Brain Reorganization in Arm Amputees

This study is being done to better understand the possible effects of upper limb loss on subsequent brain activity and movement abilities. Specifically, we are interested in determining if there are changes that occur in the side of the brain that controls your non-amputated arm. To accomplish this, we will perform a magnetic resonance imaging (MRI) scan of your brain, examine reaching movement patterns, and use Transcranial Magnetic Stimulation (TMS) to identify the regions of the brain responsible for upper limb muscles and observe the interactions between the two sides of your brain.

You are eligible for this study if you have had one-sided arm amputation (above or below elbow) for at least 6 months and are a current prosthetic user (at least once a month). Reimbursement will be provided.
