Figure 1From: Muscle motor point identification is essential for optimizing neuromuscular electrical stimulation useSchematic representation of a mixed peripheral nerve and two stimulation sites. When the active electrode precisely overlies the motor point (MP), less current is required to excite the motor axons and thus to elicit the muscle contraction. Alternatively, stimulation on the other site (non-MP) requires higher current intensity to reach the motor branch, with possible excitation of the sensory fibers conveying pain.Back to article page
