: Sleep quality is known to affect automatic and executive brain functions such as gait control and cognitive processing. This study aimed to investigate the effect of dual tasks on gait spatiotemporal parameters among young adults with good and poor sleep quality. : In total, 65 young adults with a mean age of 21.1 ± 2.5 were assessed for gait analysis during single-task and dual-task conditions. The participants' sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and gait was assessed using the BTS Gaitlab System. The participants were asked to walk at natural speed as a single-task condition, followed by walking while performing a cognitive task as a dual-task condition. The parameters assessed included the gait velocity (m/s), cadence (steps/min), step width (m), and stride length (m). The dual-task cost (DTC) on each gait parameter was calculated. The Mann-Whitney U test was used to compare the differences in the DTC on gait variables between the good and poor sleep quality groups and the Spearman correlation test was used to assess the correlation between total PSQI scores and the DTC. : At a significance level of < 0.05, a significant difference in cadence between the two sleep quality groups was observed, in addition to a positive correlation between sleep quality and the DTC effect on gait mean velocity, cadence, and stride length. Our findings also revealed a greater DTC in participants with poorer sleep quality. : These findings contribute to our perception of the significance of sleep quality in gait performance while multitasking in younger populations.
众所周知，睡眠质量会影响大脑的自动和执行功能，如步态控制和认知处理。本研究旨在调查双任务对睡眠质量良好和较差的年轻人步态时空参数的影响。
总共65名平均年龄为21.1±2.5岁的年轻人在单任务和双任务条件下接受了步态分析评估。使用匹兹堡睡眠质量指数（PSQI）评估参与者的睡眠质量，使用BTS步态实验室系统评估步态。要求参与者在单任务条件下以自然速度行走，然后在执行认知任务的同时行走作为双任务条件。评估的参数包括步态速度（米/秒）、步频（步/分钟）、步宽（米）和步幅长度（米）。计算每个步态参数的双任务成本（DTC）。使用曼-惠特尼U检验比较睡眠质量良好组和较差组之间步态变量的DTC差异，并使用斯皮尔曼相关性检验评估总PSQI分数与DTC之间的相关性。
在显著性水平<0.05时，观察到两个睡眠质量组之间的步频存在显著差异，此外，睡眠质量与DTC对步态平均速度、步频和步幅长度的影响之间存在正相关。我们的研究结果还显示，睡眠质量较差的参与者的DTC更大。
这些发现有助于我们认识到睡眠质量在年轻人群体多任务处理时步态表现中的重要性。
