Inflammation nonthermal diathermy mechanism involves which process?

• A. Charged ions migrate
• B. Cells migrate
• C. Temperature increases
• D. Pressure increases

Answer: (A)

Nonthermal diathermy relies on an alternating electromagnetic field to influence tissue, not by heating it. The oscillating field causes charged ions and dipolar molecules in the tissue to migrate or move, creating microcurrents at the cellular level. This ion movement can alter membrane potentials and cellular signaling, affect vascular permeability and lymphatic flow, and modulate inflammatory mediators, all of which help modulate inflammation without raising tissue temperature. That’s why charged ions migrating is the mechanism. The other options describe effects tied to heating or unrelated pressure changes, which aren’t how nonthermal diathermy produces its inflammatory effects.
