Treatment of Phantom Limb Pain by Intensive Visual Simulation Therapy

Phantom limb pain (PLP) is reported by as much as 80 % of patients following an amputation. There is increasing knowledge of the relation between PLP and maladaptive changes in brain cortical regions. Research has shown that the sight of an "intact arm" moving in a mirror may reverse maladaptions (Mirror-therapy, MT) and reduce PLP. The current project will implement a digital and modernized version of MT, i.e. Intensive Visual Simulation Therapy (IVS-T). Pilot studies have shown promising results on pain reduction in people with phantom limb pain when using IVS-T. However, there is a lack of RCT studies on this patient population. This study is a 2-arm randomized controlled trial (RCT) investigating the effectiveness of IVS-T compared with usual care in person with unilateral upper- or lower limb amputation with chronic phantom limb pain. The primary aim of the study is to investigate if IVS treatment is superior to usual care in reducing phantom limb pain intensity after 2 months of treatment in unilateral amputees with moderate to severe PLP. The study will furthermore explore quality of life, analgesic consumption, phantom pain characteristics, mobility, and disability. In addition, the study utilizes brain imagery during treatments to investigate neural plasticity and the association between PLP and maladaptive cortical changes.
