Rehabilitation interventions for cognitive deficits in stroke survivors: A systematic review of randomized controlled trials

cognitive deficits are one of the most common impairments after stroke. It negatively affects physical and social functioning. rehabilitation interventions for cognitive deficits post-stroke have taken less consideration. the present study aimed to provide an overview of the effects of various rehabilitation interventions on cognitive functions in patients with stroke. PUBMED, SCOPUS, PEDro, EMBASE, MEDLINE, and REHABDATA were searched for randomized controlled trials (RCTs) investigating the effects of rehabilitation interventions on cognitive domains poststroke until august 2021. the methodological quality of the selected studies was evaluated using the cochrane collaboration tool, and the effect sizes were calculated. forty-four studies met the inclusion criteria. a total of 3561 individuals with stroke, 57.60% of whom were males. the mean age for all participants was 65.48 years. eighteen RCTs were high, moderate (n = 17), and low methodological quality (n = 9). the results showed evidence for the beneficial effects of many rehabilitation interventions on cognition in individuals with stroke. rehabilitation plays a crucial role in improving cognitive functions in stroke patients with mild cognitive deficits. virtual reality (VR), computer-based cognitive rehabilitation (CBCR), and non-aerobic exercises may promote cognitive functions in patients with stroke.
