Exercise compared to a control condition or other conservative treatment options in patients with Greater Trochanteric Pain Syndrome: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: To estimate the effectiveness of exercise at end of treatment and long-term follow-up compared to a control condition or other conservative treatments in patients with Greater Trochanteric Pain Syndrome (GTPS). METHODS: Databases were searched September 2021 and updated September 2023. Randomized controlled trials (RCT) comparing exercise interventions for patients with GTPS, to a control condition; corticosteroid injection; shock wave therapy; or other types of exercise programs were included. Risk of bias was assessed using the ROB2 tool. Meta-analyses were performed using a random-effects model. The certainty of the evidence was rated by the GRADE approach. RESULTS: Six RCTs including a total of 733 patients with GTPS were included. Three trials compared exercise to sham exercise or wait-and-see control groups, two trials compared exercise to corticosteroid injection, two trials compared exercise to shockwave therapy, and one trial compared exercise to another type of exercise. Meta-analyses showed that in the long term, exercise slightly reduces hip pain and disease severity, while slightly improving patient-reported physical function and global rating of change compared to a control condition. No serious adverse events were reported. Compared to corticosteroid injection, exercise improves long-term global rating of change. CONCLUSION: The current evidence supports a strong recommendation for exercise as first line treatment in patients clinically diagnosed with GTPS. Compared to corticosteroid injection, exercise is superior in increasing the likelihood that a patient experiences a meaningful global improvement. These results are based on few trials and a moderate number of patients. REGISTRATION: This review was prospectively registered in the PROSPERO database of systematic reviews (ID: CRD42021261380).

Extracorporeal Shockwave Therapy With a Modified Technique on Tendon and Ligament for Knee Osteoarthritis: A Randomized Controlled Trial.

BACKGROUND: There have been no definitive guidelines on the treatment method and specific points in the body. PURPOSE: The aim of the study was to investigate the effects of extracorporeal shockwave therapy on treating the main tendons and ligaments of knee osteoarthritis. METHOD: A total of 36 patients with knee osteoarthritis were enrolled in trial and organized into two groups: 3-wk extracorporeal shockwave therapy for the intervention group and 3-wk sham extracorporeal shockwave therapy for control group. Both groups received the same physical therapies: (1) transcutaneous electrical nerve stimulation, (2) magnetic field treatment, and (3) quadricep muscle strength training. Evaluation was performed before the start of treatment, at third week after the start of treatment, and 1 wk after the end of treatment. The study used randomized controlled trials (level of evidence, 1). RESULT: Eextracorporeal shockwave therapy group had significant improvement in WOMAC pain score, physical function, and total score (mean difference = -2.8, P < 0.001; -5.1, P = 0.02; -8.3, P = 0.004, respectively), Visual Analog Scale score (mean difference = -2.3, P < 0.001), and the distance of 6-min walk test (mean difference = 28.7, P = 0.01) in the 1 wk after the end of treatment. Statistical significance in WOMAC pain, physical function, and total scores (mean difference = -3.0, P = 0.001; -5.6, P = 0.02; -9.3, P = 0.004, respectively) and Visual Analog Scale score (mean difference = -1.2, P = 0.027) was observed between the extracorporeal shockwave therapy group and control group. CONCLUSIONS: Extracorporeal shockwave therapy for the tendons and ligaments has clinical benefits for pain and physical function improvement in knee osteoarthritis. In addition, improvement in physical performance was observed in the short-term follow-up.

The Relationship Between Changes in Movement and Activity Limitation or Pain in People With Knee Osteoarthritis: A Systematic Review.

OBJECTIVE: To report whether changes in knee joint movement parameters recorded during functional activities relate to change in activity limitation or pain after an exercise intervention in people with knee osteoarthritis (OA). DESIGN: Etiology systematic review. LITERATURE SEARCH: Four databases (MEDLINE, Embase, CINAHL, and AMED) were searched up to January 22, 2021. STUDY SELECTION CRITERIA: Randomized controlled trials or cohort studies of exercise interventions for people with knee OA that assessed change in knee joint movement parameters (moments, kinematics, or muscle activity) and clinical outcomes (activity limitation or pain). DATA SYNTHESIS: A descriptive synthesis of functional activities, movement parameters, and clinical outcomes. RESULTS: From 3182 articles, 22 studies met the inclusion criteria, and almost all were of low quality. Gait was the only investigated functional activity. After exercise, gait parameters changed 26% of the time, and clinical outcomes improved 90% of the time. A relationship between group-level changes in gait parameters and clinical outcomes occurred 24.5% of the time. Two studies directly investigated an individual-level relationship, reporting only 1 significant association out of 8 correlations tested. CONCLUSION: Most studies reported no change in gait-related movement parameters despite improvement in clinical outcomes, challenging the belief that changing movement parameters is always clinically important in people with knee OA.

