What voltage range is used by high-voltage electrical stimulation?

• A. 10 to 50 volts
• B. 100 to 500 volts
• C. 50 to 1000 volts
• D. 5 to 20 volts

Answer: (B)

High-voltage electrical stimulation uses high peak amplitudes to push current through skin and deeper tissues, while keeping the pulses very brief. The typical therapeutic range is about 100 to 500 volts. This higher voltage helps overcome skin and tissue impedance so the current reaches the target tissues effectively, but the short pulse durations limit the total charge per pulse, which helps protect tissues and improve comfort. Lower ranges (10–50 V or 5–20 V) are generally associated with low-voltage modalities and may not penetrate deeply enough. A range extending up to 1000 V would raise safety concerns and isn’t standard in clinical practice. So the voltage range most commonly used for high-voltage stimulation is roughly 100 to 500 volts.
