellofemoral subscale (KOOS-PF) had "low" to "high" quality evidence for a rating of "sufficient" for 4 measurement properties. The Lower Extremity Functional Scale (LEFS) had very low-quality evidence for a "sufficient" rating for 4 measurement properties. The KOOS-PF and LEFS were rated "indeterminate" for structural validity and internal consistency. The KOOS-PF had the best interpretability with reported minimal important change and 0% ceiling and floor effects. No studies examined cross-cultural validity. CONCLUSION: The KOOS-PF and LEFS had the strongest measurement properties among PROMs used for PFP. More research is needed, particularly regarding structural validity and interpretability of PROMs. J Orthop Sports Phys Ther 2023;53(8):1-20. Epub: 20 June 2023. doi:10.2519/jospt.2023.11730.

ADAPTations to low load blood flow restriction exercise versus conventional heavier load resistance exercise in UK military personnel with persistent knee pain: protocol for the ADAPT study, a multi-centre randomized controlled trial. BMC Musculoskelet Disord 2023; 24:580. [PMID: 37461024 DOI: 10.1186/s12891-023-06693-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Accepted: 07/04/2023] [Indexed: 07/20/2023] Open
Abstract
BACKGROUND Muscle atrophy, muscle weakness and localised pain are commonly reported following musculoskeletal injury (MSKI). To mitigate this risk and prepare individuals to return to sport or physically demanding occupations, resistance training (RT) is considered a vital component of rehabilitation. However, to elicit adaptations in muscle strength, exercise guidelines recommend lifting loads ≥ 70% of an individual's one repetition maximum (1-RM). Unfortunately, individuals with persistent knee pain are often unable to tolerate such high loads and this may negatively impact the duration and extent of their recovery. Low load blood flow restriction (LL-BFR) is an alternative RT technique that has demonstrated improvements in muscle strength, hypertrophy, and pain in the absence of high mechanical loading. However, the effectiveness of high-frequency LL-BFR in a residential rehabilitation environment remains unclear. This study will compare the efficacy of high frequency LL-BFR to 'conventional' heavier load resistance training (HL-RT) on measures of physical function and pain in adults with persistent knee pain. METHODS This is a multicentre randomised controlled trial (RCT) of 150 UK service personnel (aged 18-55) admitted for a 3-week residential rehabilitation course with persistent knee pain. Participants will be randomised to receive: a) LL-BFR delivered twice daily at 20% 1-RM or b) HL-RT three-times per week at 70% 1-RM. Outcomes will be recorded at baseline (T1), course discharge (T2) and at three-months following course (T3). The primary outcome will be the lower extremity functional scale (LEFS) at T2. Secondary outcomes will include patient reported perceptions of pain, physical and occupational function and objective measures of muscle strength and neuromuscular performance. Additional biomechanical and physiological mechanisms underpinning both RT interventions will also be investigated as part of a nested mechanistic study. DISCUSSION LL-BFR is a rehabilitation modality that has the potential to induce positive clinical adaptations in the absence of high mechanical loads and therefore could be considered a treatment option for patients suffering significant functional deficits who are unable to tolerate heavy load RT. Consequently, results from this study will have a direct clinical application to healthcare service providers and patients involved in the rehabilitation of physically active adults suffering MSKI.

Abstract
BACKGROUND The study aimed to assess the reliability, validity, and responsiveness of the Polish version of Knee Outcome Survey Activities of the Daily Living Scale (KOS-ADLS) in a group of patients after arthroscopic reconstruction of the anterior cruciate ligament (ACL). METHODS The study was a longitudinal study with repeated measures. One hundred and twelve subjects who qualified for arthroscopic ACL reconstruction (mean age = 31.8 years) were initially enrolled in this study. The Polish version of KOS-ADLS and Short Form-36 v. 2.0 (SF-36) were used. RESULTS The Polish version of KOS-ADLS in subjects after ACL rupture demonstrated excellent internal consistency (Cronbach's alpha for KOS-ADLS- total = 0.91), and test-retest reliability using the intraclass correlation coefficient (ICC-total = 0.98). The standard error of measurement (SEM) value was 0.81 and the minimal detectable change (MDC) was 2.23 for KOS-ADLS-total. The validity analysis showed a moderate and low correlation between KOS-ADLS and different domains of SF-36 from r = 0.354 between KOS-ADLS activity and the physical component scale (PCS) of SF-36: to r = 0.206 between KOS-ADLS activity and the mental component scale (MCS) of SF-36. CONCLUSIONS The Polish version of KOS-ADLS turned out to be a reliable, valid and responsive self-reported outcome measure, allowing for the self-assessment of symptoms and function related to the knee joint impairment after ACL reconstruction. Therefore, the scale can be applied in clinical practice and research.

Abstract
BACKGROUND Patellofemoral pain (PFP) is characterized by anterior knee, which intensifies during functional activities that require the eccentric action of the quadriceps muscle, specially. In ths way, quantitatively measurable functional tests that simulate these activities should be included in the physical therapy evaluation. OBJECTIVE To identify which functional tests are most indicated for the evaluation of women with PFD. METHOD This study evaluated 100 young women (50 with PFP), during the execution of the following functional performance tests: Triple hop, Vertical Jump, Single leg squat, Step Down, YBalance tests, Lunge test and running. Dynamic valgus was also assessed in the tests. The isometric muscle strength of the following muscle groups: hip abductors, extensors and lateral rotators, knee extensors, evertors, and plantar flexors were evaluated. Functional Perception were evaluated by Anterior Knee Pain Scale and Activities of Daily Living Scale. RESULTS PFP group showed lower performance during the Y-Balance, triple hop, vertical jump tests and running. Was observed an increase in dynamic valgus during Triple Hop, Vertical Jump tests and running in PFP group, besides a poorer perception of function. For all lower limb muscle groups, the PFP group showed a reduction in peak isometric force. CONCLUSION The YBalance, triple hop, vertical jump tests, and running should be included in the physical therapy evaluation, in addition to aspects of lower limb muscle strength.

Adding neuromuscular training to a strengthening program did not produce additional improvement in clinical or kinematic outcomes in women with patellofemoral pain: A blinded randomised controlled trial. Musculoskelet Sci Pract 2023; 63:102720.

Abstract
BACKGROUND Patellofemoral pain (PFP) is a knee pain condition with multifactorial aetiology, twice common in women. The recommended conservative treatment is based on strengthening of the core, hip, and knee musculatures. Addition of neuromuscular training to a strengthening protocol might provide further benefits on pain, function, and kinematics in PFP individuals. However, evidence for the effectiveness of this protocol is lacking. OBJECTIVE To investigate whether adding neuromuscular training to strengthening program could provide any additional improvements of pain, function, and kinematics in PFP women. METHODS 71 PFP women were randomly into two groups and submitted to different interventions for 12 weeks. The strengthening group (SG) performed strengthening exercises for the trunk, hip, and knee muscles, while the neuromuscular training group (NMTG) performed the same exercises as SG, plus neuromuscular training from the 4th week onwards. The primary outcomes were pain intensity, function, and 2-D kinematics of the trunk and lower limb. The secondary outcomes were isometric muscle strength and patient satisfaction level. All outcomes were evaluated at 12 weeks, immediately post-treatment. RESULTS At 12 weeks, there was no evidence of between-group differences for any outcome, but both interventions provided clinically significant improvements for pain intensity (SG: mean difference -3.9, 95% confidence interval [CI] -5.0, -2.9; NMTG: mean difference -3.1, 95% CI -4.1, -2.0) and function (SG: mean difference 15.3, 95% CI 11.5, 19.2; NMTG: mean difference 16.9, 95% CI 13.2, 20.7). CONCLUSION Neuromuscular training did not produce any additional benefits for pain, function, or kinematics at 12 weeks of treatment.

