Pulsed diathermy is associated with which healing change?

• A. Increase phagocytosis
• B. Decrease white blood cell count
• C. Reduce collagen synthesis
• D. Increase scar tissue formation

Answer: (A)

Pulsed diathermy produces non-thermal effects that boost cellular activity involved in early healing. This energy can enhance phagocytic function of immune cells, such as macrophages and neutrophils, helping to clear debris and bacteria more efficiently. That accelerated cleanup supports the inflammatory and proliferative phases of healing, making increased phagocytosis the most consistent and beneficial change associated with this modality. Decreasing white blood cell count is not a typical effect of pulsed diathermy; the emphasis is on promoting immune cell activity. Reducing collagen synthesis would hinder tissue repair, and while later stages involve scar formation, the hallmark pulsed diathermy effect cited in many studies is improved phagocytosis rather than forcing more scar tissue.
