What is a typical session duration for an NMES strengthening protocol?

• A. 5 to 10 minutes.
• B. 15 to 45 minutes.
• C. 60 to 90 minutes.
• D. 2 to 5 minutes.

Answer: (B)

Strength gains from NMES come from delivering enough muscle contractions in a session while keeping fatigue and tissue stress in check. A typical strengthening protocol uses sessions in the 15 to 45 minute range because this duration provides enough contraction time and overall stimulus to drive adaptations without overfatiguing the muscle or causing excessive discomfort. Shorter sessions, like five to ten minutes, usually don’t accumulate enough training volume to produce meaningful strength gains, while longer sessions—sixty minutes or more—tend to increase fatigue and irritation without delivering proportional benefits. This 15–45 minute window also fits practical clinic and home-use schedules, allowing for proper ramping, rest breaks, and progression across treatment sessions.
