It has been widely used as an independent variable in studies of spina bifida, but its inter-rater reliability has not previously been tested. The purpose of this study was to measure inter-rater reliability of FLOL testing and compare testing performed by a non-medically trained research associate to testing performed by a pediatric rehabilitation medicine specialist. METHODS: Children in a multi-disciplinary spina bifida clinic underwent FLOL grading by a non-medically trained research associate. On the same day, these children were also graded by a pediatric rehabilitation medicine specialist. Cohen\u2019s weighted kappa statistic was used to compare grading, with the rehabilitation medicine specialist considered the gold standard. RESULTS: A total of 71 patients participated. FLOL was graded for left and right leg for each participant, resulting in 142 measurements. Cohen\u2019s weighted kappa was \u03ba=\u200a0.809, with a standard error of 0.034 and 95% confidence interval 0.723\u20130.875, indicating substantial agreement. CONCLUSION: FLOL as measured according to the instructions of the National Spina Bifida Patient Registry by a non-medically trained researcher is a reliable method to grade lower extremity function in spina bifida.<\/jats:p>","DOI":"10.3233\/prm-220072","type":"journal-article","created":{"date-parts":[[2022,12,9]],"date-time":"2022-12-09T10:15:27Z","timestamp":1670580927000},"page":"587-591","source":"Crossref","is-referenced-by-count":2,"title":["Functional
