Nonthermal diathermy effects on inflammation include which cellular process?

• A. Charged ions migrate
• B. Increased edema
• C. Decreased blood flow
• D. Tissue dehydration

Answer: (A)

The effect being tested is how nonthermal diathermy interacts with cells to influence inflammation through electrical forces. Nonthermal diathermy uses an electromagnetic field that doesn’t heat tissue, but it does exert alternating electrical forces on charged particles. This causes charged ions to migrate and move across cell membranes, which can alter membrane permeability and intracellular signaling. That ion movement helps modulate inflammatory cell activity and mediator release without a temperature rise. Edema, reduced blood flow, or tissue dehydration aren’t the primary cellular changes produced by nonthermal electromagnetic fields. Edema involves fluid dynamics and swelling, decreased blood flow would counter microcirculation benefits, and dehydration relates to fluid loss—none of which are the targeted ion-movement effects seen with nonthermal diathermy.
