Heat therapy

Muscle relaxation and circulation support with superficial heating such as hot packs and paraffin.

A physical therapy application that reduces pain, muscle spasm, and joint stiffness by warming superficial tissues with methods such as hot water bottles, hot packs, and paraffin baths (especially for hands and feet).

Indication

  • Chronic muscle spasm and tension in the neck and lower back
  • Management of morning stiffness in rheumatoid arthritis and osteoarthritis (outside acute flare-ups)
  • Support in myofascial pain syndrome and trigger point treatment
  • Conditions involving small joints of the hands and feet (paraffin bath)
  • At the start of physical therapy programs for chronic musculoskeletal pain
  • Soft tissue warming and flexibility enhancement before exercise

Preparation

  • The skin in the treatment area should be intact and evaluated for sensory loss
  • Open wounds, acute inflammation, bleeding, or fresh bruises should be reported to the physician
  • Careful application is required in patients with circulation problems, diabetes, and sensory loss
  • Jewelry and metal accessories are removed from the application area
  • Hands/feet are washed and thoroughly dried before paraffin bath

How it's performed

  1. Hot pack: the package taken from the special heater is wrapped with a towel and applied to the skin
  2. Adequate insulation between skin and pack reduces the risk of burns
  3. Hot pack application time is generally 15-20 minutes
  4. Paraffin bath: the hand or foot is dipped several times in lukewarm paraffin to form layers
  5. It is covered with plastic and a towel and waited for 15-20 minutes, then removed
  6. If burning or excessive heat sensation occurs during application, the procedure is stopped immediately

Post-procedure

  • Mild redness in the area after treatment resolves within minutes
  • Stretching and mobility exercises after heat application are recommended
  • Skin color and sensation are checked; abnormal changes are reported to the physiotherapist
  • Programs of 10-15 sessions are generally applied, adjusted to the individual
  • Education on safe methods for similar applications at home may be provided

Risks

  • Heat application is not recommended in the first 48-72 hours of acute injuries; cold application is preferred
  • Skin burns; risk is increased especially in patients with sensory loss, diabetes, and circulation problems
  • Not applied in cases of open wounds, acute inflammation, deep vein thrombosis, and active bleeding
  • Tumor areas and sensitive skin areas constitute contraindications
  • Not sufficient on its own; planned together with exercise and posture corrections

FAQ

Should I apply heat or cold to a fresh injury?

Cold application is preferred in the first 48-72 hours after acute injury. During this period, heat application may increase swelling. Heat application is more useful in the chronic phase, for muscle spasm and stiffness.

How can I safely apply heat at home?

A towel should be placed between the skin and the heat source, application should not exceed 15-20 minutes, and application should not be done while sleeping. People with diabetes, circulation problems, or sensory loss should apply only with physician approval.

Who is a paraffin bath suitable for?

It is used to reduce pain and stiffness in chronic conditions affecting the small joints of the hands and feet, such as rheumatoid arthritis and osteoarthritis. It is not recommended in cases of skin infection, open wound, or allergy.

Is heat therapy enough on its own?

No. Heat therapy is a preparatory application that sets the stage for exercise and other physical therapy methods. Stretching, strengthening, and posture corrections are needed for lasting results.
