BACKGROUND & OBJECTIVE
Fear of re-injury has previously been associated with lower rates of return to sport, impaired objective measures and increased risk of re-injury. A qualitative assessment for fear of re-injury has previously been studied alongside perceived ability to perform, but this paper looked to correlate patients’ perception of fear with kinematic objective data. Using the Tampa Scale of Kinesiophobia-11 and the biomechanics involved in preparation and landing phases of a jump-land task, it was hypothesised that those with greater fear of injury would demonstrate increased frontal plane movements, decreased sagittal plane movements and increased quadricep activation.
35 female recreational athletes, 2 years post ACL reconstruction, were asked to complete a questionnaire (TSK-11) to evaluate “fear of injury” alongside a measure of jumping and landing. Using 3D motion analysis, EMG and force plate data, the participants performed 5 trials to create biomechanical profiles which were then assessed for statistical significance and correlation against fear of injury.
Fear has a significant, negative relationship on trunk, hip and knee flexion angles, meaning that fearful participants tend to land with low degrees of flexion in what could be considered a “stiff” landing mechanism. There was also a positive relationship
