Abstract

BACKGROUND

Whole-body vibration (WBV) is being used in rehabilitation and sport. Studies confirm its positive impact on muscle strength and power or regulating muscle hypertension. However, there are some uncertainties regarding its influence on postural stability. This issue seems particularly interesting in the case of individuals with generalized joint hypermobility (GJH), for whom proprioceptive training and muscle strengthening exercises are recommended while techniques that decrease muscle tension are not advised.

OBJECTIVE

The aim of the study was to evaluate the acute effect of WBV on postural stability in adults with GJH.

METHODS

60 participants were categorized into the groups: 1) hypermobility with vibration (GJH+WBV), 2) hypermobility without vibration (GJH-WBV), 3) control group with vibration (CTRL+WBV), 4) control group without vibration (CTRL-WBV). The first and the third group completed WBV (frequency: 15 Hz and 30 Hz, amplitude 3 mm, 3 × 3 min). The second and fourth groups participated only in measurement sessions. GJH was assessed using the Beighton test. Postural stability was measured as the overall stability index (OSI) on the Biodex Balance System on the stable and unstable platform with open and closed eyes. Measurements were taken before and after WBV for two weeks.

RESULTS

At a frequency of 15 Hz, a significant time effect was observed for measurements Before and After in CTRL-WBV on the stable platform with open eyes (p= 0.012) and on the unstable platform with closed eyes (p= 0.000) for the GJH+WBV and CTRL+WBV groups. There were no significant interactions (p> 0.05) between factors. At a frequency of 30 Hz, there was a significant time effect Before and After (p= 0.047) on the stable platform with open eyes, but no interaction was found between factors (p= 0.835).

CONCLUSION

There is no positive acute effect of WBV on postural stability in adults with and without GJH.

摘要

背景

全身振动（WBV）正被应用于康复和运动领域。研究证实其对肌肉力量和功率或调节肌肉高血压具有积极影响。然而，其对姿势稳定性的影响存在一些不确定性。对于患有广泛性关节过度活动症（GJH）的个体，这一问题似乎特别有趣，因为建议对其进行本体感觉训练和肌肉强化练习，而不建议使用降低肌肉张力的技术。

目的

本研究旨在评估 WBV 对 GJH 成人姿势稳定性的急性影响。

方法

60 名参与者被分为以下几组：1）振动性高可动组（GJH+WBV），2）无振动性高可动组（GJH-WBV），3）振动性对照组（CTRL+WBV），4）无振动性对照组（CTRL-WBV）。第一组和第三组完成 WBV（频率：15Hz 和 30Hz，振幅 3mm，3×3 分钟）。第二组和第四组仅参加测量。使用 Beighton 测试评估 GJH。使用 Biodex 平衡系统，在稳定和不稳定平台上，睁眼和闭眼时，通过整体稳定性指数（OSI）来测量姿势稳定性。在 WBV 前后两周进行测量。

结果

在 15Hz 频率下，CTRL-WBV 组在稳定平台睁眼时（p=0.012）和不稳定平台闭眼时（p=0.000），以及 GJH+WBV 和 CTRL+WBV 组，测量值 Before 和 After 存在显著的时间效应。两组之间没有显著的交互作用（p>0.05）。在 30Hz 频率下，稳定平台睁眼时，Before 和 After 存在显著的时间效应（p=0.047），但两组之间没有发现交互作用（p=0.835）。
