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

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...

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

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.
