Quantitative Sudomotor Axon Reflex Test (QSART)

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

The Quantitative Sudomotor Axon Reflex Test is a quantitative test of postganglionic sudomotor function. The neural pathway is nicotinic and the sweat gland receptor is muscarinic. Stimulus consists of iontophoresed acetylcholine and evoked sweat volume is quantitated. The test is sensitive and reproducible in detecting denervation. Recording sites are over the arm and leg. There is extensive experience with the test in diabetic and other autonomic neuropathies, and in clinical trials.
