What effect does thermal diathermy have during the inflammatory response?

• A. Increase cellular metabolism
• B. Increase white blood cell count
• C. Increase capillary growth
• D. Increase fibroblast activity

Answer: (A)

Heating tissue with thermal diathermy raises the temperature inside the tissue, which speeds up the biochemical reactions that cells perform. That means cellular metabolism—how quickly cells produce energy, synthesize proteins, and carry out repair and defense processes—goes up. In the inflammatory response, this increased metabolic activity supports the actions of immune cells and the early steps of tissue repair by providing more energy and faster enzyme activity at the site. White blood cell counts are a systemic parameter and aren’t directly increased by applying heat to a local area. Capillary growth (angiogenesis) and fibroblast activity are more tied to longer-term healing and remodeling signals rather than the immediate effect of warming during inflammation. So the direct and best-described outcome of thermal diathermy in this context is an increase in cellular metabolism.
