Which statement best describes the motor point in NMES?

• A. A location where a strong current yields contraction
• B. A location where a maximal contraction occurs only with very high current
• C. A location where a minimal current elicits a maximal contraction
• D. A location where muscle is not innervated

Answer: (C)

In NMES, the motor point is the spot over a muscle where the motor nerve fibers are closest to the surface, so only a small amount of current is needed to trigger a contraction. This is why the best description is that a minimal current elicits a maximal contraction. The motor point represents the lowest stimulation threshold with the most efficient recruitment of motor units, helping to produce a strong response with less current and often more comfort for the patient. Other statements imply you must use a lot of current or that the muscle isn’t innervated, which isn’t true; motor points are by definition located over innervated nerves and are characterized by a low current threshold rather than a requirement for very high current.
