The effectiveness of virtual reality-based exercises in patients with symptomatic knee osteoarthritis: randomized controlled study

OBJECTIVE: The aim of this study was to investigate the effectiveness of adding non-immersive virtual reality-based exercise to a conventional rehabilitation program for pain, functionality, balance, and quality of life in patients with knee osteoarthritis. METHODS: This randomized controlled clinical trial involved 60 patients. Measurements were taken before and after treatment (at week 3). Visual analog scale, Western Ontario and McMaster Universities Osteoarthritis Index, and the Short Form-36 were measured. Postural Stability- Dynamic Overall Stability Index, Functional Reach Composite Score, and Clinical Test of Sensory Interaction on Balance-Composite Score were recorded using the Biodex Balance System. RESULTS: In both groups, statistically significant improvements were observed in visual analog scale, Western Ontario and McMaster Universities Osteoarthritis Index, the Short Form-36 Physical Functioning, Postural Stability-Dynamic Overall Stability Index, Functional Reach Composite Score, and Clinical Test of Sensory Interaction on Balance-Composite Score scores in the post-intervention period (p
