- Abstract
Introduction: Hop tests are used to assess knee function but outcomes often reflect rather performance than movement quality, which is crucial for proper knee function.1 Objectives: The movement quality scoring tool "Quality First", focusing on movement related risk factors for knee injury, was developed and quality criteria were assessed. Moreover, movement quality was correlated with performance and a comparison of real-time versus slow-motion analysis was executed. Study Design: Cross-sectional study in a clinical setting. Methods: 34 participants performed various hop tests and 2D-videos were evaluated using "Quality First". Content validity was assessed from the perspective of professionals, for interpretability, classical test theory was employed. Cron-bach's α was calculated to evaluate internal consistency. Intraclass correlation coefficients (ICC2,3), standard error of measurements (SEM) and minimal detectable changes (MDC) were analyzed to assess reliability. Hop performance (Limb- Symmetry-Index, LSI) was correlated with the "Quality First" total score (Spearman) and Bland- Altman analysis was performed for method comparison (slow-motion, real-time). Results: Content validity resulted in the final inclusion of single-leg hop for distance, vertical hop, and side hop test covering sagittal, vertical, and transversal plane. "Quality First" consists finally of 15 items on a 4-point scale and obtained a sufficient Cronbach's α. The interrater reliability showed ICC2s from 0.45-0.60, with SEMs ranging from 1.46-1.73 and MDCs from 4.06-4.80. Intrarater reliability revealed ICC3s from 0.73-0.85 with SEMs ranging from 0.89-1.09 and MDCs from 2.47-3.01. No correlations between LSIs and "Quality First" were found (r=-0.1-0.02, p=0.65-0.93). Bland-Altman analysis revealed no systematic mean differences between real-time and slow-motion except for the vertical hop (0.8 points). Conclusion: "Quality First" can be a promising and time-efficient tool to assess movement quality showing fair to good interrater- and good to excellent intrarater-reliability. Patient progress of movement quality in hop tests should be monitored in addition to performance.
