Abstract

Introduction. Balance decreases with age, and factors influencing balance can increase postural sway and displace the center of pressure. Reduced physical activity is a significant problem that contributes to impaired balance and an increased risk of falling in the elderly population. Routine exercise programs are often challenging in improving balance, whereas game-based activity can be more engaging and motivating for older adults. Game-based training using the Balance Postural Sway System (BPSS) was applied in this study to reduce postural sway and therapeutically improve balance.

Methods. This interventional study was conducted on 51 elderly adults who met the inclusion criteria. The intervention group (n = 26) underwent game-based activity with BPSS, while the control group (n = 25) received conventional balance training. The BPSS parameters used included the center of foot pressure X index (COFPXI) and Y index (COFPYI), which indicate the center of foot pressure with lateral sway and anterior-posterior sway, respectively. The left and right toe-heel values denote weight distribution between the toe and heel. The outcome measures used were the Fall Efficacy Scale International (FES-I) and the Berg Balance Scale (BBS).

Results. The paired t-test showed a significant difference in all BPSS parameters—COFPXI, COFPYI, right toe, BBS, and FES-I—except for the left toe-heel in the intervention group. In contrast, the conventional group showed a significant difference only in BPSS COFPYI, FES-I, and BBS (p < 0.05). The unpaired t-test demonstrated that the intervention group showed significantly greater improvements in all balance parameters of BPSS and FES-I (p < 0.05) than the conventional group, except for BBS.

Conclusion. Game-based activity with BPSS has been shown to reduce postural sway, improve pressure distribution on the foot, enhance balance, and decrease the risk of falls in the elderly population. The results suggest that incorporating such game-based activities into routine exercise programs for older adults can effectively improve balance and reduce fall risk.
