The conservative techniques of treating knee osteoarthritis (kOA) include wearing orthoses such as knee braces and laterally wedged insoles and applying gait modification techniques such as toe-in gait and toe-out gait. This study aimed at assessing the immediate effects of these techniques in improving physical function of healthy and kOA participants. Five Osteoarthritis Research Society International (OARSI) recommended performance-based tests were randomly applied to measure physical function: (1) 30-second chair stand test (30CST), (2) 40-m (4 × 10) fast-paced walk test (40FPW), (3) stair climb test (SCT), (4) timed up and go test (TUGT) and (5) 6-minute walk test (6MWT) during a single-visit on 20 healthy and 20 kOA patients (age: 59.5 ± 7.33 and 61.5 ± 8.63 years, BMI: 69.95 ± 9.86 and 70.45 ± 8.80 kg/m2). The interventions included natural gait, toe-out gait, toe-in gait, laterally wedged insoles and knee brace. Analysis was performed through repeated-measures ANOVA and independent sample t-test. 30CST and TUGT showed no significant differences for the five test conditions ( p > 0.05). Toe-out showed profound effects via pairwise comparison in impairing the physical function while knee brace improved it during 40FPW, SCT and 6MWT. In general, all the tested conservative techniques except laterally wedged insoles had immediate effects on physical performance measures in both healthy and medial knee osteoarthritis participants. The valgus knee brace improved the parameters the most, while toe-out gait impaired them the most. Future studies can develop strategies for improving gait retraining methods on the basis of issues identified by this study.

Abstract Background and Purpose. This cross-sectional study evaluated the relative contributions of psychosocial and mechanical variables to physical performance measures in people with knee osteoarthritis (OA). Subjects. Fifty-four subjects (age, in years: X̄=68.3, SD=8.7, range=50–87) with radiographically confirmed knee OA were included in this study. Methods. Physical performance measures included the Six-Minute Walk Test (SMW), the Timed “Up & Go” Test (TUG), and a stair-climbing task (STR). Responses to psychosocial questionnaires that reflect depression, anxiety, and self-efficacy (a person's confidence in his or her ability to complete a task) were collected. Mechanical variables measured included body mass index and knee strength (force-generatingcapacity of muscle). Stepwise linear regressions were performed with the SMW, TUG, and STR as separate dependent variables. Results. Functional self-efficacy explained the greatest amount of variance in all performance measures, contributing 45% or more. Knee strength and body weight also explained some variance in performance measures. Anxiety and depression did not explain any variance in performance. Discussion and Conclusion Physical therapists evaluating the significance of the SMW, TUG, and STR scores in subjects with knee OA should note that a large part of each score reflects self-efficacy, or confidence, for physical tasks, with some contributions from knee strength and body weight.

Introduction: Patients with symptoms (Sx) of gastrointestinal (GI) motor disorders have limitations in physical strength and mobility. We hypothesized that physical frailty correlated with severity of GI symptoms, and that a motility frailty index (MFI) could be constructed. Patients: We conducted a prospective pilot study on 40 patients, (38 F, 2 M, mean age 39.9 years) with the following diagnoses: 10 with diabetes mellitus and 30 with non-diabetic/idiopathic disorders. Upper and lower GI Sx were quantified using an FDA-compliant, traditional patient-reported outcomes (PRO) system. Methods: Patients underwent a series of physical performance measures involving standing balance (SB), usual walk speed (UW), and chair sit-and-stands (CS). A GI motility frailty index (MFI) was constructed by fitting several models with a combination of physical performance measures and correlating with PRO. Pearson’s correlation compared the constructed index with the GI Sx PRO to construct a GI MFI. Results: The studied patients collectively showed marked limitations in mobility compared with standard performance values with mean (sd) ratios of SB = 0.87 (0.20), UW = 0.45 (0.13), and CS = 0.38 (0.17). Correlations between physical mobility and GI Sx were noted for upper GI Sx (rho = 0.47, p = 0.002) but not for lower GI Sx. Conclusions: In this pilot study of patients with GI motility disorders, we found increased physical limitations on performance-based testing, which had a statistically significant positive correlation with severity of upper GI motor Sx using a standardized PRO system. A motility frailty index has been constructed that may serve as a basis for better quantifying limitations in patient mobility.

The goal of this study was to identify methods for characterizing high-functioning older adults living in the community. The subjects were 495 older adults from the Longitudinal Interdisciplinary Study on Aging conducted by the Tokyo Metropolitan Institute of Gerontology. Physical performance measures included grip strength, walking at preferred and maximum speeds, one-leg standing with eyes open, and finger tapping rate. Performance scores were created by summing each categorical score. Consistent differences were found among age groups and genders. Scores were lower in subjects who had stroke or diabetes than in those without these conditions. These results suggest that physical performance measures have both discriminant validity and construct validity, which make them useful methods for characterizing high-functioning older persons.
