Kessler Foundation Research Center improves the quality of life for people with physical and cognitive disabilities through rehabilitation research in its six specialized laboratories under the leadership of noted research directors—Human Performance & Engineering Research, Neuropsychology & Neuroscience, Outcomes & Assessment Research, Spinal Cord Injury Research, Stroke Rehabilitation Research, and Traumatic Brain Injury Research. While the staff of each laboratory has expertise in a particular area, collaboration often enhances progress toward finding ways to overcome the obstacles faced by people with disabilities caused by brain injury, spinal cord injury, multiple sclerosis, stroke, arthritis, and other chronic neurological and orthopedic conditions.
