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.
