摘要:

目的 构建一种能够开展足底皮肤振动刺激对人体姿势控制影响研究的实验测试系统,并验证其有效性。方法 设计制作能够实现振动刺激的机械装置和控制系统,应用生物力学测试方法,于2019年10月2日至6日,对25例健康大学师生开展足底振动刺激实验。选取每位受试者的左足前部、左足后部、右足前部、右足后部、左足、右足、双足前部、双足后部8个振动位置,分别在20 Hz、40 Hz、60 Hz和80 Hz频率下,施加振幅1 mm的振动刺激,对比不同振动条件下的姿势响应情况。结果 足底振动刺激下压力中心响应幅值比与非振动条件下响应幅值有显著性差异(P < 0.05)。结论 测试系统能够对足底不同位置施加不同频率、不同幅值的振动刺激,并且能够采集、分析不同振动条件下受试者压力中心的变化趋势。该系统可以用于足底无毛皮肤振动刺激对于人体姿势控制测试的临床实验研究。

Abstract:

Objective To construct a testing system for the effects of plantar surface vibration stimulation on the human postural adjustments, and to explore its practicability.Methods The mechanical device and control system providing vibration stimulation were designed and built. Twenty-five healthy teachers and students (aged 19~29 years) were recruited from our college to participate in the experimental study from 2nd to 6th, October, 2019. The amplitudes of postural response were compared following non-stimulation and stimulation at left forefoot, left heel, right forefoot, right heel, left foot, right foot, double forefoot, double heels of each subject at the 20 Hz, 40 Hz, 60 Hz and 80 Hz vibrations, respectively.Results The amplitude of the center of pressure response under foot cutaneous stimulation increased compared with the response amplitude under non-vibration conditions (P < 0.05).Conclusion The locations of vibration as well as different vibration parameters (such as frequency, amplitude) could be adjusted, and the information of postural response to vibratory stimulation of the plantar surface, especially the excursion of center of pressure could be collected in the system which can be applied in the experimental study on the human posture control.
