The Effectiveness of Sensorimotor Rehabilitation with Transcranial Direct Current Stimulation on Response Inhibition and Risk Taking in Gifted Adolescents with Oppositional Defiant Disorder

Abstract

The present study was conducted in determining the effectiveness of sensorimotor rehabilitation with transcranial direct current stimulation (tDCS) on response inhibition and risk taking in gifted adolescents with oppositional defiant disorder. The research method was semi-experimental with a pre-test-post-test design with a control group. The statistical population of this research was 12-18-year-old gifted boys with oppositional defiant disorder in Tehran in 2024, 30 of whom were selected as a sample size from the population by purposive sampling. For the experimental group, sensorimotor rehabilitation with tDCS, where anodic stimulation was placed on the left dorsolateral prefrontal cortex and cathodal stimulation was placed on the right dorsolateral prefrontal cortex. Adolescent behavioral problems scale, Moon and Sun Stroop test, and Barrett's balloon riskiness were used. The data were analyzed using univariate analysis of covariance test. The findings showed that there was a significant difference between the post-test of the two groups in response inhibition and risk-taking by controlling the effect of the pre-test. According to the results of this study, it can be claimed that this intervention leads improve response inhibition and risk-taking in gifted teenagers with oppositional defiant disorder.
