In relation to injury response, diathermy is described as providing which effect?

• A. Penetrate deeper
• B. Comfortably warm
• C. Heats superficially
• D. Causes tissue cooling

Answer: (A)

Diathermy’s defining feature is heating that reaches deep into tissues. It uses high-frequency electromagnetic energy to raise temperatures in deeper structures like muscle and connective tissue, not just the skin. This deep heating helps improve blood flow and metabolism, increases tissue extensibility, and can reduce stiffness and pain in rehab. It’s different from superficial heating (which mainly warms the surface) and from cooling modalities (which reduce temperature). So the best description is that diathermy penetrates deeper.
