ABSTRACT:
A method for therapeutic deep heating of musculoskeletal tissues with an improved transducer that serves simultaneously to couple the power from the generator into the patient and to sense the therapeutic response for treatment control including a method of manufacture and testing of contact applicators for dielectric heating of musculoskeletal tissue. The applicator is comprised of rectangular wave guide in which dielectric material is placed to reduce the guide wave length to the free-space value at the frequency of operation. In addition, the invention comprises a method and apparatus for the noninvasive detection of therapeutic response in muscle tissue to dielectric heating. Ths response is then used to control the treatment. Both heating and sensing are accomplished by one transducer and one apparatus if dielectric heating is employed. If other forms of heating are used, such as ultrasound, the sensor still occurs but the apparatus must be modified, the modifications including replacement of the high power electromagnetic source with a low power source version.
