en Video Analysis of Acute Hamstring Injury Mechanisms During Deadlifts حرکت‌شناسی و آسيب‌های ورزشی Kinesiology and Sport Injuries مقاله اصیل Original Article <div style="text-align: justify;">Background. Existing studies on the mechanisms leading to acute hamstring injury are limited by reliance on author extrapolation and patient recall for injury details. Objectives. This study aims to determine potential mechanisms for acute hamstring strain injuries during deadlifts via videographic observations in vivo. Methods. Videos were searched on the website “YouTube.com” using each of the phrases “hamstring rupture”, “hamstring tear”, “hamstring injury”, “hamstring strain”, and “hamstring pull”, combined individually with the terms “deadlift”, “powerlifting”, and “competition”. An orthopaedic surgeon validated 16 video clips based on pre-set criteria. Results. 16 injury events were analyzed. Hip flexion (n=11) and knee semi-flexion (n=16) were the most common positions leading to injury. The most common injury pattern was a combination of hip flexion with knee semi-flexion and eccentric hamstring loading (n=11). Concentric hamstring loading was observed leading to injury in 3 cases. Conclusion. Acute hamstring injuries during deadlifts occurred by eccentric hamstring loading with a semi-flexed knee and a flexed or semi-flexed hip, or by concentric hamstring loading with a semi-flexed knee and semi-flexed hip.</div> Hamstring Muscles, Video Recording, Leg Injuries, Sports. 0 0 http://aassjournal.com/browse.php?a_code=A-11-2178-1&slc_lang=en&sid=1 Andre Dao adao@qmed.ca 100319475328460013251 0009-0001-9664-354X Yes Queen’s School of Medicine, Queen’s University, Kingston, ON, Canada Flaviu Trifoi ftrifoi@uwo.ca 100319475328460013252 100319475328460013252 No Schulich School of Medicine and Dentistry, Western University, London, ON, Canada Thomas Qu thomasqu99@gmail.com 100319475328460013253 100319475328460013253 No Department of Biochemistry, Western University, London, ON, Canada Soroush Nedaie soroush.nedaie@medportal.ca 100319475328460013254 100319475328460013254 No Michael DeGroote School of Medicine, McMaster University, Hamilton, ON, Canada Geoff MacDonald geoff.macdonald@tribemedical.com 100319475328460013255 100319475328460013255 No Tribe Medical Group, Toronto, ON, Canada.
