Water Immersion-Induced Skin Wrinkling: More Accurately Reflects Neurovascular Coupling rather than Just Neural Function
Received Date: December 11, 2019; Published Date: December 17, 2019
Skin wrinkling (SW) is a normal response to water immersion (WI) that is impaired after peripheral nerve injury. The mechanism appears to involve passive diffusion of water across the stratum corneum into the sweat ducts. This alters electrolyte balance and increases sympathetic neural firing causing vasoconstriction. SW results from a decreased digital volume relative to surface area. WISW has been suggested to be a measure of peripheral sympathetic function, to reflect autonomic function and small fibre neural function. Since this response involves both neural and vascular responses, we propose WISW to more accurately reflect neurovascular coupling.