Translation, cross-cultural adaptation and validation of the Italian version of the knee outcome survey - activities of daily living scale. Musculoskelet Sci Pract 2023; 63:102716. [PMID: 36630780 DOI: 10.1016/j.msksp.2023.102716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 12/30/2022] [Accepted: 01/02/2023] [Indexed: 01/05/2023]
Abstract
PURPOSE The Knee Outcome Survey - Activities of Daily Living Scale (KOS-ADLS) is a joint-specific questionnaire measuring symptoms and functional limitations experienced by individuals with painful knee disorders. The original version of the KOS-ADLS has been shown to be reliable, valid and responsive to change. The purpose of this study was to perform a translation and cross-cultural adaptation of the KOS-ADLS into Italian and to assess its reliability and validity. METHODS In accordance with standard procedures, the original version of the KOS-ADLS was translated and cross-culturally adapted into Italian (KOS-ADLS-I). Then, the KOS-ADLS-I was administered to 150 patients with knee disorders. A subsample of patients compiled the KOS-ADLS-I again after five/seven days later to evaluate test-retest reliability. Symptoms and function-oriented questionnaires were also completed to evaluate construct validity. Structural validity (Explanatory Factor Analysis [EFA]), internal consistency (Cronbach's alpha), test-retest reliability (Intraclass Correlation Coefficient [ICC]), measurement error (Standard Error of the Measurement [SEM], Minimal Detectable Change [MDC]), and construct validity (hypothesis testing) were assessed. RESULTS The cross-cultural adaptation procedure revealed no major problems. EFA revealed a unidimensional structure. Internal consistency was high (Cronbach's alpha = 0.976) and the test-retest reliability was excellent (ICC = 0.990, 95%CI: 0.980-0.995) with low measurement error (SEM = 2.6 points; MDC = 7.1 points). The construct validity resulted to be satisfactory, as 100% a-priori hypothesis were met. CONCLUSIONS The KOS-ADLS-I is a reliable and valid questionnaire for the assessment of symptoms and functional limitations in individuals with musculoskeletal knee disorders and it can be used in clinical practice and research.

Abstract
BACKGROUND Even though literature indicates presence of weak hip abductors and lateral rotators' in Patellofemoral Pain (PFP), studies evaluating the effect of hip abductors and lateral rotators strengthening to improve knee function and quality of life in PFP are limited. OBJECTIVE This study systematically reviews and meta-analyzes the best evidence on the therapeutic value of strengthening hip abductors and lateral rotators muscles for treating PFP with a presumptive hypothesis that strengthening hip muscles stabilizes the patellofemoral joint, relieves pain, and enhances knee functions. METHOD Medline, EMBASE, CINAHL, PEDro and PubMed Central databases were searched between January 1994 and September 2019 using the PICOS tool. The methodological quality of the selected studies were appraised individually using the 20-item McMaster Critical Review Form for Quantitative Studies. Supplemental quality appraisal of randomized controlled clinical trials performed using the Cochrane Collaboration's 'Risk of bias' quality criteria. Data on patient population demographics, interventions, duration of intervention, and outcome measures were extracted and summarized in evidence tables and descriptive analysis. Meta-analyses under both fixed and random-effects models determined pooled effects size from appropriate RCTs. RESULTS All fourteen studies demonstrated that hip muscle strengthening improved pain and knee function. All RCTs, except one, demonstrated that hip muscle strengthening is superior to quadriceps strengthening. Of the five RCTs assessing the additional effect of hip-quad versus quadriceps strengthening, four suggested that hip-quad strengthening is superior to standard quadriceps strengthening alone to improve PFP and knee function. CONCLUSION In adult patients with PFP, strengthening hip abductors and lateral rotators' have beneficial therapeutic effects than the conventional quadriceps exercises in improving knee pain and function both in the short- and long term. However, the present review data can be used to develop a standardized hip-quad protocol in the future.

Abstract
OBJECTIVE: To assess the content validity and feasibility of patient-reported outcome measures (PROMs) used to assess pain and function in adults and adolescents with patellofemoral pain (PFP). DESIGN: Systematic review. LITERATURE SEARCH: We searched the databases PubMed, CINAHL, Scopus, SPORTDiscus, and the Cochrane Library from inception to January 6, 2022. STUDY SELECTION CRITERIA: We included studies that described the development or evaluation of the content validity of English-language PROMs for PFP, as well as their translations and cultural adaptations to different languages. DATA SYNTHESIS: Using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology, we determined overall ratings and quality of evidence for the relevance, comprehensiveness, and comprehensibility of PROMs. We extracted data related to feasibility for clinical use (eg, administration time and scoring ease). RESULTS: Forty-three studies for 33 PROMs were included. The overall quality of most studies was "inadequate" due to failure to engage stakeholders and/or ensure adherence to rigorous qualitative research procedures. Of all PROMs evaluated, the Knee injury and Osteoarthritis Outcome Score-Patellofemoral subscale (KOOS-PF), was the only PROM with sufficient content validity components. Quality of evidence for content validity of the KOOS-PF was low. Most PROMs were rated feasible for clinical and research purposes. CONCLUSION: Most PROMs used to measure pain and function in patients with PFP have inadequate content validity. The KOOS-PF had the highest overall content validity. We recommend the KOOS-PF for evaluating pain and function (in research and clinical practice) in adults and adolescents with PFP. J Orthop Sports Phys Ther 2023;53(1):23-39.

Abstract
Background Plantar fasciitis develops as a consequence of irritation of the plantar fascia, which is responsible for supporting the arches and absorbing shock. Multiple factors can contribute to plantar fasciitis, but the most common factor is overuse stress. The classical presentation is a sharp pain that is felt at the plantar aponeurosis (near the area of its insertion on the medial process of the calcaneal tuberosity), and it is possible to find a heel spur (osteophyte) in some cases. Most treatments for plantar fasciitis are ineffective and unsatisfactory for patients. Objective To estimate the prevalence and assess risk factors for plantar fasciitis among the population of the Jazan region. Methods A cross-sectional online survey was conducted on the population of the Jazan region. An online Google form questionnaire was prepared and distributed to the study population. Data was then entered and analyzed using IBM SPSS (Statistical Package for the Social Sciences) Statistics, version 21.0. Results A total of 695 participants were enrolled in the study. Out of that, 350 (50.4%) of the participants were males, while 345 (49.6%) were females. About the age of the participants, 507 (72.9%) were younger than 40 years of age. Participants with hypertension were 43 (6.2%), and 37 (5.3%) participants had diabetes. In terms of occupation, 120 (17.3%) worked in healthcare, 187 (26.9%) taught, and 43 (6.2%) served in the military. A great quantity of standing or walking was necessary for the jobs for 127 people (18.3%), while moderate amounts were recorded for 273 people (39.3%). The most commonly reported lower limb conditions were: pes planus (low arches) in 26 (3.7%) participants; and weakness of the gastrocnemius, soleus, and intrinsic foot muscles. The most commonly reported exercises were walking for 499 (71.8%) participants and jogging for 97 (14%) participants. The prevalence of plantar fasciitis was found to be 37% of the participants. Regarding the Foot and Ankle Outcome Score (FAOS) survey, the mean symptoms subscale score was 57.81 + 11.28, the mean pain subscale score was 72.87±20.84, the mean daily living subscale score was 72.73 ± 22.25, the mean sports and recreation subscale score was 76.83 ± 23.06, and the mean quality of life subscale score was 70.23 ± 25.17. Multivariate logistic regression was done and the following factors predicted a higher rate of plantar fasciitis: being 40 to 55 years old (p < 0.001, odds ratio = 2.15), being 56 to 65 years old (p = 0.037, odds ratio = 3.58), being obese (p = 0.031, odds ratio = 2.16), having weakness of the gastrocnemius, soleus, and the intrinsic foot muscles (p = 0.003, odds ratio = 7.39), jobs requiring a great amount of time standing or walking (p < 0.001, odds ratio = 3.17), and jobs requiring a moderate amount of time standing or walking (p = 0.012, odds ratio = 1.83). Being male predicted a lower rate of plantar fasciitis (p < 0.001, odds ratio = 0.52). Conclusion Plantar fasciitis is a prevalent and disabling condition with considerable effects on quality of life. Jobs that require long hours of walking or standing were associated with an increased risk of developing plantar fasciitis. Middle age, prolonged exercise, and gastrocnemius muscle tightness were also associated with plantar fasciitis. Efforts should be directed towards health education of the population regarding the risk factors and management of plantar fasciitis.

