简要总结
Basketball players often injure the anterior cruciate ligament (ACL), a key structure that stabilizes the knee. Even after surgery and standard rehabilitation, many athletes continue to have problems with knee stability, movement control, and performance during jumping and landing. These issues increase the risk of re-injury and can limit their ability to return to competition.
Neuromuscular training (NMT) is a type of exercise program that focuses on improving balance, muscle coordination, and movement patterns. It uses activities such as jump-landing drills, balance tasks, agility exercises, and core training. Previous research shows that NMT can help athletes land more safely, reduce harmful knee movements, and improve sport performance. However, little is known about its long-term benefits in college basketball players who are more than one year post-ACL surgery.
This study aims to evaluate whether a 12-week NMT program, added to standard basketball training, can improve knee biomechanics, stability, and performance in college basketball players with a history of ACL reconstruction. Thirty participants will be randomly assigned to either an NMT group or a control group. Both groups will complete basketball training, but only the NMT group will receive the additional neuromuscular exercises.
Knee movement will be measured using 3D motion capture and force plates, and performance will be tested through vertical jumps and other sport-specific tasks. The main outcomes will include knee angles during landing, ground reaction forces, dynamic stability, and jump height.
The expected outcome is that athletes who undergo NMT will demonstrate safer landing strategies, better knee control, and improved performance compared to those who only receive standard basketball training. These findings may help coaches and healthcare providers design safer, more effective rehabilitation programs for athletes after ACL surgery.

结局指标
主要结局
Peak knee valgus angle during single-leg jump-landing (degrees)
时间窗: Baseline (pre-intervention) and 12 weeks (post-intervention)
Knee valgus angle will be measured using 3D motion capture during a standardized single-leg jump-landing task. The primary endpoint is the peak knee valgus angle (°) during the landing phase, averaged across 3 successful trials.
次要结局
- Center of pressure displacement after landing, anterior-posterior (millimeters)(Baseline (pre-intervention) and 12 weeks (post-intervention))
- Time to stabilization after landing (seconds)(Baseline (pre-intervention) and 12 weeks (post-intervention))
- Center of pressure displacement after landing, medial-lateral (millimeters)(Baseline (pre-intervention) and 12 weeks (post-intervention))
- Countermovement jump height (centimeters)(Baseline (pre-intervention) and 12 weeks (post-intervention))
- Peak knee flexion angle during single-leg jump-landing (degrees)(Baseline (pre-intervention) and 12 weeks (post-intervention))
- Knee flexion angle at initial contact during single-leg jump-landing (degrees)(Baseline (pre-intervention) and 12 weeks (post-intervention))
- Squat jump height (centimeters)(Baseline (pre-intervention) and 12 weeks (post-intervention))
- Peak vertical ground reaction force during single-leg jump-landing (Newtons)(Baseline (pre-intervention) and 12 weeks (post-intervention))
