Introduction: Working memory deficit is one of the most common complaints in post-stroke patients. The present study aimed to investigate the efficacy of the con-commitment use of unihemispheric concurrent dual-site a-tDCS (a-tDCSUHCDS), computer-assisted cognitive rehabilitation and conventional (Single site) a-tDCS in comparison with computer-assisted cognitive rehabilitation without tDCS on the working memory in stroke patients. Method:32 participants (21 males and11 females; age range 40-65years) with subacute stroke were selected by purposeful sampling method & randomly assigned to three experimental conditions and a controlled group with sham stimulation. All groups completed sessions of the Dual N-back training task. A-tDCSUHCDS group received anodal tDCS over the left DLPFC and M1 and conventional (Single site) a-tDCS group received anodal tDCS over the left DLPFC. Result: A repeated measures analysis of variance revealed that the a-tDCSUHCDS group had the larger improvement in working memory tasks after the intervention. Also, at the 8-weeks follow-up, the a-tDCSUHCDS group still had larger improvements in mentioned tasks. Conclusion: These results indicated that there may be potential for the concomitant use of a-tDCSUHCDS and computer-assisted cognitive rehabilitation by increasing the excitability of the cortical network of brain regions that play an important role in executive functions, to enhance the efficiency of the cognitive rehabilitation programs of the stroke patients.

Aim: Nowadays stroke is one of the most common disabling neurological diseases in the world. Cognitive complications are common problems in people with stroke. So the aim of this study was to evaluate the effect of computer-based cognitive rehabilitation on working memory function in the patients with stroke. Method: The present study is a quasi- experimental investigation using a pretest- posttest design and a control group. 30 stroke patients aged 30-65 who had the inclusion criteria, were randomly assigned to experimental and control groups. Experimental group trained for 21 sessions with Captain’s Log Cognitive Rehabilitation Software and control group did not receive any intervention. Wechsler working Memory Test (Number Memory Scale) and Cambridge Spatial Working Memory Test was applied at pretest and posttest. Findings: The results of ANCOVA analysis indicated that a significant difference between the means of working memory in experimental and control groups. Conclusion: Our findings indicated that computer-based cognitive rehabilitation improved working memory in people with stroke and it can be used as an effective and helpful method to improve memory performance of these patients.
