Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
