Sudomotor function refers to the autonomic nervous system control of sweat gland activity in response to various environmental and individual factors. Sweat production is a vital thermoregulatory mechanism used by the body to prevent heat-related illness as the evaporation of sweat is the body’s most effective method of heat reduction and the only cooling method available when the air ...
ESC is intended to provide insight into and assess sudomotor (or sweat gland) function and small fiber peripheral neuropathy. The measure was principally developed by Impeto Medical to diagnose cystic fibrosis from historical research at the Mayo Clinic and then tested on others diseases with peripheral neuropathic alterations in general.

Dysautonomia, autonomic failure, or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This condition may affect the functioning of the heart , bladder , intestines , sweat glands , pupils , and blood vessels.
Typical symptoms include gastrointestinal dysmotility, orthostatic hypotension, and tonic pupils. [1] Many cases have a sudden onset, but others worsen over time, resembling degenerative forms of autonomic dysfunction. For milder cases, supportive treatment is used to manage symptoms. [2]
Idiopathic pure sudomotor failure (IPSF) is the most common cause of a rare disorder known as acquired idiopathic generalized anhidrosis (AIGA), a clinical syndrome characterized by generalized decrease or absence of sweating without other autonomic and somatic nervous dysfunctions and without persistent organic cutaneous lesions.
Complex regional pain syndrome (CRPS type 1 and type 2), sometimes referred to by the hyponyms reflex sympathetic dystrophy (RSD) or reflex neurovascular dystrophy (RND), is a rare and severe form of neuroinflammatory and dysautonomic disorder causing chronic pain, neurovascular, and neuropathic symptoms.
The majority of symptoms that patients with PAF exhibit are associated with neurogenic orthostatic hypotension, or orthostatic hypotension brought on by severe sympathetic failure. Within three minutes of standing up straight, orthostatic hypotension is defined as a drop in systolic blood pressure of at least 20 mm Hg or a drop in diastolic ...
The neurotransmitters of postganglionic fibers differ: In the parasympathetic division , neurons are cholinergic . That is to say acetylcholine is the primary neurotransmitter responsible for the communication between neurons on the parasympathetic pathway .
