Introduction:

despite the high incidence of executive symptoms after suffering a Traumatic Brain Injury (TBI), few studies assess the effectiveness of programs to the rehabilitation of executive functions (EF).

Objective:

to assess the effect of a rehabilitation program on inhibition and working memory, in a patient with severe TBI.

Methods:

an AB design with follow-up was used with a computerized program of 15 sessions, offered three times a week. The program efficacy was evaluated by sampling two target behaviors during different phases (baseline, during, post-intervention and long-term) and with standardized tests of inhibition and working memory (pre and post-intervention).

Results:

visual analysis revealed an upward trajectory in inhibition and working memory, with greater stability in the immediate and long-term evaluations. However, these changes cannot be fully attributed to the program.

Conclusions:

the rehabilitation program improved the process of inhibition with minimal effects on working memory. The former suggests that the intervention looks promising as a specific cognitive intervention but not a global stimulation resource for executive functions. In this respect, single-case designs are a valuable resource to ensure rigorous monitoring of the application and evaluation of interventions and analyze their effectiveness.
