Evaluation of the finger wrinkling test: a pilot study.

Purpose: Tilt table testing mainly evaluates the systemic cardiovascular part of the autonomic nervous system, while it is assumed that the finger wrinkling test assesses the peripheral part of the autonomic nervous system. In this study we explored whether the finger wrinkling test could be a useful test for autonomic dysfunction and whether the clinical evaluation of wrinkling can be improved by digital analysis of photographs.

Methods: As much as 20 healthy subjects and 15 patients underwent tilt table testing and finger wrinkling testing.
