What is NMES and its primary therapeutic goal?

• A. Neuromuscular electrical stimulation: uses pulsed current to evoke muscle contractions for strengthening, re-education, or preventing atrophy.
• B. Tens for pain relief.
• C. Electrical stimulation to modulate autonomic function.
• D. Electrical stimulation for wound healing.

Answer: (A)

NMES, or neuromuscular electrical stimulation, uses a pulsed electrical current to activate motor nerves and produce skeletal muscle contractions. The main goal is to evoke contractions that strengthen weak muscles, help re-educate motor patterns after injury or nerve damage, and prevent or minimize atrophy from disuse. By directly engaging the muscle, NMES supports functional strength and motor control when voluntary activation is limited. This differs from other electrical modalities: TENS targets sensory nerves for pain relief rather than inducing contractions, other forms aim to modulate autonomic function, and wound-healing currents focus on tissue repair rather than activating skeletal muscle.
