前交叉韧带重建术后运动员等速肌力训练的研究

摘要

To evaluate the influence of rehabilitation program on the muscle power of athletes with anterior cruci-ate ligament rupture after the reconstruction,and measure the muscle strength after training by isokinetic muscle strength system.Methods Subjects were assigned randomly to either exercise group(n=15,isokinetic exercises)or control group(n=15,commonly exercises).Both groups received rehabilitation training after ACL reconstruction.Sub-jects were assessed with isokinetic measurement after 12 and 24 weeks postoperation.Results After operation 12 and 24 weeks of constant speed strength training,the exercise group in 60°/s,120°/s test flex and extent peak torque has a different degree of growth,were significantly higher than that in control group (P<0.05).Conclusion Isokinetic strength training of rehabilitation for recovery of muscle function after ACL reconstruction has good promoting effect, worthy of further promotion.%目的：采用等速肌力锻炼系统对膝关节前交叉韧带重建术后运动员进行康复训练，通过测量肌肉力量评估等速肌力训练对运动员术后恢复的作用。方法选择2014年3月至2015年12月膝关节前交叉韧带（anterior cru-ciate ligament，ACL）断裂、需行重建手术的30例运动员患者纳入研究，其中男26例，女4例，年龄16～23岁，受伤至手术时间1～6．5个月。随机分成训练组15例（等速训练患侧肌力）和对照组15例（常规康复训练）并分别进行功能训练，在术后第12、24周进行肌力测试。结果术后12周、24周训练组在60°／s、120°／s测试屈肌及伸肌峰力矩值都有明显高于对照组，差异有统计学意义（P＜0．05）。结论等速康复力量训练对运动员 ACL重建术后肌肉功能恢复有较好的促进作用，值得进一步推广。
