Peripheral Autonomic Neuropathy
When a stimulus causes backward nerve transmission, vasodilation of the innervated blood vessels occurs; this is the axon reflex, also referred to as the flare response. An impaired axon reflex indicates peripheral neuropathy. In practical terms, when skin is heated (by using the moorVMS-HEAT) or iontophoresed (by using the moorVMS-ION) with acetylcholine over a well defined area, microvascular blood flow also increases in the surrounding skin (as well as at the site stimulated). Laser Doppler monitoring (moorVMS-LDF) is used to assess the magnitude and time course of the vasodilation, and additional information on the flare area can be obtained with laser Doppler (moorLDI2) and Speckle imaging (moorFLPI-2).
