Background: The purpose of this study was to compare the effectiveness of Transcranial Direct Current Brain Stimulation (tDCS) and computer-based cognitive rehabilitation on improving impulsivity in children with attention deficit/ hyperactivity disorder.
Materials and Methods: The current research design was quesi-experiment with pre-test-post-test and control group. 60 children with attention deficit/ hyperactivity disorder were selected by purposeful sampling and randomly replaced in three groups: experiment 1, experiment 2, and control (20 people in each group). Data were collected using Connors Parent Rating Scale (1978), Raven's Progressive Matrices Test (2000) Test and Barrett's impulsivity questionnaire (1995). The subjects of the first experimental group received Transcranial Direct Current Brain Stimulation (tDCS) and second experimental group also received Captain Log's rehabilitation intervention. The control group did not receive any intervention.
Results: The results showed that there is a significant difference between the groups impulsivity (P<0.05). The experimental groups of transcranial direct current brain stimulation (tDCS) and computer-based cognitive rehabilitation had lower impulsivity compared to the control group. Also, by controlling the effect of the pre-test in the two experimental groups, there is significant difference between the two methods of transcranial direct current brain stimulation (tDCS) and computer-based cognitive rehabilitation (P<0.05).
Conclusion: According to the results, it can be said that the intervention of transcranial direct current brain stimulation (tDCS) and computer-based cognitive rehabilitation was effective in improving the impulsivity in children with attention deficit/ hyperactivity disorder. Therefore, both interventions can be used to improve the impulsivity in children with attention deficit/ hyperactivity disorder.

Introduction: Since the anxiety is one of the effective factors in athletes, The aim of this study was to evaluate the effectiveness transcranial direct current stimulation (tDCS) on reducing anxiety in Martial Athletes.Materials and Methods: The research method was semi-experimental with a pretest-posttest design and control group. The statistical population of the present study consisted of all Martial Athletes in Ardabil in 2022. 30 people were selected by available sampling method and randomly assigned in experimental and control group (15 people in each group). Transcranial direct current stimulation (tDCS) was implemented in 10 sessions, each session lasting 20 minutes, but the control group received no training. Data was collected using State-Trait Anxiety Questionnaire (Moritz, 1990), which were administered in two stages of pre-test and post-test. Data were analyzed using SPSS software and multivariate analysis of covariance (MANCOVA).Results: The results showed that there was a significant difference between the post-test scores of the experimental group compared to the control group. In other words, transcranial direct current stimulation (tDCS) led to a significant increase in the self-confidence scores and a significant decrease in the physical and cognitive anxiety scores of the athletes (P<0.05).Conclusion: According to the results of this study, the treatment of transcranial direct current stimulation is an effective intervention on reducing anxiety in Martial Athletes and is a suitable, low-cost and accessible way that athletes can use.
