Home-based Rehabilitation Intervention for Phantom Limb Pain in Veterans With Lower Limb Amputations

Nearly 60-85% of Veterans with amputations experience pain at the location of the amputated limb called phantom limb pain (PLP). PLP is a major problem and can have a profound impact on Veteran's daily function and ability to fully participate in life. Although several rehabilitation interventions are promising, advances in novel rehabilitation interventions are limited. The objective of this project is to refine a mobile app for graded motor imagery in 12 Veterans with amputations and test the mobile app with 36 Veterans with amputations. For this pilot project, the investigators will measure the preliminary feasibility and acceptability of the intervention. Knowledge from this project will provide evidence to guide future larger studies of this graded motor imagery intervention. Developing novel strategies for chronic pain in this population will positively impact quality of life for Veterans with amputations.
