Generation of shoulder internal and external rotation motion illusion with simultaneous stimulation of skin stretch and vibration

Abstract

It has been shown that two kinds of phenomenon called kinesthetic illusion and tonic vibration reflex (TVR) are induced by providing vibration stimulation to tendon of muscle. Here comes to a possibility that using kinesthetic illusion to generate sensation of movement and/or using TVR to achieve the movement. This research focuses on the generation of kinesthetic illusion of shoulder external rotation by stimulating infraspinatus. In order to increase the kinesthetic illusion effect, the study focuses on frequency of the vibration stimulation and simultaneous skin stretch. It has been shown that 80Hz generate the most effective kinesthetic illusion. Furthermore, the result shows that simultaneous skin stretch increases the amount of kinesthetic illusion.
