Riassunto dello studio

Thirty-six women 60 years old or older with radiographically confirmed knee osteoarthritis and Kellgren-Lawrence grade 1 or 2 were randomized 1:1 to either a home-based remote-rehabilitation program (using the exoRehab wearable biofeedback device) or a no-intervention control group. After withdrawals, 15 participants in the experimental group and 16 in the control group completed baseline and 8-week assessments. Overall, the results of the study revealed that remote rehabilitation significantly improved the five-times sit-to-stand test (FTSST) performance relative to control, and within-group gains were observed across timed up-and-go (TUG), knee flexor strength, right-side quadriceps activation, and systolic/diastolic blood pressure. The control group showed only a modest reduction in pain scores. These findings suggest that home-based remote rehabilitation can serve as a viable alternative to supervised exercise for improving physical function in older women with knee osteoarthritis.
