Ambulant sleep polygrams were obtained from 14 normal subjects (9 boys and 5 girls) and from 3 boys with attention deficit disorder. The children were aged 8-12 years. Two consecutive nights were recorded with an eight-channel electroencephalographic (EEG) tape cassette recorder. The results were analyzed automatically by the Oxford Medilog 9000 Sleep Stager and by visual scoring from the Medilog Display Unit. Twenty-seven nights were analyzed; 7 nights were excluded because of electrode problems or other technical failures. The main sleep stage shifts and the length of sleep cycles as measured from the hypnogram of the automatic printout agreed well with corresponding values from our visual scoring. In the automatic scoring, rapid eye movement (REM) sleep time was shorter and slow wave sleep was longer than in the visual rating. This can be explained partly by specific properties of the EEG in this age group. The Oxford Medilog 9000 sleep stager can be used to survey sleep quality, but the results must be carefully checked visually. In cases of EEG pathology or sleep abnormalities in childhood it is doubtful if any time or labor is saved by using automatic scoring.
对14名正常受试者（9名男孩和5名女孩）以及3名患有注意力缺陷障碍的男孩进行了动态睡眠多导图记录。这些儿童年龄在8至12岁之间。使用八通道脑电图（EEG）盒式磁带记录器记录连续两个晚上的情况。结果由牛津Medilog 9000睡眠分期仪自动分析，并通过Medilog显示单元进行视觉评分。共分析了27个晚上；由于电极问题或其他技术故障，排除了7个晚上的数据。从自动打印输出的睡眠图测量的主要睡眠阶段转换和睡眠周期长度与我们视觉评分的相应值非常吻合。在自动评分中，快速眼动（REM）睡眠时间比视觉评分短，慢波睡眠时间比视觉评分长。这在一定程度上可以用该年龄组脑电图的特殊性质来解释。牛津Medilog 9000睡眠分期仪可用于评估睡眠质量，但结果必须仔细进行视觉检查。在儿童脑电图病理学或睡眠异常的情况下，使用自动评分是否能节省时间或人力值得怀疑。
