Which characteristic defines high-voltage electrical stimulation?

• A. Output of 100 to 500 V.
• B. Output of 1 to 5 V.
• C. Output of 50 to 100 V.
• D. Output of 600 to 900 V.

Answer: (A)

High-voltage electrical stimulation is defined by its higher peak voltages, typically delivered as short pulses in the range of about 100 to 500 V. This higher voltage allows current to reach deeper tissues with a relatively small overall current, which is useful for modalities aimed at edema control, pain modulation, and tissue healing. That’s why the characteristic described—output in the 100 to 500 V range—best defines high-voltage stimulation. The other ranges fall outside this common HVES definition: 1 to 5 V is too low to be considered high-voltage; 50 to 100 V is below the typical HVES threshold; and 600 to 900 V exceeds the usual clinical HVES parameters.
