Match the diathermy method with its correct description: Induction method; Capacitive method; Drum method; Cable method.

• A. Induction method: Place body part into electromagnetic field
• B. Capacitive method: Wrap around body part
• C. Drum method: Two plate electrodes on each side of body
• D. Cable method: Towels to soak up moisture

Answer: (A)

Induction diathermy heats tissue by generating an electromagnetic field that surrounds the body part; this field induces eddy currents inside the tissues, and the tissue’s resistance converts that energy into heat. The description that matches this method is placing the body part into an electromagnetic field, because that directly describes how induction diathermy delivers energy: by exposing the part to the oscillating magnetic field produced by the applicator. The capacitive method, in contrast, uses two conductive plates on opposite sides of the body, creating an electric field and heating tissues between the plates; the idea of “wrap around” the body part isn’t the standard depiction of this method. The drum method involves a drum-like chamber or configuration with electrodes around the body, not simply two plates on each side. The cable method description about towels soaking up moisture doesn’t align with the typical modality descriptions.
