Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purposes are to: (1) examine and compare the effects of two hybrid interventions on brain plasticity, physiological biomarkers and behavioral outcomes, including cognitive and physical functions, from pre- to post-training; (2) understand the neural mechanisms of cognitive recovery following two hybrid interventions using the functional magnetic resonance imaging (fMRI); (3) examine the long-term benefits of the two hybrid therapies; (4) to identify the correlations between brain activity, biomarkers and behavioral measures.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cognitive decline after stroke is highly associated with functional disability. Empirical evidence shows that exercise combined cognitive training may induce neuroplastic changes that modulate cognitive function. However, it is unclear whether hybridized exercise-cognitive trainings can facilitate cortical activity and physiological outcome measures and further influence on the cognitive function after stroke. We aim to investigate the effects of two hybridized exercise-cognitive trainings on brain plasticity, physiological biomarkers and behavioral outcomes in stroke survivors with cognitive decline. This study is a single-blind randomized controlled trial. A target sample size of 75 participants will be recruited. Stroke survivors with mild cognitive decline will be stratified by Mini-Mental State Examination scores and then randomized 1:1:1 to sequential exercise-cognitive training, dual-task exercise-cognitive training or control groups. All groups will undergo trainings 60 min/day, 3 days/week, for a total of 12 weeks. The primary outcome is the resting-state functional connectivity and neural activation in the frontal, parietal and occipital lobes in functional magnetic resonance imaging. Secondary outcomes include physiological biomarkers, cognitive functions, physical function, daily functions and quality of life.

This study may differentiate the effects of two hybridized trainings on cognitive function and health-related conditions and detect appropriate neurological and physiological indices to predict training effects. This study capitalizes on the groundwork for non-pharmacological intervention of cognitive decline after stroke.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Sequential training group

Exercise training for 30 minutes followed by 30 minutes of cognitive-based intervention

Group Type EXPERIMENTAL

Sequential training

Intervention Type BEHAVIORAL

The participant will cycle on a stationary bike for 30 minutes, which includes a 3-min warm-up phase followed by the aerobic training components (25 minutes), then a 2-min cool-down phase. The target heart rate during the aerobic training phase will be 40 to 70% of maximal heart rate (HRmax). After cycling, the participant will engage in a 30-minute of computer-based cognitive training program using BrainHQ (Posit Science Inc., San Francisco, CA, USA). The following are the areas of training: visuospatial processing, attention, memory, language, and logical thinking.

Dual training group

Exercise training simultaneously combined cognitive-based intervention for 60 minutes

Group Type EXPERIMENTAL

Dual training

Intervention Type BEHAVIORAL

The dual-task training group will cycling concurrently with the computer-based cognitive training. The training principle of cycling and cognitive training is similar to the SEQ group; however, the training intensity will be adjusted according to each participant's ability.

Control training group

non-aerobic exercise (e.g., stretch, range of motion exercise...) and unstructured cognitive rehabilitation programs (e.g., reading newspapers, playing board games...) for 60 minutes

Group Type ACTIVE_COMPARATOR

Control training

Intervention Type BEHAVIORAL

The control participants will receive 60 minutes of health-related rehabilitation programs which involves non-aerobic physical exercise (e.g., muscle stretching, range of motion exercises, relaxation techniques) and unstructured cognitive related rehabilitation programs (e.g., watch health-related videos or read newspapers or magazines and then answer the content-related questions raised by the therapist).
