Background

Local vibration can improve balance problems of individuals with stroke when applied to the plantar region.

Aims

This study aimed to determine the immediate effect of local vibration applied to the plantar region on fall risk and postural stability in patients with stroke.

Study Design

Randomized controlled study.

Methods

30 patients (23 male,7 female) with stroke were randomized to either vibration (n = 15; 58.47 ± 8.23 years) or control (n = 15; 58.27 ± 9.50 years) groups. Before and after the intervention, the patients were evaluated using a Biodex Balance System. Local vibration was applied to the plantar region of two feet in the supine position using a vibration device for a total of 15 min to the individuals in the vibration group. While the patients in the placebo group were in the supine position, the device was brought into contact and no vibration was applied to the plantar region of two feet for 15 min.

Results

While significant improvements were observed in the postural stability and fall risk of the vibration group (p < 0.05), no significant change was observed in the placebo group (p > 0.05). Furthermore, significant improvements occurred in the SD values of the postural stability expressing postural oscillation in the vibration group (p < 0.05).

Conclusion

As a result of local vibration applied to the plantar region, immediate (within 5 min) significant improvements in postural stability and fall risk values were detected.

足底振动对中风患者跌倒风险和姿势稳定性的即时影响：随机对照试验

背景

当应用于足底区域时，局部振动可以改善中风个体的平衡问题。

目的

这项研究旨在确定施加于足底区域的局部振动对中风患者跌倒风险和姿势稳定性的即时影响。

学习规划

随机对照研究。

方法

30例中风患者（男23例，女7例）被随机分为振动组（n  = 15； 58.47±8.23岁）或对照组（n  = 15； 58.27±9.50岁）。干预前后，使用Biodex平衡系统对患者进行评估。使用振动装置对振动组中的个体在仰卧位置的两脚的足底区域施加局部振动共15分钟。安慰剂组的患者处于仰卧位置时，使该设备接触并且在15分钟内未对两英尺的足底区域施加振动。

结果

虽然观察到振动组的姿势稳定性和跌倒风险有显着改善（p  <0.05），但安慰剂组没有观察到显着变化（p  > 0.05）。此外，在振动组中，表示姿势振动的姿势稳定性的SD值发生了显着改善（p  <0.05）。

结论

由于局部振动施加于足底区域，因此立即（5分钟以内）检测到姿势稳定性和跌倒风险值的显着改善。
