Stroke Clinical Trial
Official title:
Training Dual-task Balance and Walking in Community-dwelling Older Adults With Chronic Stroke: a Randomized Controlled Trial
Background Functional community ambulation not only requires a critical level of postural
control and walking skills, but also the ability to engage in cognitive tasks while walking
(i.e., dual-task walking) and adapt to the constantly-changing environmental contexts. There
is evidence showed that dual-task balance and gait performance is significantly impaired
after stroke. Increasing evidence also suggests that dual-task balance and gait performance
is useful for predicting falls among individuals with stroke. Considering the high clinical
relevance of dual-task balance and gait performance, it is essential that stroke
rehabilitation adequately addresses dual-task deficits. Developing specific dual-task
balance and gait training to enhance dual-task performance is thus necessary to promote
community ambulation and reintegration.
Study Aim The aim of this Introduction Many individuals after stroke continue to cope with
residual physical impairments after discharge from hospital. One of the major problems
encountered by people after stroke is community reintegration. Functional community
ambulation not only requires a critical level of postural control and walking skills, but
also the ability to engage in cognitive tasks while walking (i.e., dual-task walking) and
adapt to the constantly-changing environmental contexts. There has been an increasing
awareness of the importance of dual-task gait performance in community-dwelling individuals
with stroke in the past few years.

impaired after stroke. Increasing evidence also suggests that dual-task balance and gait

balance and gait training to enhance dual-task performance is thus necessary to promote

Study Aim This will be a single-blinded randomized controlled trial (RCT).The aim of this
study is to examine the efficacy of a dual-task exercise program on cognitive-motor
interference in balance and walking tasks, balance self-efficacy, participation in everyday
activities, community reintegration and incidence of falls among individuals with chronic
stroke.

Study design
This will be a single-blinded randomized controlled trial (RCT). After baseline evaluation,
subjects will be randomly allocated to one of the three groups: (1) dual-task training
group, (2) single-task training group, (3) strengthening and flexibility exercise group
(controls), using a 1:1:1 randomization sequence.
Measurements Outcomes will be used to compare the therapeutic effects of the 3 treatment
groups. The outcome measurements (except data on incidence of falls) will take place at 3
time points: (1) within one week before initiation of intervention (baseline), (2) within
one week after completion of training, (3) 8 weeks after completion of training. The fall
data will be collected on a monthly basis until 6 months after termination of the
intervention period. All assessments will be performed by a researcher who is blinded to
group allocation.
