PURPOSE: To determine the effect of augmented reality (AR)-based otago exercise on muscle strength, balance, and physical factors in falls of elderly women. SUBJECTS AND METHODS: Thirty subjects were randomly assigned to AR group (AR, n = 10), yoga group (yoga, n = 10), and self-exercise group (self, n = 10). For 12 weeks, these groups were given lessons related to AR-based otago exercise including strengthening, balance training, or yoga three times a week (60 minutes each time) and self-exercise using elastic band exercise program. RESULTS: Knee flexion and ankle dorsiflexion strength were significantly improved in all three groups (AR, yoga, and self-exercise groups). Regarding balance, eye open center of pressure-x (EO CoP-x) was significantly decreased in AR group and yoga group. However, eye close CoP-x, eye open standard deviation-x (EO SD-x), and eye open height of ellipse (EO HoE) were only significantly decreased in AR group. AR group also showed meaningfully improved results in morse fall scale. CONCLUSION: Augmented reality-based otago exercise can improve muscle strength, balance, and physical factors in elderly women to prevent falls.
