The major area of Dr. Peckham's research is in rehabilitation engineering and neuroprostheses. Dr. Peckham's research effort focuses on functional restoration of the paralyzed upper extremity in individuals with spinal cord injury. He and collaborators have developed implantable neural prostheses which utilize electrical stimulation to control neuromuscular activation. They have implemented procedures to provide control of grasp-release in individuals with tetraplegia. This function enables individuals with central nervous system disability to regain the ability to perform essential activities of daily living. His present efforts concern the integration of technological rehabilitation and surgical approaches to restore functional capabilities.
