What is the ramp time range for Russian stimulation and pulsed NMES?

• A. 0.5-1 second
• B. 6-8 seconds
• C. 1-5 seconds
• D. 10 seconds

Answer: (C)

Ramp time is the period it takes for the stimulator to rise from zero to the set intensity at the start of a stimulation burst. In Russian stimulation and other pulsed NMES, choosing a ramp time helps recruit motor units gradually and makes the contraction more comfortable for the patient. A ramp range of 1 to 5 seconds strikes a balance: it provides a smooth buildup so the user doesn’t feel an abrupt, shocking contraction, while still allowing the muscle to reach the target intensity in a practical timeframe. If the ramp is too short (like 0.5–1 second), the contraction can feel abrupt and uncomfortable. If it’s too long (6–8 or 10 seconds), the contraction onset is delayed, reducing training efficiency and potentially increasing fatigue. Clinically, many clinicians aim for around 2–3 seconds, adjusting toward the lower end for sensitivity and toward the higher end for better tolerance, within the 1–5 second range.
