Details and patient eligibility

About

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.

Sex: All

Ages: 19 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Unilateral stroke patients
• Chronic patients over 6 months after onset
