摘要采用二维视频分析法对5名4-12岁正常儿童睡眠期的全身运动（GM）进行了研究。各类型GM的发生率均表现出明显的睡眠阶段依赖性。在四种GM类型中，GM-1（有轴向旋转的GM）是最常见的。GM-1的平均持续时间最长。总共有77.2%的GM-1开始于下巴肌肉的收缩，35%的总睡眠变化（tSC）与GM有关。转基因后共有5.6%的tSC转向更深阶段。进一步的评价是必要的，以了解转基因的生理机制。
Abstract Gross body movements (GM) during sleep, classified into four GM types by the involved parts of body, were evaluated using two‐dimensional video analysis in five normal children aged 4–12 years. The rate of occurrence of all GM types showed apparent sleep stage dependency. Among four GM types, GM‐1 (GM with axial rotation) was the most frequent. Averaged duration of GM‐1 was the longest. A total of 77.2% of GM‐1 started with the contraction of chin muscle and 35% of total sleep changes (tSC) were related to GM. A total of 5.6% of tSC following GM shifted to the deeper stage. Further evaluation is necessary in order to understand the physiological mechanism of GM.
