PROSPECTIVE STUDY OF ANKLE INJURY RISK FACTORS

描述：(改编自调查者摘要)脚踝韧带损伤非常常见，占所有运动损伤的28%。然而，人们对这些损伤的危险因素或对这种反复损伤的易感性知之甚少。在以前的研究中，一项重复性研究确立了可靠地测量导致运动员脚踝受伤的因素的能力。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名没有严重脚踝创伤病史、没有使用支架或绷带的大学前或大学阶段运动员将被前瞻性研究。这些人包括参加足球、曲棍球和曲棍球以及篮球和网球的男性和女性。评估将基于初步研究和其他研究提出的潜在危险因素、人口统计信息、形态测量、踝关节松弛、足部和脚踝的解剖对齐、等速踝关节力量、姿势稳定性以及对足部矢状面和额面扰动的肌肉反应时间。然后对每个运动员进行跟踪，以记录他们参加练习和比赛的情况。利用这些数据，一种或多种内在风险因素将被用来预测哪些人脚踝韧带创伤的风险增加，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.
