SUDOSCAN® & Small Fiber Neuropathy

Peripheral neuropathy is the result of damage to peripheral nerves, including small fiber neuropathy involving small and myelinating nerves, as well as unmyelinated nerves (unmyelinated C fibers). In peripheral neuropathy, small somatic and autonomic fibers can be affected.

Small fibers control thermal perception, pain perception, and autonomic functions such as cardiac, pulmonary or enteric functions.

Peripheral neuropathy can be a complication of several diseases such as diabetes, neurological or metabolic disorders, and infections. It can also result from certain drugs or alcohol consumption.

Small fiber neuropathy can occur in the very early stages of the disease. Its detection may help physicians to better manage their patients and avoid advanced complications. Physicians can assess their patients for small fiber neuropathy by using a device called SUDOSCAN®.

SUDOSCAN® offers a stimulation of the sweat glands in the hands & feet that assess small nerve fibers. SUDOSCAN® is a test that provides an accurate evaluation of sweat function. The test focused 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.
