Details and patient eligibility


This is a device feasibility study, which will assess telerehabilitation in people with chronic stroke using a combination of noninvasive brain stimulation and finger tracking training. Telerehabilitation allows patients to train in their own home which also allows for longer training periods than what is currently allowed clinically. Noninvasive transcranial direct current stimulation (tDCS) uses two surface electrodes connected to a small battery that will be attached to the head. This will be used to modulate neuronal excitability. With sensors attached to fingers and the wrist, the patient will move the joints to track a target displayed on a screen. The combined treatment will be applied in two experiments. The first will be on 3 patients coming to our lab and the second on 3 patients in their home, both under supervision. We will integrate the two components and test the resulting and novel treatment system for technical feasibility, which will set the stage for future efficacy studies under federal grant support. We hypothesize that the developed system will be safe and feasible.

Full description

This study will assess the feasibility of a telerehabilitation protocol involving non-invasive brain stimulation. Therefore, the two arms of the study are 1) implementation of this protocol in a controlled laboratory setting and 2) implementation of this protocol in a patient's home, being set up by the patient but controlled remotely using a blue-tooth system by an investigator in a different location. The two arms of this study will occur successively with the first arm being completed with three patients followed by the second arm being completed with a second group of three patients.

Single Group Assignment


None (Open label)

6 participants in 2 patient groups

In-lab tDCS
Active Comparator group
Three people with chronic stroke will participate in finger tracking training while receiving transcranial direct current stimulation (tDCS) in a controlled laboratory environment with an investigator.
Device: Transcranial direct current stimulation (tDCS)
In-home tDCS
Experimental group
Three people with chronic stroke will participate in finger tracking training while receiving transcranial direct current stimulation (tDCS) in their own home. Patients will be taught how to use a blue-tooth enabled telerehabilitation module that is being controlled by an investigator in the lab on the University campus. For safety, an investigator will be in the home with each patient during tDCS use and finger tracking training but will only be supervising procedures.
Device: Transcranial direct current stimulation (tDCS)
