Introduction: Stroke survivors with right hemisphere damage exhibit specific working memory deficits, often manifested as difficulty recognizing visual targets during monitoring.
Objective: This study aims to evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) on working memory in stroke patients with
hemineglect.
Materials and Methods: This experimental study involved 60 stroke patients with hemiplegia, who were randomly divided into two groups: 30 in the rTMS (experimental) group and 30 in the sham group. Both groups received treatment with rTMS at 0.9 frequency, three times a week for 10 minutes over 15 sessions. In the sham group, the rTMS device was turned off after 30 seconds, leading participants to believe they were receiving real treatment.
Results: The results indicated a significant difference between the pre-test and post-test working memory components for both the experimental and sham groups (P≥0.05). Additionally, the post-test comparisons revealed significant differences between the experimental and sham groups in terms of correct answers, unanswered cases, and response time (P≥0.05). Moreover, within the experimental group, the difference between post-test and pre-test scores for correct answers and errors was also significant (P≥0.05).
Conclusion: This study provides preliminary evidence that rTMS effectively enhances working memory in stroke patients with hemineglect, contributing to the expanding research on non-invasive brain stimulation in neurorehabilitation and underscoring the necessity for further investigation.
