本研究招募了18名中风患者，包括认知和行走能力评估以及多任务步态分析。多任务步态分析包括单一行走任务（任务0）、简单运动双任务（任务1）和复杂运动双任务（任务2）。跨越障碍的任务被认为相当于简单的步行任务和复杂的运动任务的结合，因为它涉及更多的神经系统、骨骼运动和认知资源。为了消除脑卒中患者步态分析结果的异质性，计算了不同运动学参数的双任务步态成本值。主要的差异是在近端关节角度，特别是躯干、骨盆和髋关节的角度，在双运动任务中明显大于单一行走任务。本研究方案旨在通过双运动行走任务的分析，为脑卒中运动控制缺陷患者的步态功能的临床诊断和运动控制的深入研究提供依据。
Eighteen stroke patients were recruited for this study involving the evaluation of cognition and walking ability and multitask gait analysis. Multitask gait analysis consisted of a single walking task (Task 0), a simple motor dual-task (water-holding, Task 1), and a complex motor dual-task (crossing obstacles, Task 2). The task of crossing obstacles was considered to be equivalent to the combination of a simple walking task and a complex motor task as it involved more nervous system, skeletal movement, and cognitive resources. To eliminate heterogeneity in the results of the gait analysis of the stroke patients, the dual-task gait cost values were calculated for various kinematic parameters. The major differences were observed in the proximal joint angles, especially in the angles of the trunk, pelvis, and hip joints, which were significantly larger in the dual motor tasks than in the single walking task. This research protocol aims to provide a basis for the clinical diagnosis of gait function and an in-depth study of motor control in stroke patients with motor control deficits through the analyses of dual-motor walking tasks.
