Dr. Susan E. Mackinnon is a plastic surgeon whose pioneering work in nerve transfer surgery is restoring movement to limbs that many doctors believe to be permanently paralyzed. Loren was fifteen when she was brutally stabbed five times, severing the nerves in her neck. Michael was facing a dead-end diagnosis after a freak chain saw accident paralyzed his arm. Chelsey survived a horrific late night car accident but her arm was also now useless.  A Spark of Nerve follows the charismatic Mackinnon and several of her patients for three years as their emotional stories unfold from trauma and disappointment to hope and finally joy as freedom of movement is slowly regained. We also visit the Walter Reed Peripheral Nerve Clinic to see how these little-known surgeries are being used to help our wounded soldiers returning from the Middle East conflicts.  A Spark of Nerve is an inspiring story of medical innovation and amazing personal triumph!
