A vibrating back massager with guide slot and vibrating heads is described. The guide slot is designed to restrict lateral movement of the massage device when the guide slot is engaged with a supporting member. The supporting member may be the edge of an open door, a corner, a vertical pole, or other generally available structure. The device includes a strap handle which may be draped over the user's shoulder and used to control the vertical position of the device. The described vibrating massage device allows a single user to create and maintain a significant amount of massage pressure without fatiguing his arms or relying on a second person. In a preferred embodiment, the controls for the vibrating massage device are incorporated into the strap handle so that the speed, intensity, and/or temperature may be controlled by the user without repositioning the device.
