[Physical trauma and multiple sclerosis].

Without a more detailed knowledge of etiology and pathogenesis of multiple sclerosis final conclusions regarding an association between physical trauma and the onset or course of multiple sclerosis cannot be drawn. Only a few prospective studies which are appropriately designed to prove a putative correlation have been published. A critical review of these studies and some case reports, in the light of the current pathophysiological concepts of multiple sclerosis, does not indicate a causal relationship between physical trauma and onset of multiple sclerosis or exacerbations.
