Effect of Visual-Guided Balance Training on Knee Motor Function and Biomechanical Characteristics After ACL Reconstruction

Condition(s) studied

Investigational drug(s) / intervention(s)

Traditional group: Based on the traditional standardized rehabilitation program, additional universal balance training content has been added. Starting from the 5th week after the surgery and continuing until the 14th week, three times a week for a total of 10 weeks, the training duration was one and a half hours each time.

Intervention Group: Based on the conventional standardized rehabilitation program, add the content of visual-guided balance training.Starting from the 5th week after the surgery and continuing until the 14th week, three times a week for a total of 10 weeks, the training duration was one and a half hours each time.

Study summary

This study aims to investigate the improvement effect of visual-guided balance training on the knee joint function and gait performance of patients after ACLR, and to clarify the advantages of this training program compared to conventional rehabilitation training; at the same time, by including healthy individuals as the control group, it quantifies the differences in knee joint function and gait performance between patients after ACLR and healthy individuals, to verify whether visual-guided balance training can more effectively narrow the functional gap between patients after ACLR and healthy individuals, and promote the recovery of patients' knee joint function and gait closer to the healthy level. Ultimately, it provides scientific theoretical basis and practical guidance for the optimization of the rehabilitation plan after ACLR, and helps patients achieve comprehensive and high-quality recovery.

Eligibility

Primary outcome measure(s)

• Vicon 3D Gait Testing — Preoperative baseline; 14 weeks after the operation; 6 months after the operation
  The subjects first underwent a static test, and then chose to perform tests of slow jogging, walking and single-leg balance at their own pace. Observe the three-dimensional plane joint angles（degree) of each joint in the lower limbs.
• Vicon 3D Gait Testing — Preoperative baseline; 14 weeks after the operation; 6 months after the operation
  The subjects first underwent a static test, and then chose to perform tests of slow jogging, walking and single-leg balance at their own pace. Observe the three-dimensional plane joint torques (BW×BH）of each joint in the lower limbs.
• Vicon 3D Gait Testing — Preoperative baseline; 14 weeks after the operation; 6 months after the operation
  After a static trial, participants performed self-paced tests of slow jogging, walking, and single-leg balance while three-dimensional ground reaction forces （BW)at each lower-limb joint were recorded.
• isokinetic muscle strength — Preoperative baseline;14 weeks after the operation; 6 months after the operation
  This isokinetic muscle strength test selected two angular velocities: 60°/second (slow speed) and 180°/second (medium speed). Observe the relative peak torque （ N·m/kg）of the quadriceps and hamstring muscles.
• isokinetic muscle strength — Preoperative baseline;14 weeks after the operation; 6 months after the operation
  This isokinetic muscle strength test selected two angular velocities: 60°/second (slow speed) and 180°/second (medium speed).Observe the limb symmetry index（%） of the quadriceps and hamstring muscles.
• isokinetic muscle strength — Preoperative baseline;14 weeks after the operation; 6 months after the operation
  This isokinetic muscle strength test selected two angular velocities: 60°/second (slow speed) and 180°/second (medium speed).Observe the hamstring-to-quadriceps peak-torque ratio (H/Q).
• Imoove Balance Training Tester — Preoperative baseline; 4 weeks after the operation; 14 weeks after the operation; 6 months after the operation
  The dynamic balance ability of the subjects was evaluated. The main observations included the imbalance percentage, the score of the green target, coordination, stability, distribution balance, and the total score. The score ranged from 0 to 100, with a higher score being better.
