PROSPECTIVE STUDY OF ANKLE INJURY RISK FACTORS

描述：（改编自研究者摘要）踝关节韧带损伤非常常见，占所有运动损伤的28%。然而，对这些损伤的危险因素或对此类重复损伤的易感性知之甚少。在之前的研究中，一项可重复性研究建立了可靠测量运动员踝关节损伤易感性因素的能力。这项为期四年的研究的目的是在这些早期研究的基础上，对踝关节损伤的危险因素进行全面的调查。大约666名大学前或大学运动员，没有明显的踝关节创伤史，没有使用支架或胶带，将进行前瞻性研究。其中包括参加足球、长曲棍球、曲棍球以及篮球和网球的男女运动员。评估将基于初步研究和其他研究提出的潜在危险因素、人口统计学信息、形态测量学、踝关节松弛、足部和踝关节的解剖排列、踝关节等速力量、姿势稳定性以及足部矢状面和额平面扰动时的肌肉反应时间。然后将跟踪每位运动员，记录他们对训练和比赛的接触情况。利用这些数据，一个或多个内在风险因素将被用来预测哪些人踝关节韧带损伤的风险增加，并表征内在风险因素影响的性别差异。

DESCRIPTION: (adapted from Investigator's abstract) Ankle ligament injuries are extremely common, accounting for up to 28% of all athletic injuries. However, little is known about risk factors for these injuries or for susceptibility to repeated injuries of this kind. In previous studies, a repeatability study established the ability to reliably measure the factors that have been implicated in predisposing an athlete to ankle injury. The purpose of this four year study is to build upon these earlier studies and perform a comprehensive investigation of ankle injury risk factors. Approximately 666 pre-collegiate or collegiate athletes with no history of significant ankle trauma and who use no bracing or taping will be studied prospectively. These include males and females participating in soccer, lacrosse and field hockey, as well as in basketball and tennis. Evaluation will be based on potential risk factors suggested by preliminary and other studies, demographic information, morphometry, ankle joint laxity, anatomic alignment of the foot and ankle, isokinetic ankle strength, postural stability, and muscle reaction time in response to sagittal and frontal plane perturbations of the foot. Each athlete will then be followed in order to document their exposure to practices and games. Using these data, one or a combination of intrinsic risk factors will be used to predict which individuals are at increased risk for ankle ligament trauma and to characterize gender differences in the effects of intrinsic risk factors.
