How does amplitude relate to contraction strength and comfort in NMES?

Explanation:
Amplitude is the intensity of the electrical stimulus. As you increase amplitude, more motor neurons are recruited, producing a stronger, more forceful contraction. But higher amplitude also stimulates more sensory fibers and can provoke more discomfort, limiting how high you can safely go. So you get a trade-off: enough amplitude to achieve the desired contraction, but not so high that it becomes intolerable. Other settings like pulse duration and frequency influence both strength and comfort, but the direct relationship is that higher amplitude strengthens contraction while potentially increasing discomfort.
