Which configuration describes the cable method in diathermy?

• A. Wrap around the body part
• B. Two plate electrodes on each side
• C. Towels to soak up moisture
• D. Heat dissipation is faster than ultrasound

Answer: (A)

In diathermy, the cable (capacitive) method heats tissue by forming a capacitor with the body. Wrapping an insulated electrode around the body part creates that capacitive field around the circumference, so current flows through the tissues beneath the wrap and heat is generated inside rather than only at a single surface. This wrap-around configuration is the defining feature of the cable method, ensuring energy reaches deeper tissues by surrounding the area of treatment. Other setups describe different approaches or properties (such as flat plates on opposite sides or moisture considerations), but they don’t depict the wrap-around capacitive arrangement.