Does the Spraino low-friction shoe patch prevent lateral ankle sprain injury in indoor sports? A pilot randomised controlled trial with 510 participants with previous ankle injuries.

BACKGROUND: Lateral ankle sprains are common in indoor sports. High shoe-surface friction is considered a risk factor for non-contact lateral ankle sprains. Spraino is a novel low-friction patch that can be attached to the outside of sports shoes to minimise friction at the lateral edge, which could mitigate the risk of such injury. We aimed to determine preliminary effectiveness (incidence rate and severity) and safety (harms) of Spraino to prevent lateral ankle sprains among indoor sport athletes. METHODS: In this exploratory, parallel-group, two-arm pilot randomised controlled trial, 510 subelite indoor sport athletes with a previous lateral ankle sprain were randomly allocated (1:1) to Spraino or 'do-as-usual'. Allocation was concealed and the trial was outcome assessor blinded. Match and training exposure, number of injuries and associated time loss were captured weekly via text messages. Information on harms, fear-of-injury and ankle pain was also documented. RESULTS: 480 participants completed the trial. They reported a total of 151 lateral ankle sprains, of which 96 were categorised as non-contact, and 50 as severe. All outcomes favoured Spraino with incidence rate ratios of 0.87 (95% CI 0.62 to 1.23) for all lateral ankle sprains; 0.64 (95% CI 0.42 to 0.98) for non-contact lateral ankle sprains; and 0.47 (95% CI 0.25 to 0.88) for severe lateral ankle sprains. Time loss per injury was also lower in the Spraino group (1.8 vs 2.8 weeks, p=0.014). Six participants reported minor harms because of Spraino. CONCLUSION: Compared with usual care, athletes allocated to Spraino had a lower risk of lateral ankle sprains and less time loss, with only few reported minor harms.

Immediate Effect of Ankle Mobilization on Range of Motion, Dynamic Knee Valgus, and Knee Pain in Women With Patellofemoral Pain and Ankle Dorsiflexion Restriction: A Randomized Controlled Trial With 48-Hour Follow-Up.

CONTEXT: Restriction in ankle dorsiflexion range of motion (ROM) has been previously associated with excessive dynamic knee valgus. This, in turn, has been correlated with knee pain in women with patellofemoral pain. OBJECTIVES: To investigate the immediate effect of 3 ankle mobilization techniques on dorsiflexion ROM, dynamic knee valgus, knee pain, and patient perceptions of improvement in women with patellofemoral pain and ankle dorsiflexion restriction. DESIGN: Randomized controlled trial with 3 arms. SETTING: Biomechanics laboratory. PARTICIPANTS: A total of 117 women with patellofemoral pain who display ankle dorsiflexion restriction were divided into 3 groups: ankle mobilization with anterior tibia glide (n = 39), ankle mobilization with posterior tibia glide (n = 39), and ankle mobilization with anterior and posterior tibia glide (n = 39). INTERVENTION(S): The participants received a single session of ankle mobilization with movement technique. MAIN OUTCOME MEASURES: Dorsiflexion ROM (weight-bearing lunge test), dynamic knee valgus (frontal plane projection angle), knee pain (numeric pain rating scale), and patient perceptions of improvement (global perceived effect scale). The outcome measures were collected at the baseline, immediate postintervention (immediate reassessment), and 48 hours postintervention (48 h reassessment). RESULTS: There were no significant differences between the 3 treatment groups regarding dorsiflexion ROM and patient perceptions of improvement. Compared with mobilization with anterior and posterior tibia glide, mobilization with anterior tibia glide promoted greater increase in dynamic knee valgus (P = .02) and greater knee pain reduction (P = .02) at immediate reassessment. Also compared with mobilization with anterior and posterior tibia glide, mobilization with posterior tibia glide promoted greater knee pain reduction (P < .01) at immediate reassessment. CONCLUSION: In our sample, the direction of the tibia glide in ankle mobilization accounted for significant changes only in dynamic knee valgus and knee pain in the immediate reassessment.

