To assess whether concussion history adversely affects multisensory integration, we compared susceptibility to the Sound-Induced Flash Illusion (SIFI) in retired professional rugby players compared to controls.
Retired professional rugby players ((N = 58) and retired international rowers (N = 26) completed a self-report concussion history questionnaire and the SIFI task. Susceptibility to the SIFI (i.e., perceiving two flashes in response to one flash paired with two beeps) was assessed at three stimulus onset asynchronies (70 ms, 150 ms or 230 ms).Logistic mixed-effects regression modeling was implemented to evaluate how athlete grouping, previous concussion history and total number of years playing sport, impacted the susceptibility to the SIFI task. The statistical significance of a fixed effect of interest was determined by a likelihood ratio test.
Former rugby players had significantly more self-reported concussions than the rower group (p < 0.001). There was no impact of athlete grouping (i.e., retired professional rugby players and retired international rowers), years participation in elite sport or concussion history on performance in the SIFI.
A career in professional rugby, concussion history or number of years participating in professional rugby was not found to be predictive of performance on the SIFI task.
为了评估脑震荡史是否会对多感觉整合产生不利影响，我们比较了退役职业橄榄球运动员和对照组对声音诱导闪光错觉（SIFI）的易感性。
退役职业橄榄球运动员（N=58）和退役国际赛艇运动员（N=26）完成了一份自我报告的脑震荡史问卷和 SIFI 任务。在三个刺激起始时间间隔（70 ms、150 ms 或 230 ms）下评估对 SIFI（即对一个闪光和两个哔哔声配对的两个闪光的感知）的易感性。实施逻辑混合效应回归模型，以评估运动员分组、以前的脑震荡史和运动总年限如何影响 SIFI 任务的易感性。感兴趣的固定效应的统计学显著性通过似然比检验确定。
前橄榄球运动员自我报告的脑震荡次数明显多于赛艇运动员组（p<0.001）。运动员分组（即退役职业橄榄球运动员和退役国际赛艇运动员）、参与精英运动的年限或脑震荡史对 SIFI 表现均无影响。
在 SIFI 任务上的表现不受职业橄榄球生涯、脑震荡史或参与职业橄榄球年限的影响。
