【摘要】：目的:探讨膝关节内侧移位(MKD)的发生机制,为进一步完善膝关节损伤的防治方案提供依据。方法:从男性青年志愿者中选取膝关节内侧移位(MKD)组30例和正常对照组30例,用标准量角器测量各组踝背屈被动活动范围(PROM)并进行比较,用表面肌电测试系统测试单腿下蹲过程中内侧腓肠肌、外侧腓肠肌和胫前肌的表面肌电图,比较两组间的肌电图均方根振幅(RMS)。结果:MKD组踝背屈PROM明显小于正常对照组(P0.05);MKD组单腿下蹲时内侧腓肠肌、外侧腓肠肌和胫前肌肌电RMS均明显高于正常对照组(P0.01,P0.05,P0.01)。结论:膝关节内侧移位的发生机制之一可能是踝背屈活动受限和腓肠肌/胫前肌的共激活,对膝关节损伤的防治应设法降低腓肠肌、胫前肌的激活强度,增加踝关节的活动范围。
[Abstract]:Objective: to explore the mechanism of medial displacement of knee joint (MKD) and to provide evidence for further improvement of the prevention and treatment of knee joint injury. Methods: 30 cases of medial displacement of knee joint MKD group and 30 cases of normal control group were selected from male young volunteers. The surface electromyography (EMG) of medial gastrocnemius, lateral gastrocnemius and tibial anterior muscle was measured by the surface electromyography (EMG) test system in the course of single leg squat. The mean square root amplitude of electromyography (EMG) was compared between the two groups. Results the RMS of medial gastrocnemius muscle, lateral gastrocnemius muscle and tibial anterior muscle in the control group was significantly higher than that in the normal control group (P 0.01), and the RMS of the lateral gastrocnemius and tibial anterior muscle was significantly higher than that of the normal control group. Conclusion: one of the possible mechanisms of medial displacement of knee joint may be the limitation of ankle dorsiflexion and coactivation of gastrocnemius / tibial anterior muscle. The prevention and treatment of knee joint injury should try to reduce the activation intensity of gastrocnemius and tibialis anterior muscle. Increase the range of ankle motion.
