What is “DIATHERMY” ?The term diathermy  means “electrically

induced heat”, it is nothing but the use of high-frequency electromagnetic current as in a form of physical or occupational therapy and in surgical procedures.BENEFITS:

A benefit of “Diathermy” is that it is a painless procedure that can be administered at a clinic. Also, if the treatment relieves pain, so that patients can discontinue pain killers and escape their high cost and side effects.

SIDE EFFECTS:Some patients may experience superficial burns. Since the therapy involves creating heat, care must be taken to avoid burns, particularly in patients whose injuries have caused decreased sensitivity to heat. Also, diathermy may affect pacemaker function. APPLICATIONS:

To treat sports injuries To treat rigid joints and joint pain often

associated with arthritis .To heal these problems by increasing blood flow

to the injured area, controlling swelling and softening joint tissue.
