Researchers are studying how noninvasive brain stimulation using a device called HD-tDCS that delivers a weak electric current to the brain can help in improving hand functions in stroke patients.
Participants will have an MRI scan followed by magnetic brain stimulation using TMS, a device that uses a magnetic pulse to stimulate and locate the area of the brain that controls movement of the weak hand and fingers.
During visits 3 and 4, participants will play a computer game called MusicGlove. During these sessions, participants are fitted with a special cap that looks like a swimmer's cap that contains electrodes that can deliver low level direct current electrical stimulation (HD-tDCS) to the brain.
Participation lasts approximately 2-3 weeks, including 4 visits (first visit lasts 1.5 hours and the next 3 visits last 2-2.5 hours each).
- Individuals aged 18-75 years who have been clinically diagnosed with hemiparetic stroke (weakness on one side -either left or right side of the body).
- Stroke occurred at least 6 months ago.
- Have inadequate ability to move the fingers of the affected hand.
- Medically stable and not planning for major change in medications for at least 1 month.
Participants are compensated up to $130 for completing the study.
