Effect of Visual-Guided Balance Training on Knee Motor Function and Biomechanical Characteristics After ACL Reconstruction
Peking University Third Hospital
45 participants
Nov 22, 2025
INTERVENTIONAL
Conditions
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.

Interventions
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.
