The development of prevention strategies is critical to address the rising prevalence of sport-related concussions. Visual and sensory performance may influence an individual's ability to interpret environmental cues, anticipate opponents' actions, and create appropriate motor responses limiting the severity of an impending head impact. The purpose of this study was to determine the relationship between traditional and visual sensory reaction time measures, and the association between visual and sensory performance and head impact severity in college football players. Thirty-eight collegiate football players participated in the study. We used real-time data collection instrumentation to record head impact biomechanics during games and practices. Our findings reveal no significant correlations between reaction time on traditional and visual sensory measures. We found a significant association between head impact severity and level of visual and sensory performance for multiple assessments, with low visual and sensory performers sustaining a higher number of severe head impacts. Our findings reveal a link between level of visual and sensory performance and head impact biomechanics. Future research will allow clinicians to have the most appropriate testing batteries to identify at-risk athletes and create interventions to decrease their risk of injurious head impacts.
预防策略的发展对于解决与运动相关的脑震荡的高发率至关重要。视觉和感官表现可能会影响个体解释环境线索、预测对手动作以及做出适当的运动反应的能力，从而限制即将发生的头部冲击的严重程度。本研究的目的是确定传统和视觉感官反应时间测量之间的关系，以及视觉和感官表现与大学橄榄球运动员头部冲击严重程度之间的关联。38 名大学生橄榄球运动员参加了这项研究。我们使用实时数据采集仪器在比赛和训练中记录头部冲击生物力学。我们的研究结果表明，传统和视觉感官测量的反应时间之间没有显著相关性。我们发现，头部冲击严重程度与视觉和感官表现水平之间存在显著关联，对于多项评估，视觉和感官表现水平较低的运动员承受的严重头部冲击次数更多。我们的研究结果揭示了视觉和感官表现水平与头部冲击生物力学之间的联系。未来的研究将使临床医生能够拥有最合适的测试组合，以识别有风险的运动员，并制定干预措施降低他们遭受有害头部冲击的风险。
