Knee injuries with interior cruciate ligament rupture or strain are one of more common and more complicate ones for diagnosis, operation and multistage rehabilitation. The purpose of this study was assessment of force - velocity parameters of knee flexors and extensors in patients 13 weeks after anterior cruciate ligament reconstruction.
13 men, aged 18- 34 years participated in this research. Anterior cruciate ligament reconstruction in 4 Polyclinic in Wrocław was carried out in each subjects. Assessment of force-velocity parameters of knee flexors and extensors both limbs in isokinetic conditions (in 180 degrees /s loads) was performed in all subjects. Each subject had to perform 5 flexion and extension movements in the knee in the sagittal plane. It was necessary for the subject to develop the peak torque in the shortest time possible, in each movement.
Significant statistically deficits of peak torque, maximum work and average power was obtained in injury limb. The registered deficit exceeded the 30% for all measured values.
After ACL reconstruction functional deficiency relates first of all to the quadriceps femoris what is confirmed by the higher H/Q ratio in peak torque compare to the healthy limb. Although low number of subjects participating in the study results of tests demonstrates reliable assessment of knee muscles' function in patients after ACL reconstruction allows calculation of deficit levels of force - velocity parameters and ipso facto possibility to select optimal rehabilitation program for each patient.
伴有内侧交叉韧带断裂或拉伤的膝关节损伤是诊断、手术及多阶段康复中较为常见且复杂的损伤之一。本研究旨在评估前交叉韧带重建术后13周患者膝关节屈伸肌的力-速度参数。
13名年龄在18至34岁之间的男性参与了本研究。在弗罗茨瓦夫的4家综合诊所对每位受试者进行了前交叉韧带重建。对所有受试者在等速条件下(180度/秒负荷)双侧膝关节屈伸肌的力-速度参数进行评估。每位受试者必须在矢状面内进行5次膝关节屈伸运动。受试者在每次运动中都必须在尽可能短的时间内产生峰值扭矩。
患侧在峰值扭矩、最大功和平均功率方面存在显著的统计学缺陷。所有测量值的记录缺陷均超过30%。
前交叉韧带重建术后的功能缺陷首先与股四头肌有关,这一点通过与健侧相比峰值扭矩中更高的H/Q比值得到证实。尽管参与研究的受试者数量较少,但测试结果表明,对前交叉韧带重建术后患者膝关节肌肉功能的评估是可靠的,能够计算力-速度参数的缺陷水平,从而为每位患者选择最佳康复方案。
