What is diathermy?

Diathermy is a therapeutic treatment most commonly prescribed for muscle and joint conditions. It uses a high-frequency electric current to stimulate heat generation within body tissues.

The heat can help with various processes, including:

  • increasing blood flow
  • relieving pain
  • improving the mobility of tissues as they heal

Shortwave Diathermy 

Shortwave diathermy uses high-frequency electromagnetic energy to generate heat. It may be applied in pulsed or continuous energy waves. It has been used to treat pain from kidney stones, and pelvic inflammatory disease. It’s commonly used for conditions that cause pain and muscle spasms such as:

  • sprains
  • strains
  • bursitis
  • tenosynovitis

Diathermy uses high-frequency electric current to produce heat deep inside a targeted tissue. It can reach areas as deep as two inches beneath the skin’s surface.

The diathermy machine does not apply heat directly to the body. Instead, the waves generated by the machine allow the body to generate heat from within the targeted tissue.

Diathermy is usually part of a complete physical therapy or rehabilitative regimen. Frequency and length of treatments vary.

Treating injuries with heat can increase blood flow and make connective tissue more flexible. It can also help minimize inflammation and reduce the incidence of edema, or fluid retention.

By increasing blood flow to the site of an injury, the deep heat generated with diathermy can accelerate healing.

Diathermy is used to treat the following conditions:

  • arthritis
  • back pain
  • fibromyalgia
  • muscle spasms
  • myositis
  • neuralgia
  • sprains and strains
  • tenosynovitis
  • tendinitis
  • bursitis

People with implanted metal devices may be at risk for injury if they undergo any type of diathermy. These devices include:

  • pacemaker
  • prosthesis
  • intrauterine device (IUD)

You may not be an appropriate candidate for this treatment if you have:

  • cancer
  • reduced skin sensation
  • peripheral vascular disease
  • tissue with restricted blood supply (ischemia)
  • infections
  • fractured or broken bones
  • bleeding disorders
  • severe heart, liver, or kidney conditions
  • low skin sensation
  • pregnancy
  • perspiration
  • wound dressings

Diathermy is not considered safe for certain areas of the body. These include:

  • eyes
  • brain
  • ears
  • spinal cord
  • heart
  • reproductive organs
  • genitalia

Continuous shortwave diathermy is the technique of choice when uniform marked elevation of temperature is required in the deep tissues. This heating can be targeted accurately by using an appropriate applicator positioned correctly. SWD also allows superficial structures to be heated selectively, although for this the various methods of surface heating are usually preferable. Sub-acute or chronic conditions respond best to continuous shortwave diathermy which, when used properly, can be as effective as ultrasound. Acute lesions are better treated with pulsed shortwave diathermy. Continuous shortwave diathermy can help to relieve pain and muscle spasm, resolve inflammatory states and reduce swelling, promote vasodilation, increase the compliance of connective tissue, increase joint range and decrease joint stiffness.


What is Short-Wave Diathermy?

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.

The electric pulse of Short-Wave Diathermy creates heat deep inside a targeted tissue, reaching areas as deep as two inches from the skin’s surface. While the diathermy machine doesn’t apply heat directly to the body, the current created by the machine allows the body to generate heat within the targeted area itself.

It is when the heat of the area increases, that blood flow is improved along with improvements to flexibility in stiff joints and connective tissue making it a good choice to use for patients with arthritis.

The main benefits for decreased pain and inflammation is it allows patients to gently increase their range of motion allowing them to move with more ease and participate in rehabilitation with more comfort.


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. When short wave diathermy is applied in pulse mode, the mechanical effects of the treatment are applied independent of the thermally affecting (heating) the tissue. One of the most promising applications of pulsed mode is it is able to facilitate increased flexibility and joint mobilization for restoration of joint range of motion. 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
