Neuromuscular Electrical Stimulation for Quadriceps Strength After ACL Surgery .
Effects of Neuromuscular Electrical Stimulation on Quadriceps Femoris Muscle Strength and Knee Joint Function in Patients After ACL Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Trials.
Orthop J Sports Med . 2025 Jan 13;13(1):23259671241275071.Eleven randomized controlled trials including 402 patients who underwent ACL reconstruction or repair were included in this systematic review and meta-analysis comparing NMES-assisted rehabilitation versus standard physical therapy alone. Pooled outcomes analyzed included quadriceps muscle strength and knee joint function (Lysholm scores). The meta-analysis revealed significant improvement in quadriceps muscle strength at both short-term (≤6 weeks) and long-term follow-ups with NMES compared to standard rehabilitation. These findings suggest that early initiation of NMES significantly enhances quadriceps strength recovery, highlighting NMES as beneficial adjunct therapy following ACL surgery.
