Abstract

Purpose

Previous research has found hemispheric asymmetries in the utilization of proprioceptive information. It is undetermined, however, if there is any change in asymmetry in proprioceptive function when external stimulation, such as vibration, is presented. The present study was to investigate the immediate effects of vibration stimulation (VS) on bilateral ankle proprioception.

Materials and methods

Forty-six recreational male basketball players were included. Proprioception was assessed by using the active movement extent discrimination apparatus (AMEDA) in standing, and vibration was provided by using a vibrating form roller on the peroneal or gastrocnemius muscles.

Results

When participants were divided into high score and low score groups, according to the median of the baseline proprioceptive performance, VS (irrespective of whether vibrating the peroneal or gastrocnemius muscles) significantly improved left non-dominant ankle proprioception in the low proprioceptive performer group (p = 0.019), while significantly deteriorated right dominant ankle proprioception in the high proprioceptive performer group (p = 0.011).

Conclusions

The results found that external stimuli reversely affect proprioception in better and worse performing groups. This suggests that there are differences in the processing of external stimulus signals on different bilateral hemispheres and in different groups (high score vs low score groups), which may be related to hemispheric asymmetry and stochastic resonance. Therefore, it is necessary to explore more specific interventions in the future.

小腿肌肉的振动对高、低本体感觉表演者组的左右脚踝本体感觉有相反的影响

摘要

目的

先前的研究发现半球在利用本体感受信息方面存在不对称性。然而，当存在外部刺激（例如振动）时，本体感受功能的不对称性是否会发生任何变化尚不确定。本研究旨在研究振动刺激 (VS) 对双侧踝关节本体感觉的直接影响。

材料和方法

包括四十六名休闲男篮球运动员。本体感觉通过站立时使用主动运动程度辨别仪（AMEDA）进行评估，振动通过使用腓肠肌或腓肠肌上的振动滚轮提供。

结果

当参与者被分为高分组和低分组时，根据基线本体感觉表现的中位数，VS（无论是振动腓肠肌还是腓肠肌）显着改善了低本体感觉表演者组的左侧非优势脚踝本体感觉（p  = 0.019)，而在高本体感觉表演者组中，右优势踝本体感觉显着恶化 ( p  = 0.011)。

结论

结果发现，在表现较好和较差的群体中，外部刺激会反向影响本体感觉。这表明不同双侧半球和不同组（高分组 vs 低分组）对外界刺激信号的处理存在差异，这可能与半球不对称和随机共振有关。因此，有必要在未来探索更具体的干预措施。
