目的：确定线性和非线性工具在分析婴儿坐姿控制发展过程中压力中心(COP)时间序列时的可靠性，包括会话内和会话间的可靠性。纵向研究大学医院实验室33例典型发育婴儿(研究开始时的平均年龄±标准差，152.4±17.6d)。在研究的四个月中，不适用的婴儿在一周内接受了两次测试。在每届会议上记录了三次试验的现有缔约方会议数据(一周内每月两次)。计算均方根(RMS)的线性COP参数，前后(AP)和内侧(ML)方向的摇摆范围，以及摇摆路径。此外，还计算了两个方向的近似熵(ApEn)、Lyapunov指数(LYE)和关联维(CoD)等非线性参数。通过组内相关系数(ICC)量化会话内和会话间的可靠性。我们的结果表明，COP数据的评估是研究坐姿控制发展的可靠方法。特别是，与所有其他被评估的参数相比，ApEn的非线性工具显示出较高的会话内和会话间ICC值。一般来说，在数据收集的最后两个月，随着坐姿的成熟，会话内和会话间的可靠性都有所增加。本研究强调，在将COP作为一种检查干预进展的方法之前，有必要建立COP的可靠性，该方法旨在改善运动发育迟缓婴儿的坐姿能力。
To determine the reliability of linear and nonlinear tools, including intra- and inter-session reliability, when used to analyze the center of pressure (COP) time series during the development of infant sitting postural control. Longitudinal study University hospital laboratory Thirty three typically developing infants (mean age at entry in the study ± standard deviation, 152.4 ± 17.6 days). Not applicable Infants were tested twice in one week at each of the four months of the study. Sitting COP data was recorded for three trials at each session (two each month within one week). The linear COP parameters of root mean square (RMS) and range of sway for both the anterior-posterior (AP) and the medial-lateral (ML) directions, and the sway path, were calculated. In addition, the nonlinear parameters of approximate entropy (ApEn), Lyapunov exponent (LyE), and correlation dimension (CoD) for both directions were also calculated. Intra-session and inter-session reliability was quantified by the intraclass correlation coefficient(ICC). Our results showed that the evaluation of COP data is a reliable method of investigating the development of sitting postural control. In particular, the nonlinear tool of ApEn presented high intra- and inter- session ICC values in comparison to all other parameters evaluated. Generally, intra- and inter- session reliability increased in the last two months of the data collections and as sitting posture matured. The present study emphasizes the need for establishing COP reliability before using it as a method of examining intervention progress directed at improving the sitting postural abilities in infants with motor developmental delays.
