Which statement best describes thermotherapy in rehabilitation?

• A. Increases blood flow and promotes healing when applied at the appropriate time.
• B. Always reduces tissue metabolism.
• C. Exerts only analgesic effects with no impact on healing.
• D. Worsens muscle guarding unless combined with activity.

Answer: (A)

Thermotherapy raises tissue temperature, which triggers vasodilation and increased blood flow. This boost in circulation delivers more oxygen and nutrients to healing tissue and helps remove waste products, supporting the healing process when applied at the right time in the recovery timeline (typically after the acute inflammatory phase). Heat also increases tissue elasticity and can reduce muscle guarding by relaxing tight muscles, making it easier to perform therapeutic exercises. It does not always reduce metabolism; in fact, heat can raise local metabolic activity. It also provides more than just analgesia. For these reasons, thermotherapy best fits the idea that it increases blood flow and promotes healing when used at the appropriate stage of healing.
