【摘要】：为了测定并对比机械性踝关节不稳(MAI)患者与功能性踝关节不稳(FAI)患者的腓骨长肌(PL)与胫前肌(TA)激活时间,本研究按照纳入标准纳入45例患者,分为正常、MAI、FAI 3组,每组15名患者,每位均进行踝关节模拟内翻试验及肌电数据采集,计算并对比各组数据。研究表明:相较正常组,MAI组与FAI组患者的患侧踝关节PL、TA激活时间明显延长,差异显著(p0.05);然而MAI与FAI两组间并无显著差异(p0.05)。将患侧与健侧肌肉激活时间进行对比(组内比较),正常组无明显差异(p0.05),MAI与FAI组患侧踝关节PL、TA肌肉激活时间均较对侧显著延长,具有统计学差异(p0.05)。综上,机械性踝关节不稳患者与功能性踝关节不稳患者的腓骨长肌与胫前肌激活时间均延长,两者之间无显著差异,表明MAI患者也存在神经肌肉功能缺陷。本试验为MAI患者的临床针对性治疗提供了科学依据。
[Abstract]:In order to measure and compare the activation time of fibula longus (PL) and tibialis anterior muscle (TA) in patients with mechanical ankle instability (mai) and functional ankle instability (FAI), 45 patients were divided into 3 groups, 15 patients in each group. Each of them was tested by simulated varus test and electromyoelectric data acquisition, calculated and compared the data of each group. The results showed that the activation time of PLTA in the affected ankle joint was significantly longer than that in the normal group and FAI group (p0.05), but there was no significant difference between mai and FAI group (p0.05). There was no significant difference in the time of muscle activation between the affected side and the normal side (p0.05). The activation time of PLTA in the patients with mai and FAI was significantly longer than that in the contralateral (p0.05). In conclusion, the activation time of fibula longus muscle and tibial anterior muscle in patients with mechanical ankle instability and functional ankle instability were prolonged, and there was no significant difference between the two groups, indicating that there were also neuromuscular functional defects in patients with mai. This experiment provides a scientific basis for the clinical targeted treatment of mai patients.
