Abstract
Purpose: This study aimed to determine the most effective feedback condition for static balance in elderly subjects.
Methods: Thirty-eight elderly subjects (12 men and 26 women with a mean age of 77.21 years) participated in this study. They each completed a questionnaire on their general characteristics, excluding personal identification codes. The static balance ability of the participants was evaluated using a Wii Balance Board and the Balancia program (version 2.0). The following three feedback conditions were considered: condition 1 (tactile feedback), condition 2 (visual feedback), and condition 3 (no feedback). One-way repeated-measures analysis of variance was used for the comparisons according to sway length and sway velocity. The statistical significance level was set to α = .05 for all variables.
Results: Significant differences in the sway length and sway velocity were observed between the three conditions (p < .05). Significant differences in the sway length were noted in the order of conditions 1, 2, and 3 (p < .05), and significant differences in the sway velocity in the order of conditions 3, 2, and 1 (p < .05).
Conclusion: Significant differences in static balance ability were observed between the three conditions. In this study, tactile feedback was found to be the most effective feedback for balance training. Owing to aging and impairment of the senses, such as that observed in the tactile receptors, visual receptors, and proprioceptors, it is recommended that elderly subjects participate in balance training.
