The effect of a group exercise program on functional performance of patients with moderate knee osteoarthritis

Introduction. The aim of this study was to evaluate the effects of a weekly group exercise program on the functional performance of patients with knee osteoarthritis. Material and methods. Patients (aged 51-78 years) with knee osteoarthritis Kellgren-Lawrence grade II-III were included in an exercise program. The exercise sessions were held once-a week, for six months, being supervised by a physical therapist. The scope of the program was to increase the mobility, muscular strength and balance. The physical function outcome was assessed using the Short Physical Performance Battery (SPPB) in two moments - before and after participating in the exercise program. Results. All patients completed the group exercise program. The SPPB score at the time of inclusion in the study was 8.33 +/- 1.9. After six months of exercising in the weekly group exercise program, the score increased significantly at 9.07 +/- 1.73 (p<0.0001). Conclusions. In conclusion, participating in a group-based exercise program for six months have been proved to have beneficial outcomes in physical performance in patients with knee osteoarthritis.
