At present, it is unknown whether children and adolescents are at a comparable risk of sustaining a concussion compared to adults. This study reconstructed the impact kinematics of concussive falls for children, adolescents, and adults and simulated the associated brain tissue deformations. Patients included in this study were diagnosed with a concussion as defined by the Zurich Consensus guidelines. Eleven child, 10 adolescent, and 11 adult falls were simulated using mathematical dynamic models(MADYMO), with three ellipsoid pedestrian models sized to each age group. Laboratory impact reconstruction was conducted using Hybrid III head forms, with finite element model simulations of the brain tissue response using recorded impact kinematics from the reconstructions. The results of the child group showed lower responses than the adolescent group for impact variables of impact velocity, peak linear acceleration, and peak rotational acceleration but no statistical differences existed for any other groups. Finite element model simulations showed the child group to have lower strain values than both the adolescent and adult groups. There were no statistical differences between the adolescent and adult groups for any variables examined in this study. With the cases included in this study, young children sustained concussive injuries at lower modeled brain strains than adolescents and adults, supporting the theory that children may be more susceptible to concussive impacts than adolescents or adults.<\/jats:p>","DOI":"10.1115\/1.4045808","type":"journal-article","created":{"date-parts":[[2019,12,31]],"date-time":"2019-12-31T08:13:46Z","timestamp":1577780026000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":5,"title":["Biomechanical Comparison of Real World Concussive Impacts in Children, Adolescents, and Adults"],"prefix":"10.1115","volume":"142","author":[{"given":"Lauren","family":"Dawson","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Division of Emergency Medicine, Children's Hospital of Eastern Ontario Research Institute, 401 Smyth Ave- Rm R139, Ottawa, ON K1H 8L1, Canada; Human Kinetics, University of Ottawa, Ottawa, ON K1N 6N5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Koncan","sequence":"first","affiliation":[{"name":"Human Kinetics, University of Ottawa, Ottawa, ON K1N 6N5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Post","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Division of Emergency Medicine, Children's Hospital of Eastern Ontario Research Institute, 401 Smyth Ave- Rm R139, Ottawa, ON K1H 8L1, Canada; Human Kinetics, University of Ottawa, Ottawa, ON K1N 6N5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roger","family":"Zemek","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Division of Emergency Medicine, Children's Hospital of Eastern Ontario Research Institute, 401 Smyth Ave- Rm R139, Ottawa, ON K1H 8L1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael D.","family":"Gilchrist","sequence":"first","affiliation":[{"name":"School of Mechanical & Materials Engineering, University College Dublin, Dublin 4, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shawn","family":"Marshall","sequence":"first","affiliation":[{"name":"Department Head, Physical Medicine and Rehabilitation Bruyere Continuing Care, Ottawa Hospital Research Institute, Ottawa, ON K1Y 4E9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.
