Dr. Zehr is interested in how the human nervous system controls movement. He works to better understand how the spinal cord produces coordinated arm and leg movements during walking in order to improve the rehabilitation of walking after damage to the nervous system. For example, he seeks to determine whether exercises that coordinate arm and leg movements can help stroke victims recover. He also studies how arm and leg reflexes change over a cycle of rhythmic movement such as walking, swimming, or cycling.
Dr. Zehr is a Principal Investigator at ICORD. He is also a Professor in the Department of Neuroscience at the University of Victoria, and the Chair of the Michael Smith Foundation for Health Research.
He loves working with ICORD because it is very helpful as a networking tool; it allows him to reach other researchers. He also says that ICORD provides a great “overall context for research programs.”
Early in his career, Dr. Zehr was studying walking like most other researchers: by focusing on the legs. It wasn’t until he drew an armless stick figure for an article that he realized how odd it was to ignore arms in a study of walking. Since all other mammals move their forelegs in a coordinated manner with their hind legs, why not humans? Thus, a simple armless stick figure propelled Dr. Zehr into his study of coordinated movement.
Techniques employed in the lab:
- Nerve and muscle stimulation (electrophysiology)
- Muscle recordings (electromyography)
- Brain recordings (electroencephalography)
- Biomechanics of movement (kinematics & kinetics)
- Rhythmic arm and leg movement (integrated cycling, walking, and stepping)
Affiliation with organizations and societies:
- American Physiological Society (APS)
- Canadian Association for Neuroscience (CAN-ACN)
- Motor Control Journal
- Society for Neuroscience (SFN)
Some of Dr. Zehr’s recent major awards and accomplishments include:
- Science Educator Award (Society for Neuroscience, 2015)
- IPPY Silver Medal for Juvenile Fiction, “Project Superhero” (North American Independent Book Publishers, 2015)
- Craigdarroch Knowledge Mobilization Award for Research Communication (University of Victoria, 2012)
- Scholar, Biomedical Research Pillar (Michael Smith Foundation for Health Research, 2003-2008)
