Longer ramp times in NMES are mainly intended to improve?

• A. Contraction strength
• B. Treatment duration
• C. Electrode placement accuracy
• D. Comfort

Answer: (D)

Longer ramp times in NMES are used to improve comfort during stimulation. When the current rises gradually instead of switching on abruptly, the skin and underlying nerves experience a gentler sensation and the initial muscle contraction occurs more smoothly. This reduces how uncomfortable the stimulus feels and lowers the chance of reflex withdrawal or pain, making the therapy more tolerable for the patient. That improved comfort generally leads to better tolerance, allowing longer or more frequent sessions.

Contraction strength is mainly driven by the amplitude, pulse width, and frequency, not how slowly the current ramps up. Treatment duration and electrode placement accuracy are determined by the overall protocol and placement technique, not ramp time.
