Diathermy - Short Wave
Short Wave Diathermy uses high-frequency electrical currents to heat deep muscular tissues. The heat increases blood flow, speeding up recovery. The term diathermy is derived from the Greek words therma, meaning heat, and dia, meaning through. Diathermy literally means heating through.
Short Wave Diathermy, similar to your microwave oven, is best at heating tissues of high water content, like muscles. Because it can penetrate up to 4 inches under the surface of the skin, it is an excellent choice for heating the larger muscle groups such as the gluteal groups, the spinal erectors, the hamstrings, the quadriceps, etc.
Diathermy can be used to treat arthritis, bursitis, and other conditions involving stiff, painful joints. It is also used to treat pelvic infections and sinusitis. It is a painless procedure that can be administered at a clinic. Patients should be able reduce their dependence on pain killers.
Diathermy involves heating deep muscular tissues. When heat is applied to the painful area, cellular metabolism speeds up and blood flow increases. The increased metabolism and circulation accelerates tissue repair. The heat helps the tissues relax and stretch, thus alleviating stiffness. Heat also reduces nerve fiber sensitivity, increasing the patient's pain threshold.
