Research Interests
Dr. Park's research focuses on 1) underlying neurophysiological mechanisms for deficient motor control and learning in elder adults and individuals with neurological diseases such as stroke, spinal cord injury, and cerebral palsy, 2) developing novel rehabilitation tools and protocols for improving their functional motor control with emphasis on walking and balance, and 3) behavioral and neural changes in response to rehabilitative interventions.
