Like many physiologic processes, Time of Day may influence postural control and gait. A better understanding of diurnal variations in postural control and gait may help to improve diagnoses, reduce falls, and optimize rehabilitation and training routines. This review summarizes the current literature that addresses these questions.
Does time of day affect postural control and gait?
We searched PubMed, Google Scholar, and IEEE using a combination of keyword and MeSH terms. We included papers that studied human subjects and assessed gait or postural control as a function of time of day. We evaluated the quality of the identified papers based on nine assessment criteria and analyzed them considering the topic (postural control or gait), age, and characteristics of the conducted assessments. We then quantitatively synthesized the results across studies using a meta-analytical approach (i.e., Hedges' g model).
Twenty-two papers considered the relationship between time of day and postural control, and eleven considered the relationship between time of day and gait. Six studies found that postural control was best in the morning, four described postural control being best in the afternoon, four described optimal postural control in the evening, and eight reported no time of day effect. Two studies found gait best in the morning, five described gait best in the afternoon, two described optimal gait in the evening, and two reported no time of day effect. The results of the quantitative analysis suggest that both postural control and gait were best in the evening.
While there is no clear consensus on whether there is a time of day effect for postural control and gait, the findings of this review provide initial evidence suggesting that a small but statistically significant effect exists in favor of the evening. Standardized testing, including repeated and continuous evaluations, may help provide more definitive information on time of day influences on postural control and gait.
像许多生理过程一样，时间可能会影响姿势控制和步态。更好地了解姿势控制和步态的昼夜变化可能有助于改善诊断、减少跌倒，并优化康复和训练计划。本综述总结了目前关于这些问题的文献。
时间是否会影响姿势控制和步态？
我们使用关键词和 MeSH 术语的组合在 PubMed、Google Scholar 和 IEEE 上进行了搜索。我们纳入了研究人类受试者并根据时间评估步态或姿势控制的论文。我们根据九个评估标准评估了确定论文的质量，并根据主题（姿势控制或步态）、年龄和进行的评估特征对其进行了分析。然后，我们使用元分析方法（即 Hedges'g 模型）对研究结果进行了定量综合。
22 篇论文考虑了时间与姿势控制之间的关系，11 篇论文考虑了时间与步态之间的关系。六项研究发现姿势控制在早上最佳，四项描述下午姿势控制最佳，四项描述晚上姿势控制最佳，八项报告无时间影响。两项研究发现步态在早上最佳，五项描述下午步态最佳，两项描述晚上步态最佳，两项报告无时间影响。定量分析的结果表明，姿势控制和步态在晚上都最佳。
虽然对于姿势控制和步态是否存在时间影响尚无明确共识，但本综述的结果提供了初步证据，表明存在有利于晚上的微小但具有统计学意义的影响。标准化测试，包括重复和连续评估，可能有助于提供关于时间对姿势控制和步态影响的更明确信息。