Effects of technology-supported exercise programs on the knee pain, physical function, and quality of life of individuals with knee osteoarthritis and/or chronic knee pain: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: The study sought to examine the effects of technology-supported exercise programs on the knee pain, physical function, and quality of life of individuals with knee osteoarthritis and/or chronic knee pain by a systematic review and meta-analysis of randomized controlled trials. MATERIALS AND METHODS: We searched MEDLINE, EMBASE, CINAHL Plus, and the Cochrane Library from database inception to August 2020. A meta-analysis and subgroup analyses, stratified by technology type and program feature, were conducted. RESULTS: Twelve randomized controlled trials were reviewed, all of which implemented the programs for 4 weeks to 6 months. Telephone, Web, mobile app, computer, and virtual reality were used to deliver the programs. The meta-analysis showed that these programs were associated with significant improvements in knee pain (standardized mean difference [SMD] = -0.29; 95% confidence interval [CI], -0.48 to -0.10; P = .003) and quality of life (SMD = 0.25; 95% CI, 0.04 to 0.46; P = .02) but not with significant improvement in physical function (SMD = 0.22; 95% CI, 0 to 0.43; P = .053). Subgroup analyses showed that some technology types and program features were suggestive of potential benefits. CONCLUSIONS: Using technology to deliver the exercise programs appears to offer benefits. The technology types and program features that were associated with health values have been identified, based on which suggestions are discussed for the further research and development of such programs.

The Effect of the Powerball Gyroscope as a Treatment Device for Nonspecific Wrist Pain.

OBJECTIVE: The aim of this study was to determine the effect of using the Powerball gyroscope as a treatment device on pain and change in endurance in nonspecific wrist pain. METHODS: This study was a within-participants pre- and postintervention study consisting of 40 participants between ages 18 and 35 with an equal male-to-female ratio. The participants used the Powerball gyroscope for 5 minutes per treatment session. Treatment comprised 12 sessions carried out 3 × per week over a 4-week period. Participants completed objective and subjective data before the first, seventh, and 12th sessions. Objective data were recorded using the Jamar dynamometer to measure grip strength. Subjective data were gathered using the Patient-Rated Wrist Evaluation Questionnaire. Participants then used the Powerball gyroscope in the hand with the affected wrist. The Wilcoxon signed rank test and 1-way repeated-measures analysis of variance were used to analyze the changes. RESULTS: A significant decrease in pain was noted throughout the study, but the most significant changes occurred between the seventh and 12th treatment sessions (P < .01). A significant increase in grip strength was also noted throughout the study, with the greater increase in grip strength occurring during the first 7 treatments (P < .02). CONCLUSION: The Powerball gyroscope showed a change in outcome regarding nonspecific wrist pain and grip strength.

Effectiveness of supervised resistance training for patients with hip osteoarthritis - a systematic review.

INTRODUCTION: The overall effectiveness of supervised progressive resistance training among patients with hip osteoarthritis is only scarcely investigated. The objective of this study was to estimate the effectiveness of supervised progressive resistance training compared with common treatment for patients with hip osteoarthritis, focusing on patient-reported function, pain, health-related quality of life, performance-based function at end of treatment and patient-reported function at 6-12 months. METHODS: This was a systematic review and meta-analysis. A systematic search was performed on 30 January 2019 in eight electronic databases (Medline, Embase, Cochrane, Pedro, AMED, Scopus, SPORTDiscus and Cinahl). The methodology of the included studies and the overall quality of evidence was assessed using the Cochrane Risk of Bias tool and the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: A total of 189 participants with hip osteoarthritis > 50 years of age were included in the three studies. A significant difference in favour of the supervised progressive resistance groups was found in patient-reported function (weighted mean difference (MD) = 9.13 (95% confidence interval (CI): 4.45-13.80)), hip-related pain (weighted MD = 7.83 (95% CI: 2.64-13.02)) and health-related quality of life (weighted MD = 6.80 (95% CI: 1.96-11.63)) at end of treatment. The overall quality of evidence was downgraded to low due to a lack of blinding in the included studies and due to imprecision. CONCLUSIONS: Supervised progressive resistance training might be of clinical relevance for patients with hip osteoarthritis and was effective in improving patient-reported function, hip-related pain and health-related quality of life. The level of evidence is low and future studies may therefore affect the findings reported herein.

Hip-Joint Posture and Movement Alterations Are Associated With High Interference of Pain in the Life of Patients With Greater Trochanteric Pain Syndrome.

