Typical ramp times for NMES are in what range?

• A. 5-6 seconds
• B. 0.1-0.3 seconds
• C. 3-4 seconds
• D. 1-2 seconds

Answer: (D)

In NMES, ramp time is the pause that lets the current rise smoothly from zero to its peak, so the muscle contraction begins gradually rather than abruptly. A 1–2 second ramp is typical because it creates a comfortable, controlled onset of contraction for most patients, improving tolerance and allowing a more functional, usable movement pattern. If the ramp is too quick (like 0.1–0.3 seconds), the contraction can feel sudden and painful, making it hard for the patient to tolerate. If the ramp is too slow (several seconds, such as 3–4 or 5–6 seconds), the contraction comes on too gradually, which can hinder timing and increase treatment duration without added benefit. So, 1–2 seconds strikes a practical balance for most NMES applications.
