Cognitive deficit following traumatic brain injury is one of the important consequences affecting the individual's quality of life. Various cognitive intervention strategies are in practice and the use of technology-based cognitive interventions are into current practice. This study is a Pilot Randomized Control Trial which aims to compare the effect of receiving the technology-based training along with the conventional therapy to the conventional therapy alone on executive functions among people with traumatic brain injury with mild to moderate cognitive deficit. This study will be done in Qatar Rehabilitation Institute, Hamad Medical Corporation, Doha, Qatar. People with traumatic brain injury with mild to moderate cognitive deficit (MMSE\>10 and \<23), between the age group of 18 to 60 years, no previous history of head trauma and willing to comply with cognitive rehabilitation program will be recruited for this study. The investigators will be explaining the details of the study to the participants and the participants who are willing to take part in the study had to give their consent by signing the consent sheet. After which they will be randomized in either intervention or control group through envelop concealment method. After randomization, the participants will be assessed using the outcome measures such as MMSE, Cognitive FIM and Executive function performance test (EFPT), one day before the start of the intervention. Participants in the intervention group will be receiving extra 45 min of technology based cognitive circuit training using MYRO, BITS and Cognitive Rehametrics in addition to the conventional therapy and participants in the control group will be receiving the regular conventional therapy alone. As a part of conventional therapy, participants will be receiving an hour of occupational therapy which focuses on all aspects of the deficit. For cognitive deficit, the participants will be receiving traditional method of training that includes paper pencil task, tabletop activities, performance-based activities and computer-based activities. Participants in both the groups will be receiving the sessions 5 times a week for 6 weeks. At the end of 6 weeks, all the participants in both groups will be assessed using the outcome measures, and the data will be collated, coded and entered in an excel sheet. The coded data will be sent for the statistical analysis.

Baseline characteristics will be presented as means±SD or median for continuous data, and as frequencies and associated percentages for categorical parameters. The statistical P value for change from baseline for quantitative outcomes will be calculated with a paired test or Wilcoxon signed rank test, and the P value for the difference between intervention and control groups will be calculated using unpaired t or Mann Whitney U tests appropriate.

Associations between two or more qualitative variables will be assessed using Chi-square (χ2) or Fisher Exact tests as appropriate. Relationship between two quantitative variables (age, EFPT, FIM scores etc.) will be examined using Pearson's or Spearman's correlation coefficients. All primary efficacy analyses will be performed on the intent-to-treat (ITT) population.
