OBJECTIVE: To assess the effects of an unsupervised virtual reality (VR)-based exercise program on hip muscles strength and balance control in the elderly. DESIGN: Controlled cohort repeated-measures experimental design, a pilot study SETTING: University research laboratory PARTICIPANTS: Thirty-two ambulatory older adults from a local community INTERVENTION: The VR group (n = 18; mean ± standard deviation [SD], 68.28 ± 3.74 yr; four males) completed the VR-based exercise program, whereas the remaining subjects in the control group (n = 14; mean ± SD, 66.21 ± 3.87 yr, one male) were asked to continue their daily routine for 8 weeks. MAIN OUTCOME MEASURE: Hip muscles strength was measured using a multimodal dynamometer and ground reaction force using the backward stepping test and the results of the crossover stepping test were recorded using a force platform. RESULTS: The VR group showed significant improvement in hip muscle strength of the extensors, flexors, adductors, and abductors after 8 weeks (all p ≤ 0.001). However, no significant improvement was observed in the control group. The VR group had significantly greater ground reaction force on the backward stepping test (with eyes opened and closed) (all p < 0.005), and the crossover stepping test (with eyes opened and closed) (all p ≤ 0.001) compared to those at baseline. However, no significant improvement was observed in the control group. CONCLUSION: The VR-based exercise program includes the role of supervisor and feedback, which is important for the elderly. Therefore, a VR-based exercise program may be a useful tool to improve decreased physical function in the elderly as a home-based exercise.
