Study Summary
The study will investigate the application of a non-pharmacological operant conditioning approach to reduce phantom limb pain (PLP). PLP afflicts 60-90% people who have lost a limb. It can last for years and lead to drug dependence, job loss, and poor quality of life. Current non-pharmacological interventions are encouraging but limited, and their efficacy remains unclear. Limb amputation is known to lead to abnormal sensorimotor reorganization in the brain. Multiple studies have shown that PLP severity is correlated with the extent of this reorganization. The current study will train participants via realtime feedback of brain responses to promote more normal sensorimotor response, with the goal to reduce phantom limb pain.
Primary Outcome
The Sf-MPQ assesses the pain quality in the sensory (11 items) and affective (4 items) dimensions. Each item is rated on an intensity scale of 0 (none) to 3 (severe). Total score is obtained by summing the scores for all items and the range is 0 (no pain) to 45 (severe pain).
Interventions
- BEHAVIORAL Operant Conditioning with Peripheral Stimulation
- BEHAVIORAL Control Group with Peripheral Stimulation Only
