the current study aims to evaluate the reliability and repeatability of a new PT based on Center of Pressure (CoP) movement analysis in a repeated measures design.
the examination consisted of two parts: (1) the videotaping of General Movements (GMs) and GMs assessment (GMA) and (2) Posturometric Tests (PT) in supine and prone positions. PTs were performed twice (by two investigators) in the supine and prone positions using a force plate. Based on the GMA results, infants were stratified into two groups: (1) infants with normal FMs (indicating normal future motor outcomes) ( = 18) and (2) infants with abnormal FMs (indicating later neurological dysfunction) ( = 19).
the comparative analysis between the groups of infants with normal FMs and abnormal FMs in PT in supine showed significant differences for all parameters that described spontaneous CoP displacement. The reliability analysis determined that all ICCs of the outcomes presented at least a moderate level of reliability. The ICCs were higher for outcomes of PT performed in the supine position than in the prone position. The ICCs were higher for outcomes of PT performed in infants with abnormal vs. normal FMs.
although the current study yielded promising results, further longitudinal research in preterm infants should identify whether altered postural control parameters prognose future motor outcomes.
本研究旨在评估一种新的基于压力中心（CoP）运动分析的 PT 在重复测量设计中的可靠性和可重复性。
检查包括两部分：（1）GMs 录像和 GMs 评估（GMA）和（2）仰卧位和俯卧位的姿势测试（PT）。PT 在仰卧位和俯卧位使用力板进行两次（由两名研究人员进行）。根据 GMA 结果，将婴儿分为两组：（1）具有正常 FM 的婴儿（表示未来运动结果正常）（=18）和（2）具有异常 FM 的婴儿（表示以后有神经功能障碍）（=19）。
在仰卧位 PT 中，正常 FM 组和异常 FM 组婴儿的比较分析显示，所有描述自发性 CoP 位移的参数均存在显著差异。可靠性分析确定，所有结果的 ICC 至少具有中度可靠性。仰卧位 PT 结果的 ICC 高于俯卧位 PT 结果的 ICC。异常 FM 组婴儿 PT 结果的 ICC 高于正常 FM 组婴儿的 ICC。
尽管本研究取得了有希望的结果，但进一步对早产儿的纵向研究应确定姿势控制参数的改变是否预示未来的运动结果。
