title: Left-handedness as an injury risk factor in adolescents.
abstract: OBJECTIVE
  Left-handedness has been suggested as a risk factor for unintentional trauma. The objective of this study was to determine if left-handedness was associated with an increased frequency and severity of injury among adolescent school athletes.
  
  
  METHODS
  A questionnaire was administered to 634 junior and senior high school athletes during preparticipation examinations. The questionnaire consisted of a four-item handedness determination and history of past injury.
  
  
  RESULTS
  Left-handers more frequently reported having seen a physician in the previous year for treatment of an injury than did right-handers. A higher proportion of the left-handers than right-handers reported having been previously hospitalized for injury treatment. A higher proportion of left-handers than right-handers reported having previously had surgery for treatment of an injury.
  
  
  CONCLUSIONS
  Left-handedness appears to be a risk factor for injury among adolescent school athletes.
