What are the two induction configurations used in diathermy?

• A. Drum and Cable
• B. Coil and Plate
• C. Pad and Probe
• D. Box and Wire

Answer: (A)

In diathermy, energy is delivered to tissues in two main ways: inductive heating and capacitive heating. The inductive method uses a coil placed near the treatment area. As the current in the coil alternates, a changing magnetic field is produced, which induces currents within deeper tissues. Those induced currents generate heat inside the tissues, especially targeting deeper structures with less superficial heating. The capacitive method uses two plates placed on opposite sides of the body part. The space between the plates acts as a dielectric, and an electric field drives energy through the tissues. Dielectric heating occurs as the tissues with higher water content or specific dielectric properties absorb energy, which often results in more superficial heating but can reach deeper tissues depending on tissue properties and settings. These two configurations—coil (inductive) and plate (capacitive)—are the standard ways diathermy energy is delivered. Coil is typically favored for deeper, larger areas, whereas plates are used for more superficial heating or when plate placement is advantageous.
