Using infrared imaging to assess spinal cord stimulation effects in CRPS patients

The Effect of Spinal Cord Stimulation on Thermal Forward Looking InfraRed (FLIR) Imaging in Complex Regional Pain Syndrome (CRPS)

Observational Hospital for Special Surgery, New York · NCT05777889

This study is testing if infrared imaging can help track changes in pain and quality of life for people with Complex Regional Pain Syndrome after they receive spinal cord stimulation.

What this trial studies

This observational study aims to evaluate the effectiveness of Forward Looking InfraRed (FLIR) imaging in monitoring sympathetic activity in patients with Complex Regional Pain Syndrome (CRPS) before and after spinal cord stimulation (SCS). It will assess whether SCS enhances sympatholytic activity and how this correlates with various outcome measures, including pain levels and quality of life. Participants will have thermal images of their feet taken and will complete questionnaires regarding their symptoms and functional capacity. The study seeks to provide insights into the relationship between SCS and sympathetic dysfunction in CRPS patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 with CRPS who have not responded to conventional treatments and have significant pain levels.

Not a fit: Patients with other underlying conditions affecting sympathetic function or those with specific contraindications will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and treatment strategies for patients suffering from CRPS.

How similar studies have performed: While the use of FLIR imaging in this context is relatively novel, similar studies have shown promise in assessing sympathetic activity in other conditions.
