Title: Optimizing Rehabilitation for Phantom Limb Pain Using Mirror Therapy and Transcranial Direct Current Stimulation (tDCS)
Brief Summary: This is a two-site study that explores the effects of mirror therapy and transcranial Direct Current Stimulation (tDCS, Soterix ©) in a randomized factorial controlled trial in which patients will be assigned to one of four groups: active tDCS and active MT; sham tDCS and active MT; active tDCS and sham MT (which consists of using a covered mirror for the therapy); and both sham tDCS and sham MT (covered mirror).

   2. Presence of any preexisting unstable medical conditions, or conditions that may increase the risk of stimulation such as uncontrolled epilepsy.
   3. Presence of history of severe cranial trauma with alteration of the cranial anatomy or metallic intracranial implants.
3. None fluent in the English language.

   * Ferromagnetic metal in the head (e.g., plates or pins, bullets, shrapnel)
   * Implanted neck or head electronic medical devices (e.g., cochlear implants, vagus nerve stimulator)
4. History of chronic pain previous to the amputation.
5. Head injury resulting in loss of consciousness for at least 30 min or pos-traumatic amnesia for greater than 24 hours, as self-reported
6. Unstable medical conditions (e.g. uncontrolled diabetes, uncompensated cardiac issues, heart failure or chronic obstructive pulmonary disease).
7. Uncontrolled Epilepsy or prior seizures within the last 1 year.