The association and reliability of the frontal plane projection angle during the lateral step down test on knee function in patients with patellofemoral pain. Knee 2022; 36:87-96. [PMID: 35561562 DOI: 10.1016/j.knee.2022.04.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 04/03/2022] [Accepted: 04/18/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND The lateral step-down test is used by physical therapists (PT) to identify movement faults in patients with patellofemoral pain (PFP). The FPPA is a measure of knee valgus and PTs have access to open source video analysis software and high quality smart phones and video cameras to implement 2D video analysis into practice. The purpose of our study was to determine the reliability of PTs measuring the frontal plane projection angle (FPPA) during the lateral step-down test, and to determine if the FPPA was associated with pain, self-reported knee function and fear of movement. METHODS Twenty-two subjects (mean age[SD] = 27.8 [6.6] years, females n = 14, males n = 8) with PFP were analyzed by six PTs using 2D video analysis software. The FPPA was measured during the lateral step down test. Numeric Pain Rating Scale (NPRS), Anterior Knee Pain Scale (AKPS) and the Tampa Scale of Kinesiophobia (TSK) were collected. Intraclass correlation (ICC) was used to assess for PT measurement reliability. Correlations between outcomes were calculated using Spearman correlation coefficient and standard error of measurement (SEM) and minimal detectable change (MDC) were reported. RESULTS Reliability amongst PTs measuring the FPPA was good (ICC [95 %CI] = 0.85 [0.72-0.93]; SEM = 3.33°, MDC = 9.20°). There were no significant correlations (p > 0.05) between FPPA and NPRS(ρ = -0.046), AKPS(ρ = 0.066), or TSK(ρ = -0.204). CONCLUSIONS Although reliability measuring FPPA was good, the large SEM and MDC associated with this measurement may limit its clinical utility in those with PFP.

Abstract
Background Strong evidence supports the proximal combined with quadriceps strengthening for patellofemoral pain (PFP) rehabilitation. However, most reported rehabilitation programs do not follow specific exercise prescription recommendations or do not provide adequate details for replication in clinical practice. Furthermore, people with PFP have power deficits in hip and knee muscles and it remains unknown whether the addition of power exercises would result in superior or more consistent outcomes. Therefore, this study is designed to verify whether the benefits of a rehabilitation program addressing proximal and knee muscles comprising power and strength exercises are greater than those of a program consisting of strength exercises only. Method This study will be a randomized controlled trial that will be conducted at university facilities. A minimum of 74 people with PFP between the ages of 18 and 45 years will be included. The experimental group will engage in a 12-week resistance training program focusing on proximal and knee muscles using power and strength exercises. The control group will engage in a 12-week resistance training program focusing on proximal and knee muscles using strength exercises only. Primary outcomes will be pain intensity and physical function; and secondary outcomes will be kinesiophobia, self-reported improvement, quality of life, peak hip and knee torque, and hip and knee rate of force development. The primary outcomes will be evaluated at baseline, and after 6 weeks, 12 weeks, 3 months, 6 months, and 1 year. The secondary outcomes will be evaluated at baseline and immediately after the interventions. Therapists and participants will not be blinded to group allocation. Discussion This randomized clinical trial will investigate if adding power exercises to a progressive resistance training may lead to more consistent outcomes for PFP rehabilitation. The study will provide additional knowledge to support rehabilitation programs for people with PFP. Trial registration ClinicalTrials.gov NCT 03985254. Registered on 26 August 2019.

Immediate Improvements in Patellofemoral Pain Are Associated With Sagittal Plane Movement Training to Improve Use of Gluteus Maximus Muscle During Single Limb Landing. Phys Ther 2021; 101:6309591. [PMID: 34174077 DOI: 10.1093/ptj/pzab165] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 03/16/2021] [Accepted: 05/15/2021] [Indexed: 11/13/2022]
Abstract
OBJECTIVE The authors sought to examine the immediate effects of movement training aimed at improving use of gluteus maximus (GMAX) in the sagittal plane on hip internal rotation and self-reported patellofemoral pain (PFP) during single-limb landing. METHODS Seventeen females with PFP participated. Lower extremity kinematics and kinetics, GMAX activation, and self-reported PFP were obtained before and after a single-session movement training program aimed at increasing the use of GMAX. Dependent variables of interest included self-reported PFP, average GMAX activation, average hip extensor moment, and peak hip internal rotation. Post-training changes were evaluated using paired t tests and Wilcoxon signed rank tests. RESULTS Following movement training, self-reported PFP decreased significantly (mean [standard deviation]) (3.9 [1.1] vs 0.8 [1.3] on a 0-10 scale). Additionally, significant increases were observed for the average hip extensor moment (0.6 [0.3] vs 1.8 [0.4] Nm/kg) and average GMAX activation (41.0% [18.3] vs 51.6% [25.7] maximum voluntary isometric contraction), whereas peak hip internal rotation decreased significantly (8.5 degrees [5.8] vs 6.0 degrees [5.3]). CONCLUSION Movement training aimed at improving the use of GMAX in the sagittal plane resulted in clinically relevant changes in self-reported pain, GMAX activation, and hip kinetics and kinematics. Improving the use of GMAX during movement merits consideration when designing rehabilitation programs for females with PFP. IMPACT The current study highlights the clinical utility of movement training for persons with PFP and provides a biomechanical rationale for its use as a potential intervention in this population.

Motor Control Exercises Compared to Strengthening Exercises for Upper- and Lower-Extremity Musculoskeletal Disorders: A Systematic Review With Meta-Analyses of Randomized Controlled Trials. Phys Ther 2021; 101:6145046.

Abstract
OBJECTIVE The purpose of this review was to compare the efficacy of motor control exercises (MCEs) to strengthening exercises for adults with upper- or lower-extremity musculoskeletal disorders (MSKDs). METHODS Electronic searches were conducted up to April 2020 in Medline, Embase, Cochrane CENTRAL, and CINAHL. Randomized controlled trials were identified on the efficacy of MCEs compared to strengthening exercises for adults with upper- or lower-extremity MSKDs. Data were extracted with a standardized form that documented the study characteristics and results. For pain and disability outcomes, pooled mean differences (MDs) and standardized mean differences (SMDs) were calculated using random-effects inverse variance models. RESULTS Twenty-one randomized controlled trials (n = 1244 participants) were included. Based on moderate-quality evidence, MCEs lead to greater pain (MD = -0.41 out of 10 points; 95% CI = -0.72 to -0.10; n = 626) and disability reductions (SMD = -0.28; 95% CI = -0.43 to -0.13; n = 713) when compared to strengthening exercises in the short term; these differences are not clinically important. When excluding trials on osteoarthritis (OA) participants and evaluating only the trials involving participants with rotator cuff-related shoulder pain, shoulder instability, hip-related groin pain, or patellofemoral pain syndrome, there is moderate quality evidence that MCEs lead to greater pain (MD = -0.74 out of 10 points; 95% CI = -1.22 to -0.26; n = 293) and disability reductions (SMD = -0.40; 95% CI = -0.61 to -0.19; n = 354) than strengthening exercises in the short term; these differences might be clinically important. CONCLUSIONS MCEs lead to statistically greater pain and disability reductions when compared to strengthening exercises among adults with MSKDs in the short term, but these effects might be clinically important only in conditions that do not involve OA. Inclusion of new trials might modify these conclusions. IMPACT These results suggest that MCEs could be prioritized over strengthening exercises for adults with the included non-OA MSKDs; however, results are unclear for OA disorders.

An Investigation of Knee Injury Profiles among Iranian Elite Karatekas: Observations from a Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18136888. [PMID: 34198965 PMCID: PMC8296942 DOI: 10.3390/ijerph18136888] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/17/2021] [Revised: 05/24/2021] [Accepted: 06/23/2021] [Indexed: 01/07/2023]
Abstract
Karate training, despite the many positive health benefits, carries a risk of injury for participants. The current cross-sectional study aimed to investigate knee injury profiles among Iranian elite karatekas. Participants who attended the national team qualifiers, which included 390 male Kumite karatekas (age 24 ± 3 years old and weight 63 ± 12 kg), participated in this study. Information on knee injuries (injury history, type of injury mechanisms, and effects of knee symptoms on the ability to perform daily activities and recreational activities) were obtained using the Knee Outcome Survey (KOS). Using Pearson's correlation coefficient, the study examined the relationships between different variables, including KOS subscales and levels of self-reported knee joint function. Our findings indicated that 287 karatekas (73.6%) experienced knee injuries. The anterior cruciate ligament (ACL) rupture (6.9%), articular cartilage (5.4%), and meniscus damage (3.8%) were the main typology of injury. In addition, there were no differences in knee injuries between the non-dominant and dominant legs. Most injuries occurred during the preparatory period (n = 162, 50%), especially during training periods. The KOS subscales scores (Mean ± Sd) for activities of daily living (ADL) and sports activity (SAS) were, respectively, 89 ± 11 and 91 ± 9. The self-reported scores for both the ADL and SAS subscales were, respectively, 89 ± 11 and 90 ± 10. Pearson coefficients of ADL and SAS subscales with their self-reported score were r = 0.761 (p < 0.0001) and r = 0.782 and (p < 0.0001), respectively. The profile of knee injuries in the current investigation is similar to previous surveys that reported lower extremity injury patterns. The findings of this study could be adopted to inform practice aimed at planning interventions for the reduction and prevention of knee injuries among karatekas.

