Femoral kontroll blant idrettsaktive kvinner : testutvikling og sammenheng med skadehistorikk

Abstract

Purpose: Non-contact knee injuries are often the topic of discussion in relation to injury prevention. The purpose of this study was to develop a standardized test and a standardized analysis method for quantifying changes in the femoral control in a simple but reliable way. We also wanted to quantify the relationship between femoral control and injury history in the sample. Method: Female athletes (n = 95, age = 18 ± 1 years old) who were active in various sports, conducted two weak links test and answered a questionnaire regarding their history of lower limb injury. Weak links were defined as inward rotation and / or abduction of the femur under one legged squat and fall and landing test. Results: The test of one legged squat was the only reported injury group on the right leg, which showed significant greater excessive inward rotation compared with the uninjured group (p <0.001). The test fall and landing showed no differences between previously injured and uninjured subjects. Conclusion: Only one legged squat with right leg was related to the injury history in our group. Fall and landing revealed reduced core stability. This was not associated with injury history. Landing pattern revealed the decreased core stability, but there was a tendency for asymmetric landing. One legged squat showed no correlation with the injury history on the left leg. Measurement of femoral movement with 2-dimensinal video analysis gives meaningful and repeatable data. Key words: Core stability, quantifying femoral control, injury history versus femoral control
