RCT
PEDro=5
N=40 |
Population: TBI; Artificial Intelligence Group (n=20): Mean GCS=10.25. Psychoeducational Group (n=20): Mean GCS=10.05.
Intervention: Patients were randomly assigned to 12 sessions of Artificial Intelligence Virtual Reality training (treatment) or a conventional psychoeducational program (control). Outcomes were assessed at 1, 3 and 6 mo.
Outcome Measures: Wisconsin Card Sorting Test–computer version 4 (WCST), Tower of London Test, Vocational Cognitive Rating Scale, Employment status. |
1. Participants in the treatment group performed better across all measures, but only WCST-errors (p=0.02) and WCST-conceptual level response (p<0.01) were statistically significant.
2. Both groups showed significant improvements in employment outcomes (p=0.04 and p=0.018, respectively), but there were no significant differences between groups.
3. The treatment group showed significant improvement in self-efficacy (p=0.018) from pre- to post-test but the control group did not. However, there was no significant difference between the two groups. |
