Founder, R2P™ Concussion Management
Since 2013, I have provided evidence-based concussion management education to over 1000 clinicians globally.
Biography
Dr. Jacquie van Ierssel is a CAMPT physiotherapist and postdoctoral fellow at the Children’s Hospital of Eastern Ontario. Her ongoing research focuses on improving how to measure balance and functional outcomes following concussion to aid clinical decision-making regarding recovery and return to sport. Her research has been published in high-impact peer reviewed journals. In her doctoral research she developed the Concussion Recovery Questionnaire (CORE-Q), a concussion-specific measure of the functional capacity that measures how long a person can perform a task before the onset or worsening of symptoms. Jacquie founded R2P™ Concussion Management to promote a systematic and evidence based approach to best-practice concussion assessment and treatment has instructed over 1000 healthcare professionals globally. She is an expert panelist for the Ontario Neurotrauma Foundation Living pediatric Concussion Guidelines, and has contributed to the WSIB mTBI program of care guidelines. She has been a clinical instructor at the University of Toronto Department of Physical Therapy and is past chair of Sport Physiotherapy Canada, Ontario Section. As an invited speaker at many professional conferences, Jacquie has spoken about the evidence-based management of concussion across the country.
She graduated from the Department of Physical Therapy at the University of Toronto in 1998, after first obtaining a Bachelor of Physical Education degree from the University of Western Ontario in 1994. She also holds an MSc (Rehabilitation) from McMaster University, where her research focused on return to sport following ACL reconstruction. Jacquie has gone on to complete the highest level of post-graduate diplomas in both advanced orthopaedics and sports physiotherapy, earning her FCAMPT in 2004 and SPC diploma in 2007. She has also successfully completed a competency-based certification in vestibular rehabilitation at Emory University. Additionally, she obtained her certification in acupuncture from the Canadian Acupuncture Foundation of Canada, and is a nationally-accredited certified strength and conditioning specialist and a certified sports first responder.
As an orthopaedic and sport physiotherapist, Jacquie has over 20 years of experience working with concussed athletes from a recreational level through to and including Olympic athletes. She has worked extensively with national sports teams to provide on-field and clinical care with Gymnastics Canada, Skate Canada, Athletics Canada, Special Olympics, and the University of Toronto. Her continuum of care included facilitating neurocognitive baseline testing, acute on-field assessment of injured athletes, management of acute and persistent postconcussion symptoms, exercise progressions, and return to school, work, and sport.
