The purpose of this study is to evaluate a cognitive-motor exercise on dual-task interference during dual-task ankle movement and the corresponding alterations of brain activity.
The prevalence rate of stroke increased by 106.0% (93.7-118.8) from 1990 to 2019 in China, and stroke burden is still severe. Community ambulation is an important factor that influences health-related quality of life after a stroke.In daily living, effective community ambulation requires the ability to maintain balance and walking function while engaging in other tasks that demand attentional resources simultaneously (i.e., dual-tasking). Increasing evidence has shown that stroke patients have more problems with dual-task balance and walking function than their age-matched able-bodied peers. stroke individuals were found to have more reduction in both the walking speed and cognitive recall than control group during walking with remembering a shopping list. Hence, since stroke victims must reintegrate into community, this kind of cognitive-motor interference needs to be thoroughly studied.

Enrollment
84
participants receive three 60-minute COGMOTION dual-task exercise sessions per week for six consecutive weeks.
participants receive 30-minute single motor tasks with 30-minute single cognitive tasks three times per week for six consecutive weeks.The cognitive and mobility exercises will be the same as those in the dual-task group, but they will be performed separately.
participants receive upper limb strengthening exercise for 30 minutes and flexibility exercises for 30 minutes three times per week for six consecutive weeks. The training is performed in sitting or standing position and no cognitive load will be added.
