HVPS is commonly used as an electric/nerve stimulator for management of which conditions?

• A. Pain, edema, and muscle weakness
• B. Fractures
• C. Skin infections
• D. Nerve compression syndrome

Answer: (A)

HVPS delivers brief, high-amplitude, monophasic pulses that interact with damaged tissues to modulate pain, promote edema reduction, and stimulate muscle activity. For pain control, the pulses disrupt pain signal transmission and can activate the body’s own analgesic pathways, providing relief without relying on medications. For edema, the electrical field helps boost lymphatic and venous drainage, reducing swelling around an injured area. When muscles are weak, HVPS can induce contractions that help maintain muscle mass and improve motor recruitment, supporting progression to active strengthening.

These three effects—pain relief, edema control, and muscle activation—are the primary reasons HVPS is commonly used in rehabilitation. Fractures rely mainly on stabilization and bone healing; skin infections require infection control and wound care; nerve compression syndrome is typically addressed by unloading the nerve and addressing the compressive cause, with electrical stimulation playing a secondary or adjunct role rather than the main treatment.
