等速肌力训练结合Pro-kin平衡系统用于膝关节前交叉韧带重建术后的临床观察

Clinical observation of isokinetic muscle strength training combined with Pro-kin balance system for postoperative reconstruction of the anterior cruciate ligament of the knee joint

目的探讨等速肌力训练结合Pro-kin平衡系统用于膝关节前交叉韧带(ACL)重建术后的临床疗效。方法选取2020年8月—2022年12月无锡市第九人民医院68例行ACL重建术的患者为研究对象,依据随机双盲法为观察组与对照组,每组34例。对照组在常规康复训练基础上进行等速肌力训练,观察组在对照组基础上结合Pro-kin平衡系统进行干预。比较两组患者干预前后屈曲及伸展关节活动度、下肢肌力[伸肌峰力矩(EPT)、屈肌峰力矩(FPT)、屈/伸肌群峰力矩比值(H/Q)]、膝关节功能[Holden功能性步行量表(FAC)、国际膝关节评分委员会(IKDC)评分、Lysholm评分、恐动症Tampa评分(TSK)]评估及下肢平衡功能[人体压力中心(COP)时间稳定性、闭眼压力中心速度(COPS)、单腿COPS、稳定极限面积(COPA)和膝关节反应时间]评估。结果两组干预前后屈曲及伸展关节活动度、EPT、FPT、H/Q、FAC评分、IKDC评分、Lysholm评分、TSK评分、COP时间稳定性、闭眼COPS、单腿COPS、COPA、膝关节反应时间的差值比较,差异均有统计学意义(P<0.05),观察组干预前后上述各指标的差值均高于对照组。结论等速肌力训练结合Pro-kin平衡系统用于ACL重建术后的康复训练,可有效改善患者膝关节功能和下肢平衡能力,恢复下肢肌群肌力。

Objective To explore the clinical efficacy of isokinetic muscle strength training combined with the Pro-kin balance system in postoperative rehabilitation following anterior cruciate ligament(ACL)reconstruction.Methods Sixty-eight patients who underwent ACL reconstruction surgery at The Ninth People's Hospital of Wuxi from August 2020 to December 2022 were selected as the research subjects.According to a randomized double-blind method,they were divided into an observation group and a control group,with 34 cases in each group.The control group received isokinetic muscle strength training on the basis of routine rehabilitation training,while the observation group received intervention combining the Pro-kin balance system with the training in the control group.The flexion and extension joint range of motion,lower limb muscle strength[peak torque of extensor muscles(EPT),peak torque of flexor muscles(FPT),and hamstring/quadriceps(H/Q)peak torque ratio],knee joint function[Holden Functional Ambulation Categories(FAC),International Knee Documentation Committee(IKDC)score,Lysholm score,Tampa Scale for Kinesiophobia(TSK)],and lower limb balance function[center of pressure(COP)time stability,closed-eye COP speed(COPS),single-leg COPS,stable limit area(COPA),and knee joint reaction time]were compared between the two groups before and after intervention.Results The differences in flexion and extension joint range of motion,EPT,FPT,H/Q,FAC score,IKDC score,Lysholm score,TSK score,COP time stability,closed-eye COPS,single-leg COPS,COPA,and knee joint reaction time before and after intervention were statistically significant in both groups(P<0.05).The differences in these indicators between the observation group and the control group were higher in the observation group.Conclusion Isokinetic muscle strength training combined with the Pro-kin balance system for rehabilitation training after ACL reconstruction surgery can effectively improve knee joint function and lower limb balance ability,and restore lower limb muscle strength.
