New treatment option for Spinal Cord Injuries
Official title Closed-Loop Deep Brain Stimulation for Refractory Chronic Pain
ClinicalTrials.gov ID: NCT04144972
What this study is testing
- What it's testing
- Chronic pain affects 1 in 4 US adults, and many cases are resistant to almost any treatment. Deep brain stimulation (DBS) holds promise as a new option for patients suffering from treatment-resistant chronic pain, but traditional approaches target only brain regions involved in one aspect of the pain experience and provide continuous 24/7 brain stimulation which may lose effect over time.
- This is a blinded study.

- History of substance abuse in past 3 years
- Inability to stop anticoagulation or platelet anti-aggregation therapy for surgery and recovery.
- Implantable hardware not compatible with MRI or with the study.
- MR abnormalities that suggest an alternative diagnosis or contraindicate surgery
