Longwave diathermy is the oldest method and is not used commonly anymore. Which option lists the other three diathermy modes?

• A. Shortwave, Microwave, Pulsed Shortwave
• B. Pulsed Shortwave, Microwave, Longwave
• C. Shortwave, Longwave, Pulsed Shortwave
• D. Microwave, Pulsed Shortwave, Longwave

Answer: (C)

Diathermy modalities are distinguished by their frequencies. Longwave is the oldest mode and stands apart from the others. The three modalities that are used apart from Longwave are Shortwave diathermy, Microwave diathermy, and Pulsed Shortwave diathermy. Shortwave diathermy uses a radiofrequency around 27.12 MHz and provides deeper heating; Microwave diathermy uses microwaves at about 2.45 GHz and tends to produce more localized, sometimes superficial heating; Pulsed Shortwave diathermy delivers the energy in bursts to control the rate of heating and improve comfort. So the correct trio is Shortwave, Microwave, and Pulsed Shortwave.
