In a 1972 study of 250 MS patients, McAlpine's researchers found that 14 percent had an injury within three months prior to onset. In a parallel study of 250 patients with other diseases, only 5.4 percent had an injury within three months prior to onset. Although the studies showed a significant difference, most authorities do not believe that injury actually causes MS. It is more likely that injury brings out symptoms of an existing lesion that was previously silent.
