It is widely accepted that sleep better facilitates the consolidation of motor memories than does a corresponding wake interval (King et al., 2017). However, no in-depth analysis of the various motor tasks and their relative sleep gain has been conducted so far. Therefore, the present meta-analysis considered 48 studies with a total of 53 sleep (n = 829) and 53 wake (n = 825) groups. An overall comparison between all sleep and wake groups resulted in a small effect for the relative sleep gain in motor memory consolidation (g = 0.43). While no subgroup differences were identified for differing designs, a small effect for the finger tapping task (g = 0.47) and a medium effect for the mirror tracing task (g = 0.62) were found. In summary, the meta-analysis substantiates that sleep generally benefits the consolidation of motor memories. However, to further our understanding of the mechanisms underlying this effect, examining certain task dimensions and their relative sleep gain would be a promising direction for future research.
人们普遍认为，与相应的清醒间隔相比，睡眠更有助于运动记忆的巩固（King等人，2017年）。然而，到目前为止，尚未对各种运动任务及其相对睡眠增益进行深入分析。因此，本荟萃分析纳入了48项研究，共有53个睡眠组（n = 829）和53个清醒组（n = 825）。所有睡眠组和清醒组之间的总体比较显示，运动记忆巩固中的相对睡眠增益有较小效应（g = 0.43）。虽然不同设计未发现亚组差异，但发现手指敲击任务有较小效应（g = 0.47），镜像追踪任务有中等效应（g = 0.62）。总之，荟萃分析证实睡眠通常有利于运动记忆的巩固。然而，为了进一步了解这种效应背后的机制，研究某些任务维度及其相对睡眠增益将是未来研究的一个有前景的方向。
