A survey conducted among 116 crew members of seagoing vessels confirmed that mal de debarquement (M-D) is a transient feeling of swinging, swaying, unsteadiness, and disequilibrium. None of the subjects requested medical attention, although there were isolated cases in which a strong sensation of swinging and unsteadiness caused transient postural instability and impaired the ability to drive. In most cases, the sensation of M-D appeared immediately on disembarking and generally lasted a few hours. In addition, subjects usually described bouts or attacks of M-D associated with changes in body posture, head position, or with closing of the eyes. M-D was reported by 72% of our subjects. Sixty-six percent of subjects reported a high incidence following their first voyages. A significant positive correlation was found between M-D and seasickness susceptibility. The nature of M-D may be explained within the framework of multisensorimotor adaptation and habituation to a new or abnormal motion environment. It is suggested that M-D represents a dynamic, multisensorimotor form of CNS adaptive plasticity.
一项针对116名海船船员开展的调查证实,下船后不适(M-D)是一种摇摆、晃动、不稳定和失衡的短暂感觉。尽管有个别案例中强烈的摇摆和不稳定感导致了短暂的姿势不稳并影响了驾驶能力,但没有受试者寻求医疗帮助。在大多数情况下,M-D的感觉在刚下船时就立即出现,通常持续几个小时。此外,受试者通常描述M-D的发作或发作与身体姿势、头部位置的变化或闭眼有关。72%的受试者报告有M-D。66%的受试者报告在首次航行后发病率很高。发现M-D与晕船易感性之间存在显著正相关。M-D的本质可以在多感觉运动适应和对新的或异常运动环境的习惯化框架内得到解释。有人提出,M-D代表了中枢神经系统适应性可塑性的一种动态、多感觉运动形式。
