Effects of visual biofeedback training for fall prevention in the elderly

[Purpose] The purpose of this study was to investigate the effects of six weeks of visual biofeedback training for prevention of falling in the elderly. The Tetrax system was used for visual biofeedback training. [Subjects and Methods] Thirty elderly persons (experimental group=15, control group=15) who were above 70 and under 80 years of age participated in biofeedback training. They were trained for 15 minutes a day, three times per week. We measured the weight distribution index, stability index, and fall index in the subjects using the Tetrax system, and paired t-tests were used to evaluate the changes before and after intervention. The difference between the groups was compared using an independent t-test. [Results] The experimental group showed significant differences in weight distribution index, stability index, and fall index. The control group showed no significant differences. According to the comparison of training effects between the two groups, the variables of stability index and fall index revealed a statistically significant difference. [Conclusion] The method of visual biofeedback training used in this study should be considered a therapeutic method for the elderly to improve weight distribution, stability, and effectiveness in preventing falls.
