[Purpose] The purpose of this study was to determine the effects of augmented
reality-based Otago exercise on balance, gait, and falls efficacy of elderly women.
[Subjects] The subjects were 21 elderly women, who were randomly divided into two groups:
an augmented reality-based Otago exercise group of 10 subjects and an Otago exercise group
of 11 subjects. [Methods] All subjects were evaluated for balance (Berg Balance Scale,
BBS), gait parameters (velocity, cadence, step length, and stride length), and falls
efficacy. Within 12 weeks, Otago exercise for muscle strengthening and balance training
was conducted three times, for a period of 60 minutes each, and subjects in the
experimental group performed augmented reality-based Otago exercise. [Results] Following
intervention, the augmented reality-based Otago exercise group showed significant
increases in BBS, velocity, cadence, step length (right side), stride length (right side
and left side) and falls efficacy. [Conclusion] The results of this study suggest the
feasibility and suitability of this augmented reality-based Otago exercise for elderly
women.
[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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
