Osteoarthritis is a common rheumatologic disease. Several non operative interventions have been described for the
treatment. But the available evidences of comparing the effectiveness of Virtual reality training over sensory motor
training are very few. So, the purpose of this study is to compare the effectiveness of Virtual reality training over
sensory motor training in the treatment of Osteoarthritis. 60 subjects who fulfilled the inclusion and exclusion
criteria were divided into three Groups (1, 2 & 3) with randomized sampling method. Group 1 treated with Virtual
reality training (VRT), Group 2 treated with sensory motor training (SMT) and Group 3 (control) treated with
conventional exercise training (CET). The duration of the treatment was three times per week for 8 weeks in all the
three groups. Subjects were assessed at baseline, at 4th and 8th week. Pain Intensity by Visual Analog scale (VAS),
Joint Proprioception by Perception Sense, Functional Disability by WOMAC Score, and Quality of Life by HRQOL
score were measured. A statistically significant (p ≤ 0.05) difference between all the 3 groups were noted at the
period of 8 week for pain intensity, joint proprioception, functional disability and quality of life. Group-1 treated
with (VRT) shows more significant improvement in all parameters compared with Group-2 (SMT) and Group-3
(CET). In conclusion, the addition of virtual reality training to conventional training exercises could improve pain
and proprioception which subsequently improve the functional level and quality of life of OA patients.
