Overview
Brief Summary
The focus of this study is to perform a preliminary assessment of the efficacy of the BurtVision system. While the Burt robotic-arm assists the patient's upper-limb in their movements, BurtVision will allow the patient to perform unimanual and bimanual activities while leveraging augmented reality games. The investigators will compare clinical outcomes when the BurtVisions ystem is used for training solely relying on unimanual tasks vs. when it is used for training relying on both unimanual and bimanual tasks.
Detailed Description
The proposed study is a single-blinded randomized clinical trial to evaluate the effect of using the BurtVistion on motor gains after robot-assisted upper-limb. Study participants (stroke survivors) will be recruited at the Spaulding Rehabilitation Hospital - Boston. Subjects will be randomly assigned to one of the two different groups: unimanual or unimanual + bimanual arm therapy using a block-randomized allocation procedure to ensure important covariates, such as baseline Fugl-Meyer Assessment of the Upper Extremity (FMA-UE) scores and chronicity, are balanced between groups.

Eligibility Criteria
Inclusion Criteria
- •Male or female, 18-80 years old;
- •Unilateral ischemic or hemorrhagic stroke at least 6 months and no more than 5 years prior to study enrollment;
- •Upper extremity hemiparesis as characterized by initial scores on upper limb subtest of the Fugl-Meyer Assessment (FMA-UE) between 12 and 40;
- •Some active pro-supination range of motion;
- •Some active metacarpal-phalangeal joint in the hemiparetic hand;
- •Intact cognitive function to understand the robotic therapy procedures (MMSE\>23 and able to follow 3 step command) during initial evaluation visit;
Exclusion Criteria
- •Undergoing upper-limb rehabilitation therapy during the period of the study.
- •Severe spasticity (defined as a Modified Ashworth scale score of 3 or more) that would prevent safe use of the robotic system;
- •Visual impairments as assessed by the NIH Stroke Scale Visual Field subscale (only subjects with no visual loss will participate in the study); or hemispatial neglect that would impair the subject's ability to play the interactive games (as assessed with the line bisection test);
- •Severe proprioceptive deficits that impair the ability to process haptic or visual feedback, as assessed by physical examination during screening;
- •Communication impairments such aphasia that impair the subject's ability of providing feedback (as reported by a physician in his/her medical record);
- •Individuals with open wounds or recent fracture (\<3 months) in the upper extremity, fragile skin or active infection;
- •Upper-extremity orthopedic injuries or severe pain resulting in movement limitations.
