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这种重复损伤的易感性知之甚少。在以前的研究中，重复性研究建立了可靠测量与运动员踝关节损伤易感性有关的因素的能力。这项为期四年的研究的目的是建立在这些早期研究的基础上，并对踝关节损伤的危险因素进行全面调查。将对大约666名没有重大踝关节创伤史且不使用支具或胶带的大学预科或大学运动员进行前瞻性研究。其中包括参加足球、长曲棍球和曲棍球以及篮球和网球的男子和女子。评价将基于初步研究和其他研究提出的潜在风险因素、人口统计学信息、形态测量学、踝关节松弛、足和踝关节的解剖对线、等速踝关节力量、姿势稳定性以及对足部矢状面和额状面扰动的肌肉反应时间。然后将跟踪每个运动员，以记录他们对训练和比赛的接触。使用这些数据，一个或多个内在风险因素将用于预测哪些个体踝关节韧带创伤的风险增加，并描述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.
