Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This clinical RCT study intends to combined different forms of multi-channel tDCS with the routine cognitive training process to treat patients with post-stroke cognitive dysfunction.

The therapeutic effects among single-channel tDCS group, multi-channel tDCS and pseudo-multichannel tDCS group will be compared. Brain magnetic resonance mechanism research will also be included to reveal the possible mechanism of multi-channel tDCS technology for PSCI brain network.

Thus, the efficacy and mechanism of multi-channel tDCS in post-stroke cognitive function rehabilitation will be researched both in the clinical and basic levels.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

multi-channel tDCS

In the multi-channel tDCS stimulation group, a 1:4 (anode: cathode) approach was applied, with the central anode placed in the left dorsolateral prefrontal cortex (dlPFC) (reference 10-20 standard lead EEG), and the remaining cathode distributed around the central electrode.

The rising time and falling time of current are 30 seconds respectively. Stimulate 30 minutes daily for 10 days (Monday to Friday, once a day, weekend off).

Group Type EXPERIMENTAL

multi-channel tDCS

Intervention Type DEVICE

multi-channel transcranial direct current stimulation, tDCS

single-channel tDCS

The anode electrode of the single-channel tDCS stimulation group was placed in the left dlPFC, and the cathode electrode was placed in the right orbital forehead.

The rising time and falling time of current are 30 seconds respectively. Stimulate 30 minutes daily for 10 days (Monday to Friday, once a day, weekend off).

Intervention Type DEVICE

sham stimulation

The shame stimulation group had only 30 seconds of up and down stimulation, with no intermediate stimulation.
