Abstract
Neurophysiologic testing is not routinely used to assess anorectal disorders. However, it can be useful in at least two instances, the first of which is to assess anorectal disorders in patients with central and peripheral neurologic diseases (e.g., trauma, multiple sclerosis, Parkinson’s, diabetes, etc.). Anorectal disorders (incontinence and/or constipation) may be the initial symptom of these pathologies (Bardoux et al. 1997; Abbott et al. 2001) or may even be neurologic in origin. Information provided by neurophysiologic testing may help to determine the prognosis of the disease, and thus the treatment and therapeutic follow-up (Lefaucheur 2006). Secondly, in patients with a known neurologic disease, neurophysiologic testing can be used to discriminate between a bowel dysfunction and a neurologic disease since anorectal disorders in such patients are not necessarily due to a neurologic pathology, but may arise from other pathologies such as an anatomical trauma or a dynamic pelvic floor disorder. The exact mechanism of anorectal disorders in these neurologic patients will inform the therapeutic approach.
