The Functional Movement Screen (FMS) is a popular test to evaluate the degree of painful, dysfunctional, and asymmetric movement patterns. Despite great interest in the FMS, test-retest reliability data have not been published.
To assess the test-retest and interrater reliability of the FMS and to compare the scoring by 1 rater during a live session and the same session on video.
Cross-sectional study.
Human performance laboratory in the sports medicine center.
A total of 21 female (age = 19.6 ± 1.5 years, height = 1.7 ± 0.1 m, mass = 64.4 ± 5.1 kg) and 18 male (age = 19.7 ± 1.0 years, height = 1.9 ± 0.1 m, mass = 80.1 ± 9.9 kg) National Collegiate Athletic Association Division IA varsity athletes volunteered.
INTERVENTION(S): Each athlete was tested and retested 1 week later by the same rater who also scored the athlete's first session from a video recording. Five other raters scored the video from the first session.
MAIN OUTCOME MEASURE(S): The Krippendorff α (K α) was used to assess the interrater reliability, whereas intraclass correlation coefficients (ICCs) were used to assess the test-retest reliability and reliability of live-versus-video scoring.
Good reliability was found for the test-retest (ICC = 0.6), and excellent reliability was found for the live-versus-video sessions (ICC = 0.92). Poor reliability was found for the interrater reliability (K α = .38).
The good test-retest and high live-versus-video session reliability show that the FMS is a usable tool within 1 rater. However, the low interrater K α values suggest that the FMS within the limits of generalization should not be used indiscriminately to detect deficiencies that place the athlete at greater risk for injury. The FMS interrater reliability may be improved with better training for the rater.
功能性运动测试（FMS）是一种流行的测试方法，用于评估疼痛、功能障碍和不对称运动模式的程度。尽管人们对 FMS 非常感兴趣，但尚未公布其测试-再测试的可靠性数据。
评估 FMS 的测试-再测试和组内可靠性，并比较一位评估者在现场和视频相同时段的评分。
横断面研究。
运动医学中心的人体表现实验室。
共有 21 名女性（年龄=19.6±1.5 岁，身高=1.7±0.1m，体重=64.4±5.1kg）和 18 名男性（年龄=19.7±1.0 岁，身高=1.9±0.1m，体重=80.1±9.9kg）国家大学体育协会一级运动员自愿参加。
每位运动员由同一位评估者在 1 周后进行测试和再测试，该评估者还根据视频记录对运动员的第一次测试进行评分。另外 5 名评估者对第一次测试的视频进行评分。
Krippendorff α（K α）用于评估组内可靠性，而组内相关系数（ICC）用于评估测试-再测试可靠性和现场与视频评分的可靠性。
测试-再测试的可靠性良好（ICC=0.6），现场与视频的可靠性极好（ICC=0.92）。组内评估者的可靠性较差（K α=0.38）。
良好的测试-再测试和高现场与视频测试的可靠性表明，FMS 在 1 名评估者内是一种可用的工具。然而，低组内 K α值表明，FMS 在推广的范围内不应不加区别地用于检测使运动员受伤风险增加的缺陷。FMS 的组内可靠性可能通过对评估者进行更好的培训来提高。
