前交叉韧带重建术后患者的等速肌力训练和疗效评定

目的:研究用Biodex system 3多关节等速肌力评定及训练系统对ACL重建术后患者肌力的影响。方法:将50例行ACL重建术后的患者随机分成试验组25例(等速训练患侧肌力)和对照组25例(等张训练患侧肌力)并分别进行功能训练,在术后第12、24周进行等速向心肌力测试。结果:术后第12、24周对患者进行膝关节等速向心肌力测试,试验组膝屈、伸肌患侧峰力矩/健侧峰力矩比值明显高于对照组,差异具有显著性(P<0.05),试验组在30°时的股内侧肌患侧峰力矩/健侧峰力矩比值明显高于对照组,差异具有显著性(P<0.05)。结论:通过等速训练进行系统的康复治疗可使膝关节ACL重建术后的患者短期(6个月)达到健侧屈伸肌力水平,并能达到运动水平。

Isokinetic knee flexion- and extension-strength exercises and evaluation after anterior cruciate ligament reconstruction

Objective:To study the effects of training flexion and extension of knee muscles on Biodex Multi-Joint System in ACL reconstruction patients. Method: Subjects were assigned randomly to either experimental group(n=25,isokinetic exercises) or control group(n=25,isotonic exercises). Both groups received rehabilitation training after ACL reconstruction. Subjects were assessed with isokinetic measurement after 12 and 24 weeks postoperation. Result:In experimental group involved peak touque/uninvolved peak torque ratio were significantly higher than that in control group (P<0.05), In experimental group involved touque/uninvolved torque ratio at flexion 30°of knee were significantly higher than that in control group(P<0.05). Conclusion:The knee muscles flexion- and extension-strength of patients in experimental group had significant improvement when compared with the control group after 6 month postoperation. After isokinetic training patients can return to sport.
