Autonomic Dysfunction and Spinal Cord Stimulation in Complex Regional Pain Syndrome (CRPS)
Autonomic Dysfunction and Spinal Cord Stimulator in Complex Regional Pain Syndrome
To demonstrate that spinal cord stimulator has an effect on sympathetic function (the one that give us the fight and flight response). Therefore, if the spinal cord stimulator has an effect on sympathetic function, the responses from CRPS patients to different stimuli will differ significantly pre and post SCS implant.
If CRPS patients exhibit autonomic, CRPS patients could be stratified according to their sympathetic function pre-implant. It is expected that patients with a moderate/mild form of autonomic dysfunction will have better outcomes with the SCS.

PLACEBO_COMPARATOR: CRPS patients without spinal cord stimulation
CRPS patients declining spinal cord stimulation therapy.
Autonomic Function will be assessed at baseline and again within 2 years.

EXPERIMENTAL: CRPS patients: candidates for spinal cord stimulator
CRPS patients who are candidates for spinal cord stimulator implant.
These patients will have Autonomic Function assessments before and after the Standard of Care spinal cord stimulation implant
