目的：研究全身振动加上运动计划对老年人功能活动能力和相关结果的影响。设计：单盲随机平行组试验。设置:英国;国家保健服务老年人评估和康复设施。参与者：体弱的老年人：38人（80 +/- 8.6岁）进行全身振动运动（振动组），39人（82 +/- 8.1岁）不进行运动（运动组）。干预：每周三次，每次60分钟，有监督的锻炼课，持续八周+/-全身振动（高达5 x 1分钟，15-30赫兹，峰对峰2-8毫米）。测量方法：在基线、4周（仅限活动能力测量）、8周和6个月时评估定时起床和行走、6米步行、静态平衡、摔倒恐惧（FES-I）和自我报告的健康状况（SF-12版本2）。结果：两组在8周时，Timed Up and Go和6米步行均有改善（P < 0.01），但振动组明显改善（Timed Up and Go: 38% vs. 20%, P < 0.05）；6米步行：（36比18.1%,P < 0.05）。两组的平衡、害怕跌倒和自我报告健康状况的身体成分改善相似（P < 0.05）。在随访中，任何测量都与基线没有显著差异。经历的平均总时间是最大目标的37%。结论：在力量和平衡运动中增加全身振动比单独运动更能改善功能活动，尽管其暴露程度低于预期。两种干预措施的收益都维持了6个月。
Objectives: To investigate the effects of whole-body vibration in addition to an exercise programme on functional mobility and related outcomes for frail older fallers.Design: Single-blind randomized parallel group trial.Setting: UK; National Health Service assessment and rehabilitation facility for older people.Participants: Frail older fallers: 38 (80 +/- 8.6 years) performed the exercise with whole-body vibration (vibration group), and 39 (82 +/- 8.1 years) without (exercise group). Intervention: Sixty minutes supervised exercise class three times weekly for eight weeks +/- whole-body vibration (up to 5 x 1 minute, 15-30 Hz and 2-8 mm peak-to-peak).Measurements: Timed Up and Go, 6-m walk, static balance, fear of falling (FES-I) and self-reported health status (SF-12 version 2) were assessed at baseline, four weeks (mobility measures only), eight weeks and six months.Results: Timed Up and Go and 6-m walk improved in both groups at eight weeks (P < 0.01), but significantly more in the vibration group (timed up and go: 38 vs. 20%, P < 0.05); 6-m walk: (36 vs. 18.1%, P < 0.05, respectively). Balance, fear of falling and physical component of the self-reported health status improved similarly in both groups (P < 0.05). At follow-up, no significant differences from baseline remained for any measure. The mean total time experienced was 37% of maximal target.Conclusion: The addition of whole-body vibration to strength and balance exercise resulted in greater improvements in functional mobility than exercise alone, despite achieving lower than anticipated exposure. Gains from neither intervention were sustained at six months.
