    intrinsic and extrinsic risk factors There are many potential explanations for high valgus moments in cutting and landing and poor balance may be a contributional factor However high valgus moments are well established as a risk factor for ACL injury Few studies have investigated balance as a determinant for ACL injury and no studies have investigated the possible relationship between balance test scores and valgus moments in the knee To

  • Oslo Sports Trauma Research Center - 219 - Can clinical tests predict ankle and knee injuries in female football players?
    injury risk have been conducted on male football players and more research is needed on injuries among female football players to gain knowledge Previous studies on injuries in female football players have shown that injuries mostly occur in the lower extremities and in particular to the ankle and knee To be able to prevent injuries to occur we need to know what causes the injuries However there are only a few studies on the relationship between clinical test performance before a football season and injuries occurring later in the season The master thesis is a part of a larger cohort study Risk factors for ACL injury for female elite handball and football players The project started in 2007 and will continue till the end of the 2012 season The main purpose in this study is to evaluate whether different biomechanical neuromuscular and anatomical factors can predict the risk of future ACL rupture The purpose of this Master thesis is to investigate whether performance on different clinical tests can predict ankle and knee injuries in female elite football players Method This study will include data on approximately 200 female elite football players tested before the 2009 season The testa included are

    and pathological changes No data is available regarding screening results from Nordic countries The need for redefining normal ECG values of athletes is evident The present study evaluates cardiac screening among male Norwegian football players in the elite divisions describing demographic data electrocardiography ECG and echocardiographic findings All results are compared to a control group Aims 1 To conduct a complete examination of Norwegian elite football players based on patient history ECG and related echocardiographic findings 2 To relate ECG findings to corresponding echocardiographic findings Methods The project included 594 football players in 28 of 30 eligible teams of the two Norwegian elite divisions and 43 age matched controls ECG and echocardiography was recorded at least one hour after physical activity The interpretation of ECG will be carried out according to the new recommendations for interpretation of 12 lead ECG in the athlete published in December 2009 They classify the abnormalities in two groups 1 common and training related ECG changes and 2 uncommon and training unrelated ECG changes The latter changes need work up to exclude or confirm the suspicion of an underlying cardiovascular condition carrying the risk of sudden death during sports The emphasis of the echo was

  • Oslo Sports Trauma Research Center - 170 - Nordic Football Injury Audit – Injury surveillance in the first leagues of Sweden (Allsvenskan) and Norway (Tippeligaen)
    by the final position in the league system Prevention of sports injury is a very challenging issue and can be seen as a four step sequence 1 the extent of the injury problem is evaluated through injury surveillance 2 injury risk factors and injury mechanisms are established 3 based on this information preventive strategies are introduced and 4 these strategies are evaluated by repeating step one This means that injury surveillance studies that evaluate the epidemiology of injuries are essential when aiming for prevention of injuries The main objective is to decrease the overall injury risk to elite football players The study is an attempt to create a consensus for data collection and a common injury database for the Nordic countries Methods All teams qualified for the 2010 season of the first leagues of Sweden Allsvenskan 16 teams and Norway Tippeligaen 16 teams will be invited to participate in the study All players with a first team contract are eligible to be included in the study The clubs will be provided with a standard computer based exposure registration form The club contact person will be responsible for filling in this form with data on the player s individual attendance and

  • Oslo Sports Trauma Research Center - 216 - Video analysis of an ACL injury situation in world cup alpine skiing using model-based image-matching technique
    Surveillance System FIS ISS established at the Oslo Sports Trauma Research Center OSTRC has shown that one of three athletes in World Cup alpine skiing sustain an injury per season Approximately 30 of all injuries are serious injuries leading to long term absence from training and competition Knee injuries particular tears of the anterior cruciate ligament ACL represent a major problem A precise description of the injury mechanism is critical to be able to reduce the risk of ACL injuries Video analysis of injury tapes is the only method available to extract biomechanical information on the mechanism However video analysis has been limited to simple visual inspection which has been shown to be inaccurate even among experienced researchers Alternatively a model based image matching MBIM technique has been developed to extract joint kinematics from video recordings using one or more uncalibrated cameras MBIM technique has been validated in non injury situations in a laboratory environment and also has been found to be feasible for use in actual ACL injury situations The aim of this project is to describe in detail mechanisms of ACL injury in World Cup alpine skiing using MBIM technique Methods From videotapes of ACL tears reported through
