Comparison of changes in cognitive functions of post-stroke patients with the computer-based cognitive intervention (PABLO system) and conventional cognitive intervention (Paper-Pencil method)
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. 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 computer-based cognitive intervention (CBCI) using PABLO system and conventional cognitive intervention (CCI) using paper-pencil method. Methods: Total 80 stroke patients with cognitive impairment were selected and divided into two groups. The Group A received intervention through PABLO System (CBCI) and the Group B received the cognitive intervention through 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 the groups were done by Addenbrooke Cognitive Examination-Revised (ACE-R) scale. Result: After the intervention of 4 weeks, patients of both groups showed improvement in cognitive functions. However, the group A scored higher in comparison to group B. Conclusion: Data suggest that both the interventions will bring the changes in cognitive functions post-stroke patients but CBCI may be much more effective in improving cognitive functions of stroke patients.
