Effect of Virtual Reality Based Intervention on Functional Fitness and Quality of Life of Older Population: A Randomized Controlled Trial

This study aims to conduct a randomized control trial, on 60 older age group participants, and perform the functional fitness test based on the protocol developed by Rikli and Jones, before and after the VR intervention. The functional fitness tests include evaluation of upper body strength, lower body strength, cardiorespiratory endurance, upper body flexibility test, lower body flexibility test, balance, agility test. They will be randomly assigned to the intervention group, receiving the VR program, and the control group who will not receive the VR program. The participants in the intervention group will be asked to use the VR device for 15 minutes, twice a week for 6 weeks, along with their daily routine activities. Control group will carry out the daily routine activities, without the intervention. The change in the quality of life (QOL) and happiness, for both control and intervention groups, will be assessed through EuroQol 5 dimensions 3 level questionnaire (EQ-5D-3L), mini version of Chinese happiness Inventory questionnaire, respectively, to filled at recruitment and follow-up after 6 weeks. The effect of the VR programs will be determined by the comparison of performance, for the functional fitness tests before and after the intervention and also, for the differences between the control and intervention groups
