Which waveform configuration is used with high-voltage pulsed monophasic stimulation to minimize superficial tissue damage?

• A. Monophasic spike delivered in pairs
• B. Biphasic symmetric pulse
• C. Triphasic waveform
• D. Unipolar direct current

Answer: (A)

High-voltage pulsed monophasic stimulation aims to deliver a very brief, high-amplitude impulse while avoiding prolonged DC effects at the skin. Delivering monophasic spikes in pairs provides a near balance of charge over a short interval. The first spike delivers the therapeutic current, and the second closely follows to counter the charge buildup, reducing electrode polarization at the skin and limiting superficial tissue irritation and damage. This paired, short-duration approach lets the high-voltage pulse be effective for healing or modulation without the downsides of a single monophasic pulse or continuous direct current.