Arch Phys Med Rehabil 2021; 102:1267-1273. [PMID: 33838141 DOI: 10.1016/j.apmr.2021.03.016] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 03/08/2021] [Accepted: 03/08/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To determine whether the addition of a brief psychologically informed video to traditional physical therapy influenced function (primary aim), pain, and psychological beliefs (secondary aims) among adolescents with patellofemoral pain (PFP). DESIGN Double-blind randomized controlled trial. SETTING Outpatient physical therapy clinics of a single pediatric hospital. PARTICIPANTS Sixty-six adolescents with PFP (14.8±1.7 years old, 65% female). INTERVENTION Adolescents were randomly assigned to view a brief psychologically informed video (n=34) or control video (n=32). The psychologically informed video targeted pain-related fear and pain catastrophizing, and the control video related basic anatomy and factors involved in PFP. MAIN OUTCOME MEASURES The primary outcome was change in function (Anterior Knee Pain Scale). Secondary outcomes were change in psychological beliefs (fear-avoidance beliefs, kinesiophobia, pain catastrophizing) and pain. Outcomes were assessed at baseline, immediately post intervention, at 2 weeks, at 6 weeks, and at 3 months. RESULTS Using a 2-way mixed analysis of variance, change in function in the intervention group was greater than the control group, with a moderate treatment effect noted (P=.001, partial η2=0.1). Post hoc testing revealed that there was a significant interaction between the intervention and time from baseline to 2 weeks, but no interaction was noted between 2 weeks and 3 months. The psychologically informed video significantly reduced maladaptive psychological beliefs (P=.01, η2=0.32). No significant between-group differences in pain were noted. CONCLUSIONS Incorporating a brief one-time psychologically informed video into standard physical therapy care significantly reduced pain-related fear, reduced pain catastrophizing, and improved function among adolescents with PFP. The immediate effect noted on function did not continue throughout the course of care.

Abstract
Rehabilitation has been shown to improve functional outcomes following total knee replacement (TKR). However, its delivery and associated costs are highly variable. The authors have developed and previously validated the accuracy of a remote (wearable) rehabilitation monitoring platform (interACTION). The present study’s objective was to assess the feasibility of utilizing interACTION for the remote management of rehabilitation after TKR and to determine a preliminary estimate of the effects of the interACTION system on the value of rehabilitation. Specifically, we tested post-operative outpatient rehabilitation supplemented with interACTION (n = 13) by comparing it to a standard post-operative outpatient rehabilitation program (n = 12) using a randomized design. Attrition rates were relatively low and not significantly different between groups, indicating that participants found both interventions acceptable. A small (not statistically significant) decrease in the number of physical therapy visits was observed in the interACTION Group, therefore no significant difference in total cost could be observed. All patients and physical therapists in the interACTION Group indicated that they would use the system again in the future. Therefore, the next steps are to address the concerns identified in this pilot study and to expand the platform to include behavioral change strategies prior to conducting a full-scale randomized controlled trial.

Abstract
OBJECTIVES A prospective observational cohort study was conducted to 1) determine the prevalence of Mechanical Diagnosis and Therapy (MDT) syndromes for patients with knee impairments, and 2) report the interaction between MDT classification and clinical outcomes, including pain intensity and disability, at discharge. METHODS Clinical outcome measures were completed at intake and discharge on 186 patients. A two-way mixed model analysis of variance with subsequent pairwise comparisons was done to examine differences between the following MDT classifications: Knee Derangement, Knee Dysfunction, and Other. RESULTS The primary findings were that: 1) 61.3% (54.3, 68.3), 9.7% (5.4, 13.9), and 29.0% (22.5, 35.5) of patients' conditions were classified as Knee Derangement, Knee Dysfunction, and Other, respectively; 2) all groups managed via MDT methods made clinically significant improvements in disability and pain intensity at discharge with the exception of the Other classification for pain intensity (NPRS difference score = 1.8); 3) a clinically significant difference was observed between the Knee Derangement and Other for pain and between the Knee Derangement and Other and the Knee Dysfunction and Other classifications for disability; and 4) the Knee Derangement classification was discharged, on average, 15.8 days earlier than the Knee Dysfunction classification. DISCUSSION This was the first prospective study of the application of MDT in patients with knee impairments. Results should be interpreted with caution as follow-up data were only completed on 58% of patients that started data collection. Assuming that none of the dropouts were Derangement, the overall prevalence of Derangement would be 32.2% and 79.7% if all dropouts were classified as Derangement. This study adds insight into understanding the unique clinical trajectories of these MDT classifications for the knee and offers recommendations for future work in this growing field of research.

Abstract
BACKGROUND Patellofemoral pain syndrome (PFPS), characterized by retropatellar and peripatellar pain, is a common disorder affecting young women. Treatment has included exercise-based therapy and taping techniques for rapid reduction of symptoms and pain. Although Kinesio Taping® (KT) has been studied as adjunctive therapy, evidence on its effectiveness is limited and conflicting. OBJECTIVE To determine the feasibility of performing a double-blind randomized controlled trial (RCT) using KT® for PFPS treatment and to determine an ideal sample size. DESIGN Double-blind, randomized, controlled pilot study. METHOD Forty-three women (aged 18-45 years) with at least a 3-month history of PFPS were randomized based on the mechanical correction techniques: using KT® for patellar medialization (KT-PM), using KT® for lateral rotation of the femur and tibia (KT-LRFT), and the control group (CG). All groups underwent the same muscle strengthening and motor control procedures for 12 weeks. Knee pain and function were evaluated at baseline, at 6 weeks, at treatment completion (12 weeks), and during the 12-week follow-up using the numerical pain rating scale (NPRS) at rest and during effort, Anterior Knee Pain Scale (AKPS), and single jump hop test. RESULTS There were clinically significant differences between the KT-LRFT and the CG in terms of AKPS and NPRS scores during effort at the 6-week and 12-week follow-ups. All groups (within group) showed a significant improvement in pain and function. CONCLUSIONS A complete RCT using KT® for the treatment of PFPS is feasible with some changes regarding outcome measures and treatment protocols.

Abstract
BACKGROUND Aberrant frontal-plane hip and pelvis kinematics have been frequently observed in runners with patellofemoral pain (PFP). Gait retaining interventions have been shown to improve running kinematics and may therefore be beneficial in runners with PFP. PURPOSE To investigate whether a 10% increase in the running step rate influences frontal-plane kinematics of the hip and pelvis as well as clinical outcomes in runners with PFP. STUDY DESIGN Case series; Level of evidence, 4. METHODS Runners with PFP underwent a 3-dimensional gait analysis to confirm the presence of aberrant frontal-plane hip and/or pelvis kinematics at baseline. A total of 12 participants with frontal-plane hip and/or pelvis kinematics 1 standard deviation above a reference database were invited to undergo the gait retraining intervention. Running kinematics along with clinical outcomes of pain and functional outcomes were recorded at baseline, 4 weeks after retraining, and 3 months. Gait retraining consisted of a single session where step rate was increased by 10% using an audible metronome. Participants were asked to continue their normal running while self-monitoring their step rate using a global positioning system smartwatch and audible metronome. RESULTS After gait retraining, significant improvements in running kinematics and clinical outcomes were observed at 4-week and 3-month follow-up. Repeated-measures analysis of variance with post hoc Bonferroni correction (P < .016) showed significant reductions in peak contralateral pelvic drop (mean difference [MD], 3.12° [95% CI, 1.88°-4.37°]), hip adduction (MD, 3.99° [95% CI, 2.01°-5.96°]), and knee flexion (MD, 4.09° [95% CI, 0.04°-8.15°]) as well as significant increases in self-reported weekly running volume (MD, 13.78 km [95% CI, 4.62-22.93 km]) and longest run pain-free (MD, 6.84 km [95% CI, 3.05-10.62 km]). Friedman test with a post hoc Wilcoxon signed-rank test showed significant improvements on a numerical rating scale for worst pain in the past week and the Lower Extremity Functional Scale. CONCLUSION A single session of gait retraining using a 10% increase in step rate resulted in significant improvements in running kinematics, pain, and function in runners with PFP. These improvements were maintained at 3-month follow-up. It is important to assess for aberrant running kinematics at baseline to ensure that gait interventions are targeted appropriately.

