Noninvasive Dual-mode Stimulation Therapy for Neurorehabilitation in Post-stroke Cognitive Impairment
Investigation for Individualized Noninvasive Neuromodulation in Neurorehabilitation of Brain Disease: Longitudinal Study
Repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) has been used for the modulation of post-stroke cognitive impairment patients' cognitive function by altering the cortical excitability.
Recently, more challenging approaches, such as stimulation of two or more sites or use of dual modality have been studied in stroke patients. In this study, simultaneous stimulation using both facilitatory rTMS (10Hz) and anodal or cathodal tDCS (dual-mode stimulation) over bilateral dorsolateral prefrontal cortices (DLPFCs) was investigated to compare its modulatory effects with single facilitatory rTMS stimulation in post-stroke cognitive impairment patients.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Anodal Dual-mode stimulation
10Hz of rTMS was applied over the left DLPFC for 10 minutes with simultaneous application of anodal tDCS on the right DLPFC. Each participant's 2-back verbal/nonverbal working memory task and variety cognitive function test are assessed and their resting-state fMRI data at three times: prior to stimulation (pre-stimulation), immediately after stimulation (post-stimulation) and 2 months after stimulation (f/u) are acquired. |
10Hz rTMS over the left DLPFC and anodal tDCS over the right DLPFC are simultaneously stimulated.
|
Experimental: Cathodal Dual-mode stimulation
10Hz of rTMS was applied over the left DLPFC for 10 minutes with simultaneous application of cathodal tDCS on the right DLPFC. Each participant's 2-back verbal/nonverbal working memory task and variety cognitive function test are assessed and their resting-state fMRI data at three times: prior to stimulation (pre-stimulation), immediately after stimulation (post-stimulation) and 2 months after stimulation (f/u) are acquired. |
10Hz rTMS over the left DLPFC and cathodal tDCS over the right DLPFC are simultaneously stimulated.
|
Active Comparator: Single sham stimulation
10Hz of rTMS was applied over the left DLPFC for 10 minutes with simultaneous application of tDCS with sham mode (no stimulation) on the right DLPFC. Each participant's 2-back verbal/nonverbal working memory task and variety cognitive function test are assessed and their resting-state fMRI data at three times: prior to stimulation (pre-stimulation), immediately after stimulation (post-stimulation) and 2 months after stimulation (f/u) are acquired. |
10Hz rTMS over the left DLPFC and sham tDCS (no stimulation) over the right DLPFC are simultaneously stimulated.
