In NMES, typical ramp time value is what?

• A. 2-4 seconds
• B. 1-2 seconds
• C. 0-0.5 seconds
• D. 5-6 seconds

Answer: (B)

Ramp time in NMES refers to how long it takes for the current to rise from zero to the target intensity at the start of a stimulation burst. A value of about 1–2 seconds provides a gradual, comfortable onset of muscle contraction, which helps recruit motor units smoothly and reduces the abrupt sensation that can be painful or startle the patient. This balance supports effective therapeutic activation without excessive discomfort or fatigue.

Shorter ramps, like 0–0.5 seconds, produce a very rapid contraction that can be painful or uncomfortable and may hinder patient tolerance. Longer ramps, such as 2–4 seconds or 5–6 seconds, slow the onset too much, making the session inefficient and potentially reducing the acute training effect.
