Epidemiology of all‐complaint injuries in youth basketball

“…Predicated on previous epidemiological studies, an injury was defined as follows: any physical complaint, including pain, ache, joint instability, stiffness, or any other complaint resulting from participating in basketball‐related activities, including but irrespective of the need for medical attention (seeking care from a trainer or medical practitioner) or time loss (inability to complete a basketball‐related session, or participate in one or more days after the onset of injury) 23,28‐30 . Further, an injury was identified as “acute” if its onset was sudden and traumatic and clearly associated with an identifiable event and “overuse” if its onset, whether gradual or sudden, was unidentifiable with any event 27,28 . Additionally, a recurrent injury was defined as a re‐injury, that is, a repeat episode of a fully recovered index injury 31 …”

“…Participants self‐reported any knee or ankle injuries weekly on an adapted OSTRC Knee and Ankle Questionnaires (Appendix ), through an online mobile app (MetricWire™) or paper version. The knee version of the adapted questionnaire was previously validated for self‐report of all‐complaint knee injuries that focused on patellar tendinopathy 27 . The original OSTRC Questionnaire has been shown to be valid for reporting all‐complaint injuries, 30,32 and it has been extensively used in previous studies to capture acute and overuse injuries in different body locations 22,26,33 .…”

“…It is speculated that injury rates have been previously under‐reported in youth basketball players based on injury definitions often restricted to medical attention and/or time loss 20,24 . Self‐report methodologies, including the use of the Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC‐O), have been shown to be a more accurate surveillance method for recording overuse injuries in athletes in a variety of sports and across levels of participation 23,25‐27 . The objectives of this study were to evaluate the incidence and characteristics of all‐complaint injuries, including acute and overuse injuries, in male and female youth basketball players, using a combination of methods, including self‐report.…”
