Abstract
Abstract An improved therapeutic vibration device using dual motors and rotating discs having eccentric weights. The rotating discs have slightly different effective diameters and are mutually frictionally connected by either providing the rims thereof with a different number of gear teeth or with an elastomeric or other friction material. A vibrational device having such separated motors can be enclosed in a cushion or pillow for convenient use by an individual.
