Psychometric properties of the Edinburgh Visual Gait Score in children with spastic cerebral palsy

Abstract Background To our knowledge, no other studies investigated the internal consistency of Edinburgh Visual Gait Score (EVGS). The aim study was to determine reliability and construct validity EVGS in children with cerebral palsy (CP). Results A total fifty CP were enrolled study. Participants evaluated Gross Motor Function Classification System (GMFCS), Wisconsin Scale (WGS), Gillette Functional Assessment Questionnaire (Gillette FAQ), Timed Up Go Test (TUG), (Rater-A Rater-B). Slow-motion video analysis used for visual gait analysis. inter-rater reliability, consistency, analyzed. intraclass correlation coefficient (ICC) score 0.947 (CI: 0.90–0.97). Inter-rater excellent (ICC>0.80). Cronbach’s alpha value 0.936, within acceptable range (0.70<α<0.95). In addition, standard error measurement (SEM 95 ) minimal detectable change (MDC scores 1.72 4.78, respectively. values (Rater-A) GMFCS, TUG, GFAQ, WGS 0.494, 0.661, −0.663, 0.611, On hand, (Rater-B) 0.492, 0.664, −0.714, 0.757, Except comparison GMFC, highly valid all correlational analyzes ( r >0.50). had moderate GMFCS both raters. Conclusion reliable valid. Internal is high, indicating a consistent structure assess CP.
