Effectiveness and usability of the HALO compression shirt

加拿大医院每年诊断出大约10万例脑震荡，其中大约三分之二**与运动有关。预防脑震荡是加拿大人关注的主要问题，各种运动器材制造商都在关注这一问题。加拿大设计和技术公司Aexos Inc.（滑铁卢，安大略省**加拿大）开发了一种压缩衬衫，旨在减少在接触性运动中头部和颈部的撞击。该技术的有效性已通过计算机建模和实验室测试进行了评估。然而，其有效性尚未在运动员的运动环境中进行评估。此外，很少有研究评估该设备的可用性。这家公司有兴趣研究他们的技术在身体接触运动中减弱头部加速度的有效性，并评估其可用性。在过去的5年里，我们一直在进行研究，评估大学橄榄球运动员头部撞击的程度，以及它们对神经系统的影响。我们建议通过比较佩戴HALO**技术的球员头部撞击的大小与球员未佩戴HALO**技术时匹配撞击的历史数据来评估HALO**技术的有效性。具体来说，佩戴HALO技术的球员所产生的影响将根据球员的位置和比赛风格（进攻、防守、跑动、传球、回球等）与我们过去5年收集的超过10万次撞击进行匹配。此外，我们将调查玩家，以获得有关技术可用性的信息。

Approximately 100,000 concussions are diagnosed each year in Canadian hospitals,and approximately two-thirds**are sports related. Prevention of concussions is a major focus for Canadians, and has been taken up by a variety**of sports equipment manufacturers. A Canadian design and technology company, Aexos Inc. (Waterloo, Ontario**Canada), has developed a compression shirt designed to reduce whiplash of the head and neck during impacts in**contact sports. The effectiveness of this technology has been assessed through computer modelling, and**laboratory testing. However, its effectiveness has not been assessed in sports environments with athletes.**Furthermore, there has been little research evaluating the usability of this equipment. This company is interested**in researching the effectiveness of their technology in attenuating the magnitude of head accelerations during**contact sports, and evaluating its usability. We have been performing research evaluating the magnitude of head**impacts in varsity football, and their neurological consequences, for the past 5 years. We propose to evaluate the**effectiveness of the HALO technology by comparing the magnitude of the head impacts from players wearing the**HALO technology compared to historical data of matched impacts when the players were not wearing HALO**technology. In specific, impacts from players wearing the HALO technology will be matched based on player**position and style of play (offense, defense, running, passing, kick return etc) to our library of more than 100,000**impacts collected over the past 5 years. In addition, we will survey the players to garner information about the**usability of the technology.
