Professor Molly Verrier trained as a physical and occupational therapist at the University of Toronto graduating in 1970. She practiced neurological physical therapy at the Toronto Western Hospital. Upon graduation from graduate studies in Clinical Neurophysiology and Health Science at McMaster University, 1978 she joined the physical therapy teaching faculty at the University of Toronto and became the Lead Scientist of the U of T Human Neuromotor Control Laboratory at the Playfair Neuroscience Unit. Between 1988 and 1994 she was the Director of the Division of Physical Therapy in U of T’s Department of Rehabilitation Medicine. In 1994 Prof. Verrier became the first Chair of the Department of Physical Therapy and the Graduate Department of Rehabilitation Science in the Faculty of Medicine at the University of Toronto. As chair, over the next decade along with a group of talented PT and OT faculty, she implemented a BSc PT Evidence Based Curriculum, a Professional Master's Program in Physical Therapy, and U of T’s first MSc and PhD Programs in Rehabilitation Science.

Research & Scholarly Activities

Prof. Verrier has conducted research on pharmaceutical interventions, basic neurophysiology, spasticity, short and long latency responses in patients with spinal cord injury (SCI) Parkinson's disease and stroke. She has investigated both disordered postural control and gait in stroke and acquired head injury and SCI. Prof. Verrier as well as studying cortical reorganization, sensorimotor recovery, rehabilitation interventions and service delivery following traumatic and non–traumatic spinal cord injury. Her research has included:

  • Utilization of electromyography, kinetic and kinematic analysis for understanding neurological disorders
  • Development of clinical neurological assessments for sensorimotor control Community Balance and Mobility Scale (CB&M), Graded Redefined Assessment of Strength, Sensibility  and Prehension (GRASSP), Toronto Rehabilitation Institute Hand Function Test (TRI-HFT) Standing and Walking Assessment Tool (SWAT )
  • Development of novel intervention strategies for restorative motor control for posture, mobility and function, and
  • Evaluation of neurotherapeutic techniques and neurorehabilitation service delivery.
