我们之前的研究表明，短时间的全身振动（WBV）不能显著改善养老院居民的跌倒风险，但观察到一些改善运动能力的趋势。目的本研究的目的是评估为期6个月的WBV训练对养老院居民功能和运动能力的影响。方法将患者随机分为两组：WBV组，每周进行3次训练，由5组15 s的30 Hz强度振动组成，为期6个月；对照组，日常生活正常。这种训练对跌倒风险的影响在6个月和12个月后通过蒂内蒂测试、“计时起来和走”测试和用三轴加速度计进行的10秒步行的定量评估进行了盲目评估。还观察到有瀑布发生。结果本研究纳入62名老年健康志愿者，其中女性47名，男性15名，平均年龄83.2±7.9岁。两组在Tinetti检验（p = 0.75）、Timed Up and Go检验（p = 0.19）和Locometrix (R)检验方面差异无统计学意义（p < 0.01），但双任务测量的步长除外。在12个月的研究中，没有观察到跌倒频率的显著组间差异。实验前6个月共记录跌倒42次：治疗组跌倒24次，对照组跌倒18次（p = 0.60）。6个月内共发生跌倒19例：治疗组跌倒8例，对照组跌倒11例（p = 0.52）。结论本研究未能确定在本研究使用的条件下，低剂量WBV对住院老年患者的功能和运动能力的有效性。然而，鉴于其他研究的积极结果，似乎有必要进行进一步的研究，并修改治疗方案，以澄清白细胞在老年人中的作用。
Background We have previously shown that short sessions of whole body vibration (WBV) were not able to significantly improve fall risk among nursing home residents but some trends towards an improvement of motor capacity were observed.Objective The objective of the present study was to evaluate the impact of 6-month training by WBV on functional and motor abilities among nursing home residents observed over a 12-month period.Methods Patients were randomized into two groups: the WBV group which received three training sessions every week composed of five series of 15 s of vibration at 30 Hz intensity for a period of 6 months and a control group with normal daily life. The impact of this training on the risk of falls was assessed blindly after 6 and 12 months by the Tinetti Test, the ''Timed Up and Go'' test and a quantitative evaluation of a 10-s walk performed with a tri-axial accelerometer. The occurrence of falls was also observed.Results 62 elderly healthy volunteers, (47 women and 15 men, mean age 83.2 +/- 7.9 years) were included in this study. There was no significant difference between the two groups regarding the Tinetti test (p = 0.75), the ''Timed Up and Go'' test (p = 0.19) and the Locometrix (R) test, except for the step length, measured by dual task (p < 0.01). No significant inter-group difference in the frequency of falls was observed during the 12 months of research. A total of 42 falls were recorded during the first 6 months of experimentation: 24 falls in the treated group and 18 in the control group (p = 0.60). During the next 6 months, 19 falls occurred: 8 falls in the treated group and 11 in the control group (p = 0.52).Conclusion This study failed to establish the effectiveness of low doses of WBV, under the conditions used in our study, on functional and motor abilities of institutionalized elderly patients. However, given the positive results of other studies, further investigations, with modified therapeutic protocols, seem necessary to clarify the effects of WBV in the elderly.