Abstract
Background Patellofemoral pain (PFP) often affects young women, and the etiology is multifactorial and poorly understood. Conservative intervention has been focused on risk factors or aggravating factors and is composed of hip- and knee-strengthening exercises, as this population often has muscle weakness and poor motor control during daily and sports activities. The objective of this study was to evaluate the additional effects of neuromuscular training in a conservative treatment of trunk-, hip-, and knee-muscle strengthening on pain, function, and kinematics of the trunk, pelvis, and lower limb in women with PFP. Methods This is a randomised clinical trial, controlled, blinded. Ninety women who are active and engage in physical activity up to twice a week will be recruited. All participants will undergo an individual physiotherapy assessment and then will be allocated randomly into two groups. Thereafter, both groups will undergo a 12-week intervention protocol: group 1 will perform strengthening exercises for the trunk, hip, and knee muscles, while group 2 will receive the same treatment, with the inclusion of neuromuscular training exercises on the fourth week. At the end of the intervention, the volunteers will be evaluated. The primary outcomes will be pain intensity (using a Visual Analog Scale: over the last month, squat 90°, and step of 26 cm during 1 min), functional capacity (Anterior Knee Pain Scale and Activities of Daily Living Scale), and 2D kinematics of the trunk, pelvis, and lower limb during the single-leg squat. The secondary outcomes correspond to the isometric muscular strength of the lower limb and the level of satisfaction from the intervention. Discussion The present study was initiated on 28 January 2018 and is currently in progress, scheduled for completion in July 2019. The results of this study should contribute to the physiotherapeutic treatment of women with PFP by aggregating information on the benefits of adding neuromuscular training to strengthening of the trunk and lower-limb muscles.

Abstract
Patellofemoral pain (PFP) is a common musculoskeletal-related condition that is characterized by insidious onset of poorly defined pain, localized to the anterior retropatellar and/or peripatellar region of the knee. The onset of symptoms can be slow or acutely develop with a worsening of pain accompanying lower-limb loading activities (eg, squatting, prolonged sitting, ascending/descending stairs, jumping, or running). Symptoms can restrict participation in physical activity, sports, and work, as well as recur and persist for years. This clinical practice guideline will allow physical therapists and other rehabilitation specialists to stay up to date with evolving PFP knowledge and practices, and help them to make evidence-based treatment decisions.

Abstract
BACKGROUND AND PURPOSE Documenting functional outcomes after reverse shoulder arthroplasty (RSA) is critical to advancing patient care. The interplay been self-reported and objectively measured outcome measures has not been widely described. The utilization of wearable devices to document upper extremity limb activity is a new approach for objectively measuring outcomes. Therefore, the purpose of this study was to evaluate changes in pain, and self-reported function and objectively measured limb activity after RSA. We also assessed the influence of pain on self-reported function and objectively measured limb activity to determine the impact of pain on outcomes after RSA. MATERIALS This study implemented a prospective, repeated-measures design. Fourteen patients undergoing RSA underwent testing before surgery, and 2 and 12 months after surgery. Patient-reported instruments included pain, Disabilities of Arm, Shoulder and hands (DASH), and physical component summary (PCS) of the 36-Item Short Form Health Survey. Objective limb activity (mean activity value, m/s/min epoch; inactive time, %; low activity, %; and high activity, %) was captured with triaxial accelerometers worn on the upper and lower arm. A repeated-measures ANOVA tested for differences across time. The Spearman rank-order correlation was calculated to evaluate the influence of pain on DASH, PCS scores, and mean limb activity. RESULTS Patient-reported measures improved after surgery (pain, P < .01; DASH, P < .01; PCS, P = .01). No change in limb activity was found at 1 year compared with preoperative values for mean (forearm, P = 1.00; arm, P = .36), inactivity (forearm, P = .33; arm, P = .22), low (forearm, P = .77; arm, P = .11) or high (forearm, P = 1.00; arm, P = .20) activity. There was a relationship between pain and DASH scores 1 year after surgery (P = .04) but not before surgery (P = .16), or 2 months after surgery (P = .30). There was no relationship between pain and PCS scores at any time point (preoperative, P = .97; 2 months, P = .21; 1 year, P = .08) nor pain and limb activity (forearm: preoperative, P = .36; 2 months, P = .67; 1 year, P = .16; arm: preoperative, P = .97; 2 months, P = .59; 1 year, P = .51). CONCLUSIONS RSA reduced pain and enhanced patient-perceived function. Objectively measured upper extremity limb activity is not different 1 year after surgery compared with preoperative levels.

Abstract
Background The Knee Outcome Survey Activities of Daily Living Scale (KOS-ADLS) is a self-reported questionnaire used for the evaluation of the overall health of patients with knee dysfunctions. The purpose of this study was to perform a cross-cultural adaptation of the Polish version of KOS-ADLS and to evaluate its psychometric properties in patients at the end-stage of knee osteoarthritis who were qualified for a total knee replacement (TKR). Material/Methods Seventy patients consecutively qualified for surgical TKR procedure participated in this study. To adapt the KOS-ADLS, the following scales and reference tests were used: Knee injury and Osteoarthritis Outcome Score (KOOS), Visual Analogue Scale (VAS), Time Up and Go test (TUG), and Five Times Sit to Stand test (5×STS). The studies were conducted 3 times: 2 weeks before surgery (first study), 6 to 13 days later (retest), and 6 months after surgery. Results The Polish version of KOS-ADLS showed excellent reliability (ICC=0.89 SEM=2.68, MDC=7.43) and high responsiveness (ES=4.76, SRM=3.18). The internal consistency was poor in the first assessment (Cronbach’s alpha=0.68), but acceptable in the post-surgery evaluation (Cronbach’s alpha=0.86). There were fair and moderate correlations found between KOS-ADLS and VAS scales in the first examination, TUG, and 5×STS. Stronger correlations were observed between the results obtained in KOS-ADLS and KOOS. Conclusions The Polish version of the KOS-ADLS demonstrated good reliability, validity, and responsiveness for use in patients who have undergone TKR surgery.

Abstract
Objective: To compare a sequential treatment algorithm considering psychosocial and physical impairments, with a conventional rehabilitation approach considering only physical impairments in adolescents with patellofemoral pain. Design: A randomized, single-blind, controlled study. Participants: Fifty-five adolescents (36 females; mean age 14.3 ± 1.8 years). Interventions: The sequential cognitive and physical approach (SCOPA) group ( n = 28) was treated based on sequential testing and treatment of activity-related fear, flexibility, kinematics, and strength. The comparator group ( n = 27) was treated with a non-sequential physical impairment–based approach. Both groups received treatment two times a week for up to six weeks. Measurements: Function (Anterior Knee Pain Scale), pain (Numeric Pain Rating Scale), and Global Rating of Change were assessed at baseline, three weeks, and six weeks, with a six-month follow-up. Results: Both groups had similar function (73.7 ± 9.6) and pain (6.0 ± 2.3) at baseline. A third of individuals with patellofemoral pain demonstrated elevated activity-related fear at baseline. Patients randomized to the SCOPA group had clinically significant greater improvements at six weeks in function (SCOPA, 95.0 ± 7.4 and comparator, 84.8 ± 10.4; mean difference: 10.2, 95% CI: 5.3, 15.1) and pain (SCOPA, 0.9 ± 1.9 and comparator, 2.7 ± 2.1; mean difference: 1.7, 95% CI: 0.5, 2.9). No differences were noted in Global Rating of Change. No between-group differences were noted in any outcome at six-month follow-up. Conclusion: The sequential cognitive and physical approach resulted in greater improvements in short-term function and pain. By six months, both groups demonstrated similar clinically significant improvements in all outcomes.

