Study Summary
Duloxetine has recently been shown to be effective in reducing the pain in chronic pain patients. Duloxetine is known to exert a central mechanism, however the precise human brain structures responsible for mediating its pain-relieving properties are not known. We will use functional magnetic resonance imaging (FMRI) to investigate the neural and functional correlates of pain.
Primary Outcome
Brief Pain Inventory (BPI) scores were obtained at baseline, weeks 1, 2, 6, 7, 8, and 12, and a follow-up visit one week after completing the study. Responses are rated on a scale from 0-10, with 0 = no pain and 10 = pain as bad as you can imagine. Placebo and duloxetine pain scores calculated by averaging pain scores from each visit after baseline. Values were converted to percent change in pain: \[(baseline pain - end point pain)/baseline pain\] x 100.
Interventions
- DRUG Placebo
- DRUG duloxetine
