RELIABILITY of a MOVEMENT QUALITY ASSESSMENT TOOL to GUIDE EXERCISE PRESCRIPTION (MOVEMENTSCREEN)

Abstract

BACKGROUND/PURPOSE: Movement quality is commonly assessed to identify movement limitations and guide exercise prescription. Rapid growth in the movement assessment landscape has led to the development and utilization of various movement quality assessments, many without reliability estimates. MovementSCREEN is a novel, tablet-based, video-recorded movement assessment tool, currently without published reliability information. Therefore, the purpose of this study was to determine the intra and inter-rater reliability of the MovementSCREEN, including the impact of rater experience, and provide estimates of measurement error and minimal detectable change. STUDY DESIGN: Cross-sectional design; reliability study. METHODS: ) for the overall score for each movement, and the composite score of movement quality, were calculated. RESULTS: was 6 points, with an ICC 0.901. CONCLUSIONS: The MovementSCREEN can assess movement quality with fair to high reliability on a test-retest basis when used by experienced assessors, although reliability scores decrease in novice assessors. Comparisons between assessors involve greater error. Therefore, the training of inexperienced assessors is recommended to improve reliability. LEVEL OF EVIDENCE: 2b.
