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 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.
