Background: Cognitive functions are mental series of activities that allow us to
carry out any activity. The most important cognitive functions are orientation, attention,
memory, executive functions, language, and visuospatial skills. Cognitive impairment is a
prevalent consequence of stroke. The prognosis of stroke recovery can be estimated
through the severity of cognitive impairment. The objective of this research work was to
compare the changes in cognitive functions of post-stroke patients with the computerbased
cognitive intervention (CBCI) using the PABLO system and conventional cognitive
intervention (CCI) using the paper-pencil method.
Methods: A total of 80 stroke patients with cognitive impairment were selected and divided
into two groups. Group A received intervention through PABLO System (CBCI),
and Group B received the cognitive intervention through the Paper Pencil method (CCI).
Pre and post-assessment of cognitive functions like verbal fluency, language, orientation
and attention, memory, visuospatial, and mini-mental state examination for both groups
were done by Addenbrooke Cognitive Examination-revised (ACE-R) scale.
Results: After the intervention of 4 weeks, patients of both groups showed improvement
in cognitive functions. However, group A scored higher in comparison to group B.
Conclusion: Data suggest that both the interventions will bring changes in cognitive functions
of post-stroke patients, but CBCI may be much more effective in improving the cognitive
functions of stroke patients.
