Effectiveness Of Computer-assisted Working Memory Training For Patients With Cognitive Function Impairment After Stroke

Objective: To investigate the effect of computer-assisted working memory training for patients with cognitive function impairment after stroke.Methods: According to the inclusion criteria sixty-nine stroke patients with cognitive function impairment were randomly divided into three groups: control group(23), manual group(23), and video group(23). All patients received traditional rehabilitation training, besides, the manual group received manual working memory training and the video group received computer-assisted working memory training once a day which sustained 30 minutes, five days a week for four weeks. The Montreal cognitive assessment(Mo CA) was used to evaluate the cognition function of the subjects at the beginning and the end of the training, as well as 30 days and 90 days after the training.Results: 1. The executive function, attentive ability, memory ability, and total table points scores of manual group and video group were higher than the scores of control group and before the training at the end of the training, 30 days and 90 days after the training(P<0.05); In addition, the scores of the video group is higher than that of manual group(P<0.05).2. The verbal ability scores of video group were higher than manual group and control group at the end of the training, 30 days and 90 days after the training(P<0.05).3. The total table points scores of control group before the training were higher than the scores at the end of the training and 30 days after the training(P<0.05).Conclusion: Computer-assisted working memory training can obviously improve the executive function, attentive ability,memory ability and verbal ability of the patients with cognitive function impairment after stroke, and is superior to the traditional manual training.
