Deep heat is another name for diathermy, as it provides heat beneath the skin in deeper sheets.

What is diathermy?

Diathermy is a very effective treatment for some diseases. Diathermy can boost heat production in specific areas, which results in increased blood circulation. It increases the flexibility of connective tissues. It reduces chronic inflammation, fluid retention, and edema. 


Diathermy can be divided into three categories depending on what type of energy is used

Short waves

To generate heat, it uses high-frequency electromagnetic radiation. It can be used to heat areas of the body that are covered in thick layers of soft tissue, such as your hips. It has many beneficial physiological effects.

  • Blood pressure falls
  • Increased metabolism
  • Increase blood supply
  • Reduce inflammation

It is used for treating

  • Degenerative joints
  • Strains and strains
  • Hematoma
  • Injuries to the tendon and muscle
  • Capsule inflammation

Microwave diathermy

It uses microwaves to treat, as its name implies. It is between infrared and short waves. It is more frequent but has a shorter penetration range than a short wave. It offers the same physiological benefits of short waves, but is closer to skin.

For treatment, the appropriate time is 20 minutes.

Ultrasound diathermy

Therapeutic ultrasound is another name for it. It generates heat by using sound waves. It is used to reduce inflammation and deliver drugs to targeted tissues.
