Abstract: A deep muscle stimulation device having a titanium hollow head with loosely packed granular materials held therein is reciprocally mounted in a hollow top and driven by a rotating electrical motor held in a hollow handle so as to provide deep muscle tissue with kinetic forms of percussion and concussion vibration so as to benefit damaged muscles in a patient. The hollow head is connected by a number of reciprocating elements to a finger on a rotating cam so as to have between a ⅛ to ½ inch stroke at a high rate of speed to provide deep penetrating muscle tissue stimulation. The device is easy to handle, and includes an on/off switch and an electrical cable-coupling element. The device is made from high strength materials, such as stainless steel or titanium, so as to hold up under heavy use by professionals in a number of disciplines.