Abstract
BACKGROUND AND PURPOSE Chronic instability of the proximal tibiofibular joint (PTFJ) is an uncommon condition that accounts for <1% of knee injuries. The mechanism of injury is a high-velocity twisting motion on a flexed knee. Surgical management is controversial due to complications; however, surgeons are now utilizing ligament reconstruction to restore stability. There is a paucity of information in the literature regarding postoperative care and rehabilitation after PTFJ reconstruction. The purpose of this case report is to describe the post-surgical rehabilitation for an adolescent athlete following PTFJ ligament reconstruction using a modified anterior cruciate ligament reconstruction (ACL) post-operative rehabilitation protocol. CASE DESCRIPTION A 15-year-old female soccer player reported left ankle and knee pain for one year after a contact injury and landing on a hyperflexed knee during a soccer game. The surgeon diagnosed the subject with chronic PTFJ instability and performed reconstruction using an allograft ligament and calcium phosphate bone graft. The subject presented to physical therapy three weeks post-operatively with complete resolution of ankle pain and mild knee pain. The subject's goal was to return to golf as she reported apprehension with a potential return to soccer. After consulting with the surgeon and because the subject was only allowed to advance weight bearing status by 20 pounds each week (to protect the graft site), the treating therapists progressed the subject using a modified ACL protocol as there is no documented post-operative rehabilitation protocol to treat patients after a PTFJ reconstruction. OUTCOMES Outcome measures for this subject included the patient specific functional scale (PSFS), verbal numeric pain rating scale and ability to participate in golf. The initial PSFS score was 4/30 (activities included walking, jogging and golf) and the subject's reported pain level was 3/10. Three months after surgery the subject demonstrated significant improvement to 30/30 on the PSFS, 0/10 pain, and had progressed to participation in both golf and jogging. DISCUSSION The modified ACL protocol was effective in safely rehabilitating this adolescent athlete following a PTFJ reconstruction. This subject demonstrated some yellow flags which may have slowed her rehabilitation progression. Use of a modified ACL reconstruction protocol served as a guideline for the rehabilitation of this rare condition. Additional research is necessary to establish evidence-based guidelines for treatment of PTFJ reconstruction. LEVEL OF EVIDENCE Level 4.

Abstract
BACKGROUND Patellofemoral pain is common in physically active adults. Females with patellofemoral pain have been shown to have posterolateral hip muscle weakness, but there is a paucity of research examining hip muscle strength in males with patellofemoral pain. HYPOTHESIS/PURPOSE The purpose of this study was to examine posterolateral hip muscle strength in males with patellofemoral pain compared to asymptomatic males. It was hypothesized that males with patellofemoral pain would have decreased strength of the hip extensor, hip external rotator, and hip abductor muscles compared to healthy, asymptomatic males. STUDY DESIGN Descriptive, cross-sectional. METHODS Thirty-six adult males with patellofemoral pain and 36 pain-free males participated in the study. The patellofemoral pain group were required to have retropatellar pain reproduced by activities that loaded the patellofemoral joint (squatting, descending stairs, etc.). Peak isometric torque of the hip extensors, hip external rotators, and hip abductors was measured with an instrumented dynamometer. Torque was normalized by body mass and height. Between-group differences were analyzed with parametric or non-parametric tests, as appropriate. The level of significance was adjusted for multiple comparisons. RESULTS Hip extensor torque was significantly reduced in the patellofemoral pain group compared to the control group (p = .0165). No differences were found between groups for the hip external rotators or hip abductors (p > .0167). CONCLUSION Males with patellofemoral pain appear to have weakness of the hip extensors, but unlike females with patellofemoral pain, they do not appear to have weakness of the hip abductors or hip external rotators. The findings of this study suggest that muscle strength factors associated with patellofemoral pain in males may be different from muscle strength factors in females. Clinicians examining and designing plans of care for male patients with patellofemoral pain should consider that the hip abductors and hip external rotators may not be weak in men with this condition.

Abstract
BACKGROUND The purpose of this study was to determine the epidemiology and history of knee injury and its impact on activity limitation among football premier league professional referees in Iran. METHODS This was a descriptive study. 59 Football Premier League professional referees participated in the study. The knee injury related information such as injury history and mechanism was recorded. Injury related symptoms and their impacts on the activity limitation, ability to perform activities of daily living as well participation in sports and recreational activities was obtained through the Knee Outcome Survey (KOS). RESULTS The results indicated that 31 out of 59 participants reported the history of knee injury. In addition, 18.6%, 22.4% and 81% of the referees reported that they had been injured during the last 6 months of the last year, and at some point in their refereeing careers, respectively. Results further indicated that 48.8% of the injuries occurred in the non-dominant leg and they occurred more frequently during training sessions (52%). Furthermore, the value of KOS was 85 ± 13 for Activities of Daily Living subscale and 90 ± 9 for Sports and Recreational Activities subscale of the KOS. CONCLUSIONS Knee injury was quite common among the Football Premier League professional referees. It was also indicated that the injuries occurred mainly due to insufficient physical fitness. Therefore, it is suggested that football referees undergo the proper warm-up program to avoid knee injury.

Abstract
BACKGROUND The Centers for Medicare and Medicaid Services (CMS) require physical therapists document patients' functional limitations. The process is not standardized.
A systematic approach to determine a patient's functional limitations and responsiveness to change is needed. OBJECTIVE The purpose of this study is to compare patient-reported outcomes (PROs) responsiveness to change using 7-level severity/complexity modifier scale proposed by Medicare to a derived scale implemented by Intermountain Healthcare's Rehabilitation Outcomes Management System (ROMS). DESIGN This was a retrospective, observational cohort design. METHODS 165,183 PROs prior to July 1, 2013, were compared to 46,334 records from July 1, 2013, to December 31, 2015. Histograms and ribbon plots illustrate distribution and change of patients' scores. ROMS raw score ranges were calculated and compared to CMS' severity/complexity levels based on score percentage. Distribution of the population was compared based on the 2 methods. Sensitivity and specificity were compared for responsiveness to change based on minimal clinically important difference (MCID). RESULTS Histograms demonstrated few patient scores placed in CMS scale levels at the extremes, whereas the majority of scores placed in 2 middle levels (CJ, CK). ROMS distributed scores more evenly across levels. Ribbon plots illustrated advantage of ROMS' using narrower score ranges. Greater chance for patients to change levels was observed with ROMS when an MCID was achieved. ROMS narrower scale levels resulted in greater sensitivity and good specificity. LIMITATIONS Geographic representation for the United States was limited. Without patients' global rating of change, a reference standard to gauge validation of improvement could not be provided. CONCLUSIONS ROMS provides a standard approach to identify accurately functional limitation modifier levels and to detect improvement more accurately than a straight across transposition using the CMS scale.

Abstract
BACKGROUND AND PURPOSE Multimodal interventions possess the strongest evidence in the long-term management of patellofemoral pain, but despite receiving evidence-based treatments that are initially effective many patients report recurrent or persistent symptoms for years after the initial diagnosis. Untreated psychological factors could be a possible explanation for persistent symptoms and poor treatment outcome. The purpose of this case report was to describe and evaluate the effects of a multimodal rehabilitation program that included pain education, a graded program of lower limb strengthening, and running retraining on pain, kinesiophobia, and function in a runner with patellofemoral pain. CASE DESCRIPTION The subject was a 37-year-old female runner reporting a 12-month history of anterior knee pain with previous failed physiotherapeutic treatment. She discontinued running when symptoms gradually worsened, approximately six months after initial onset. She was advised to avoid painful activities. Clinical examination revealed pain during the performance of a weight-bearing functional task, fear of movement, and functional limitations. Treatment focused on pain education, self-management strategies, and progressive loading of the involved tissues through a graduated program of exercises and running retraining. OUTCOMES Clinically meaningful improvements were seen in pain, kinesiophobia, and function following a 21-week multimodal rehabilitation program. DISCUSSION This case report illustrates several important aspects of clinical reasoning contributing to successful outcomes for a runner with patellofemoral pain. The multimodal rehabilitation program utilized was based upon the neurophysiology of pain (pain education) rather than the tissue pathology model. The findings from this case report may be used to benefit clinicians with similar subject presentations and drive future research into the use of these interventions based upon neurophysiology models of pain in the treatment of patellofemoral pain.

Abstract
BACKGROUND With increasing number of patients with early osteoarthritis of knee opting for total knee arthroplasty (TKA), there has been increase in patients dissatisfied with surgical outcomes. It is being presumed that offering unicondylar knee arthroplasty (UKA) to them would improve outcomes. METHODS Primary objective of our study was to look for any difference in patient-reported outcome and function at 2-year follow-up in patients undergoing UKA as compared to TKA. Our study was a randomized study with parallel assignment conducted at a high-volume specialized arthroplasty center. Eighty patients with bilateral isolated medial compartment knee arthritis were randomized into simultaneous 2-team bilateral TKA (n = 40) and UKA (n = 40) group. We finally analyzed 36 patients in each group. Main outcome measure was improvement in Knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS) and High Activity Arthroplasty Score (HAAS) obtained at 2-year follow-up. RESULTS Improvement in KOS-ADLS and HAAS at 2 years was similar (P = .2143 and .2010) in both groups. Performance as assessed with Delaware index was also similar. Length of hospital stay was less in UKA group (6.6 days as against 5.4 days). Complications and readmission rates were more in TKA group (nil in UKA group; 08 in TKA group). CONCLUSION At 2-year follow-up, UKA provides similar improvement in patient-reported outcomes, function, and performance as compared to TKA when performed in patients with early arthritis. However, UKA patients have shorter hospital stay and fewer complications.

