Background: The effectiveness of a high level of physical activity in maintaining physical function in patients with hip osteoarthritis has not been adequately examined. Objective: This study aimed to determine whether self-reported physical activity is associated with physical function and walking ability in female patients with hip osteoarthritis. Methods: This was a multicenter cross-sectional study. The dependent variables were the lower-limb range of motion and muscle strength, and walking ability. Self-reported physical activity was assessed according to the guidelines of the Japanese Ministry of Health, Labor, and Welfare. Multiple regression models were used to determine whether physical activity was significantly related to the dependent variables after adjusting for confounding factors (age, body mass index, hip pain, comorbidity, and severity of hip osteoarthritis). Results: A total of 167 participants were included in the study. Physical activity was associated with muscle strength in hip flexion (affected/unaffected, β = 0.18/β = 0.16), abduction (β = 0.19/β = 0.26), knee extension (β = 0.22/β = 0.26), Timed Up-and-Go test (β = -0.16), and 5-m walking time test (β = -0.15). Conclusion: In female patients with hip osteoarthritis, greater physical activity was associated with greater lower extremity muscle strength and walking ability. [ABSTRACT FROM AUTHOR]

Increased physical activity is an effective treatment for knee osteoarthritis that causes knee pain. However, due to the coronavirus disease 2019, noncontact and non-face-to-face interventions have increased, but the quality of evidence supporting their effectiveness remains unclear. The purpose of the study was to assess the quality of evidence of the effects of non-face-to-face and noncontact interventions on knee pain and physical activity in older adults with knee osteoarthritis. A meta-analysis was conducted to determine the effects of different intervention methods (education and exercise). The Cochrane Central Register of Controlled Trials, PubMed, Cumulative Index to Nursing and Allied Health Literature, and Physiotherapy Evidence Database were systematically searched. Four randomized controlled trials were included in the analysis. The meta-analysis demonstrated that the educational intervention group was significantly effective, although supportive evidence was low quality. Educational intervention may be effective, but the effects need to be confirmed by higher quality clinical trials. [ABSTRACT FROM AUTHOR]

Background/Purpose: The purpose of this study was to determine the short-term minimal clinically important differences (MCIDs) in Knee injury and Osteoarthritis Outcome Score (KOOS) after total knee arthroplasty (TKA) using the anchor method. Methods: Scores for each KOOS subscale were calculated preoperatively and 3 and 6 months postoperatively to create receiver operating characteristic curves, and the MCIDs were calculated. Results: The KOOS MCIDs at 3 months after TKA were 6 for symptoms, 10 for pain, 6 for activities of daily living (ADL), 8 for sport/recreation, and 10 for quality of life (QOL). The KOOS MCIDs at 6 months after TKA were 9 for symptoms, 13 for pain, 10 for ADL, 9 for sport/recreation, and 16 for QOL. The areas under the curves were in the range of 0.8–0.9 at both 3 and 6 months after TKA. Conclusion: MCIDs by KOOS subscales were determined and were highly accurate. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to consolidate the level of evidence for the effects of walking training with poles (pole walking; PW) on walking ability using a systematic review and meta‐analysis. Type: Systematic review and meta‐analysis. Literature Survey: Databases including PubMed, Cochrane Library, Physiotherapy Evidence Database (PEDro), Cumulative Index to Nursing and Allied Health Literature databases, and Igaku Chuo Zasshi were searched on June 20, 2021. Methodology: Data from randomized controlled trials (RCTs) comparing the effects of PW with walking without poles and/or other exercise interventions in disease‐specific and aging populations were collected. Data on walking speed, functional mobility, and walking endurance were collected for the meta‐analyses. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated from postintervention means and standard deviations. The PEDro scale was used for assessing the risk of bias, and the Grading of Recommendations Assessment, Development, and Evaluation system was used to determine the quality of evidence. Synthesis: This study included 13 RCTs comprising 750 participants; of these, six RCTs were included in the meta‐analysis. The results showed that moderate‐quality evidence supports the positive effects of PW on walking speed in patients with Parkinson disease (walking speed: SMD = 0.42, 95% CI = 0.04–0.80). In contrast, PW did not significantly improve functional mobility in patients with Parkinson disease and walking speed in older adults. Conclusions: There was moderate‐quality evidence that PW improved walking speed in patients with Parkinson disease. [ABSTRACT FROM AUTHOR]

No previous studies have proposed a clinical prediction rule that analyzes the factors related to the severity of locomotive syndrome. This study developed and assessed a clinical prediction rule for the severity of locomotive syndrome in older adults. A total of 186 patients were assessed using the locomotive syndrome risk test. Classification and regression tree methodologies were used to develop the clinical prediction rule. This study developed three prediction models based on the severity of the locomotive syndrome, of which Model 3 assessed the most severe condition. The following potential predictive factors were measured and entered into each model; single-leg standing time, grip strength, preferred and maximum walking time, and timed up and go test. The single-leg standing test (≤59.4 or >59.4 s) was the best single discriminator for Model 1. Among those with a single-leg standing time >59.4 s, the next best predictor was grip strength (≤37.8 or >37.8 kg). In Model 2, the single-leg standing test was also the best single discriminator (≤12.6 or >12.6 s). Among those with a single-leg standing time ≤12.6, the next best predictor was TUG (≤7.9 or >7.9 s). Additionally, among those with a single-leg standing time >12.6, the next best predictor was single-leg standing time (≤55.3 or >55.3 s). In Model 3, predictive value in Model 2 was the best single discriminator (0 or 1). Among those with 1, the next best predictor was maximum walking time (≤3.75 or >3.75 s). The area under the receiver operating characteristic curves of Models 1, 2, and 3 were 0.737, 0.763, and 0.704, respectively. A clinical prediction rule was developed to assess the accuracy of the models. These results can be used to screen older adults for suspected locomotive syndrome. [ABSTRACT FROM AUTHOR]

Abstract We aimed to investigate the relationship between body compositions and locomotive syndrome in older women and derive body composition cutoff values to evaluate locomotive syndrome severity. In total, 236 women were included in this study. The percentage of body fat and skeletal muscle mass index was measured using multi-frequency bioelectrical impedance analysis. The locomotive syndrome severity (stage 0–3) was determined using the standup test, the two-step test, and a self-administered questionnaire. The receiver operating characteristic curve analysis indicated that the cutoff value for body fat percentage was 33.1% for locomotive syndrome stage 1 in women. This finding may aid in designing exercise and nutritional interventions to prevent locomotive syndrome in older women. [ABSTRACT FROM AUTHOR]

Background: Additional evidence regarding the effectiveness of self-management programs for patients awaiting total knee arthroplasty is required. Objective: The study aimed to determine if self-reported physical activity was related to muscle strength and walking ability in patients with knee osteoarthritis awaiting total knee arthroplasty. Methods: The study included subjects with knee osteoarthritis awaiting total knee arthroplasty (n = 767). Walking ability and bilateral knee muscle strength were measured as dependent variables. Self-report physical activity was assessed based on the guidelines from the Japanese Ministry of Health, Labor and Welfare. Multiple regression models determined if self-reported physical activity was significantly related to dependent variables, after accounting for other related factors. Results: Physical activity was associated with both higher knee flexion (β = −0.09, p =.013) and higher extension (β = −0.09, p =.007) muscle strength on the unaffected side only. In addition, physical inactivity was associated with a lower walking ability level (TUG: β = 0.08, p =.015; 5mWT: β = 0.10, p =.005). Conclusions: These results can help health-services providers develop educational and/or self-management programs to maintain muscle strength on the unaffected side and walking ability in patients awaiting total knee arthroplasty.
