Effects of Therapeutic Exercise on Patients with Osteoarthritis of Knee

ABSTRACT

OBJECTIVE: To investigate the effect of therapeutic exercise on patients with osteoarthritis of knee in view of functional capacity. METHOD: The subjects were 80 patients with osteoarthritis of knee. Patients were randomly allocated to exercise or no exercise (control) group. Osteoarthritis was diagnosed on the base of clinical features, X ray findings. Therapeutic exercise was consisted of quad-setting exercise, isokinetic exercise, squatting exercise. Effects of therapeutic exercise were evaluated by muscle function, functioal performance and degree of pain. RESULTS: In exercise group, muscle function such as torque and endurance of extensor and flexor of knee were increased significantly compaired with control group (p<0.05). Increment was more apparent in extensor. In both group, pain was decreased but more apparent in exercise group (p<0.05). Functional performance was assessed in terms of dependency, difficulty and amount of pain. Exercise group showed improvement of functional performance in walking inside, climbing stairs (p<0.05) but control group did not show improvement. Seventy percent of patients with osteoarthritis of knee showed increment of body weight above 10 kg compaired with their twenties. CONCLUSION: When we manage the osteoarthritis of knee, therapeutic exercise should be included in the treatment regimen as well as physical and medical therapy.
