Single-Leg Dynamic Balance Training to Improve Stability on Post ACL Reconstruction

Abstract

ACL injuries are a prevalent concern, particularly in athletic populations, leading to significant research efforts aimed at effective treatment and prevention. Previous studies indicate that while surgical reconstruction is common, a considerable percentage of patients do not regain pre-injury sports performance. This highlights the necessity for enhanced rehabilitation strategies focusing on dynamic balance and neuromuscular control. The study involved 90 participants were divided into three groups: a control group receiving conventional ACL rehabilitation. Conventional Rehabilitation, involving muscle strength and endurance exercises, such as stationary biking, straight leg raises, step-ups, hamstring curls, toe raises, partial squats, and wall squats. Single-Leg Dynamic Balance Training, implemented in two stages over six weeks, incorporating modified Romberg exercises, retro walking, balance board exercises, plyometric exercises, and isometric as well as isotonic strengthening exercises for the quadriceps, hamstrings, and hip muscles. The experimental group showed significant improvements in both joint position sense and SEBT scores compared to the control group. Statistical analysis revealed that the joint position sense increased significantly from 25.4 ± 4.91 to 14.93 ± 5.22 (t = 6.653833) in the experimental group, whereas the control group exhibited minimal changes. Similarly, SEBT scores improved significantly in the experimental group from 77.46 ± 5.81 to 70.4 ± 2.29 (t = 6.33956), highlighting the effectiveness of the dynamic balance training. Single-leg dynamic balance training significantly enhances knee stability post-ACL reconstruction. These findings underscore the potential benefits of incorporating targeted balance training into ACL rehabilitation programs to improve patient outcomes and reduce the risk of re-injury.
