Motor activity of laboratory dogs was recorded for several weeks with an ambulatory monitoring device. The effect of 24 h sleep deprivation (SD) on motor activity during recovery was investigated. A clear rest-activity rhythm was established. The dogs exhibited a similar mean daily rest-activity pattern: rest occurred mainly in the dark; the animals were most active after light onset; activity increased during the last two dark hours; a rest period was found at noon and reduced activity during afternoon hours. There was a marked difference in total activity between individual dogs. Activity patterns varied as a function of the day of the week; this may have been a reflection of variations in the level of human activities in the laboratory. There was a significant reduction of motor activity during the 24-h period following SD. This was particularly evident in the first 6 h of the light period immediately following the deprivation. In addition, there was a significant increase in the number of episodes with activity less than or equal to 5 counts during recovery. The study confirms the possibility of measuring motor activity to assess compensatory mechanisms during recovery after SD. Sleep regulation, therefore, does not necessarily need to be exclusively examined by the invasive technique of EEG registration.
使用动态监测设备记录了实验犬数周的运动活动情况。研究了24小时睡眠剥夺（SD）对恢复期间运动活动的影响。建立了清晰的休息 - 活动节律。这些犬表现出相似的平均每日休息 - 活动模式：休息主要发生在黑暗中；动物在光照开始后最活跃；活动在最后两个黑暗小时内增加；中午有一个休息期，下午活动减少。个体犬之间的总活动量存在显著差异。活动模式随星期几而变化；这可能反映了实验室中人类活动水平的变化。在SD后的24小时内，运动活动显著减少。这在剥夺后紧接着的光照期的前6小时尤为明显。此外，恢复期间活动量小于或等于5次计数的发作次数显著增加。该研究证实了通过测量运动活动来评估SD后恢复期间代偿机制的可能性。因此，睡眠调节不一定需要仅通过脑电图记录的侵入性技术来检查。
