Functional Movement Screen (FMS), intraclass coefficient (ICC), Interrater reliability, Physical Therapy


Purpose: The purpose of this study was to assess the interrater reliability of the most recent Functional Movement Screen (FMS), between four second-year physical therapy students. The most recent FMS has added the ankle clearing test (pain and mobility categories) after the inline lunge and modified the rotary stability movement pattern and criteria for scoring. To our knowledge, there has not been a reliability study completed with the most recent additions and modifications of the FMS.

Methods: Forty-five physical therapy students participated and were videotaped completing the Functional Movement Screen (FMS) and were rated by four current second-year physical therapy students. The videos were then independently observed and scored by four second-year physical therapy students, also known as the raters in the study. The intraclass coefficient (ICC) was analyzed using reliability analysis: statistics on SPSS.

Results: The inter-rater reliability was highest for scoring the rotary stability test ICC 0.96, while the deep squat was the least reliable ICC 0.78. Overall, the total scores showed reliability between the four raters with an ICC of 0.95. All the new scoring criteria produced good to great inter-rater reliability, with the exception of the ankle mobility clearing test. Conclusion: This study showed the inter-rater reliability between four second-year physical therapy students was good to excellent across all portions of the FMS.
