Sudoscan in the world

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


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


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


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


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


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.

The advantage of
Neuropathy Early Detection

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

Simple results obtained in 3 minutes.

The Process

The results are displayed automatically.

  • 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:

    • Electrochemical Skin Conductance for SUDOSCAN, indicating the presence and severity of the small fiber peripheral autonomic neuropathies.
