NCT04549753

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Changes in cortical activity using fNIRS signals during brain stimulation

    Cortical activities before and after brain stimulation sessions are compared.

    Baseline and about 10 days (immediately after brain stimulation sessions)

Secondary Outcomes (6)

  • Changes in motor evoked potential

    Baseline and about 10 days (immediately after brain stimulation sessions)

  • 9-hole pegboard test

    Baseline and about 10 days (immediately after brain stimulation sessions)

  • Grip & Tip pinch strength test

    Baseline and about 10 days (immediately after brain stimulation sessions)

  • Box & Block test

    Baseline and about 10 days (immediately after brain stimulation sessions)

  • Fugl-Meyer Assessment

    Baseline and about 10 days (immediately after brain stimulation sessions)

  • +1 more secondary outcomes