OBJECTIVE: Greater trochanteric pain syndrome (GTPS) is a common condition that can cause lateral hip pain. The single-leg-squat test (SLST) may be used by physicians in primary care environments to evaluate patients' dynamic stability. The aim of this study was to evaluate the dynamic stability and strength of lateral abduction hip movements in primary care patients with GTPS in relation to their perceived pain interference in life. METHODS: A descriptive observational study was carried out in a primary health care center. Fifty-four participants with GTPS were included in this study and divided into lower- and higher-interference groups (n = 30 and 19, respectively) according to the Graded Chronic Pain Scale. Participants were evaluated for their lateral abduction hip strength and the SLST. RESULTS: The SLST showed a statistically significant difference between groups with respect to hip-joint posture and movement level (P = .043) but not for other SLST domains or lateral abduction hip strength (P > .05). CONCLUSION: Patients with GTPS with more pain interference in their lives had poorer dynamic stability with respect to hip-joint posture and movements based on the SLST but did not present impaired lateral hip abduction strength in comparison with those who perceived lower pain interference in life.

Individualized predictions of changes in knee pain, quality of life and walking speed following patient education and exercise therapy in patients with knee osteoarthritis - a prognostic model study.

OBJECTIVE: To facilitate shared decision-making for patients with knee osteoarthritis (OA), we aimed at building clinically applicable models to predict the individual change in pain intensity (VAS scale 0-100), knee-related quality of life (QoL) (KOOS QoL score 0-100) and walking speed (m/sec) immediately following two educational and 12 supervised exercise therapy sessions. METHODS: We used data from patients with knee OA from the 'Good Life with osteoArthritis in Denmark' (GLA:D®) registry (n = 6,767). From 51 patient characteristics, we selected the best performing variables to predict the outcomes via random forest regression. We evaluated model performance via R2. Lastly, we validated and compared our models with the average improvements via the mean differences in an independent validation data set from the GLA:D® registry (n = 2,896) collected 1 year later than the data used to build the models. RESULTS: Validating our models including the best performing variables yielded R2s of 0.34 for pain intensity, 0.18 for knee-related QoL, and 0.07 for walking speed. The absolute mean differences between model predictions and the true outcomes were 14.65 mm, 10.32 points, and 0.14 m/s, respectively, and similar to the absolute mean differences of 17.64, 11.28 and 0.14 observed when we subtracted the average improvements from the true outcomes. CONCLUSION: Despite including 51 potential predictors, we were unable to predict changes in individuals' pain intensity, knee-related QoL and walking speed with clinically relevant greater precision than the respective group average outcomes. Therefore, average prediction values can be used to inform patients about expected outcomes.

Improving function in people with hip-related pain: a systematic review and meta-analysis of physiotherapist-led interventions for hip-related pain.

OBJECTIVE: To report the effectiveness of physiotherapist-led interventions in improving pain and function in young and middle-aged adults with hip-related pain. DESIGN: Systematic review and meta-analysis. DATA SOURCES: A comprehensive, reproducible search strategy was performed on five databases in May 2019. Reference lists and grey literature were also searched. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Population: people aged ≥18 years with hip-related pain (with or without a diagnosis of femoroacetabular impingement syndrome). INTERVENTION(S): physiotherapist-led interventions for hip pain. Comparators: sham treatment, no treatment or other treatment (eg, hip arthroscopic surgery). OUTCOMES: primary outcomes included patient-reported hip pain and function. Secondary outcomes included physical function measures. RESULTS: 1722 papers were identified. After exclusion criteria were applied, 14 studies were included for analysis. They had varied risk of bias. There were no full-scale placebo-controlled randomised controlled trials (RCTs) of physiotherapist-led treatment. Pooled effects ranged from moderate effects (0.67 (95% CI 0.07 to 1.26)) favouring physiotherapist-led intervention over no treatment post-arthroscopy, to weak effects (-0.32 (95% CI 0.57 to 0.07)) favouring hip arthroscopy over physiotherapist-led treatment. CONCLUSION: Physiotherapist-led interventions might improve pain and function in young and middle-aged adults with hip-related pain, however full-scale high-quality RCT studies are required.

Contralateral canes for knee osteoarthritis. / Uso de bastones contralaterales en artrosis de rodilla.

INTRODUCTION: Knee osteoarthritis is a relevant health problem given its high prevalence and associated disability. Within the non-pharmacological management alternatives, the use of canes has been proposed, however, there is no consensus in the literature regarding its indication. METHODS: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified three systematic reviews including four studies overall, of which one was randomized trials. We conclude that the use of a contralateral cane in patients with knee osteoarthritis probably reduces pain. In addition, it could slightly increase function, but the certainty of the evidence is low.

