虽然双任务步行与额外的认知任务可能会降低步行性能，但许多研究也表明，在双任务期间，步行性能会增加，特别是随着认知负荷的增加。然而，根据认知负荷的差异，导致双任务中姿势控制变化的神经机制尚不清楚。因此，本研究的目的是调查不同的认知负荷的神经控制的肌肉活动在双任务步行使用内和肌间的连贯性分析的影响。对18名健康青年进行了单任务（无认知负荷的正常步行）和双任务（注视数字和数字2-背任务）条件下的跑步机步行测量，并测量了对听觉刺激的反应时。在步行与数字2-回任务，步幅时间的变异性显着减少，在正常行走，反应时间显着延迟，在正常行走和步行与观看数字。在β频段（15-35 Hz），背指行走时胫前肌肌内相干性峰值显著高于注视指行走时。目前的研究结果表明，年轻人可以增加他们的中央共同神经驱动和减少他们的步行变异集中在认知任务在双任务步行。
While dual-task walking with additional cognitive tasks may decrease walking performance, many studies have also shown increases in walking performance during dual tasks, especially as cognitive load increases. However, the neural mechanisms that cause changes in postural control during dual tasks according to the difference in cognitive load remain unclear. Therefore, this study aimed to investigate the influence of different cognitive loads on the neural control of muscle activity during dual-task walking using intra- and intermuscular coherence analyses. Eighteen healthy young adults were subjected to treadmill walking measurements in a single-task condition (normal walking without cognitive load) and two dual-task conditions (watching digits and digit 2-back task) with the measurements of reaction time to auditory stimulation. During walking with the digit 2-back task, stride-time variability was significantly reduced compared to that during normal walking, and reaction time was significantly delayed compared to those during normal walking and walking with watching digits. The peak value of the tibialis anterior intramuscular coherence in the beta band (15–35 Hz) significantly increased during walking with the digit 2-back task than that during walking with watching digits. The present results suggest that young adults can increase their central common neural drive and decrease their walking variability for concentration on cognitive tasks during dual-task walking.
