Which HVPS parameter combination is described for wound healing?

• A. Negative polarity for edema
• B. Negative polarity for pain
• C. Rate 60-64 amplitude 100-150 V
• D. Rate 30-50

Answer: (C)

Wound healing with HVPC relies on delivering a brief, high-voltage, monophasic pulse to the wound bed, with the goal of stimulating cellular activity essential for repair—fibroblast proliferation, collagen synthesis, epithelialization, and improved blood flow. The effectiveness of this wound-healing effect depends on choosing an appropriate pulse rate and amplitude. A rate around 60–64 pulses per second (pps) provides a frequency that promotes tissue repair processes without causing irritation, while an amplitude in the 100–150 V range delivers enough energy to drive the biological responses while remaining comfortable for the patient. This specific combination aligns with standard wound-healing protocols using HVPC. Rates outside this range, such as 30–50 pps, are not the typical wound-healing settings, and selecting polarity for edema or pain targets different therapeutic goals rather than wound repair.
