Pulsed diathermy healing is associated with an increase in which process?

Pulsed diathermy healing is associated with an increase in which process?

• A. Increase phagocytosis
• B. Increase white blood cells
• C. Increase collagen bundles
• D. Increase capillary dilation

Answer: (A)

Pulsed diathermy’s non-thermal effects during healing are most closely tied to activating immune cells to clear debris. The intermittent energy can stimulate macrophages and neutrophils to perform phagocytosis more actively, helping remove damaged tissue and microorganisms at the injury site and speeding the transition from the inflammatory stage to repair. While heating can influence blood flow and collagen production, the specific action most directly enhanced by the pulsed, non-thermal modality is increased phagocytic activity.
