NCT02552368

Brief Summary

The ultimate goal of this project is to develop a functioning and clinically feasible method for restoring function to motor-impaired stroke survivors. This ultimate goal will be approached through two different means. The first method is to develop a functioning brain-computer interface that operates based on cortical activity ipsilateral to an intended movement on the motor-impaired side of the body. And secondly, to develop new methods of rehabilitation that involve stimulating peripheral muscles based upon cortical activity ipsilateral to intended movements. Finally, the study seeks to assess changes in functional connectivity as a result of using a BCI device.

Outcome Measures

Primary Outcomes (1)

  • Change in Action Research Arm Test (ARAT) Score

    The Action Research Arm Test (ARAT) is an evaluative measure to assess specific changes in limb function among individuals who sustained cortical damage resulting in hemiplegia (Lyle, 1981). It assesses a client's ability to handle objects differing in size, weight and shape and therefore can be considered to be an arm-specific measure of activity limitation (Platz, Pinkowski, Kim, di Bella, \& Johnson, 2005). The ARAT's is a 19 item measure divided into 4 sub-tests (grasp, grip, pinch, and gross arm movement). Performance on each item is rated on a 4-point ordinal scale ranging from: 3\) Performs test normally 2) Completes test, but takes abnormally long or has great difficulty 1\) Performs test partially 0) Can perform no part of test The maximum score achievable on this measure is 57 points.

Study Arms (1)

IpsiHand

EXPERIMENTAL

IpsiHand is a device which includes a robotic glove that you wear on your hand and a headset that you wear on your head. The headset picks up your thoughts and sends them to the robotic glove, to control opening and closing of your hand.

Device: IpsiHand Device

Interventions

Once a participant has completed (3) EEG Signal Screens and (2) separate set of baseline measurements, the IpsiHand BCI Device is provided to participants to use a minimum of (5) out of (7) days a week for a total duration of 12 weeks. Participants are seen bi-weekly throughout the duration of the trial to assess affected upper extremity and assess functional impact. At the completion of 12 weeks of device use, the participants complete a set of measurements to assess function of the affected upper extremity.
