title: Bulbocavernosus reflex and pudendal nerve somatosensory-evoked potentials responses in female patients with nerve system diseases.
abstract: To assess the value of bulbocavernosus reflex (BCR) and pudendal nerve somatosensory-evoked potential (SSEP) in the topical diagnosis of central and peripheral nervous system diseases in female patients. Neuroelectrophysiologic technique was adopted to determine both BCR and SSEP of 41 healthy adult females (control group), 30 female patients with spinal cord lesions (central group), and 50 female patients with peripheral nerve lesions (peripheral group), including nine female patients with acute cauda equina syndrome. The abnormality rates of BCR were 8.33% and 70.00% in the central group and the peripheral group, respectively, and there were statistical differences between the two groups. The abnormality rates of BCR were 72.22% in the patients with acute cauda equina syndrome abnormal, who have at least one side of the abnormal BCR. The abnormality rates of SSEP P41 were 86.67% and 82.00% in the control and peripheral groups, respectively, and there were no statistical differences between the two groups. The abnormality rates of SSEP P41 were 88.89% in the patients with acute cauda equina syndrome abnormal. Also, there were no statistical differences between the peripheral group and the patients with acute cauda equina syndrome in the abnormality rates of SSEP or BCR. Both BCR and SSEP changed in the peripheral group, especially in the patients with acute cauda equina syndrome, but only SSEP changed in the central group. BCR and SSEP are valuable in the topical diagnosis of nervous system diseases in females.
