ABSTRACT

OBJECTIVES: To evaluate benefits and harms for computer based cognitive rehabilitation (CBCR) on working memory impairment after stroke. METHODS: PRISMA guidelines were followed. Four electronic databases were systematically searched: Embase, Pubmed/Medline, PsycInfo and Cochrane Library. Authors of relevant studies were contacted to detect unpublished data or articles not found by searching databases. SELECTION CRITERIA: Studies were eligible for inclusion in the systematic review if they 1) investigated the effects of CBCR on working memory after acquired brain injury in a patient sample which consisted of at least 50% stroke-patients, 2) it was possible to isolate the effects of CBCR-training by comparison to passive or active control groups, and 3) if the outcome assessment included a quantitative working memory outcome measure either isolated or as part of a general outcome measure. Included studies were further eligible for the meta-analysis if 1) they were conducted as a randomized controlled trial, 2) they included only stroke patients, and 3) the effects of CBCR on working memory could be isolated. RESULTS: Literature is limited and reported effects of CBCR on working memory after stroke are very heterogeneous. A meta-analysis was not performed as all studies used different measures of working memory. An additional analysis was performed in order to cautiously estimate the difference between the control interventions (whether passive or active) and CBCR interventions. The analysis revealed no meaningful differences in increase of working memory measures between control conditions and intervention conditions. However, this additional analysis should be interpreted with caution as it does not take the heterogeneity of outcome measures or the differences in sample sizes between studies into account. No harms were observed. CONCLUSION: There is insufficient evidence to conclude if CBCR is beneficial for patients with working memory deficits after stroke. SYSTEMATIC REVIEW NUMBER: This systematic review is registered in Prospero with registration ID: CRD42018087437.

ABSTRACT

OBJECTIVES: The purpose of this pilot study was to investigate the feasibility and effects of computer-based cognitive rehabilitation (CBCR) in patients with symptoms of visuospatial neglect or homonymous hemianopia in the subacute phase following stroke. METHOD: A randomized, controlled, unblinded cross-over design was completed with early versus late CBCR including 7 patients in the early intervention group (EI) and 7 patients in the late intervention group (LI). EI received CBCR training immediately after inclusion (m = 19 days after stroke onset) for 3 weeks and LI waited for 3 weeks after inclusion before receiving CBCR training for 3 weeks (m = 44 days after stroke onset). RESULTS: CBCR improved visuospatial symptoms after stroke significantly when administered early in the subacute phase after stroke. The same significant effect was not found when CBCR was administered later in the rehabilitation. The difference in the development of the EI and LI groups during the first 3 weeks was not significant, which could be due to a lack of statistical power. CBCR did not impact mental well-being negatively in any of the groups. In the LI group, the anticipation of CBCR seemed to have a positive impact of mental well-being. CONCLUSION: CBCR is feasible and has a positive effect on symptoms in patients with visuospatial symptoms in the subacute phase after stroke. The study was small and confirmation in larger samples with blinded outcome assessors is needed.
