What is thermotherapy?

• A. Cold application to the body
• B. Application of heat to the body
• C. Electrical stimulation
• D. Ultrasound therapy

Answer: (B)

Thermotherapy is the therapeutic use of heat applied to the body to raise tissue temperature. This increased heat promotes effects like improved blood flow, reduced muscle stiffness, decreased pain, and enhanced tissue extensibility, which can facilitate healing and stretching.

That’s why the best answer is the description of applying heat to the body. Cold application is cryotherapy, not thermotherapy. Electrical stimulation and ultrasound therapy are distinct modalities; while ultrasound can generate heat, its primary purpose is not defined as thermotherapy.
