ABSTRACT: Objective: This study
aimed to
carry out a topographical analysis of frontal lobe executive function components
in post-stroke patients. Methods: A descriptive, cross-sectional
study. The assessment using the WCST (Wisconsin Card Sorting Test) included
sixteen patients with a clinical diagnosis of CVA and frontal lobe impairment. Results
from the two groups were compared (patients with right frontal lobe impairment
and patients with left frontal lobe impairment). Statistical analysis was
performed using the program “Statistical Package for Social Sciences” (SPSS) Version
20.0. For comparison between groups was used Mann-Whitney test and considered
the alpha level of 0.05 on the statistically significant results. Results: There was no
statistically significant difference between the groups, thus showing that
executive functions are symmetrically distributed across the frontal lobes. Conclusion: Executive functions
are symmetrically organized across the two frontal lobes, since the comparison between
the groups did not demonstrate a statistically significant difference for any of
the variables of WSCT.