Abstract
OBJECTIVE The purpose of this prospective cohort study was to determine if a new patella fracture fixation construct resulted in improved outcomes compared with traditional tension band techniques. DESIGN Comparative cohort study. SETTING Academic level I trauma center. PATIENTS/PARTICIPANTS Patients with isolated, unilateral patellar fractures were enrolled prospectively. From 2012 to 2014, 33 patients underwent fixation with a novel plate construct that spans half of the patella circumference laterally and provides multiplanar fixation through a low-profile plate. A comparison cohort was drawn from 25 patients treated from 2008 to 2012, where treatment consisted of traditional tension band fixation techniques. INTERVENTION Surgical fixation of patella fractures was performed with either a tension band or novel plate construct. MAIN OUTCOME MEASUREMENTS Subjective postoperative clinical outcomes and objective functional and strength measurements were subsequently collected. RESULTS The 2 cohorts had similar baseline characteristics. Patients with the plate construct had clinically and statistically significantly superior Knee Outcome Survey Activities of Daily Living Scale (KOS-ADLS) scores throughout the study period (P < 0.001). Functional testing also demonstrated significant improvements in patients with plate constructs compared with tension band constructs at 12 months. Patients in the plate cohort had significantly increased thigh circumferences (P = 0.003) and decreased anterior knee pain (P < 0.0001) compared with the tension band cohort. CONCLUSIONS In this prospective cohort study, the use of a novel fixation construct with multiplanar and interfragmentary fixation and minimal disruption of patellar vascularity enables improved clinical outcomes and functional performance. LEVEL OF EVIDENCE Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Abstract
PURPOSE To perform a cross-cultural adaptation and translation of the original version of the Activities of Daily Living Scale of the Knee Outcome Survey into Simplified Chinese and validate of the Simplified Chinese version. METHODS The original version was translated and cross-culturally adapted into Simplified Chinese according to the guidelines and the recommendations of the American Academy of Orthopaedic Surgeons Outcome Committee. A total of 213 patients (96 male, 117 female) were selected to participate in our investigation. The inclusion criteria were as follows: 18 years of age and older, able to speak Chinese Mandarin and read Simplified Chinese, and referred to physical therapy for evaluation and treatment for a knee disorder. The exclusion criteria were as follows: patients who had disorders or impairments involving both knees, patients who had other conditions that could affect lower extremity function, patients with physical therapy related to the knee in the previous 1 month, and patients with psychological problems. Each participant was asked to complete the Knee Outcome Survey Activities of Daily Living Scale (KOS-ADLS), International Knee Documentation Committee Subjective Knee Form, Western Ontario and McMaster Universities Osteoarthritis Index, and Short Form 36 forms and to provide baseline demographic data. Each participant completed the KOS-ADLS twice on 2 nonconsecutive days for reliability evaluation. A portion of the participants (n = 161) finished the KOS-ADLS a third time 4 weeks after physical treatment to test responsiveness. RESULTS The original version of the KOS-ADLS was well adapted and translated into Simplified Chinese. Simplified Chinese of KOS-ADLS was shown to have good internal consistency (Cronbach's alpha = 0.855 to 0.929), great test-retest reliability (intraclass correlation coefficient = 0.935 to 0.961), high construct validity as we hypothesized (significant correlations with Short Form 36 subscales, Western Ontario and McMaster Universities Osteoarthritis Index, and International Knee Documentation Committee Subjective Knee Form), and high responsiveness (standard response means = 0.97 to 1.23, standard effect size = 0.81 to 0.91). CONCLUSIONS Simplified Chinese of KOS-ADLS was shown to have good reliability, validity, and responsiveness for use in patients with knee disorders in China. LEVEL OF EVIDENCE Level II, testing of previously developed diagnostic criteria in a series of consecutive patients with universally applied gold standard.

Abstract
BACKGROUND AND PURPOSE Patellofemoral pain syndrome (PFPS) is a common source of anterior knee pain. Controversy exists over the exact clinical findings which define PFPS, thus, diagnosis and management can be challenging for clinicians. There is paucity in the literature concerning joint mobilization as treatment for PFPS, particularly at the tibiofemoral joint, as standard management is currently focused on therapeutic exercise, orthotics, bracing and taping. Therefore, the purpose of this case report is to describe the effects of tibiofemoral joint mobilization in the successful treatment of an individual with chronic PFPS as it relates to pain, function and central processing of pain. STUDY DESIGN Case Report. CASE DESCRIPTION The subject was a 28-year-old female with a two year history of left anterior, inferior patellar knee pain consistent with chronic PFPS. She demonstrated diminished pressure pain threshold (PPT) and allodynia at the anterior knee, suggesting a component of central sensitization to her pain. She met several common diagnostic criteria for PFPS, however, only tibiofemoral anterior-posterior joint mobilization increased her pain. Subsequent treatment sessions (Visits 1-6) consisted of solely joint mobilization supplemented by instruction in a home exercise program (therapeutic exercise and balance training). As outcomes improved, treatment sessions (Visits 7-8) consisted of solely therapeutic exercise and balance training with focus on return to independent pain free functional activity. OUTCOMES Improvements consistent with the minimally clinically important difference were noted on the Kujala Anterior Knee Pain Scale, Numeric Pain Rating Scale, Global Rating of Change (GROC). Scores on the Fear Avoidance-Belief Questionnaire (6/24 to 2/24 PA, 31/42 to 5/42 W), PPT (119 to 386 kPa) and Step Down Test (11 to 40 steps) also demonstrated improvement. At a two month follow up, the subject reported continued improvement in functional activity, 0/10 pain and GROC = +5. DISCUSSION This case describes the successful use of tibiofemoral joint mobilization in a subject with chronic PFPS and supports the use of joint mobilization as management in PFPS, particularly in cases where a centrally mediated component of pain may be present.

Abstract
[Purpose] Patellofemoral pain syndrome is a frequent musculoskeletal disorder, which can
result from core muscles instability that can lead to pain and altered dynamic balance.
The objective of this study is to assess the effect of core muscle strengthening on pain
and dynamic balance in female patients with patellofemoral pain syndrome. [Subjects and
Methods] Twenty female patients with age ranging from 16 to 40 years with patellofemoral
pain syndrome were divided into study (N=10) and control (N=10) groups. Both groups were
given 4 weeks of conventional physical therapy program and an additional core muscle
strengthening for the study group. The tools used to assess the outcome were Visual
Analogue Scale and Star Excursion Balance Test. [Results] The results of the study show
that participants in the study group revealed a significantly greater improvement in the
intensity of pain and dynamic balance as compared to the control group. [Conclusion]
Adding a core muscle-strengthening program to the conventional physical therapy management
improves pain and dynamic balance in female patients with patellofemoral pain
syndrome.

Abstract
CONTEXT Greater knee-joint laxity may lead to a higher risk of knee injury, yet it is unknown whether results of self-reported outcome measures are associated with distinct knee-laxity profiles. OBJECTIVE To identify the extent to which multiplanar knee laxity is associated with patient-reported outcomes of knee function in healthy individuals during activities of daily living and sport. DESIGN Descriptive laboratory study. SETTING University research laboratory. PATIENTS OR OTHER PARTICIPANTS Forty healthy individuals (20 men, 20 women; age = 18-31 years). MAIN OUTCOME MEASURE(S) All participants were given the Knee Outcome Survey Activities of Daily Living Scale (KOS-ADL) and Sports Activities Scale (KOS-SAS) and subsequently measured for knee laxity in the sagittal, frontal, and transverse planes. Separate backward stepwise regression analyses were performed to determine the extent to which multiplanar knee-laxity values predicted KOS-ADL and KOS-SAS scores within each sex. RESULTS Women had higher magnitudes of anterior, posterior (POST(LAX)), varus (VAR(LAX)), valgus (VAL(LAX)), and internal-rotation laxity than men and trended toward greater external rotation (ER(LAX)) laxity. Greater POST(LAX), less VAL(LAX), and greater VAR(LAX) was associated with lower KOS-ADL scores (KOS-ADL = -4.8 [POST(LAX)], + 3.3 [VAL(LAX)] - 2.2 [VAR(LAX)] + 100.4, R2 = 0.74, P < .001) and greater POST(LAX) and less VAL(LAX) was associated with lower KOS-SAS scores (KOS-SAS = -8.2 [POST(LAX)], + 3.6 [VAL(LAX)] + 96.4, R2 = 0.67, P < .001) in women. In men, greater POST(LAX) and less ER(LAX) was associated with lower KOS-SAS scores (KOS-ADL = -4.7 [POST(LAX)], + 0.9 [ER(LAX)] + 96.4, R2 = 0.49, P < .001). CONCLUSIONS The combination of POST(LAX) with less relative VAL(LAX) (women) or less relative ER(LAX) (men) was a strong predictor of KOS scores, suggesting that a self-reported outcome measure may be beneficial as part of a preparticipation screening battery to identify those with perceived functional deficits associated with their knee laxity.

