Skin wrinkling on immersion of hands: a test of sympathetic function

J Braham et al. Arch Neurol. 1979 Feb.

Abstract

Skin wrinkling of the fingers following immersion in warm water depends on intact sympathetic innervation. It is abolished by lesions affecting both central and peripheral sympathetic pathways. It affords a simple and reliable clinical test of sympathetic function.
