Cognitive decline after stroke is a common sequela and is highly associated with functional disability. Empirical evidence shows that exercise combined cognitive training may induce neuroplastic changes that modulate cognitive function. However, evidence about the effects of combined exercise-cognitive trainings on physiological biomarkers, cognitive and physical functions in stroke patients with cognitive decline is still less. The present study aim to investigate the effects of sequential combination of exercise-cognitive trainings on cognitive, physical, and daily function. In addition, the physiological mechanism of the combination training on cognitive function by several biomarkers including the brain-derived neurotrophic factor (BDNF), antioxidative marker, HbA1c, and plasma lipid level will be investigated. This study is a single-blind randomized controlled trial. Participants will be randomly assigned to SEQ group in which sequentially perform physical exercise and cognitive training or to CI group of control intervention.

The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS) is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0.
