How is NMES typically administered?

• A. Apply electrode and muscle contraction
• B. Place electrodes on bone
• C. Use only sensory stimulation without contraction
• D. Maintain skin contact without electrode placement

Answer: (A)

NMES works by delivering electrical pulses through electrodes placed over the target muscle to evoke a contraction. The current depolarizes the motor nerves, causing the muscle to contract in a controlled way, which is why NMES is administered by applying electrodes to the muscle (or its motor points) and generating that contraction. Placing electrodes on bone wouldn’t effectively reach the motor fibers, using only sensory stimulation wouldn’t produce a contraction, and simply keeping the skin in contact without electrodes means no current is delivered at all.
