Abstract: Objictive:Functional Movement Screen (FMS) was widely accepted. However, its rater reliability is controversial. In order to expand the scope of its application, this article conducts an empirical study on its inter-rater reliability. Methods: 37 basketball and volleyball elite players were sampled to participate in this study and 6 raters were chosen as the subjects. In the experiment, six raters gave their scores for athletes according to FMS evaluation rules, then each rater’s reliability was evaluated through statistical analysis of their scores. Results: (1)High correlation (0.723≤W≤0.904) and consistency(0.6<k≤1) were found among raters scores for push-up, shoulder mobility, deep squat, straight leg raise and rotary stability. (2) Lower correlation (0.380≤W≤0.570) and consistency(k<0.2) were found for hurdle step, in-line lunge, but the differences were not significant differences. Conclusion:The overall inter-rater reliability of FMS is good.
