Overview
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.
Description
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.
