PRIMARY OBJECTIVE: To assess a rehabilitation programme of working memory. RESEARCH DESIGN: Single case multiple-baseline-across-behaviour design in a patient with chronic stroke suffering from a specific impairment of working memory. METHODS: Rehabilitation included training of storage and processing components of verbal working memory. Outcome was assessed with specific working memory tests, non-specific tasks requiring working memory, non-target tasks not requiring working memory and questionnaires addressing daily-life functioning. This assessment was performed twice before the experimental therapy and once after. RESULTS: Cognitive measures were stable before therapy. A statistically significant improvement was found for target measures and for daily-life skills. In contrast, no change was found on non-target tasks. CONCLUSION: Improvement was not apparently related to spontaneous recovery, since performance was stable before therapy. This study suggests that specific cognitive training may improve working memory in patients with brain injury.

Vallat et al. (2005) conducted a case report in Chronic left hemisphere stroke with verbal working memory impairment (n=1). Verbal working memory rehabilitation programme (training of storage and processing components) vs. Pre-therapy baseline performance and non-target tasks was evaluated on Working memory tests and daily-life functioning questionnaires. Verbal working memory rehabilitation significantly improved target working memory measures and daily-life skills in 1 chronic stroke patient, with no change on non-target tasks.
