Which condition may thermotherapy help relieve?

• A. Myofascial trigger points
• B. Fracture
• C. Acute bleeding
• D. Open wound

Answer: (A)

Thermotherapy works by raising tissue temperature to increase blood flow, ease muscle stiffness, and reduce muscle spasm. This makes it particularly helpful for myofascial trigger points, which are tight, irritable bands within a muscle. Heat helps the muscle relax and can lessen the local sensitivity of those trigger points, often reducing both the focal pain and any referred pain.

In contrast, heat is not appropriate for a fracture, acute bleeding, or an open wound. Heating an area with a fracture can worsen swelling or bleeding and may interfere with healing. For acute bleeding, heat promotes vasodilation and can increase the amount of bleeding. And applying heat over an open wound risks infection and tissue damage. So the scenario where thermotherapy provides relief is for myofascial trigger points.
