Ryan Duncan, PT, DPT, MSCI
Associate Professor of Physical Therapy & Neurology
Program in Physical Therapy
- Email: duncanr@wustl.edu
Ryan Duncan, PT, DPT, MSCI, is a physical therapist and Associate Professor of Physical Therapy and Neurology at Washington University in St. Louis. He completed his Bachelor’s of Health Science and Master’s degree in Physical Therapy at Maryville University in St. Louis in 2008. He completed his post-professional Doctor of Physical Therapy and Master’s of Science in Clinical Investigation at Washington University in St. Louis.
The broad focus of his research is to understand factors impacting movement in people with Parkinson’s disease as well as how movement changes in response to rehabilitation in this population. He has published more than 30 peer-reviewed manuscripts in this area. His current research is focused on understanding the biomechanical, sensory, and psychologic factors related to low back pain in people with Parkinson’s disease. His work is funded by the National Institutes of Health.
