Neurofeedback Treatment of Pain in Persons With Spinal Cord Injury (SCI)

Completed

• Conditions: Spinal Cord Injury; Pain

• Registration Number: NCT00947999
• Lead Sponsor: University of Washington

Brief Summary

There has been little research on how chronic pain is related to brain activity. The purpose of this study is to learn more about pain and brain activity by finding any differences in brain activity among people who have moderate to severe chronic pain and a spinal cord injury, those who have a spinal cord injury but do not experience chronic pain, and people who have neither a spinal cord injury nor chronic pain (please note: subjects do not have to have pain to participate in this study). The information we collect will help the investigators get a better understanding of chronic pain.

Detailed Description

Research staff will record the brain activity of subjects by using an electroencephalogram (EEG), a device that measures the electrical activity in the brain through electrodes put on the scalp. There is no risk of electrical shock. Research staff will put a cap on the subject's head that has electrodes that will measure your brain activity. In addition to the electrodes in the cap, two electrode clips will be put on your ears. EEG activity will be collected for 20 minutes: subjects will have their eyes open for ten minutes, and then eyes closed for ten minutes.

Before the assessment, subjects will be asked how much pain they are currently in. Once the 20-minute assessment has ended, the research staff member will again ask subjects how much pain they are currently in, and how much pain they had during the EEG assessment. Subjects with SCI-related pain on a daily basis may also be contacted in the future to see if they want to participate in the second phase of this study that will involve learning to directly change their brain activity.
