Dr. Ramzi Ben-Youssef is a physical medicine and rehabilitation specialist who trained at Loma Linda University Medical Center and at Rancho Los Amigos National Rehabilitation Center in California. During his residency, he served as chief resident, and after residency he pursued additional neuro-rehabilitation training at Rancho Los Amigos with special focus on spinal cord medicine, stroke and brain injury rehabilitation. He was subsequently hired by Rancho Los Amigos as chief of the Spinal Cord Injury Outpatient Center. During that period he helped establish the Spinal Cord Injury Patient Centered Medical Home and worked as its acting medical director. He later joined the University of Southern California with the department of neurology as an assistant professor of neurology and physical medicine and rehabilitation. In this position, he helped establish and launch the Acute Inpatient Rehabilitation Unit and he is the unit’s medical director. Dr Ben-Youssef has a background in surgery and research. Early in his career, he did an internship in general surgery at the University of Southern California, then he did a second year of surgical training as a resident at Loma Linda University Medical Center, followed by four years of clinical research in solid organ transplantation and solid organ transplantation immunology, and he published many research papers and abstracts and he presented at national and international medical meetings. Dr. Ben-Youssef has also published many papers and abstracts in the field of rehabilitation medicine and is currently involved in two research projects with USC and Rancho Los Amigos studying robotic exoskeleton devices and stem cell therapy in spinal cord injured patients.
