Which electrical modality is used for muscle re-education?

• A. TENS
• B. Pulsed high-volt
• C. NMES
• D. Interferential

Answer: (B)

Muscle re-education relies on retraining neuromuscular recruitment by producing purposeful muscle contractions through electrical stimulation. The modality that best achieves this is NMES, which delivers pulsed electrical current to activate motor nerves and evoke visible or palpable contractions. This helps retrain the brain–muscle pathways, improve recruitment patterns, and restore functional control after injury, immobilization, or nerve damage. It can be modulated to mimic natural muscle use and paired with patient effort to promote voluntary control. Other currents are primarily used for non-educational goals: TENS and interferential are mainly for pain relief, and pulsed high-volt currents are typically aimed at edema reduction, wound healing, or inflammatory control rather than targeted muscle retraining.
