摘要
Background： This preliminary study examined the effects of an 8-week supervised reactive balance training program on reaction time （RT） and foot speed, static balance and balance confidence in healthy older adults compared to an exercise control group. Methods： Twenty-five older adults were randomly assigned to a reactive balance training group （QuickBoard; n = 12; 71.0 ± 8.6 years） or a stationary cycling group （control; n = 13; 70.2 ± 6.0 years）. Both groups were tested for foot RT foot speed, static balance, and balance confidence at baseline, 4-week, 8-week, and 4-week follow-up. Results： Results indicated significant improvements in QuickBoard foot RT and speed in both groups with greater improvements in the QuickBoard group. However, no group difference was found in static balance performance. Conclusion： Although the improvements in RT and foot speed may be beneficial for fall and trip prevention, the implications of the current findings for trio avoidance and oerformance of daily tasks are unclear.
目的:评价8周指导性反应平衡训练对健康老年人反应时、足部移动速度、静态平衡以及平衡信心程度的作用。方法:25名老年受试者被随机分配至反应平衡训练组(QuickBoard;n=12;71.0±8.6岁)或固定足部自行车训练组(对照组;n=13;70.2±6.0岁)。两组均进行足部反应时、足部移动速度、静态平衡以及平衡信心程度测试。测试时间分别为训练前(基线)、4周训练后、8周训练后及完成训练4周以后随访。结果:两组足部反应时和移动速度均有显著改善,且QuickBoard组提高幅度更大。在静态平衡表现上两组无显著差异。结论:尽管改善反应时和足部移动速度有助于预防跌倒,但本研究对如何预防跌倒及提高日常生活质量的意义尚不明确。
