Is high frequency stimulation generally more comfortable?

• A. Yes, high frequency is more comfortable
• B. No, high frequency is less comfortable
• C. It depends on the person
• D. Frequency has no effect on comfort

Answer: (A)

Comfort with electrical stimulation comes from how the nerves are recruited and the resulting sensation. High-frequency stimulation tends to feel more comfortable because it activates the large-diameter A-beta fibers at lower amplitudes, producing a light, continuous tingling without strong muscle contractions. That smooth sensory input is usually easier to tolerate than the stronger, sometimes cramp-like responses that can accompany lower-frequency stimulation, which often requires higher amplitude to achieve a similar effect. Of course, individual sensitivity and correct settings (pulse width, electrode placement) matter, but in general, higher frequency is more comfortable for most people.
