【摘要】：背景:预防前十字韧带损伤对运动员非常重要,动态膝关节外翻被认为是导致非接触性前十字韧带损伤的危险因素之一,但髋关节外展肌群和后足的功能能否增加动态膝关节外翻的相关研究较少。通过二维视频分析筛选测试能检验髋关节外展肌和后足功能,包括由此影响动态膝关节外翻的因素。本研究旨在探索髋关节外展肌和后足动态校准与动态膝关节外翻间的关系。方法:该横断面研究招募来自9所高中的130名女篮运动员(258条腿)。让运动员进行单腿下蹲和单腿落地动作,通过二维视频图像记录膝关节斜收(KID)和髋关节探出(HOD)的距离。用动态Trendelenburg卧位测试(DTT)和动态足后跟—地板测试(HFT)评估髋关节外展肌和后足的动态校准。结果:卡方检验显示,单腿下蹲(28.7%)和单腿落地(23.3%)两个动作相比,DTT阳性分布无显著差异,单腿落地(51.4%)HFT阳性分布显著大于单腿下蹲动作(31.0%,p0.01)。DTT阳性组单腿下蹲和单腿落地的KID值均大于DTT阴性组(15.1±5.4 cm vs.20.2±7.5 cm,p0.001),DTT阳性组的HOD值也更大(15.2±1.9 cm和17.6±2.8 cm,p0.001)。HFT阳性组单腿下蹲和单腿落地的KID值大于HFT阴性组(12.2±5.1 cm,p0.01;14.7±7.2 cm,p0.001),但两组HOD值无显著差异。结论:动态髋关节不良校准可能与KID和HOD有较强相关,而后足外翻只与KID有较强相关。髋关节外展肌和后足动态校准功能紊乱是导致动态膝关节外翻的重要因素,通过评估DTT和HFT将有助于预防动态膝外翻。
[Abstract]:Background: prevention of anterior cruciate ligament injury is very important for athletes. Dynamic knee valgus is considered to be one of the risk factors leading to non-contact anterior cruciate ligament injury. However, there are few studies on whether the function of abductor muscle and hind foot can increase the dynamic valgus of the knee joint. The function of abductor muscle and hind foot of hip joint can be tested by two dimensional video screening test, including the factors that affect the dynamic valgus of knee joint. The purpose of this study was to explore the relationship between the dynamic calibration of abductor muscle and hind foot and the dynamic valgus of the knee joint. Methods: the cross-sectional study recruited 130 women basketball players (258 legs) from 9 high schools. The athletes were allowed to perform one-legged squatting and one-legged landing, and the distance between knee joint oblique (KID) and hip joint (HOD) was recorded by two dimensional video images. Dynamic calibration of hip abductor muscle and hind foot was evaluated by dynamic Trendelenburg (DTT) and dynamic heel floor test (HFT). Results: chi-square test showed that there was no significant difference in DTT positive distribution between single leg squat (28. 7%) and single leg landing (23. 3%). The positive distribution of HFT in single leg landing (51.4%) was significantly higher than that in single leg squat (31.0%) and single leg landing (KID) in). DTT positive group was higher than that in DTT negative group (15.1 卤5.4 cm vs.20.2 卤7.5 cm,). The HOD value of p0.001), DTT positive group was higher than that of HFT negative group (15.2 卤1.9 cm and 17.6 卤2.8 cm,p0.001). HFT positive group). The KID value of single leg squatting and single leg landing group was higher than that of HFT negative group (12.2 卤5.1 cm,p0.01;). However, there was no significant difference in HOD between the two groups. Conclusion: dynamic hip maladjustment may be strongly correlated with KID and HOD, and hindfoot valgus is only strongly correlated with KID. The dynamic calibration disorder of abductor muscle and hind foot of hip joint is an important factor leading to dynamic knee valgus. The evaluation of DTT and HFT will help to prevent dynamic knee valgus.
