RESUMEN
Abstract Aims: To investigate the inter-and intra-rater agreement of the Dynamic Movement Assessment (DMA™) risk classification. Method: In this study, after the anthropometric measurements were made, 17 female soccer athletes were filmed performing the six DMA™ tests (full squat, step-up, single-leg squat, jump test, test plank, and side plank). Both, major and secondary deviations, were observed during the tests. Two experienced health professionals performed video analysis using Kinovea 8.15.0 (inter-rater agreement). To assess the intra-rater agreement, the same video analysis was performed two months later. Participants were rated from 0 to 21 points and at low, medium, moderate, and high risk of developing musculoskeletal injuries. To assess the reliability of the assessment of movement patterns of DMA, the intraclass correlation coefficient (ICC) was performed with a 2-way random-effects model with an absolute agreement (inter-rater) and a 2-way mixed-effects model and consistency (intra-rater). Weighted Kappa Agreement Analysis (kw) was performed with linear weights to assess the level of agreement related to the risk classification of DMA (high, moderate, medium, or minimum). The Analysis was performed with StatsDirect v.3 and SPSS (23.0). Results: Comparing the number of points between the inter-and intra-rater, the ICC was 0.91 (95% CI = 0.74-0.97) and 0.84 (95% CI = 0.59-0.94), respectively, with kw = 0.46 (P = 0.02) intra -rater and kw = 0.46 (P = 0.006) inter-rater (Table 9). Conclusion: DMA has excellent inter-and intra-rater reliability to evaluate movement patterns and classify the risk of musculoskeletal injuries.