INTRODUCCIÓN: La artrosis de rodilla es un problema de salud relevante dada su alta prevalencia y discapacidad asociada. Dentro de las alternativas de manejo no farmacológico se ha planteado el uso de bastones, sin embargo no existe consenso en la literatura respecto a su indicación. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis, preparamos tablas de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos tres revisiones sistemáticas que en conjunto incluyeron cuatro estudios primarios, de los cuales, uno es ensayo aleatorizado. Concluimos que el uso de bastón contralateral en pacientes con artrosis de rodilla probablemente disminuye el dolor. Además, podría aumentar levemente la funcionalidad, pero la certeza de la evidencia es baja.

A single-arm, non-randomized investigation into the short-term effects and follow-up of a 4-week lower limb exercise programme on kinesiophobia in individuals with knee osteoarthritis.

OBJECTIVE: To investigate the short-term effects and follow-up of a 4-week lower limb exercise programme on kinesiophobia in individuals with knee osteoarthritis (OA). DESIGN: Participants diagnosed with knee OA clinically against the American College of Rheumatology criteria were recruited. Participants completed a 4-week lower limb exercise programme. Each participant completed two questionnaires, the Tampa Scale of Kinesiophobia and the Knee Injury and OA Outcome Score. Each measurement was completed at the baseline assessment, at Session 4 of the programme, at Session 8 of the programme, and 6 weeks after the exercise programme. Perceived levels of exertion rate of perceived exertion were measured after each exercise session using the modified Borg scale. RESULTS: Fifty-four participants took part in the study. Kinesiophobia decreased from the baseline assessment to 6 weeks after the exercise programme. KOOS pain, symptoms, sports and recreation, quality of life and activities of daily living score increased, therefore showed improvement. Correlational analysis highlighted a moderate negative correlation between the KOOS pain and kinesiophobia at baseline and 6 weeks after the exercise programme (0.44 and 0.48 respectively). CONCLUSIONS: Understanding baseline kinesiophobia scores could provide an important resource for health professionals who manage individuals with knee OA to improve the quality of care due to the correlation with pain changes and may improve exercise-related outcomes for a longer duration. HIGHLIGHTS: Kinesiophobia is prevalent in individuals diagnosed with knee osteoarthritis (OA). Kinesiophobia decreased in 75% of individuals with knee OA after a 4-week exercise programme. Correlation between pain and kinesiophobia at baseline and 6 weeks after an exercise programme. An understanding of an individual's kinesiophobia level before an exercise programme is important for future prognosis of changes in pain. CLINICAL TRIAL NUMBER: NCT02734342.

Effect of Body Weight-Supported Exercise on Symptoms of Knee Osteoarthritis: A Follow-up Investigation.

OBJECTIVE: To examine the long-term effect of participation in a 12-week lower-body positive pressure (LBPP)-supported low-load treadmill exercise regime on knee joint pain, physical function, and thigh muscle strength in patients with knee osteoarthritis (OA). DESIGN: Prospective, observational, repeated measures. SETTING: Clinical orthopedic setting. PATIENTS: Nineteen overweight patients with knee OA. INTERVENTION: Participants exercised under low-load treadmill walking conditions 2×/week for 12 weeks using an amount of LBPP support that minimized knee pain while walking for a period of 30 minutes at a set speed of 3.1 mph at 0-degree incline. MAIN OUTCOME MEASURES: Knee pain, function, thigh muscle strength, and body anthropometry were reassessed a minimum of 6 months after completion of the initial exercise regime and compared with results from baseline and postexercise evaluation. RESULTS: Data suggested that: (1) patients were able to maintain improvements in knee joint pain and symptoms; (2) patients continued to report enhanced joint function and improved quality of life; and (3) patients maintained thigh muscle strength gains. Finally, a majority of patients continued to experience significant reductions in acute knee pain during full weight-bearing treadmill walking. CONCLUSIONS: Data suggest that improvements in knee pain, joint function, and thigh muscle strength associated with participation in a 12-week LBPP-supported low-load exercise regime were maintained well after cessation of the program. These findings have important implications for the development and refinement of exercise strategies and interventions used in the long-term management of joint symptoms associated with knee OA in overweight patients.

The impact of progressive pelvic floor muscle exercise and manual therapy in a patient postpartum who met the criteria for sacroiliac joint pain based on Laslett's cluster of provocation signs.

