Which diathermy type is seldom used in the US due to contraindications?

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

Answer: (A)

Microwave diathermy is rarely used in the United States because its safety profile is more problematic than other heating modalities. It delivers energy at a high frequency, which can heat tissues very quickly and in a less predictable way. This makes it harder to control energy delivery and increases the risk of hotspots and skin burns if the treatment isn't perfectly applied or if the patient moves. In addition, microwaves can interact with metal objects and implanted devices (such as pacemakers or other electronic implants), potentially causing heating of the device or interference with its function. These contraindications, along with concerns about energy focusing and safety, lead clinicians to prefer other diathermy types (like shortwave or pulsed shortwave) that offer safer, more controllable heating. As a result, microwave diathermy has diminished use in US practice.
