Abstract

The main purpose of this article is to determine a method of supporting the sympathetic skin response (SSR) as a sensitive clinical test. Using a non-invasive technique the SSRs are simultaneously recorded by 4 channel EMG machine. Thirty adults (10 women and 20 men, aged 19 to 46 years), normal and healthy, participated in this experiment. Not only did the latencies recorded on both palms respond faster than those on both soles, but the amplitudes measured on the palms were also higher. From these observations, one is bound to conclude that the SSR is not a segmental response but a long systemic response. More than two channel EMG recordings are desirable to see whether or not there is a lesion in any part of the SSR's pathway. Comparing the SSRs made both on the palms and soles simultaneously is recommendable in order to increase the its sensitivity.
