Convergent and Known-Groups Validity and Sensitivity to Change of the Virtual Performance Measure in Patients With Hip and Knee Osteoarthritis: Longitudinal Study

Convergent and Known-Groups Validity and Sensitivity to Change of the Virtual Performance Measure in Patients With Hip and Knee Osteoarthritis: Longitudinal Study

The preoperative LEFS and VPM scores were compared with postoperative scores, and the magnitude of change over time was examined using paired, 1-tailed t test statistics. The analysis of covariance was used to examine the role of age, sex, and severity score on postoperative VPM scores after adjusting for the preoperative level of functional difficulty. Interactions among independent variables were explored.

Effect of Clinic-Based and Asynchronous Video-Based Exercise on Clinic and Psychosocial Outcomes in Patients With Knee Osteoarthritis: Quasi-Experimental Study

Effect of Clinic-Based and Asynchronous Video-Based Exercise on Clinic and Psychosocial Outcomes in Patients With Knee Osteoarthritis: Quasi-Experimental Study

Descriptive statistics of frequency, mean, and SD were used to summarize data, and an independent t test was used to compare patients’ general and clinical characteristics at baseline. A 2-way mixed-model ANOVA with repeated measures on the time points was used to determine the main effects of the two treatment programs (between-subject factor) and time points (within-subject factor) on the outcome parameters.
