The purpose of the present study was to reveal possible neurological sequelae of amateur boxing after the introduction of modern medical supervision and safety precautions. Neurological, electroencephalographic and neuropsychological examinations were performed in a total of 53 former champion amateur boxers together with a control group consisting of 53 former football players. The football players were, on an average, better educated than the boxers, but otherwise the two groups were comparable. Complaints, neurological findings and electroencephalographic changes were identical in the boxers and control group. Only minor neuropsychological disturbances were found in the boxers most pronounced in impaired motor function of the left hand. This was further demonstrated by comparing 19 pairs, each consisting of one boxer and one football player, matched according to age, education and vocabulary. No relation between abnormal findings and "occupational exposure" during the boxing career could be demonstrated, not even by comparing three pairs of identical twins, although in each twin of the pairs there was a great difference in the number of fights. This study provides no basis for legislation against amateur boxing at the present time, as it indicates that the existing safety precautions protect the boxers against serious and permanent brain damage.
本研究的目的是揭示在引入现代医学监督和安全预防措施后，业余拳击可能产生的神经后遗症。对53名前业余拳击冠军以及由53名前足球运动员组成的对照组进行了神经学、脑电图和神经心理学检查。足球运动员平均受教育程度高于拳击手，但除此之外两组具有可比性。拳击手组和对照组的主诉、神经学检查结果和脑电图变化相同。在拳击手中仅发现轻微的神经心理学障碍，最明显的是左手运动功能受损。通过比较19对年龄、教育程度和词汇量相匹配的个体（每对包括一名拳击手和一名足球运动员），进一步证明了这一点。即使比较三对同卵双胞胎，也无法证明拳击生涯中的异常发现与“职业暴露”之间存在关联，尽管每对双胞胎中两人的比赛次数差异很大。这项研究目前没有为禁止业余拳击的立法提供依据，因为它表明现有的安全预防措施可保护拳击手免受严重和永久性脑损伤。
