Effects of Different Noise-Enhanced Vibrotactile Stimulation on Postural Control in Upright Standing: A Preliminary Investigation

Abstract

Stochastic resonance (SR) has been regarded as improving functions of sensory and motor in human via noise input, and increasing feedback of somatosensory may improve ability of posture control in upright standing. To date, regardless of previous literature has reported its efficacy of improving postural control, whether optimal noise can be used remains largely unknown. Present studies examined whether there was effect on postural control in upright standing using two types of interference waves: white noise (WN) with sinusoid signal and Gaussian noise (GN) with sinusoid signal. The finding suggests a promising setup for its application to increase postural control in upright standing. This study is aimed to examine the different effect on postural control in upright standing using two types of interference waves.
