BACKGROUND
This systematic review was performed to summarize the current evidence for whole body vibration (WBV) interventions on postural control in elderly.
METHODS
English and German language papers in Medline, PEDro, Cinahl and the Cochrane databases were searched. Two reviewers extracted data on patients' characteristics, type of WBV intervention and outcomes. Two independent reviewers rated the methodological quality of these studies. Data were pooled using random-effects meta-analysis.
RESULTS
Fifteen papers reporting quantitative data were included. Results from 15 papers could be pooled for a meta-analysis. The studies involved 933 participants. In 7 studies the authors investigated the effects of vibration plates generating vertical sinusoidal vibrations (VS-WBV) and 7 papers described the use of side-alternating sinusoidal vibrations (SS-WBV). One study investigated both VS-WBV and SS-WBV.Weak to moderate evidence of an overall effect as a result of VS-WBV and SS-WBV was observed for (a) static balance for post-intervention values with a standardized mean difference (SMD) -0.06, 95% CI -0.31 to 0.18 and for change values SMD -0.26, 95% CI -1.09 to 0.57, and (b) dynamic balance for post-intervention-values SMD -0.34, 95% CI -0.60 to -0.08. For functional balance (c) an overall outcome for post-intervention values with SMD of 0.34, 95% CI -0.19 to 0.87 was found.
CONCLUSIONS
The 15 studies reviewed were of moderate methodological quality. In summary, SS-WBV seems to have a beneficial effect on dynamic balance in elderly individuals. However, the current results should be interpreted with caution because of the observed heterogeneity of training parameters and statistical methods. Future studies are warranted to evaluate the effects of WBV on postural control in an elderly population.
背景
本系统评价旨在总结目前关于全身振动（WBV）干预对老年人姿势控制的证据。
方法
检索 Medline、PEDro、Cinahl 和 Cochrane 数据库中的英文和德文文献。两名评审员提取患者特征、WBV 干预类型和结局的数据。两名独立评审员对这些研究的方法学质量进行评分。使用随机效应荟萃分析汇总数据。
结果
纳入了 15 篇报告定量数据的文献。15 篇文献的结果可进行荟萃分析。这些研究共纳入 933 名参与者。在 7 项研究中，作者研究了产生垂直正弦振动（VS-WBV）的振动板的效果，7 篇论文描述了侧向交替正弦振动（SS-WBV）的使用。一项研究同时研究了 VS-WBV 和 SS-WBV。由于 VS-WBV 和 SS-WBV，静态平衡的（a）干预后即刻值和（b）变化值的整体效果有弱至中度证据，标准化均数差（SMD）分别为-0.06（95%CI：-0.31 至 0.18）和-0.26（95%CI：-1.09 至 0.57），动态平衡的（a）干预后即刻值和（b）变化值的整体效果有弱至中度证据，SMD 分别为-0.34（95%CI：-0.60 至 -0.08）。对于功能性平衡（c），干预后即刻值的整体结局为 SMD 为 0.34（95%CI：-0.19 至 0.87）。
结论
综述的 15 项研究具有中等的方法学质量。总的来说，SS-WBV 似乎对老年人的动态平衡有有益的影响。然而，由于训练参数和统计方法的异质性，当前的结果应谨慎解释。需要进一步的研究来评估 WBV 对老年人群体姿势控制的影响。
