Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals who have received a unilateral hand transplant or have undergone nerve repair and are in the chronic recovery stage.

Probably not a fit

Patients with significant brain trauma or serious psychiatric conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to enhance functional recovery in patients with upper extremity nerve injuries by combining behavioral training with transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique. The approach is based on recent neuroscience discoveries that suggest adaptive brain plasticity can be harnessed to improve rehabilitation outcomes. Participants will be individuals who have undergone hand transplantation or nerve repair and are in the chronic recovery phase, approximately 12 to 18 months post-surgery. The study will evaluate the effectiveness of this innovative rehabilitation program compared to standard care.

Why it matters

Potential benefit: If successful, this approach could significantly improve functional recovery and quality of life for patients with upper extremity nerve injuries.

How similar studies have gone: Other studies have shown promise in using brain stimulation techniques for rehabilitation, suggesting potential success for this novel approach.

Inclusion Criteria:

* Individuals whom have received a unilateral allogeneic transplantation proximal to the wrist and are at the chronic stage of recovery (approx. 12 - 18 months following surgery, when Tinel's sign reaches the distal fingertips).
* Individuals whom have undergone a complete amputation the hand between the wrist and elbow followed by successful re-attachment and are at the chronic stage of recovery (approx. 12 - 18 months following surgery, when Tinel's sign reaches the distal fingertips).
* Individuals whom have undergone repairs of the median, ulnar, or other related or nearby nerve(s) following complex volar forearm lacerations or other injuries between the distal wrist crease and the flexor musculotendinous junctions. Individuals must be at the chronic stage of recovery (approx. 12 - 18 months following surgery, when Tinel's sign reaches the distal fingertips).

Exclusion Criteria:
