Although whole-body vibration (WBV) training is acknowledged for its benefits in enhancing motor functions across several neurological disorders, its precise influence on ankle joint proprioception and balance in stroke patients is still not well understood. This research seeks to assess the impact of WBV training on ankle joint proprioception and balance in stroke patients, thereby filling this important research void.
In this prospective cohort study, thirty-five stroke patients were randomly assigned to either the WBV group (n = 17) or a control group (n = 18) using a random number table method. The control group received daily general rehabilitation for four weeks, while the WBV group received an additional 30 min of WBV training each day with the Trunsan S110 Vibration Training System. Blinded outcome assessments were conducted at baseline and post-treatment, utilizing the Berg balance scale (BBS), Functional reach test (FRT), Romberg test length (RTL) and area (RTA), and completion rates of ankle joint dorsiflexion-plantar flexion (DP) and inversion-eversion (IE) tests. Follow-up assessments were performed after four weeks of intervention, focusing on RTL, RTA, DP, and IE as primary outcomes.
Analysis of intra-group changes from baseline to post-treatment revealed significant improvements across the BBS, FRT, RTL, RTA, and DP and IE assessments (p < 0.001). Notably, the WBV group showed significant enhancements compared to the control group in DP and IE (p < 0.001 and p < 0.05, respectively), with mean values increasing from 13.556 to 16.765 (23.7%) and from 5.944 to 8.118 (36.6%), respectively. However, WBV did not provide additional benefits over the control treatment for balance recovery parameters such as BBS, FRT, RTL, and RTA (p > 0.05).
This study demonstrates that WBV therapy is equally effective as conventional methods in enhancing proprioception and balance in stroke patients, but it does not provide additional benefits for balance recovery. WBV significantly improves proprioceptive functions, particularly in DP and IE parameters. However, it does not surpass traditional rehabilitation methods in terms of balance recovery. These findings indicate that WBV should be incorporated into stroke rehabilitation primarily to enhance proprioception rather than to optimize balance recovery.

尽管全身振动（WBV）训练因其在改善多种神经系统疾病的运动功能方面的益处而得到认可，但其对中风患者踝关节本体感觉和平衡的精确影响仍未得到充分理解。本研究旨在评估WBV训练对中风患者踝关节本体感觉和平衡的影响，从而填补这一重要的研究空白。
在这项前瞻性队列研究中，使用随机数字表法将35名中风患者随机分为WBV组（n = 17）或对照组（n = 18）。对照组接受为期四周的每日常规康复治疗，而WBV组每天使用Trunsan S110振动训练系统额外进行30分钟的WBV训练。在基线和治疗后进行盲法结局评估时采用伯格平衡量表（BBS）、功能性伸展测试（FRT）、罗姆伯格测试长度（RTL）和面积（RTA），以及踝关节背屈-跖屈（DP）和内翻-外翻（IE）测试的完成率等指标。在干预四周后进行随访评估时，将RTL、RTA、DP和IE作为主要结局指标加以重点关注测量。
对从基线到治疗后的组内变化分析显示BBS、FRT、RTL、RTA以及DP和IE评估均有显著改善（p < 0.001）显著提升。值得注意的是，WBV组在DP和IE方面与对照组相比有显著改善（分别为p < = 0.001和p < = 0.05），均值分别从13.556增加到16.765（增长23.7%）和从5.944增加到8.118（增长36.6%）。然而，对于BBS、FRT、RTL和RTA等平衡恢复参数，WBV并未比对照治疗提供额外益处（p > 0.05）。
本研究表明，WBV疗法在增强中风患者本体感觉和平衡方面与传统方法同样有效，但在平衡恢复方面并未提供额外益处。WBV能显著改善本体感觉功能，尤其是在DP和IE参数方面。然而，在平衡恢复方面它并未超过传统康复方法。这些发现表明，WBV应主要纳入中风康复以增强本体感觉，而非优化平衡恢复。
本研究于2024年7月29日在国际标准随机对照试验编号注册库（ISRCTN Registry）进行回顾性注册（https://www.isrctn.com/，ISRCTN64602845）。