Sacroiliac joint (SIJ) pain has been identified as a primary or contributing source of pain in patients with low back pain. The Laslett cluster of SIJ pain provocation tests has the strongest evidence for noninvasive clinical testing. The purpose of this report was to describe the impact of physical therapy treatments for a patient postpartum with SIJ pain who satisfied the Laslett cluster. Specifically, the goal was to assess the impact of progressive pelvic floor muscle exercise and manual therapy. The Modified Oswestry Low Back Pain Disability Questionnaire (MODI) was the primary outcome measure used in this case. In addition, the Numeric Pain Rating Scale (NRPS) and Global Rating of Change (GROC) were used as secondary outcome measures. In this case report, the patient responded to the combined interventions with decreases in MODI, NRPS and GROC. Further research is warranted to develop stronger evidence to identify specific interventions for the treatment of SIJ pain.

SMoC-Wrist: a sensorimotor control-based exercise program for patients with chronic wrist pain.

STUDY DESIGN: This is a narrative review. INTRODUCTION: Chronic wrist pain is a common disorder that can lead to considerable disability in performing activities in daily living and at work. Patients with nonspecific chronic wrist pain are regularly referred to a physiotherapist/hand therapist. Immobilization, avoiding excessive wrist load, steroid injections, and various physical therapy methods predominantly focus on the pain itself. However, these methods often do not result in a satisfactory long-term pain relief. PURPOSE OF THE STUDY: In this article, we will describe the principles behind and content of a sensorimotor control-based exercise program as introduced by Videler et al., modified and substantiated by current insights into sensorimotor control training and wrist kinetics. METHODS: Both structure and content of the modified exercise program (SMoC-wrist) are substantiated by recent scientific literature. RESULTS: A clear 4-level exercise model based on sensorimotor principles is presented, that is, proprioceptive level, conscious static/isometric level, conscious dynamic level, and unconscious dynamic level. The content of each level and the transition toward the next level are described in detail. DISCUSSION: Besides the substantiation of the exercise program, possible outcome measures for joint position sense and kinesthesia of the wrist are discussed. CONCLUSION: We modified and substantiated a widely used exercise program for patients with nonspecific chronic wrist pain based on recent insights into sensorimotor control principles and wrist kinematics. The presented exercise program (SMoC-wrist) is not primarily focused on reducing pain but on functional reeducation and strengthening of the neuromusculoskeletal system on the basis of sensorimotor control principles.

Hip Muscle Strengthening for Knee Osteoarthritis: A Systematic Review of Literature.

BACKGROUND AND PURPOSE: Osteoarthritis (OA) of the knee joint results in chronic pain and functional decline among older adults. Hip muscle weakness has been observed in persons with knee OA and is claimed to increase the medial compartment loading on the knee joint. Although individual studies are available, no review has yet integrated the literature on the benefits of hip muscle strengthening for persons with knee OA. This review aims to systematically summarize the current evidence on the effectiveness of hip muscle strengthening on knee pain, lower extremity function, and biomechanical measures of the knee in persons with knee OA. METHODS: An extensive electronic literature search was conducted in the databases PubMed, Scopus, Cumulative Index to Nursing and Allied Health (CINAHL), Cochrane Central Register of Controlled Trials (CENTRAL), and Physiotherapy Evidence Database (PEDro) to identify the published trials in the English language from January 1990 to August 2017. Randomized controlled trials that studied the effectiveness of hip muscle strengthening in persons with knee OA on knee pain, physical function, and biomechanical measures of the knee were considered for inclusion. The key word combinations were knee osteoarthritis, degenerative arthritis, arthralgia, muscle strengthening, and resistance training using the Boolean operators AND, OR. Two reviewers independently performed the study selection, and a third reviewer intervened when the consensus was not attained. Quality assessment of the included studies was carried out using the PEDro scale. RESULTS AND DISCUSSION: The search produced 774 results, from which 81 full-text articles were studied. Five randomized controlled trials of good methodological quality, including 331 participants, were included in the review. The effectiveness of hip muscle strengthening was assessed in isolation, combination, and comparison with other lower extremity exercise. Overall, the studies reported clear benefits of hip muscle strengthening on knee pain, physical function, and hip muscle strength. However, hip muscle strengthening was ineffective in improving the biomechanical measures such as dynamic alignment and knee adduction (also known as valgus) moment. CONCLUSION: The current review identified strong, high-quality evidence to recommend hip muscle strengthening in the conservative management of persons with knee OA. Further research is needed to establish the underlying mechanisms for the clinical benefits.
