An interventional study of Dual-task training and Single-task training in Stroke, sponsored by The Hong Kong Polytechnic University. Completed at 1 site in Hong Kong. Open to participants aged 50 Years and older. Per ClinicalTrials.gov, last updated 2026-09-17.
Sponsored by The Hong Kong Polytechnic University · Not applicable, Interventional, and Treatment
To assess the effects of a dual-task exercise program on cognitive-motor interference during dual-task walking and the associated changes in brain activity.
Stroke is one of the leading causes of chronic disability in Hong Kong and other parts of the world. Mobility dysfunctions are among the most common impairments observed after stroke. Restoration of mobility is also a top priority in rehabilitation goal-setting by stroke patients. In daily life, functional ambulation in the community requires the ability to maintain walking balance while simultaneously engaging in other attention-demanding tasks (i.e., dual-tasking), such as walking when holding a conversation, or crossing the street while attending to traffic signals. There is increasing evidence that performing a cognitive task in conjunction with a mobility task would cause more severe degradation of one or both tasks among stroke patients when compared with age-matched able-bodied individuals. This phenomenon, termed "cognitive-motor interference", should warrant detailed study, since it has an important impact on community-living among people with stroke.
7,283 studies on the registry are indexed under Stroke; 2,013 are open to participants now.
This study's enrollment of 108 is above the median of 50 across 5,366 interventional studies indexed under Stroke.

Exclusion Criteria:
Mobility tasks performed in conjunction with cognitive tasks
Behavioral: Dual-task training
Separate cognitive and mobility exercises
Behavioral: Single-task training
Upper limb strengthening and flexibility exercises
Behavioral: Control group
This group will receive 30 min of dual-task exercise training and 30 min of stretching exercises in each session. The dual-task component involves walking activities performed in conjunction with cognitive activities. For the stretching exercise component, no cognitive load will be added.
This group will undergo 30 min of single-task mobility training and another 30 min of single-task cognitive activities. The cognitive and mobility exercises will be the same as those in the dual-task group, but they will be performed separately. No extra cognitive load will be imposed during the mobility exercises. No additional motor demand will be imposed during the cognitive exercises, as the participants will be sitting.
This group will undergo 30 min of stretching exercises (same as the dual-task group) and another 30 min of upper limb strengthening exercises performed primarily in the sitting or lying position. No cognitive load will be added.

Balance 1
Mini Balance Evaluation Systems Test will be used to assess postural control, with total points from 0-28. Higher points indicate better performance.
Time frame: Through study completion, an average of 1 year
Balance 2
Activities-specific Balance Confidence Scale will be used to assess confidence of functional balance performance, with total points from 0-100. Higher points indicate better performance.
Time frame: Through study completion, an average of 1 year
Single-task walking speed
10-meter walking test will be used to assess single-task walking speed in meters per second
Time frame: Through study completion, an average of 1 year
Cognitive performance 1
Digit Span Test will be used to assess working memory
Time frame: Through study completion, an average of 1 year
Cognitive performance 2
Montreal Cognitive Assessment will be used to assess global cognition, with total points from 0-30. Higher points indicate better performance.
Time frame: Through study completion, an average of 1 year
Fall incidence
Monthly telephone interviews for recording fall incidence
Time frame: Through study completion, an average of 1 year
