Why the study?
Does the sympathetic skin response (SSR) correlate with the quantitative sudomotor axon reflex test (Q-SART) and cardiac beat-to-beat variability in patients with diabetic neuropathy?
Population
39 patients with diabetic neuropathy, of whom 33 had one or more symptoms of autonomic involvement
Design
Cross-sectional

Concordance supports combined SSR and Q-SART for sympathetic assessment in diabetic neuropathy; hypothesis-generating and requires prospective validation.
Does the sympathetic skin response (SSR) correlate with the quantitative sudomotor axon reflex test (Q-SART) and cardiac beat-to-beat variability in patients with diabetic neuropathy?
The concordance between sympathetic skin response and quantitative sudomotor axon reflex test supports their combined use to detect early distal sympathetic failure in diabetic neuropathy.
Maselli et al. (1989) studied this question.
