Abstract
A massage device which utilizes the combination of electroneurological stimulation and mechanical massage for medical treatment of pain. The apparatus includes a housing having a massage head formed from a plurality of elongate rollers, connected to the electrical output of a pulse-generating circuit. The rollers form a mechanical massaging head, while the electrical pulses stimulate underlying nerves to block or reduce pain. A second or ground electrode is provided by an expansion band which can be easily slipped on an ankle or wrist and is connected to the main electrical circuit by a flexible electrical cord. The pulse-generating circuit includes a pair of switches for selecting a discrete voltage amplitude over a varying predetermined range, and a light-emitting diode to indicate operation of the pulse-generating circuit. Also included in the case or housing is a ball electrode for massaging and treating particular body points known as acupuncture or trigger points. The ball electrode is in the form of a roller ball installed in a ball socket in the housing, and is also connected to the output of the pulse-generating circuit.
