Conditions

Complex Regional Pain Syndrome posttraumatic dystrophy

Interventions

Different frequencies of stimulation with a DRG Stimulator.

Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: - Patients diagnosed with CRPS according to the new IASP criteria - Patients must have vasomotor disturbance; the skin temperature of the affected extremity is at least 1°C colder than skin temperature of the contralateral extremity. This will be measured using a thermography imaging camera and determined using MatLab - Patients must have a DRG stimulator for treatment of CRPS, that has been implanted at least three months before inclusion - Clinically the contralateral extremity must be without signs or symptoms in a way that it can be used as a control.
