WebThe Quantitative Sudomotor Axon Reflex Test (QSART) measures the autonomic nerves that control sweating. This test utilizes a method to stimulate sweat glands and measure the volume of sweat that is produced. WebTypically, the distal ends of the longest nerve fibers are first affected in the axonal neuropathies. Small nerve fibers are often selectively involved and these are termed distal small-fiber neuropathy (DSFN). One method of recording C-fiber function is to study the function of the postganglionic sympathetic sudomotor “C”-fiber function (Low et al. 1983; …
