SUDOSCAN : An innovative device for early detection and follow-up of Autonomic and Small Fiber Neuropathy.

About Sudoscan

SUDOSCAN offers a stimulation of the sweat glands that assess small nerve fibers

Picto-diabetology

Diabetes

SUDOSCAN provides a better management of diabetes complications such as neuropathies to prevent diabetic foot.

Picto-Neurology

Neurology

SUDOSCAN has demonstrated its efficacy in painful neuropathies, transthyretin amyloidosis, Sjogren’s Syndrome, Hepatitis C, Fabry disease….

Picto-Oncology

Oncology

In oncology, SUDOSCAN has demonstrated its utility to quantify chemotherapy induced polyneuropathy (CIPN).

Picto-Follow-up

Follow-up

SUDOSCAN allows the physician to follow patient outcomes over time and assess the progression of neuropathy and the impact of medications.

An innovative device

SUDOSCAN is a test that provides an accurate evaluation of sweat function. The test focuses on small nerve fibers within the peripheral nervous system innervating the sweat glands.

The device consists of a computer and 4 electrodes on which patients place their hands and bare feet. In less than 3 minutes, SUDOSCAN offers a stimulation of the sweat glands that assess small nerve fibers (C fibers).

Simple results obtained in 3 minutes

The results are displayed automatically.
If the score is high, this indicates no sign of sudomotor dysfunction and no autonomic neuropathy. If the score is low, this indicates a sudomotor dysfunction and a neuropathy.

Sudoscan Technology

BY IMPETO MEDICAL

SUDOSCAN tests sweat gland function by applying a small direct current to both hand and foot sensor plates. At a low voltage, the stratum corneum acts as a capacitor, leaving the sweat ducts as the only channel for the transmission of Cl- ions.
SUDOSCAN provides a quantitative measure of chloride conductance (measured in microsiemens) and its results serve as a biomarker to assess sweat gland function in relation to sweat gland innervation.

The process

  • The patient is asked to put his hands and feet on large electrodes
  • A small electric tension is applied to the surface to stimulate the sweat glands
  • The results of the response to this stimulation are expressed as :
    1. Electrochemical Skin Conductance for SUDOSCAN, indicating the presence and severity of the small fiber peripheral autonomic neuropathies;
    2. Percentage of risk for EZSCAN indicating a risk to develop diabetes.
