Infrared Images for Spinal Cord Stimulation in Complex Regional Pain Syndrome Patients

Description

The goal of this observational study is to compare thermal camera Forward Looking InfraRed (FLIR) images before and after spinal cord stimulation to evaluate the difference in sympathetic activity of the affected limb in patients with complex regional pain syndrome (CRPS). The main questions it aims to answer are: Question 1: Can Infrared (FLIR) imaging be used to monitor the sympatholytic activity caused by Spinal Cord Stimulation (SCS) in patients with CRPS? Question 2: Is there any correlation between the quantification of sympatholytic activity produced by Spinal Cord Stimulation (SCS) and measured by FLIR imaging with the outcome measures in patients with CRPS? Outcome measures include pain (NRS), CRPS Severity Score (CSS), Quality of Life (SF-36), and neuropathic pain score (painDETECT). Participants will have an image of their feet taken perpendicularly with a 1-inch space from all four sides using a FLIR T420 or T62101 camera with 320\*240 resolution. Participants will also complete questionnaires about the average pain, CRPS severity, quality of life, and neuropathic pain.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * The patient is between 18 and 85 years old
  • * Providing CRPS diagnostic criteria by using the Budapest Clinical Diagnostic Criteria.
  • * The patient has had pain and other symptoms for more than 3 months
  • * Not responding to conventional medical treatments and multidisciplinary approach
  • * High NRS detection in pain assessment despite appropriate treatment (NRS= and \> 6/10).
  • * Pain causing a limitation in the patient's functional capacity despite appropriate treatment.
  • * Patients with suspected disc herniation, spinal stenosis, myelopathy, and suspected radiculopathy in detailed examinations and examinations (MRI, CT).
  • * Systemic or local infection
  • * Coagulation disorders
  • * History of allergy to contrast material
  • * Malignancy
  • * Pregnancy
  • * Uncontrollable medical and psychiatric condition
  • * The patients diagnosed with dysautonomia, sympathetic dysfunction other than CRPS (such as Raynaud disease or Buerger disease), sweating disorders other than CRPS (such as acquired idiopathic generalized anhidrosis), and patients
