Relationship of Q-sweat to quantitative sudomotor axon reflex test (QSART) volumes.

ABSTRACT: Q-Sweat, a commercial quantitative sweat measurement system, is modeled on quantitative sudomotor axon reflex testing (QSART). This study investigated the sweat response using Q-Sweat and Mayo-QSART recordings under identical conditions in healthy normal controls. Ninety-four participants were recruited for this study. All participants underwent randomized bilateral QSART recordings over the four standard recording regions. For both men and women, Wilcoxon signed rank tests of paired differences showed significantly lower volumes at each of the four sites for Q-Sweat vs. Mayo-QSART. Linear regression analysis was used to estimate the relationship between Q-Sweat and Mayo-QSART volume measurements separately for men and women. Although there was variability about the regression lines, these
