Abstract
[Purpose] To investigate the effects of a combination of transcranial direct current
stimulation (tDCS) and feedback training (FT) on subacute stroke patients with unilateral
visuospatial neglect. [Subjects] The subjects were randomly assigned to a tDCS + FT group
(n=6) and a FT group (n=6). [Methods] Patients in the tDCS + FT group received tDCS for 20
minutes and then received FT for 30 minutes a day, 5 days a week for 3 weeks. The control
group received FT for 30 minutes a day, 5 days a week for 3 weeks. [Results] After the
intervention, both groups showed significant improvements in the Motor-Free Visual
Perception Test (MVPT), line bisection test (LBT), and modified Barthel index (MBI) over
the baseline results. The comparison of the two groups after the intervention revealed
that the rDCS + FT group showed more significant improvements in MVPT, LBT, and MBI.
[Conclusion] The results of this study suggest that tDCS combined with FT has a positive
effect on unilateral visuospatial neglect in patients with subacute stroke.
