Research interests
Dr. Roy's research was aimed at understanding the neurocognitive and neuromotor mechanisms underlying how movements are learned and controlled. His approach involved examining normal healthy persons as well as those with neurologic disorders such as stroke, Alzheimer's disease and Down syndrome. Since many of these disorders arise in older adults, his work also focused on the effects of aging. Prehension, movement sequencing, limb gesturing and tool use and disruptions to these movements seen in various neurologic disorders were all of interest.
One line of research was concerned with identifying the basis of manual asymmetries in performance and how these asymmetries vary with and are related to measures of hand preference.
Another focus was on apraxia, a disorder in limb gesturing and tool use. In this work he developed a cognitive neuropsychological model of apraxia to identify disruptions at different stages of gesture production and then to relate these to lesion localization in the brain.
A more applied aspect of research built upon his expertise as a clinical neuropsychologist and involved studying the effects of concussion and traumatic brain injury. One focus was on concussion in hockey. Dr. Roy acted as a consultant to several teams in the Ontario Hockey (Major Junior A) League in the use of neuropsychological assessments as part of return to play guidelines for players who have suffered a concussion. He was an advisor to a committee of the Ontario Brain Injury Association on concussion in hockey. He was also a co-investigator on a national study of concussion in hockey which is aimed at examining the incidence of concussion, establishing return to play guidelines and developing educational materials on concussion for coaches and players and their families.
