Definition Short Wave Diathermy (SWD) is a treatment that uses electromagnetic energy to produce deep heating in joints and soft tissues. This form of heat can be applied to deeper structures than other forms of heat treatment. 3
Introduction Diathermy is a therapeutic modality that is most commonly used for joint conditions such as rheumatoid arthritis and osteoarthritis. The term diathermy refers to the creation of heat using electrical pulses. In diathermy, a high-frequency electric current is delivered via shortwave, microwave, or ultrasound which is able to generate deep heat in body tissues. The heat can be used to improve circulation and/or to relieve pain. In addition, shortwave diathermy can be used in medicine for treating damaged tissues and relaxing muscles. 4
Preparation for SWD Before a diathermy session, you must remove: All metal jewelry Clothing that includes metal, such as zippers or buttons Accessories containing metal You may be given a gown to wear during the procedure. You also may be asked to wear goggles. 5
How it Works? Short wave diathermy is a distinguished form of diathermy (different than ultrasound and microwave) which involves sending high-frequency waves throughout the patient s body and into the affected tissues. The energy waves are sent from condenser plates located on either side of the tissue being treated. Typical short wave diathermy machines operate at a frequency of 27.33 MHz and have wave lengths of 11 meters. 7
How it Works? Similar to other methods for applying energy to the body, short wave diathermy can be applied in two distinct modes: continuous or pulsed. When continuous mode is used, the tissue being targeted becomes heated as the waves constantly convey energy to them. Pulsed mode is used when less heat is desired for the affected tissue. 8
Benefits of SWD Short-wave diathermy includes non-thermal benefits as well including: Acceleration of cell growth Enabling damaged cells to return to normal function Increase wound healing 9
Benefits of SWD Short-wave Diathermy can be effective in providing some relief and treatment of symptoms related to: arthritis back pain fibromyalgia muscle spasms myositis neuralgia sprains and strains tenosynovitis tendonitis 10
Risks of SWD The electromagnetic energy used in shortwave and microwave diathermy can cause extreme heat in metal devices such as: Bone pins Dental fillings Metal sutures This could cause burns in the tissue near the implant. The procedure should not be used over these areas to avoid the risk of burning. 11
Conclusion Shortwave diathermy has some benefits that should increase its consideration and use in physical therapy and rehabilitation. Used alone as a pain management modality or used in conjunction with other modalities in order to increase function, diathermy is an extremely effective tool in returning patients to pain-free function. From managing pain to facilitating wound healing, diathermy is able to address diverse problems that come up in rehabilitation and should be a tool to consider adding to treatment regimens. 12
