All participants will receive treatment with the IpsiHand Device.

The IpsiHand system utilizes a Brain-Computer Interface (BCI) to enable operation of a robotic hand exoskeleton worn on the hand and wrist as participants are guided through a rehabilitation program on a tablet. Participants will complete 12 weeks of hometherapy with the IpsiHand system. Motor function of their impaired upper extremity will be evaluated at baseline, at 4-week intervals, and 12 weeks completion of IpsiHand use.

The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning and joint functioning in patients with post-stroke hemiplegia. It is applied clinically and in research to determine disease severity, describe motor recovery, and to plan and assess treatment. The FMA is a score on a scale of 0 to 66 points. A lower score indicates impaired motor function in the upper extremity assessed. A higher score on the scale indicates better motor function of the upper extremity. A score of 66 would indicate there is no motor function impairment of the upper extremity.

The Arm Motor Ability Test (AMAT is used to measure functional limitation in the upper extremity in rehabilitative trials enrolling individuals with stroke primarily. The measure requires clients to perform 28 common unilateral and bilateral UE tasks. Performance on each task is timed by the evaluator and rated by the evaluator using a 6-point Functional Ability Scale from 0 to 5. A score of 0 indicates no attempt moving the affected upper extremity in the task. A score of 5 indicates one is using their affected arm with full movement, normal. One can achieve a total a range of 0 points to 140 points

This study was a prospective, non-randomized, self-controlled study performed in two phases at two investigational sites. 17 chronic stroke survivors (6 months or more post stroke) utilized the BCI Neurolutions IpsiHand System (the "device") at home for 12 weeks. During this time, data was collected at baseline, during, and upon completion of use of the Neurolutions IpsiHand System.

IpsiHand is a device which includes a robotic exoskeleton that you wear on your forearm and hand, an EEG headset worn on your head, and a tablet which includes therapy software and guides you through daily therapy exercises.

Once a participant completes an initial EEG screening, the participant completes a set of baseline measurements, the IpsiHand BCI device is then provided to the participants and are to be used a minimum of 5 days a week out of 7 days , for a total duration of 12 weeks. Participants are seen monthly throughout the 12-week duration while they are using the IpsiHand. After completion of device use, participants were asked to be evaluated 6 months after discontinuation of the IpsiHand to assess durability effects.
