Objectives: The purpose of this study is to investigate the effects of virtual reality game-based exercises on pain, functional mobility, and balance in knee osteoarthritis patients. Materials and Methods: Fifty patients(5 males and 45 females) having idiopathic knee osteoarthritis were included and divided into two groups as the control and study. For each patient, the knee which had the higher visual analog scale (VAS) value was evaluated. The same knee’s active flexion and extension range of motion values were recorded. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) total score and Community Balance and Mobility Scale (CB&M) score were also recorded for each patient. In the control group, patients received conventional physiotherapy and knee OA exercises, whereas the study group received game-based exercises in addition to the treatment applied in the control group. Both groups received 15 sessions of treatment for three weeks, then the same measurements which were performed at the beginning of the study were repeated for each patient.Results: At the end of the treatments, significant differences was found between two groups for VAS, WOMAC total and CB&M scores (p<0.05), whereas there were no significant differences for theactive flexion and extension range of motion values (p>0.05).Conclusions: Adding virtual reality game-based exercises to the treatment program in knee osteoarthritis may produce more beneficial results for patients.
