Background: To evaluate the effectiveness of isokinetic resistance training and aerobic walking in the patients with knee osteoarthritis on the basis of isokinetic strength (peak torque), pain and functional abilities. Methods: Thirty volunteers (N= 30), ages 40 to 65 years. Patients were randomly assigned to 3 groups: control (n= 10), isokinetic training group (n= 10) and aerobic walking group (n= 10). Subjects in the intervention groups underwent Isokinetic resistance training and aerobic walking for 12 weeks, 2 times per week, whereas subjects in control group underwent isokinetic testing at pre, mid and post test together with the intervention groups. Randomized Control Trial with repeated measure ANOVA was used. Results: There was signifi cant improvement (p<0.05) of peak torque in both intervention groups compared to control group. There was no signifi cant different (p>0.05) between the control and intervention groups in terms of pain score. In terms of physical function on the basis of WOMAC osteoarthritis index subscale, there was a signifi cant improvement (p<0.05) in both the intervention groups at mid and post test compared to the control group. Conclusions: The results suggest that with the isokinetic resistance training and aerobic walking used in this study, it is possible to improve muscle strength and physical function in patients with OA of the knee. The results also showed that extensive training involving a high number of repetitions and concentric contractions was safe, effective, and well tolerated for the patients with knee osteoarthritis.
