About

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.

30 participants in 2 patient groups

Neuromuscular Training (NMT) plus Standard Basketball Training

Experimental group

Description:

Participants in this arm will receive a 12-week neuromuscular training (NMT) program in addition to their regular basketball training. The NMT program will include balance tasks, jump-landing drills, agility exercises, and core strengthening. Sessions will be conducted in parallel with standard basketball practice.

Treatment:

Behavioral: Neuromuscular Training (NMT)

Standard Basketball Training

No Intervention group

Description:

Participants in this arm will continue their usual basketball training program for 12 weeks without additional neuromuscular training. Training content and schedule will follow standard team practice routines. This arm will serve as a comparator to evaluate the added effect of NMT.
