ABSTRACT

Objective: The purpose of this study was to verify the effects of vibration stimulation on the unilateral neglect in patients after a stroke. Methods: A single-subject research method using multiple baselines across the individuals was employed in this study. All subjects who showed unilateral neglect caused by a stroke received vibration stimulation applied to their left forearm for 30 minutes per sessions. A total of 20 sessions were conducted. Their unilateral neglect was measured through a Line Bisection test and Albert’s test during each session, and the Catherine Bergego Scale was used to evaluate the degree of unilateral neglect based on the pre-and post-test on their daily life. The data were visually analyzed using graphs and a descriptive statistical analysis. Results: All subjects showed statistically significant improvements in the Line Bisection test and Albert’s test scores, and the Catherine Bergego Scale scores were improved post-test. Conclusions: The results of this study indicate that vibration stimulation has a positive effect on the unilateral neglect, and may be considered an alternative choice in clinical occupational therapy for reducing unilateral neglect.
