## Aim: The rett syndrome gross motor scale (rsgms) is an observational measurement, assessing gross motor skills in individuals with rett syndrome. a dutch version is lacking. the current study aims to translate and cross-culturally adapt the original rsmgs to dutch and assess its inter-rater and intra-rater reliability. ## Design: Translation and cross-cultural adaptation were performed in concordance with internationally accepted guidelines. a pretest was performed, and expert validation was assured. video data of three girls with rett syndrome was independently assessed by 27 physiotherapists via an online webinar to measure inter-rater reliability. additionally, videos of 17 individuals with rett syndrome were scored twice by two raters to assess intra-rater reliability. the reliability of the total score, the three subscale scores and the new items were analyzed using intraclass correlation coefficients (icc). ## Results: Good comprehensibility and expert validation of the rsmgs-nl was achieved, and four items were added to the original scale. inter-rater reliability for the total score was excellent (icc 0.97, 95% ci 0.89-0.99), and good to perfect inter-rater reliability fo
