Sudomotor Testing


  • Analyze and test responsiveness and accuracy in detecting diabetic neuropathy and compare it with existing standardized tests for the diagnosis of diabetic neuropathy.

  • Evaluate in patients with Diabetes Mellitus, as an instrument to assess autonomic neuropathy and neuropathic pain.

  • Sudomotor Testing is an innovative, sensitive tool for the detection of diabetic neuropathy, especially painful diabetic neuropathy. As sweat glands are innervated by small c fibers, which are also involved in pain pathways, precise measuring of the sweat gland function can identify that cause.

  • A sensitive device to detect neuropathy in patients with diabetes mellitus.

  • When compared to non-painful neuropathy, feet BEC was significantly decreased in patients with painful diabetic neuropathy.

  • These results suggest that the peripheral autonomic nervous system plays a role in painful diabetic neuropathy.

  • Results correlated significantly with clinical neuropathy scores, pain scores and measures of autonomic dysfunction.


  • Fully interpreted report generated from the software, immediately following assessment.

  • Color-coded, alphabetically graded biomarkers that provide quantitative tracking that is easy to see.

  • Report structure designed to provide an initial summary with a variety of in-depth options to save or print for easy EMR upload.


  • Small unmyelinated C-fibers are responsible for the function of sweat glands

  • Sudomotor dysfunction has been established as one of the earliest detectable neurophysiologic abnormalities in distal small fiber neuropathies.

  • As an index of the severity and distribution of automatic failure, quantitative assessment of sweat response has been proposed. It will also serve as an early indicator for the regeneration of small fibers.

  • Diabetic patients have been observed to experience a degeneration of small C-fiber innervating sweat glands

  • Measures bio electrochemical sweat skin conductances (BEC), which are directly connected to the capability of the glands to transfer chloride ions and which reflects small-C fiber status.

  • Is a fast and easy method to measure sweat function
