QDIRT: quantitative direct and indirect test of sudomotor function.

ABSTRACT:

Objective

To develop a novel assessment of sudomotor function.

Background

Postganglionic sudomotor function is currently evaluated using the quantitative sudomotor axon reflex test (QSART) or silicone impressions. We hypothesize that high-resolution digital photography has advanced sufficiently to allow quantitative direct and indirect reflex testing of sudomotor function (QDIRT) with spatial and temporal resolution comparable to these techniques.

Methods

Sweating in 10 humans was stimulated on both forearms by iontophoresis of 10% acetylcholine. Silicone impressions were made and topical indicator dyes were digitally photographed every 15 seconds for 7 minutes after iontophoresis. Sweat droplets were quantified by size, location, and percent surface area. Each test w
