On:off ratio for NMES re-ed?

• A. 2:1 or rest
• B. 1:1 or movement
• C. 3:1
• D. 1:2

Answer: (B)

In NMES re-education, the On:Off ratio sets how long you stimulate a muscle versus how long you rest between stimulations. For re-educating movement, you want repeated, controlled contractions with enough rest to avoid quick fatigue, so the rhythm supports motor learning and task practice.

A 1:1 ratio, meaning equal durations of stimulation and rest, is best because it provides a steady, manageable cycle that promotes movement practice without excessive fatigue. Longer on-times (like 2:1 or 3:1) fatigue the muscle more quickly, reducing the ability to repeat contractions for practice. Longer rest times (like 1:2) cut the training dose and disrupt the rhythm of movement drills.

So, the most effective approach for NMES re-education is a 1:1 ratio to support ongoing, functional movement during training.
