FES uses electrical stimulation to restore function by applying to what targets?

• A. Motor nerves
• B. Sensory nerves
• C. Skin
• D. Bones

Answer: (A)

Functional electrical stimulation aims to re-create purposeful movement by activating the motor system. It delivers electrical pulses to nerves that innervate skeletal muscles (peripheral motor nerves) or directly to the muscles themselves, producing contractions that generate functional actions like grasp or stepping. This targets motor pathways to induce movement; stimulating skin would not produce a functional contraction, and stimulating sensory nerves would alter sensation rather than drive a muscle action. So the correct target is motor nerves.
