My funded research is with the Child Stroke Outcome Project at the Hospital for Sick Children, Toronto. I lead the component of the study that conducts descriptive and exploratory studies on occupational performance and quality of life and its predictors in child survivors of stroke and their families. Recent research examines effectiveness of intervention on functional and occupational outcomes for children with chronic hemiparesis as a result of ischemic stroke. These include a student led project on Cognitive Orientation to daily Occupational Performance (CO-OP) and a multidisciplinary pilot study on the effectiveness of repetitive transcranial magnetic stimulation (TMS) on functional hand skills.
