Proprioception should be necessary for the trunk balance and skillful movement. However, proprioception deteriorates due to aging and low back pain. Mechanism of low back pain has not been elucidated clearly. The final aim of our research is to elucidate the mechanism of low back pain by developing a new vibration device. This paper presents a new variable vibration device to elucidate the mechanism of low back pain. In order to verify the availability of the new vibration device, the effect of vibratory stimuli with the frequency of 60 Hz on the body sway is investigated by eight healthy people. The results of the healthy people are as follows; (i)When paraspinal muscle is stimulated by vibration, the environmental area surrounding the locus of the center of gravity decreases, which means the body sway becomes better. (ii) In the case of gastrocnemius muscle, the environmental area increases, which means the body sway becomes worse. From these results the availability of the new vibration device was verified.
