Beth Fisher is an Associate Professor of Clinical Physical Therapy in the Division of Biokinesiology and Physical Therapy at the University of Southern California. She holds a joint appointment in the Department of Neurology, Keck School of Medicine at USC. Dr. Fisher is the director of the Neuroplasticity and Imaging Laboratory primarily using Transcranial Magnetic Stimulation (TMS) to investigate brain-behavior relationships during motor skill learning and motor control in both non-disabled individuals and individuals with neurologic disorders. Additionally, Dr. Fisher is the director of the University of Southern California/Rancho Los Amigos National Rehabilitation Center (USC/RLANRC) Residency Program in Neurologic Physical Therapy. She previously worked at Rancho Los Amigos Medical Center on the Adult Neurology and Brain Injury Services and continues to consult and teach nationally and internationally on current concepts for the treatment of adults with neurological disorders. During her years as a clinician and rehabilitation specialist, it was her greatest ambition to be a part of developing physical therapy interventions that would maximize neural and behavioral recovery in individuals suffering from pathological conditions affecting the nervous system. Towards this goal she is currently studying the effects of high-intensity exercise on functional recovery and brain repair in Parkinson’s disease using TMS and Positron Emission Tomography (PET) as markers of neuroplasticity. Additionally, she is studying brain changes using TMS in individuals with stroke undergoing skilled rehabilitation; healthy individuals learning complex motor skills and individuals undergoing ankle manipulation as part of a physical therapy program for ankle
