To investigate the efficacy of high-frequency whole-body vibration (WBV) on balancing ability in elderly women.
Randomized controlled trial. Subjects were randomized to either the WBV intervention or the no-treatment control group.
Community-living elderly women.
Sixty-nine elderly women aged 60 or above without habitual exercise.
Side alternating WBV at 20Hz with 3 minutes a day and 3 days a week for 3 months in the WBV intervention group. Those in control group remained sedentary with normal daily life for the whole study period.
Limits of stability in terms of reaction time, movement velocity, directional control, endpoint excursion, maximum excursion, and the functional reach test were performed at baseline and endpoint.
Significant enhancement of stability was detected in movement velocity (P<.01), maximum point excursion (P<.01), in directional control (P<.05).
WBV was effective in improving the balancing ability in elderly women. This also provides evidence to support our user-friendly WBV treatment protocol of 3 minutes a day for the elderly to maintain their balancing ability and reduce risks of fall.
探讨高频全身振动（WBV）对老年女性平衡能力的影响。
随机对照试验。受试者被随机分为WBV干预组或非治疗对照组。
社区居住的老年女性。
69名60岁及以上无习惯性运动的老年女性。
WBV干预组每天进行3分钟、每周3天、持续3个月的20Hz侧方交替WBV。对照组在整个研究期间保持久坐，日常生活正常。
在基线和终点时进行稳定性极限测试，包括反应时间、运动速度、方向控制、终点偏移、最大偏移和功能性伸展测试。
在运动速度（P<.01）、最大点偏移（P<.01）和方向控制（P<.05）方面检测到稳定性显著增强。
WBV对改善老年女性的平衡能力有效。这也为支持我们为老年人制定的每天3分钟的便捷WBV治疗方案提供了证据，该方案可维持其平衡能力并降低跌倒风险。
