在大学和职业橄榄球生涯中持续的脑震荡与急性和慢性神经损伤都有关。亚震荡冲击对这种损伤的贡献还没有得到充分的研究。因此，我们在神经功能的临床测量中调查了亚震荡撞击与脑震荡病史之间的关系。46名大学生足球运动员在一个赛季前后完成了五项神经功能的临床测量，通常用于脑震荡的评估。这些测试包括自动神经心理评估量表、感觉组织测试、震荡标准化评估、平衡错误评分系统和分级症状检查表。头部撞击遥测(HIT)系统记录了头部撞击数据，包括撞击的频率、幅度和位置。大学橄榄球运动员在一个赛季中遭受了大约1000次脑震荡对头部的冲击，但在大多数情况下，从季前赛到季后赛，在神经功能指标上没有表现出任何有临床意义的变化。表现的变化大多与既往脑震荡病史无关，观察到的R-2值在一个赛季中持续撞击的总数、幅度和位置在0.30到0.35之间。在一个赛季中重复的亚震荡头部撞击似乎不会导致短期的神经损伤，但这些关系应该进一步研究球员职业生涯中潜在的剂量反应。
Concussions sustained during college and professional football careers have been associated with both acute and chronic neurologic impairment. The contribution of subconcussive impacts to this impairment has not been adequately studied. Therefore, we investigated the relationship between subconcussive impacts and concussion history on clinical measures of neurologic function. Forty-six collegiate football players completed five clinical measures of neurologic function commonly employed in the evaluation of concussion before and after a single season. These tests included the Automated Neuropsychological Assessment Metrics, Sensory Organization Test, Standardized Assessment of Concussion, Balance Error Scoring System, and Graded Symptom Checklist. The Head Impact Telemetry (HIT) System recorded head impact data including the frequency, magnitude, and location of impacts. College football players sustain approximately 1,000 subconcussive impacts to the head over the course of a season, but for the most part, do not demonstrate any clinically meaningful changes from preseason to postseason on measures of neurologic function. Changes in performance were mostly independent of prior concussion history, and the total number, magnitude and location of sustained impacts over one season as observed R-2 values ranged between 0.30 and 0.35. Repetitive subconcussive head impacts over a single season do not appear to result in short-term neurologic impairment, but these relationships should be further investigated for a potential dose-response over a player's career.
