Sidestep cuts between 60° and 180° and one-leg landings have been identified as the main mechanisms of ACL injuries in several sports. This study sought to determine intra- and inter-rater reliability of a qualitative tool to assess high-risk movements in a 90° change of direction when the test is applied in a real framework of sport practice. Female footballers from two teams ( = 38) participated in this study and were asked to perform 90° cutting trials to each side, which were simultaneously filmed from a frontal and a sagittal view. A total of 61 cases were selected for 2D qualitative observational analysis by three raters. Poor reliability was found among each pair of raters as well as moderate reliability when the Cutting Movement Assessment Score (CMAS) was given by the same rater at different moments, but with too high a minimum detectable change. On the other hand, raters presented a significant, as well as moderate-to-good intra-rater reliability for most items of the CMAS tool. There was, however, non-significant reliability between observers in rating most check-points of the tool. For these reasons, more objective guidelines and clearer definitions for each criterion within the CMAS, as well as a longer, standardised training period for novel observers, would be highly recommended to improve the reliability of this tool in an applied context with female footballers.
在多项运动中，60°到 180°的侧步和单腿着地被认为是 ACL 损伤的主要机制。本研究旨在确定一种定性工具在实际运动实践框架中评估 90°变向时高危动作的内部和外部评分者可靠性。来自两个球队的女足球员（=38）参加了这项研究，并被要求向两侧进行 90°切割试验，这些试验同时从前视和侧视拍摄。共有 61 个病例被选择用于由三名评分者进行 2D 定性观察分析。每个评分者之间的可靠性都较差，而当同一个评分者在不同时间使用切割运动评估评分（CMAS）时，可靠性为中等，但最小可检测变化过高。另一方面，评分者在 CMAS 工具的大多数项目上表现出显著的、中等至良好的内部评分者可靠性。然而，观察者在评估工具的大多数检查点时，可靠性并不显著。因此，建议为该工具提供更客观的指导方针和更清晰的每个标准定义，并为新观察者提供更长、标准化的培训期，以提高该工具在女性足球运动员应用环境中的可靠性。
