A Study on Brain Activity During Transcranial Direct Current Stimulation in Stroke Patients

A Study on Brain Activity During Transcranial Direct Current Stimulation for Improving Finger-Hand Function in Stroke Patients

The purpose of this study is to identify the characteristics of neural plasticity seen in stroke patients by measuring the changes in brain activity during stimulation using functional near-infrared spectroscopy (fNIRS) when applying transcranial direct current stimulation (tDCS) for the purpose of enhancing finger function.

Inclusion Criteria:

• Unilateral stroke patients
• Chronic patients over 6 months after onset
• Subcortical stroke
• Patients with the movement of fingers

Exclusion Criteria:

• History of psychiatric disease
• Significant other neurological diseases except for stroke
• Difficult to perform this experiment
• Patients with metal implants
• History of epilepsy
• Pregnancy
• Skin defect at the site of electrode attachment
