Deep Muscle Simulator (DMS) & Muscle Spasm

The Functional Movement Screen (FMS) has popularized our awareness of checking for asymmetries in the body during movement. Muscle strains and joint dysfunctions caused by asymmetrical movements over time can generally be reduced by treatment using the Deep Muscle Stimulator (DMS).

The DMS is a hand held device that delivers strong vibration, oscillation and percussion. Use of the DMS appears to reduce stiffness by signaling inhibition of the sympathetic nervous system. Palpate tight or stiff fascial tissue or a taut and tender muscle fiber, and then apply the Deep Muscle Stimulator (DMS) device for approximately two to three minutes, the post treatment/application will leave the skin red, warm and it will palpate as “softer.” This probably has to do with local changes in the arterioles and capilliaries and the mixing up of tissue viscosity.

To really appreciate the DMS, we need to review some neurology. Golgi receptors are located in dense connective tissues such as ligaments, joint capsules (Golgi end organs) and around myotendinous junctions (Golgi tendon organs).1 Golgi receptors are stimulated by slow active stretching or strong local pressure resulting in a lowered firing rate of associated alpha motor neurons via the spinal cord, this leads to decreased active muscle tone in related muscle fibers.
