Аннотация:Rehabilitation of patients with impaired monitoring as a component of executive functionsBackground and Aims: Impairments of executive functions are among the most common consequences of neurological disorders, yet rehabilitation efficacy remains limited. This study aimed to evaluate the impact of specialized neuropsychological training on the dynamics of monitoring as a component of executive functions in patients with brain lesions.Methods: The study involved 48 patients (mean age: 57.6 years) divided into experimental (n=25) and control (n=23) groups. Assessments included the Frontal Assessment Battery (FAB), Tower of London, Color-Word Interference Test, and Luria’s neuropsychological tests. All patients were assessed with primary and repeated diagnostics. The experimental group underwent a 4-session training program integrating metacognitive strategies, self-regulation techniques, and Galperin’s stage-by-stage mental action formation method. Non-parametric Wilcoxon signed-rank and Mann-Whitney tests were applied for analysis.Results: A composite monitoring index (Cronbach’s α=0.634) was derived from task-specific metrics. The Mann-Whitney test revealed differences between two groups in the monitoring index post-intervention (p<0.05), though the Wilcoxon test in the target group was non-significant. However, the experimental group showed significant improvements in specific monitoring indicators: reduced loosing of associations (p<0.05), error repetitions (p<0.05) and decreased rule violations (p<0.01). In addition, the total FAB score improved significantly in the target group (p<0.05).Conclusions: The training positively influenced monitoring dynamics, the effect was observed primarily at the group level, likely due to mechanism of intra-system restructuring of executive functions and formation of new mental action of selection and implementation of the solution. Study limitations (e.g., sample size) highlight the need for methodological refinements.
