Summary

This study tests whether combining mirror therapy with a gentle brain stimulation technique (tDCS) can reduce phantom limb pain in people with leg amputations. 132 adults with chronic pain will be assigned to different treatment groups to see which approach works best. The goal is to find a better way to manage this common and distressing condition.
