A comparative study of the effectiveness of Non-computer and Computer-based Cognitive Rehabilitation Interventions on Auditory/Visual Working Memory of Stroke Patients

Abstract

Background. Given the fact that there is contradictory evidence regarding the effectiveness of computerized cognitive rehabilitation interventions, the present study intended to compare the potential effects of non-computer and computer-based cognitive rehabilitation interventions on the memory of stroke patients in Tabriz. Methods. To this end, we conducted a quasi-experimental study with a pretest-posttest control group design. The population of the study included individuals who were admitted to a hospital in Tabriz, Iran, for the treatment of stroke. After identifying patients who met the inclusion criteria on the base of purposive sampling,, 45 stroke patients were randomly selected and assigned to two experimental groups (15 in the computer-based group and 15 in the non-computer group) and one control group (15 in the waiting list). To measure the dependent variables of the research, Wechsler’s Digit Span subscale and Folstein’s MMSE were used. The cognitive rehabilitation therapy was performed three times a week for 7 weeks for the non-computer experimental group. The computer-based rehabilitation intervention using Captain’s Log software was delivered during the same period. Results. The results show that both computer-based and non-computer cognitive rehabilitation interventions are equally effective in improving working memory (visual and auditory) of stroke patients. Conclusion. It can be concluded that the unsubstantiated orientation towards the quality and quantity of using new computer-based interventions is not desirable and that the potential of both computer and non-computer interventions should be used to improve the memory of stroke patients. Practical Implications. Based on the findings, specialists can use the potential of both non-computer and computer-based cognitive rehabilitation interventions in improving auditory/visual working memory function of patients with stroke.
