Which modality causes a tissue temperature rise in deeper tissues?

• A. Deep thermotherapy
• B. Cryotherapy
• C. Cryostretch
• D. Radiation

Answer: (A)

Understanding how heat moves into body tissues helps explain which modality can raise temperature in deeper structures. Deep heating modalities are designed to penetrate beyond the skin and warm deeper tissues like muscle and joint tissues, improving blood flow, tissue extensibility, and metabolic activity. Deep thermotherapy is the modality that specifically aims to elevate tissue temperature, including deeper tissues. Cryotherapy lowers tissue temperature, while cryostretch combines cooling with stretching, so they do not promote deep heating. Radiation tends to heat more superficially in typical rehab contexts. Therefore, deep thermotherapy best explains a rise in temperature in deeper tissues.
