认知和步态障碍是帕金森病（PD）的常见症状。运动-认知双重任务（DTs）用于研究步态与认知之间的相互作用。然而，目前尚不清楚DT步态表现是否表明认知障碍。因此，本研究的目的是探讨认知缺陷是否通过时空步态参数的DT成本反映出来。方法：对67例PD患者的认知功能、单任务（ST）和DT步态表现进行研究。认知通过蒙特利尔认知评估（MoCA）进行评估，随后进行标准化的基于传感器的步态测试和相同的步态测试，同时减去一系列3。认知障碍由MoCA评分定义
Introduction: Cognitive and gait deficits are common symptoms in Parkinson's disease (PD). Motor-cognitive dual tasks (DTs) are used to explore the interplay between gait and cognition. However, it is unclear if DT gait performance is indicative for cognitive impairment. Therefore, the aim of this study was to investigate if cognitive deficits are reflected by DT costs of spatiotemporal gait parameters.Methods: Cognitive function, single task (ST) and DT gait performance were investigated in 67 PD patients. Cognition was assessed by the Montreal Cognitive Assessment (MoCA) followed by a standardized, sensor-based gait test and the identical gait test while subtracting serial 3's. Cognitive impairment was defined by a MoCA score
