Postural control (PC) can be affected by circadian rhythm and sleep deprivation, whereby it has been reported the result of PC measurement in clinical and experimental situations can be influenced by both factors. It has been suggested sleepiness can result in deficiency in PC, which in turn can lead to occupational accidents and subsequent injuries. This is while no study critically reviews or summarizes findings surrounding this topic in the literature.
Is there any significant effect of sleep deprivation and circadian rhythm on PC variables among healthy individuals?
PubMed, Web of Science, Scopus, and Embase were used to detect relevant studies. Only studies that examined the effect of time of day and/or sleep loss on PC among healthy individuals were included in this systematic review.
Forty-nine studies were included based on the inclusion criteria. Both circadian rhythm and sleep loss had a significant effect on PC, whereas there are inconsistent findings for optimal postural control regarding time of day. In terms of sleep deprivation, all investigations indicated that sleep loss deteriorates PC.
The current systematic review represents a significant effect of circadian rhythm and sleep deprivation on PC, whereby it is suggested that clinicians and researchers consider these factors when measuring PC since it may affect the result of research and clinical test. Moreover, PC may be worsened through sleeplessness; however, some studies revealed there is no linear relationship between time of wakefulness and deteriorating PC due to the influence of circadian rhythm. Hence, while PC, as an objective tool, can help to detect those who are sleep deprived, which in turn can lead to prevent possible musculoskeletal injuries, further studies are needed to reveal more understanding about the effect of sleep loss and circadian rhythm on PC.
姿势控制（PC）可能会受到昼夜节律和睡眠剥夺的影响，据报道，在临床和实验情况下，PC 测量的结果可能会受到这两个因素的影响。有研究表明，嗜睡会导致 PC 缺陷，进而导致职业事故和随后的伤害。然而，目前尚无研究对这一主题的文献进行批判性回顾或总结。
睡眠剥夺和昼夜节律对健康个体的 PC 变量是否有显著影响？
使用 PubMed、Web of Science、Scopus 和 Embase 检索相关研究。本系统评价仅纳入了研究昼夜节律和/或睡眠缺失对健康个体 PC 影响的研究。
根据纳入标准，共纳入 49 项研究。昼夜节律和睡眠缺失对 PC 均有显著影响，而关于一天中的最佳 PC 时间，研究结果并不一致。就睡眠剥夺而言，所有研究都表明，睡眠剥夺会降低 PC。
本系统评价代表了昼夜节律和睡眠剥夺对 PC 的显著影响，这表明临床医生和研究人员在测量 PC 时应考虑这些因素，因为这可能会影响研究和临床测试的结果。此外，由于昼夜节律的影响，失眠可能会使 PC 恶化；然而，一些研究表明，由于昼夜节律的影响，清醒时间与 PC 恶化之间没有线性关系。因此，虽然 PC 作为一种客观工具可以帮助检测那些睡眠不足的人，从而可以预防可能的肌肉骨骼损伤，但仍需要进一步的研究来揭示更多关于睡眠剥夺和昼夜节律对 PC 影响的理解。
