<unk>  (ESC) is an objective, non-invasive and quantitative electrophysiological measure. It is based on reverse iontophoresis and (multiple) steady chronoamperometry (more specifically chronovoltametry). ESC is intended to provide insight into and assess sudomotor (or sweat gland) function and small fiber peripheral neuropathy.
