What must be present in the drum diathermy configuration to manage moisture?

• A. Towels to soak up moisture
• B. Water bath
• C. Plastic wrap
• D. Fan

Answer: (A)

Moisture control in drum diathermy is essential because excess moisture can change electrical impedance, leading to uneven heating or safety risks. Towels placed inside the drum soak up sweat and condensation, keeping the environment drier and more predictable. This helps maintain good contact between the heating surface and the body, improves heat transfer, and reduces the chance of hotspots or skin irritation. A water bath would add moisture rather than control it; plastic wrap could trap condensation and interfere with heat transfer; a fan dries air but doesn’t actively regulate moisture inside the drum.
