Increased circulation

Increased circulation



Increased nerve conduction velocity

increased phagocytosis by activating macrophages

Activate growth factor in fibroblasts

Accelerate cell growth and division


Increased collagen extensibility



Clinical Indicators for Diathermy

Much like superficial heat, diathermy can be used effectively in conditions resulting from chronic spinal pain, sprains and strains, and postural dysfunctions. Pulsed diathermy can be used much like our non-thermal agents to control pain and edema. Most specifically, pulsed SWD is used to facilitate wound healing (post-surgical, decubitus ulcers, burn-related injury)
