SSR is a noninvasive biomarker of sympathetic cholinergic sudomotor
function associated with autonomic dysfunction.
Lack of access to specialized sudomotor
or sensory testing precluded their use.
In the period after the headache, the sudomotor
hyper-function is more dominant on the symptomatic side.

CRPS type I is indicated by pathological sensory, motor, sudomotor
, vasomotor, and/or trophic changes, most commonly localized to the distal part of the extremities (1,3).
The syndrome is characterized with regional pain and vasomotor, sudomotor
and sensory changes in the distal parts of the extremities involved.
With autonomic neuropathy there can also occur trophic changes which includes dry skin, callouses in pressure areas and abnormal hair and nail growth and sudomotor
changes involving swollen feet with increased or decreased sweating.
Vasodilation response and sudomotor
response release heat from the body and keep the core temperature from rising further.
However, the simple method of sweat collection requires a significant sweat volume for analysis and thus may not prove appropriate for SCI subjects with altered or reduced sudomotor
Aim: Complex regional pain syndrome (CRPS) is characterized by pain, vasomotor and sudomotor
changes and trophic disturbances.
