What is a reported benefit of diathermy?

• A. Provides topical anesthesia
• B. Measures tissue oxygenation
• C. Visualizes soft tissues
• D. Uses soundwaves to generate heat for therapeutic purposes

Answer: (D)

Diathermy works by delivering high‑frequency electromagnetic energy to tissues, which converts to heat inside the tissue. The therapeutic benefit comes from this deep heating: it raises tissue temperature, causing vasodilation, increased blood flow, improved tissue extensibility, and pain relief. Among the common statements about what diathermy accomplishes, heat generation for therapeutic warming best describes its effect. The other ideas listed—topical anesthesia, measuring tissue oxygenation, or visualizing soft tissues—aren’t typical outcomes of diathermy. (If you’ve seen a statement about using soundwaves to generate heat, that describes ultrasound therapy, not diathermy.)
