Background: Due to the fact that the disruption in executive functions following traumatic brain injury causes disruption in the lives of patients and those around them, studies have been conducted are looking for methods of rehabilitation that are cheaper and easier. In spite of many studies, due to the diversity of the components related to the existing methods and the diversity of neuropsychological explanations from the cognitive components and the diversity of injury symptoms, many studies are still being conducted in this field. Aim: Finding one of the effective ways to improve the cognitive status of patients after traumatic brain injury Methodology: The TBI patients of Shahid Rajaei Hospital in Shiraz city in 1401, among the patients who met the entry criteria, 30 people were randomly selected and randomly assigned to two experimental and control groups. Then, cognitive rehabilitation was done by computer with Rehacom software and at the same time, transcranial direct current stimulation with was performed for the experimental group and its effect on executive functions was investigated using n-back test and qEEG and compared with the control group. Conclusions: The intervention caused an increase in the relative power in the alpha and theta band in fp1, but no significant difference was seen between the experimental and control groups. It also caused an increase in the relative power in the alpha and theta bands in fp2, where a significant difference was seen between the experimental and control groups, which was associated with improvement in the experimental group performance in the n-back test was consistent. Thus, Cognitive rehabilitation using tDCS simultaneously with computerized cognitive training has been effective in improving executive functions in traumatic brain injury patients
