摘要：

      摘要 目的：研究全身振动训练对膝关节前交叉韧带损伤（ACL）重建术后患者下肢肌力和运动控制的影响。 方法：选取符合纳入标准的40例前交叉韧带损伤重建术后患者为研究对象，所有患者术后12周进行常规康复训练。第13周开始将患者用数字法随机分为对照组和试验组，每组20例。对照组继续给予常规康复训练，试验组在对照组的基础上，加入每天1次，每次10min，每周5次，持续4周的全身振动训练。两组患者第12周和第16周，均进行等速肌力测试训练系统膝关节屈伸肌群的峰力矩、拮抗肌比值检测和动态平衡仪中本体感觉评估。 结果：①两组患者膝关节屈伸峰力矩，治疗前后和治疗后组间对比均有显著性差异（P＜0.05）；②两组患者动态平衡测试的平均轨迹误差值，治疗前后和治疗后组间对比有显著性差异（P＜0.05）。 结论：全身振动训练能够促进ACL重建术后患者的下肢肌力和运动控制的恢复。

Abstract:

      Abstract Objective: To compare the effects of whole-body vibration training (WBVT) with conventional training (CT) program on strength and motor control of lower limb after anterior cruciate ligament (ACL) reconstruction. Method: Forty patients with ACL reconstruction were randomly divided into WBVT group or CT group. The two groups were treated with the conventional training immediately after ACL-reconstruction for 12 weeks, since the 13th week after ACL reconstruction, the patients in WBVT group were treated with CT program added WBVT 10min per day for 4 weeks. The motor control function was measured with balance system; the peak torque of knee flexion and extension and the antagonistic muscle ratio were measured by ISOMED2000 pre-intervention and post-intervention at the 12th and 16th week. Result: ① The pre-intervention and post-intervention peak torque of knee flexion and extension had significant difference, the peak torque between the two groups after treating also had significant difference (P＜0.05). ② The pre-intervention and post-intervention average trace error（ATE） in dynamic balance test had significant difference, the ATE between the two groups after treating also had significant difference (P＜0.05). Conclusion: WBVT can improve the strength of knee and the lower limb motor control function of patients with ACL reconstruction.
