Abstract:
Objective To evaluate the function of afferent neuronal pathways (ANP) from the lower urinary tract (LUT) in patients with spinal cord injury (SCI) by use of sympathetic skin response (SSR). Methods Twenty-one patients with SCI (13 cases of incomplete injury, and 8 cases of complete injury) were recruited as a SIC group and 8 healthy volunteers as a control group. SSRs of all subjects were evoked by means of electrical stimulation (ES) of the median nerve and perineal region,as well as bladder filling (BF), while SSRs of the right palm and sole were recorded using surface electrodes. Results SSRs induced by ES of the median nerve and perineal region, and also by BF in the control group were recorded. SSRs of palms and soles could be recorded by using ES of the median nerve in patients with incomplete SCI, who had desire to void. However, SSRs could not be evoked in 3 of 13 patients with incomplete SCI but without sensation of perineal skin. In 8 patients with complete SCI but without sensation of trunk skin and bladder, SSRs of palms and soles could not be induced during ES of the median nerve if injuries were located over T_3, and SSRs of palms were recorded when the injuries were located between T_(4~9), while SSRs of palms and soles were evoked if injuries were located under T_(10). However, SSRs of palms and soles could not be evoked by ES of perineal region and BF in all patients. Conclusion SSRs, evoked by BF, could concord with the subjective sensation of the subjects from the LUT, and reflect the integrity of ANP from LUT. There is difference between somatosensory and viscerosensory ANP.
