Research Facts
A diathermy machine uses short wave radiation as the shource of heat. The therapeutic use of heat produced in tissues by electromagnetic radiation is called short wave diathermy (the best method applied to large areas) which causes a temperature rise from the conversion of energy into heat as it penetrates the tissues. The local effects occur due to the elevated local temperature which is associated with increased local blood flow, capiliary dilation and capillary permeability. It results on higher level tissue metabolism and more rapid transfer of nutritional ingredients to the end organs and tissues. It promotes faster healing. Short wave heat increases connective tissue elasticity, reduces muscle spasm and sedates the nerve endings to change the pain threshold. Conditions treated: arthritis, 'Blackberry Thumb', bunions, carpal tunnel syndrone, fibromyaligia, sprains, lower back pain, sciatica and stress fracture. Early non-shielded equipment emitted short waves that interferred with aircraft flying nearby and new equipment were approved by the Department of Transportation.
