This study describes a protocol for the clinical assessment of dual motor task gait analysis in stroke patients with motor control deficits. The design of this protocol was based on two main points. First, most previous studies used a single walking task to assess the gait function of stroke patients, and the related discussions on motor control were inadequate, especially because the principles of complex motor movements were rarely involved22,23. Therefore, in ...

The restoration of independent walking function is one of the requisites for the participation of post-stroke patients in community life1. The recovery of walking ability requires not only the interaction of the perception and cognitive systems, but also motor control2,3,4. Furthermore, in real community life, people require higher abilities such as performing two or more tasks at the same time (e.g., walking while holding objects or crossing obstacles). Therefore, studies have begun to focus on the interference of dual-tasks in gait performance5,6. Previous dual-task studies were mostly targeted to elderly and cognitively impaired patients owing to the difficulty in motor performance and heterogeneity in stroke patients; the gait function in stroke patients was mostly evaluated by a single walking task7,8,9. However, further research on dual-task gait analysis, especially motor dual-tasks related to motor control, is required.
This study introduces a methodology for dual motor task gait analysis and evaluation. This protocol not only includes clinical assessment of the walking ability in stroke patients, but also focuses on two dual-motor tasks: the holding-water-and-walking task (a simple dual motor task) and the crossing-obstacle walking task (a complex dual motor task). The aim of this study was to explore the effects of dual motor tasks on the gait of stroke patients and to employ the dual-task gait cost (DTC) values10 of dual-task parameters (the difference between a single task and dual-task) to exclude the heterogeneity among stroke patients. The design of the experimental tasks facilitated an in-depth discussion of the motor control function of stroke patients, which provided new ideas for the clinical diagnosis and evaluation of the gait function of stroke patients.

motor dual-tasks for gait analysis and evaluation in post-stroke patients

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.

Eighteen patients with hemiplegia after stroke were recruited in this study. The average age of the participants was 51.61 &#177; 12.97 years; all were males. The proportion of left and right hemiplegia was 10/8; the average Brunnstrom stage was 4.50 &#177; 0.76. The average of MMSE and MoCA were 26.56 &#177; 1.67 and 20.06 &#177; 2.27, respectively. Other demographic characteristics (including stroke type and time of onset) are shown in Table 1. For the original data of gait dual-tasks (Task 1 and Task ...
