Abstract

The aim of this study was to evaluate effects of electrical stimulation combined with continuous passive motion (CPM–ES) versus isometric exercise on symptoms, functional capacity, quality of life, muscle strength, knee and thigh circle measurements, and balance in knee osteoarthritis (OA). This is a randomized clinical trial. The study was done in Gulhane Military Medical Academy (GMMA) Rehabilitation Center. Forty patients with knee OA were included in this study. Participants were randomly assigned to two groups: 20 patients placed in Group 1 were treated with conventional physical therapy and CPM–ES combination; 20 patients in Group 2 were treated with conventional physical therapy and isometric exercise. Therapies were applied 3 weeks, 5 days per week. The following main outcome measures were done: values of pain (VAS was used), WOMAC, SF-36, knee and thigh circle measurements, isokinetic tests, dynamic and static balance tests were determined at baseline and after the treatment. There were no statistically significant differences in the tested variables between the groups for post-treatment values. Dynamic and static balance test improved statistically strongly significantly in both groups. The findings of this study demonstrate that knee OA patients could improve their balance function in both static and dynamic conditions after CPM–ES combination or isometric exercise therapy. The improvement might prevent knee OA patients from falling down and increase their sense of security during physical activities.
