Resumen

Background: Cognitive deficits following ischemic stroke significantly impair functional independence,
particularly in instrumental activities of daily living. Previous research highlights working memory as a
key target for rehabilitation, but the effectiveness of adaptive working memory training in improving
functional outcomes remains underexplored. This study draws on the theoretical framework linking
cognitive reserve and neuroplasticity to post-stroke recovery, hypothesizing that targeted cognitive
interventions can enhance both working memory and instrumental activities of daily living
performance.
Materials and Methods: A randomized controlled trial was conducted with 32 participants who
experienced ischemic stroke. Participants were randomly assigned to an intervention group (n=16),
receiving adaptive working memory training, or an active control group (n=16), engaged in nonadaptive cognitive activities. Independent variables included the type of intervention (adaptive vs.
standard), while dependent variables measured instrumental activities of daily living (Lawton-Brody
Scale) and working memory (Working Memory Questionnaire, Working Memory Index, Corsi Block
Tapping Test). The intervention entailed 25 sessions over 12 weeks, tailored to participant
performance to maximize cognitive engagement.
Results: The intervention group demonstrated a significant improvement in Working Memory Index
compared to the control group, suggesting a stronger effect of adaptive training on cognitive
outcomes. However, no significant differences were observed in instrumental activities of daily living
performance between groups, raising questions about the transferability of cognitive gains to
functional tasks.
Discussion: These findings support the theoretical premise that adaptive working memory training
enhances cognitive performance post-stroke but highlight limitations in its direct impact on functional
independence. Future research should explore the conditions under which such interventions
effectively translate cognitive improvements into practical gains, considering factors such as
intervention duration, intensity, and individual differences (e.g., baseline performance, motivation, and
genetic predispositions). The study underscores the need for refined intervention designs to bridge the
gap between cognitive training and functional rehabilitation outcomes.
