建立线性和非线性测量的重测信度，包括会话内信度和会话间信度，用于分析脑瘫（CP）患儿坐位控制发展过程中的压力中心（COP）时间序列。纵向研究。大学医院实验室。有或有患CP风险的婴儿（N=18；入组时平均年龄±SD， 13.1.7±3.6个月）。不适用。连续4个月，每组3次试验（1周内每月2次）记录婴儿坐位COP数据。计算前后方向和中外侧方向的均方根、摆动范围和摆动路径的线性COP参数。此外，还计算了近似熵的非线性参数、Lyapunov指数（LyE）和两个方向的相关维数。通过类内相关系数（ICC）计算会话内和会话间的信度。在非线性测量方面，与所有其他评估参数相比，LyE显示出较高的会话内和会话间ICC值。在数据收集的最后2个月里，随着坐姿的改善，疗程内和疗程间的可靠性总体上有所提高。我们的研究结果表明，所提出的方法是一种可靠的方法来检查患有或有CP风险的婴儿坐姿控制的发展，可靠性结果与典型婴儿坐姿行为的值大致相同。因此，该方法可能有助于检查针对运动发育迟缓婴儿推进坐姿控制的治疗方案的有效性。
To establish the test-retest reliability of linear and nonlinear measures, 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 in infants with or at risk for cerebral palsy (CP). Longitudinal study. University hospital laboratory. Infants with or at risk for CP (N=18; mean age at entry in the study ± SD, 13.1.7 ± 3.6mo). Not applicable. Infant sitting COP data was recorded for 3 trials at each session (2 sessions for each month within 1 week) for 4 consecutive months. The linear COP parameters of root mean square and range of sway for both the anterior-posterior and the medial-lateral directions, and sway path, were calculated. In addition, the nonlinear parameters of approximate entropy, Lyapunov exponent (LyE), and correlation dimension for both directions were also calculated. Intra-session and inter-session reliability was computed by the intraclass correlation coefficient (ICC). Regarding nonlinear measures, LyE showed high intra-session and inter-session ICC values in comparison to all other parameters evaluated. Intra-session and inter-session reliability increased overall in the last 2 months of the data collections and as sitting posture improved. Our results suggested that the methodology presented is reliable way of examining the development of sitting postural control in infants with or at risk for CP, and the reliability results generally parallels values found in sitting postural behavior in typical infants. Therefore, this methodology may be helpful in examining efficacy of therapy protocols directed at advancing sitting postural control in infants with motor developmental delays.
