The Vibratory Chair
Another form of apparatus is the vibratory chair. This is a motor-driven arrangement, with an ordinary chair attached to the platform and the mechanism. It is provided with hand- holds, special attachments for the feet, an individual head- rest, and additional arrangements for grasping with the hands for vibration of the upper extremities. Hence one may, while seated in the chair, receive a vibratory treatment to the entire body, or one may so place oneself as to receive any local vibratory treatment. What lias been said earlier regarding the effects of vibration apply to that produced by this chair.
