  • Oslo Sports Trauma Research Center - 208 - Video analysis of snowboard injuries
    Studies have suggested that the risk of injury in snowboarding is especially high among competitive snowboarders at elite level The FIS Injury Surveillance System established at Oslo Sport Trauma Research Center 2006 has reported that the injury incidence among World Cup snowboarders is alarmingly high One in three riders sustains an injury per season Over 30 of the injuries are serious injuries leading to long term absence from training and competition and unfortunately in some cases career ending The injury pattern is dominated by knee and head injuries and the most frequent types of injuries are joint and ligament injuries To reduce the risk of injury among World Cup snowboarders we have to know why and how injuries occur Little is known about the injury risk and the specific injury mechanisms associated with World Cup Snowboarding To date limited scientific documentation is available The aim of this study is therefore to describe in detail injury situations and mechanisms of injury in World Cup snowboarding Methods Video analysis and injury registration will be combined to record accurate and complete injury information Videotapes of injuries reported through the FIS Injury Surveillance System will be obtained retrospectively from the four last seasons 2006

    a time loss injury each season Many of these are severe 28 days and lead to a long term absence from training and competition Knee injuries particular tears of the anterior cruciate ligament ACL represent a major problem To reduce the risk of these serious knee injuries we have to know why and how the injuries occur So far the knowledge is limited The aim of this study is to describe in detail the mechanisms of injury among World Cup freestyle skiing with a particular focus on severe knee injuries ACL tears Methods Videotape of ACL tears reported through the FIS ISS has been recorded from four seasons 2006 10 More than 20 injuries have been captured on video and will be visually and biomechanically analyzed The injury cases will be visually analyzed by a group of experts and an analysis form will be developed in order to describe in detail the mechanisms of ACL tears This information will include an evaluation of the injury situation skiing situation and body motion In addition injury cases and matched controls will be compared to distinguish between injury and no injury situations Joint kinematics of ACL tears will be estimated by using a

  • Oslo Sports Trauma Research Center - 210 - The best way to interpret ECG in athletes
    competency in interpreting the ECGs In Italy the preparticipation screening PPS of ECG are conducted by sports physicians who attend postgraduate residency training programs in sports medicine and sports cardiology full time for 4 years and work in sports medical centers specifically devoted to periodical screening of athletes These physicians played a crucial role for achieving the accuracy of first line cardiovascular screening In the United States most PPS is performed by generalists without subspecialty training Objective To find the most efficient way to interpret the ECG of athletes during screening Methods 45 GPs and 45 cardiologists will be given anonymous demographic data positive findings from the questionnaires BP data and ECG with computer interpretation from ten players They will be asked to categorize the ECG as 1 abnormal 2 normal or 3 athletes heart The cardiologists answers at baseline will be compared with the GPs after intervention As intervention the GPs will learn the most important features in the new recommendations for interpreting ECG in athletes and they will be given a leaflet with the most important points After one month they will be asked to categorize ten new ECGs They will also be asked to recommend follow up

  • Oslo Sports Trauma Research Center - 217 - Knee function of top level female team handball and football players
    years of exposure to top level handball and football play influence an athlete s knee function in general The Knee and Osteoarthritis Outcome Score KOOS is a well established and validated self explanatory 42 item questionnaires developed to assess patient opinion about knee associated problems after ligament reconstruction or other surgical treatment Objectives To investigate knee function of elite female handball and football players with and without a previous ACL injury and thereby assess the impact of exposure top level play do have on players knee function In addition this project is to analyze whether ACL injured players return to elite sports with side to side differences and or a knee function score below that of non injured players Methods This study is part of an ongoing cohort study aimed at investigating risk factors for non contact ACL injuries among Norwegian elite female team sport players Since 2007 and until June 2010 a total of 321 team handball and 246 football players age 22 4 years have been included 68 12 of these with a previous ACL injury At baseline each player was asked to complete a detailed questionnaire covering sports participation history of previous injuries to the ankle knee

    identify athletes at potentially increased risk for injury there is a need for standardized and time efficient low cost assessment tools Such a tool should be easy to use and implement for large scale screening and at the same time provide valid and reliable data Objectives To assess the relationship between real time observational screening of frontal plane knee valgus and actual knee valgus angles and abduction moments calculated from three dimensional 3D motion analysis during a vertical drop jump landing task A second purpose was to investigate the inter rater agreement for 3 independent physiotherapists using the real time observational screening test Methods The current study is part of a larger cohort study aiming to investigate risk factors for ACL injuries in elite female football players ACL risk factor study Players who were expected to play in the elite league during the 2009 season were eligible for participation For the current study we used 2 of the screening tests real time observational screening of knee control and 3D motion analysis of a vertical drop jump task A total of 77 players were included and 60 provided complete data from all phases of the data collection Using real time observational

  • Oslo Sports Trauma Research Center - 33 - Determinants for knee valgus in a vertical drop jump
    a link has been suggested between high knee valgus angles and abduction moments and ACL injury in female athletes Moreover neuromuscular training programs focusing on improving frontal plane knee control and reducing knee valgus have been proven effective Given the relationship between knee valgus loads and knee injuries screening during dynamic tasks such as the vertical drop jump has been promoted to identify athletes at risk for knee injury However the underlying causes for an athlete to display greater knee valgus is not thoroughly investigated although they may be important for targeting our injury prevention efforts Objectives The purpose of this study was to investigate the combined relationship between anatomical and neuromuscular characteristics and peak knee valgus angles in a vertical drop jump landing We therefore aimed to assess whether greater measures of body height femur and tibia length anterior knee laxity and foot pronation and lower quadriceps hamstrings and hip abductor strength could predict greater peak knee valgus angles Methods The current study is part of a larger cohort study aiming to investigate risk factors for ACL injuries in elite female football players ACL risk factor study We included elite female football players participating in baseline screening tests from
