In cases of questionable insurance fraud through self mutilation axe blows now as before play an important role. Occasionally it is alleged that the billet began to totter during the stroke and that the left hand responded to this stimulus by an unwilled movement to the billet. By this the thumb or forefinger was placed unfortunately on the upper surface of the timber and hit by the chopper. According to the literature and on the basis of own experiments we estimate the reaction time, i.e. initiation time plus movement time, at 700 msec., at least, whereas the stroke needs only 220-290 msec. (chopper), and 280-380 msec. (axe), respectively, as could be shown in further experiments. That means, that the left hand can only touch the billet when the blow already has reached the goal. Hence unwilling finger mutilations can scarcely be the result of a "reflex action" of this kind.
在通过自残进行可疑保险欺诈的案例中，如今斧头砍击和以往一样起着重要作用。偶尔有人声称，在砍击过程中木块开始晃动，左手对这种刺激做出了不由自主的向木块移动的反应。结果不幸的是，拇指或食指被放在了木材的上表面并被斧头砍到。根据文献以及我们自己的实验，我们估计反应时间，即启动时间加上移动时间，至少为700毫秒，而砍击分别仅需220 - 290毫秒（斧头）和280 - 380毫秒（斧子），这在进一步的实验中得到了证实。这意味着，当砍击已经命中目标时，左手才可能碰到木块。因此，这种不情愿的手指致残几乎不可能是这种“反射动作”的结果。
