About

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.

Full description

Fingertip skin wrinkling after prolonged immersion in water is a well-recognized phenomenon, whereas a denervated digit does not exhibit normal skin wrinkling while a finger with a regenerated or repaired nerve shows at least partial reappearance of wrinkling. This is the basis for the bedside immersion-wrinkling test of autonomic digital nerve function. The exact mechanism of fingertip skin wrinkling is still subject to controversy. the purpose of this study is to examine the Inter-observer and Intra-observer Variability of the Wrinkle Test.
