Though the SBS hypothesis was incorporated into medical training and judicial decisions worldwide, it remained untested for almost two decades. In 1987, the first biomechanical experiments found that the force of shaking is much less than that of impact and concluded that shaking alone was unlikely to cause the triad of symptoms.
尽管SBS假说已在全世界范围被纳入医学训练和司法判决，但在近20年的时间里，它并没有经受过测试。1987年，第一次生物力学实验发现，震动力远远小于撞击力，因此仅凭震动不可能造成三重症候。
