Micro Therm / DiaPulse
This machine is not the same as a heating pad. Radio waves set at a certain frequency (such as in a radio) travel from the machine through the patient, back through the machine (a repeating cycle). As theses waves travel through the affected area, they stimulate tissue structures causing friction, and in turn produce heat.
Circulation is improved in the area being treated leading to a feeling of relaxation which aids in the reduction of mild muscle spasms.
