Abstract

Abstract The availability of various motion capture systems provides researchers and clinicians options in collecting kinematic data. However, with electromagnetic tracking systems, it is imperative to determine the reliability of the system with regard to the specific movement of interest to ensure the collection of data that are reliable, interpretable and may be generalized to a broad spectrum of individuals. Thus, the purpose of this study was to establish the reliability of an electromagnetic tracking device (ETD) in analyzing young baseball pitchers. Two data collection sessions in which throwing kinematics were recorded were conducted across a five-day span. Joint kinematics were calculated using the standards and conventions recommended by the International Shoulder Group. Correlation analyses examining inter-day reliability of the ETD showed that the system was within acceptable limits (R > .73). Throughout the selected instances of the pitch cycle, the ETD used in the current study was shown to be reliable across multiple data collection session with ICCs ranging from R = .73 to R = .86. It appears so long as set-up, sensor attachment and digitization protocols remain consistent across data collection sessions, ETD’s are a reliable tool in analyzing throwing movements in younger participants.

电磁跟踪系统描述俯仰力学的可靠性
各种运动捕捉系统的可用性为研究人员和临床医生提供了收集运动学数据的选择。然而,对于电磁跟踪系统,必须确定系统在特定运动方面的可靠性,以确保收集的数据是可靠的、可解释的,并且可以推广到广泛的个人。因此,本研究的目的是建立电磁追踪装置(ETD)分析年轻棒球投手的可靠性。在为期五天的时间里,进行了两次数据收集,记录了投掷运动。使用国际肩关节组织推荐的标准和惯例计算关节运动学。对ETD日间可靠性的相关分析表明,该系统在可接受范围内(R = 0.73)。在选定的螺距周期实例中,本研究中使用的ETD在多个数据收集过程中是可靠的,ICCs范围为R = 0.73至R = 0.86。只要设置、传感器连接和数字化协议在数据收集过程中保持一致,ETD就可以成为分析年轻参与者投掷动作的可靠工具。
