Which statement correctly describes the drum method?

• A. Requires towels to absorb moisture
• B. Uses two plate electrodes on each side
• C. Has space between cables
• D. Involves wrapping around a body part

Answer: (A)

The drum method relies on controlled delivery of energy to tissues inside a cylindrical enclosure, and managing the skin–interface is key for safe, even heating. Towels are used to absorb moisture at the skin because sweat or dampness can change the tissue impedance and create uneven heating or burns. Keeping the surface dry helps maintain a stable impedance and directs the energy into deeper tissues rather than spreading unpredictably along a wet surface. The other options describe different setups (such as capacitive plate configurations, spacing of cables, or wrapping around a body part) that aren’t characteristic of the drum method.
