Аннотация:Background and Aims: Executive dysfunctions are common outcomes after ABI. Task setting and task switching might be considered as concrete parameters of executive functions (EF). We aimed to create the training for patients with executive dysfunctions and assess the influence of it on these processes.
Methods: Patients (stroke = 42, TBI = 6) were randomly divided into experimental group (n = 25, mean age = 56.7), who underwent the 4-session group training of executive functions (based on EF model of Stuss D.T. et al. and Galperin’ system of planned stage-by-stage formation of mental actions) and control group (n = 23, mean age = 58.6). Investigation consisted of FAB, ToL, Color-word interference test and Switching between categories from D-KEFS, arithmetic task, TMT-B and carried out twice for both groups. In analysis were used specific metrics for task setting and task switching and general EF parameters.
Results: In experimental group was obtained decrease of common parameter of task setting (Cronbach’s Alpha = 0.625, w = 228, p = 0.04, effect size = 0.403), errors with self-correction in Stroop test (w = 192.5, p = 0.0016, effect size = 0.522), which were attributed to task setting and task switching respectively, and increase of general FAB score (w = 21.5, p = 0.0013, effect size = 0.642), which was associated with EF condition.
Conclusions: The training influenced task setting and task switching, but improvement could be observed not in every diagnostic task. We can assume that the training had common influence on executive functions rather than influence on these processes.
