An investigation of the Landing Error Scoring System and clinically assessable sport-related injury risk factors
type: CreativeWork
description: Background: Preventing sport-related lower-extremity injuries relies on identifying individuals at risk. The Landing Error Scoring System (LESS) is a clinical injury risk screening tool suitable for large-scale screening without expensive equipment. However, psychometric properties, influencing factors, and differences in methodological procedures reported between studies need further exploration to justify its use. Furthermore, it is debatable whether the double-leg jump-landing (DLJL) task used in the LESS is ecologically valid and reflects sport and injury-specific situations. Moreover, generalised hypermobility, the Movement-Specific Reinvestment Scale (MSRS), and dorsiflexion range of motion (ROM) have all been used to assess injury risk factors, although their influence on dynamic movements remains relatively unexplored. Aim: To explore the LESS and other clinically assessable sport-related injury risk factors. Methods: Two systematic reviews were undertaken: one on the psychometric properties of the LESS, and another on factors potentially influencing LESS scores. LESS outcomes between different final LESS score calculation methods, self-selected landing distance and landing distance set to 50% of body height, and Pre and Post information sessions on LESS scoring criteria and prior performance were compared using Generalised Estimating Equations, odds ratios, t-tests, McNemar’s, and Wilcoxon signed ranks tests. To determine which jump-landing task best represented the kinematics of a sport-specific and high injury risk task (i.e., unanticipated cutting), the degree of association based on intraclass correlation coefficients (ICC) of three-dimensional whole-body kinematics and ratings of subjective difficulty between unanticipated cutting and four jump-landings were compared using Friedman tests with post-hoc Wilcoxon signed-rank tests. Spearman rank correlation coefficients were calculated to investigate the relationship between LESS, Beighton hypermobility, …
