| Abstract: | The diagnostic role of electromyography of external urinary sphincter is well established in neurologically compromised patients. A brief historical review and methodology is described. For those who are not familiar with this modality, the character and clinical significance of abnormal potentials has been described. The coordination of bladder and sphincter mechanism and its abnormality is explained. Our experience with various neurological disorders is listed. It includes myelodysplasia, transverse myelitis, multiple sclerosis, herpes zoster, Parkinson disease, and some cerebral disorders. Any apparent statistical difference is due to the highly selected nature of the cases. |
