Effect of balance promotion training on knee proprioception after reconstruction of knee anterior cruciate ligament injury

Objective: To study the effect of balance promotion training on knee proprioception after reconstruction of knee anterior cruciate ligament(ACL) injury.Method: A total of 124 cases after reconstruction of ACL injury were selected.All patients administered routine postoperative rehabilitation training for 12 weeks.At the 12th week postoperation,all patients were equally randomized into training group and control group.Training group proceeded balance promotion training at the 12th—16th week post operation at the same period control group continued strength and gait training.Assessment of balance function were evaluated with professional balance function system (PC708) at the 12th week and 16th week three was no significant difference.Result: At the 16th week the measurement showed: ①At eyes opened state,between training group and control group in the LFS index and the size of the area covering 90% of oval region(P0.05).②At eyes closed state,the difference between training group and control group in the LFS index and the size of the area covering 90% of oval region was statistically significant(P0.05).Conclusion: The balance promotion training after reconstruction of ACL injury,the knee joint proprioception of patients could significantly enhanced.
