Enhancement process of Kinesthetic Illusion caused by vibrational stimuli

Abstract

The kinesthetic illusion (KI) is described as flowing: when a suitable vibration stimulus is applied to tendons or muscles, the stimulus tends to feel as if the stimulated tendons or muscles were stretched and related limbs were moving. It is expected that rehabilitation will be promoted by the occurrence of movement image. In this study, we are attempting to investigate enhancement process of the movement image induced in a brain of a human subject experienced KI for the first time while performing the number of experiments. For the abovementioned investigation, we performed a series of five experiments applying a vibration stimulus to the tendon of right flexor carpi radialis muscle (FCR) of each human subject using a desktop device inducing KI equipped with a voice coil motor to evaluate sensation of KI with magnitude estimation. As a result, it was found that the intensity of KI occurrence was increased with implement number of the five experiments.
