Abstract: Massage apparatus for treatment of deep muscle in body tissue has a galvanic skin reactor having electrodes adapted to be attached to the skin combined with a massage device having massage elements with an amplitude of between 1/2 to 1" operating at a frequency of about 22 cycles per second, said galvanic reactor having response mechanism to indicate the change in resistance between the electrodes and enclosed skin caused by application of the massage elements.

Abstract: A massage device has a rocking member, a synchronous electric motor drive, an elastomeric pivot, a drive connecting member, a rigid structure supporting said pivot and massage elements on the rocking member which move in opposite direction during the rocking motion. Gripping means are secured to the rigid structure, at a location of minimum motion of the rigid structure to minimize the vibration transmitted to the operator; preferably the gripping means are resiliently secured to the rigid structure. The device is weighted so that the moment of force about the elastomeric pivot is sufficient to cause slowing of the motor when the massage members act on the body and increased pressure on the gripping means lowers the frequency of the massage elements. A weight, adjustable in position with respect to the elastomeric pivot, is located on the rigid structure in opposed relation to the drive connecting member; movement of the weight causes change in the amplitude of the massage elements.
