Objective: Study short- and long-term transfer effects of a computerized working memory (WM) training program for patients suffering from working memory deficits after acquired brain injury.
Methods: (Research design: A controlled experimental study with a crossover design.) The study group included a consecutive sample of 21 subjects. Mean age 43.2 years, time since injury/illness onset 37 months (median). The subjects were randomly selected into two groups where one group served as controls. All subjects trained five days a week for five weeks in a computer WM task program. They were followed-up at four and 20 weeks after the training.
Results: The study results showed a significant improvement in the trained WM tasks (p < 0.001), significant improvements in neuropsychological WM-test results at four and twenty weeks after training compared to baseline (p< 0.05). Results also showed a significant improvement in the subjects' rated level of occupational performance and satisfaction with performance in individually pre-defined occupational problems (p<0.05 for occupational performance versus p < 0.001 for satisfaction with performance) . Rated health-related quality of life did not change. However, rated overall health had significantly increased twenty weeks after training (p<0.05).
Conclusions: Structured and intense computerized WM training improves subjects' cognitive functioning as measured by neuropsychological WM-demanding tests, rated occupational performance, satisfaction with performance and rated overall health. The training probably has an impact on the rehabilitation outcome, returning to work, as well as on daily activities for individuals with verified WM impairments. We propose further research with a larger study group, including subgroups with different diagnoses, to confirm our current findings and select for whom this cognitive rehabilitation programme is most suitable.
