About this trial

This is an interventional treatment trial for Stroke

Eligibility Criteria

18 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria

  • Subjects who have diagnosed as primary stroke by physician's physical exam or radiologic diagnosis
  • Subjects who have cortical or subcortical brain lesion
  • Subjects ages older than 18years old
  • Subjects who have 19 of K-MMSE score
  • Subjects who has unilateral neglect with BIT-C less than 129
  • Subjects who understand the purpose of the study and acquired the consent of the patient or caregiver

Experimental

Experimental

No Intervention

Arm Label

Pre-tDCS group

Simultaneous tDCS group

Sham control group

Arm Description

In Pre-tDCS group, total sessions of the transcranical direct current stimulator stimulation(tDCS) was done for each three subgroups and visual inattention training was followed after that. Patient had 2 times of tDCS for 13 minutes with 20minutes of resting interval. After that, additional 2 times of Visual inattention training was done with same protocol.

In Simultaneous transcranical direct current stimulator(tDCS) group, tDCS and visual inattention training was done simultaneously.

without transcranical direct current stimulator(tDCS) or without visual training

5. Study Description

Brief Summary
The primary objective of this study is to confirm and compare the effect of methods of transcranial direct current stimulation(tDCS) in the unilateral neglect of stroke patients
Detailed Description
Total 105 patients were recruited and randomized to receive either real or sham-tDCS. Real experimental groups were divided into two types; Pre-tDCS group and Simultaneous tDCS group. Two groups are again divided into three groups; Dual stimulation group, Unilateral stimulation group and Sham control group, respectively. In Pre-tDCS group, total a sessions of the tDCS stimulation was done for each three subgroups and visual inattention training was followed after that. In Simultaneous tDCS group, tDCS and visual inattention training was done simultaneously. For each subgroups, tDCS was attached at following locations; unilateral cathodal tDCS on unaffected PPC(postparietal cortex), P3 , dual cathodal tDCS on P3 and anodal tDCS on affected PPC, P4. The patients were initially evaluated at baseline, immediately, 60min, 120min, 24 hrs after the training session.
