Technology Development for Physical Rehabilitation of Patients With Upper Extremity Motor Deficits (RePlay)

Injuries and disease processes that produce upper extremity deficits are devastating to patients and their families. One potential avenue to treat these neurological disorders is through the enhancement of neural plasticity, which is the ability of the brain to reorganize and recover following insult. After a minor injury, the brain undergoes beneficial neural plasticity, compensating for altered neural activity to restore normal function. However, in the cases of moderate to severe injury and disease, e.g. spinal cord injury (SCI), insufficient or improper plasticity limits recovery, leaving patients with long-term disability. Therefore, methods that can drive robust and specific plasticity have great potential to treat neurological injuries and disease. The Texas Biomedical Device Center (TXBDC) at UT Dallas has developed a groundbreaking therapy, called Targeted Plasticity Therapy (TPT), which pairs traditional motor, sensory, and cognitive rehabilitation with precise stimulation of the vagus nerve, to guide such robust and specific plasticity to treat a wide range of neurological deficits.
