title: Sympathetic skin response. Glabella stimulation may be more useful than peripheral nerve stimulation in clinical practice.
abstract: The aim is to verify whether glabella electrical stimulation evokes sympathetic skin responses (SSR) without inter-side differences in latency and area of the responses and is more useful in mononeuropathies than peripheral nerve stimulation. SSRs were recorded in 25 healthy subjects from right palm, third (M3SSR) and fifth fingers and contralateral third finger. The inter-side differences of grand mean area and mean of largest area of M3SSR were significant only by ulnar nerve and not by glabella stimulation. Therefore glabella stimulation may be used in mononeuropathies comparing SSR area recorded from affected side with respect to contralateral healthy side.
