Clinical Neurophysiology of the Pelvic Floor

  • Chapter
Pelvic Floor Disorders

Abstract

Electrodiagnostic testing of the pelvic floor is becoming increasingly common in clinical pelvic medicine and pelvic floor research. Clinically, it can be used with history, physical examination, and urodynamic testing to aid in the diagnosis of certain pelvic floor disorders and to determine if a central or peripheral neurologic problems exists. Electrodiagnostic testing is also emerging in studies investigating the etiology of pelvic floor disorders. A basic understanding of the principles and techniques used in electrodiagnostic medicine is essential for reconstructive pelvic surgeons. However, most pelvic surgeons will never have the skills or expertise to perform pelvic floor neurophysiologic testing. Multidisciplinary teams including urogynecologic, urologic, and colorectal surgeons, physiatrists, neurologists, and physical therapists are imperative if we are going to improve our understanding of pelvic floor disorders and improve treatment outcomes.
