Abstract: | The present paper introduces an original biofeedback system for improving human balance control, whose underlying principle
consists in providing additional sensory information related to foot sole pressure distribution to the user through a tongue-placed
tactile output device. To assess the effect of this biofeedback system on postural control during quiet standing, ten young
healthy adults were asked to stand as immobile as possible with their eyes closed in two conditions of No-biofeedback and
Biofeedback. Centre of foot pressure (CoP) displacements were recorded using a force platform. Results showed reduced CoP
displacements in the Biofeedback relative to the No-biofeedback condition. The present findings evidenced the ability of the
central nervous system to efficiently integrate an artificial plantar-based, tongue-placed tactile biofeedback for controlling
control posture during quiet standing. |
