| Objective: To explore the effects of right parietal transcranial direct stimulation (tDCS) on the components in different referential framework of visuo-spatial neglect. Methods: A total of 20 visuo-spatial neglect patients were randomly divided into treatment group (n=10) and control group (n=10). Ten patients in treatment group received tDCS and conventional physical therapeutic interventions, and 10 patients in control group only received conventional physical therapeutic interventions. Both groups received behavioral cognitive tests before and after treatment for 2 weeks, including egocentric reference framework component (line bisection test) and allocentric reference framework component (gap detection test). Results: Two weeks after treatment, there were significant differences in the lateralized score of line bisection task and the score of wrong marked circle with left gap in treatment group before and after treatment, and between treatment group and control after treatment (all P<0.05), but there was no significant difference in control group before and after treatment. Conclusions: The anodal tDCS on the right posterior parietal cortex facilitated the improvement of behavioral performance of both egocentric and allocentric reference framework components in right hemispheric stroke patients with visuo-spatial neglect. |
