What is the evidence for NMES after ACL reconstruction?

• A. No evidence supporting NMES
• B. Moderate evidence supporting NMES
• C. Strong evidence to support NMES to increase quad strength and short-term functional outcomes
• D. NMES is contraindicated after ACL reconstruction

Answer: (C)

Quadriceps activation is often reduced after ACL reconstruction, so using NMES aims to boost muscle contractions when voluntary drive is limited. This external stimulation helps preserve and rebuild quadriceps strength earlier in rehabilitation, which in turn supports safer progression through range-of-motion and strengthening exercises. Because the primary goal after ACL reconstruction is to regain quadriceps strength to enable functional recovery, NMES has consistently shown larger gains in quadriceps strength and better short-term functional outcomes compared with rehab alone. Large and well-designed studies synthesize to a strong overall conclusion: NMES is a beneficial adjunct in the early postoperative period for improving quad strength and short-term function. While some aspects of long-term functional advantage vary across studies, the strongest, most reliable finding is the early strength and function benefit, which is why this option is considered the best answer.