Abstract
OBJECTIVES Several patient-reported outcome (PRO) instruments have been validated in AS. This study aims to evaluate several measurement properties of such PROs in a broad axial SpA (axSpA) population, including both AS and non-radiographic axSpA (nr-axSpA) subpopulations. METHODS PROs assessed were total and nocturnal back pain, patient global assessment of disease activity, BASDAI, BASFI and the 36-item Short Form Health Survey. A literature review and both clinician and patient qualitative interviews provided information on instrument content validity. Reliability (test-retest and internal consistency), construct validity (PROs, clinical-outcome correlations and known-groups validity) and PRO responsiveness were assessed. Data from the RAPID-axSpA trial (NCT01087762) investigating certolizumab pegol efficacy in axSpA, including relevant subpopulations, were utilized. RESULTS Concepts identified for the broad axSpA population by both clinician and patient interviews were consistent with those identified through literature review of AS. All PROs demonstrated reliability in the RAPID-axSpA population (n = 325), with test-retest intraclass correlation coefficients and internal consistency Cronbach's α >0.8. Validity was supported by agreement between PROs and clinician-rated measures; except for the 36-item Short Form Health Survey Mental Components Summary, correlations between PROs and physician global assessment of disease activity ranged from 0.28 to 0.42 for week 0 and from 0.53 to 0.65 for week 24. PRO measures showed good sensitivity to change (effect size >0.8) at weeks 12 and 24 for responders. No variations in measurement properties were noted between the subpopulations. CONCLUSION This study indicates that both content validity and measurement properties of PRO instruments utilized in AS are preserved in the broad axSpA population.

Abstract
Background To create and validate a German version of the Tonsil and Adenoid Health Status Instrument (TAHSI) for evaluation of tonsillectomy outcome in adult patients with chronic or recurrent tonsillitis. Subjects and methods 46 healthy volunteers were assessed twice in a 6 week interval with the TAHSI questionnaire. Their results were compared with 45 patients suffering from chronic tonsillitis before tonsillectomy and 6 months following surgery. For internal consistency, Cronbach’s alpha was calculated; to identify normal score values, the optimum cutoff between healthy and diseased individuals was identified with receiver operating characteristic analysis; and responsiveness was assessed using Guyatt’s Responsiveness Index (GRI). Results Cronbach’s alpha for all questions was 0.92. Test- retest intraclass correlation coefficient was 0.89 (95% confidence interval 0.80-0.94 p < 0.001). Mean score for the healthy individuals was 7.0 (95% confidence interval 4.2-9.7). The optimum cut off score between healthy and diseased was 20 with a sensitivity of 80% and a specificity of 90% to differentiate controls from tonsillectomy patients. Conclusion The TAHSI performed well in this validation tests and is considered a favorable instrument to evaluate the effectiveness of tonsillectomy in adults with chronic or recurrent tonsillitis.

Abstract
This systematic review investigated the measurement properties of disease-specific patient-reported outcome measures used in Patellofemoral Pain Syndrome. Two independent reviewers conducted a systematic search of key databases (MEDLINE, EMBASE, AMED, CINHAL+ and the Cochrane Library from inception to August 2013) to identify relevant studies. A third reviewer mediated in the event of disagreement. Methodological quality was evaluated using the validated COSMIN (Consensus-based Standards for the Selection of Health Measurement Instruments) tool. Data synthesis across studies determined the level of evidence for each patient-reported outcome measure. The search strategy returned 2177 citations. Following the eligibility review phase, seven studies, evaluating twelve different patient-reported outcome measures, met inclusion criteria. A 'moderate' level of evidence supported the structural validity of several measures: the Flandry Questionnaire, Anterior Knee Pain Scale, Functional Index Questionnaire, Eng and Pierrynowski Questionnaire and Visual Analogue Scales for 'usual' and 'worst' pain. In addition, there was a 'Limited' level of evidence supporting the test-retest reliability and validity (cross-cultural, hypothesis testing) of the Persian version of the Anterior Knee Pain Scale. Other measurement properties were evaluated with poor methodological quality, and many properties were not evaluated in any of the included papers. Current disease-specific outcome measures for Patellofemoral Pain Syndrome require further investigation. Future studies should evaluate all important measurement properties, utilising an appropriate framework such as COSMIN to guide study design, to facilitate optimal methodological quality.

Methods for specifying the target difference in a randomised controlled trial: the Difference ELicitation in TriAls (DELTA) systematic review. PLoS Med 2014; 11:e1001645. [PMID: 24824338 PMCID: PMC4019477 DOI: 10.1371/journal.pmed.1001645] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2013] [Accepted: 04/04/2014] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Randomised controlled trials (RCTs) are widely accepted as the preferred study design for evaluating healthcare interventions. When the sample size is determined, a (target) difference is typically specified that the RCT is designed to detect. This provides reassurance that the study will be informative, i.e., should such a difference exist, it is likely to be detected with the required statistical precision. The aim of this review was to identify potential methods for specifying the target difference in an RCT sample size calculation. METHODS AND FINDINGS A comprehensive systematic review of medical and non-medical literature was carried out for methods that could be used to specify the target difference for an RCT sample size calculation. The databases searched were MEDLINE, MEDLINE In-Process, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Methodology Register, PsycINFO, Science Citation Index, EconLit, the Education Resources Information Center (ERIC), and Scopus (for in-press publications); the search period was from 1966 or the earliest date covered, to between November 2010 and January 2011. Additionally, textbooks addressing the methodology of clinical trials and International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) tripartite guidelines for clinical trials were also consulted. A narrative synthesis of methods was produced. Studies that described a method that could be used for specifying an important and/or realistic difference were included. The search identified 11,485 potentially relevant articles from the databases searched. Of these, 1,434 were selected for full-text assessment, and a further nine were identified from other sources. Fifteen clinical trial textbooks and the ICH tripartite guidelines were also reviewed. In total, 777 studies were included, and within them, seven methods were identified-anchor, distribution, health economic, opinion-seeking, pilot study, review of the evidence base, and standardised effect size. CONCLUSIONS A variety of methods are available that researchers can use for specifying the target difference in an RCT sample size calculation. Appropriate methods may vary depending on the aim (e.g., specifying an important difference versus a realistic difference), context (e.g., research question and availability of data), and underlying framework adopted (e.g., Bayesian versus conventional statistical approach). Guidance on the use of each method is given. No single method provides a perfect solution for all contexts.

Abstract
BACKGROUND AND PURPOSE There is no routinely prescribed protocol to address quadriceps weakness and functional impairments following a total knee arthroplasty (TKA). The purpose of this case report is to introduce and describe the early use of a daily adjustable progressive resistance exercise (DAPRE) protocol as an adjunct to standard rehabilitation to maximize quadriceps muscle strength and functional performance in an elderly homebound patient following a TKA. CASE DESCRIPTION A 61-year-old female was referred to home care physical therapy for 6 weeks following left TKA due to functional deficits and inability to activate the weak left quadriceps muscle. In phase I, the patient received three visits with emphasis on edema management, improving left knee range of motion, and reducing pain. Phase II consisted of two main components: (1) a DAPRE protocol aimed at maximizing the quadriceps strength and (2) functional training aimed at improving normal gait patterns, transfers, and dynamic balance. OUTCOMES The patient made substantial improvements in both quadriceps muscle strength and functional performance in the first seven weeks following the TKA. The patient had a pain free return to daily living activities. DISCUSSION The results suggest that early initiation of a DAPRE protocol was free of adverse events and improved quadriceps strength and functional performance for this patient.
