For NMES rotator cuff strengthening, what intensity is used?

• A. Moderate
• B. No contraction
• C. Maximal tolerable with visible contraction causing movement of the arm against the strength
• D. Minimal tolerable

Answer: (C)

The main idea is that strengthening with NMES requires a strong, visible contraction that actually moves the shoulder against resistance. You want to push the intensity to the patient’s maximal tolerable level so the rotator cuff produces a robust, often tetanic, contraction rather than a faint twitch or no contraction at all. Submaximal or no contraction won’t recruit enough motor units to drive strength gains, and a contraction without movement isn’t providing a meaningful strengthening stimulus. So the best choice is using maximal tolerable intensity that yields a visible contraction with arm movement against resistance.
