The aim of the study is to develop the BrightBrainer G (grasp), a game-based upper-extremity motor and cognitive rehabilitation system using custom virtual reality simulations. The G model is a version of the BrightBrainer Rehabilitation System, a Class 1 Exempt medical device produced by Bright Cloud International Corp (FDA owner/operator 10050478), and listed with the FDA (registration number 3012187972);
8 elderly subjects (50 to 80 years old) who live at home and had a stroke more than 9 months prior to participation, who may also suffer from mild cognitive impairments and may be depressed, will be recruited. Their 8 caregivers will also be recruited at Kessler Foundation. Participants will train on the BrightBrainer system for 4 weeks in their home, doing a total of 20 rehabilitation sessions. Sessions will consist of playing therapeutic games using both the impaired and unimpaired arms. Sessions will progress in duration from 20 minutes to 40 minutes of actual play. Before and after the 4 weeks home therapy, participants will travel to the Kessler Foundation (West Orange, NJ) and undergo standardized motor, cognitive, and emotive clinical evaluations.

20 sessions of playing therapeutic games using both arms while siting at a table at home. Arms hold either generic game controllers, or BrightBrainer therapeutic controllers. Sessions involve a variety of games that train motor and cognitive function in an integrative way. The games are rendered by the BrightBrainer system. Games adapt and are winnable, benefiting well-being (reducing depression). Each session may generate many hundreds of arm repetitions, finger movement and grasps, depending on session duration. Data on arm reach as well as game outcomes and vitals are uploaded to an secure server. These data allow researchers to remotely monitor compliance to protocol and longitudinal progress. Caregivers are present at each session, and provide feedback as well as subjective ratings of the system.

Fugl-Meyer Assessment of Upper Extremity Function (Upper Extremity Sub-scale)
Upper Extremity motor function Sub-Scale: 0 (completely impaired) to 66 (normal).
Time frame: Change from baseline at 4 weeks
Trail Making Test B (TMT-B) (raw score) measure of cognitive executive function
Timed test measures the subject's executive function. Subject is asked to connect dots of a page (with associated digits) in increasing magnitude, in the shortest time. Less time (measured in seconds) is better.
Time frame: Change from baseline at 4 weeks
Upper extremity functional index (UEFI) self-report of independence in daily activities
Self-report of Independence in activities of daily living (ADLs). Scale: 0 (complete lack of independence in performing a given ADLs) to 80 (completely independent in that task). The form reports on 20 ADLs, which the highest score being 4 on each of them. Thus the highest possible score is 80 (20x4).
Time frame: Change from baseline at 4 weeks
Chedoke Arm and Hand Activity Inventory (CAHAI) 9 measure of independence in bimanual daily activities
ADL independence in bimanual tasks. Score Scale: 0 (completely impaired) to 63 (normal). Higher score is better, represented more independence in performing tasks with both hands.
Time frame: Change from baseline at 4 weeks
Arm range of motion (degrees) measure for shoulder, elbow, wrist and fingers
Measurement of active movement range for shoulder, elbow and fingers. Subjects' arm range of motion in each kinematic angles are measured in degree using a goniometer. Larger number is better (more range of motion)
Time frame: Change from baseline at 4 weeks

Shoulder strength for deltoid muscles
Measurement of shoulder strength using calibrated wrist weights. Subjects' shoulder strength is measured in pounds (lbs). More is better. 0 means no strength at all.
Time frame: Change from baseline at 4 weeks
Grasp strength for power grasps and pinch grasps
Grasp strength and pinch strength measurements using dynamo-meter and pinch meter. Three readings are used for the dynamometer when subject is asked to exert maximum power grasp, and then averaged. More is better. Minimum score is 0 (no strength at all).
Time frame: Change from baseline at 4 weeks
Neuropsychological Assessment Battery NAB Verbal and Visual Attention Module
Test for Verbal and visual attention will use Attention module digit span (working memory), dots (visual), which measures quantified metrics of subject's attention level. Dot test has a min of 0 (subject does not find the added dot) and a max of 12 (subject finds all added dots)
Time frame: Change from baseline at 4 weeks
Trail Making Test A (TMT-A) measure of visual and cognitive processing speed
Timed test measures the subject's Processing speed - visual and cognitive processing speed. Less time is better (1 second)
Time frame: Change from baseline at 4 weeks
Hopkins Verbal Learning Test, Revised (HVLT-R) measure of verbal, visual and memory
Tests measures the subject's verbal, visual and cognitive ability including delayed. Has 3 sub-tests plus a delayed recall test. Each sub-test has a min of 0 and a max of 12. Delayed recall has a min of 0 and a max of 24. More is better
Time frame: Change from baseline at 4 weeks
Boston Naming Test (short form) test of verbal abbility in name (noun) associations
Test measures subject's verbal and cognitive ability by asking specific questions. Min score 0 (unable to answer any of 15 questions) max score 15 (answers all). More is better
Time frame: Change from baseline at 4 weeks
Brief Visuospatial Memory Test-Revised (Raw score)
Timed Test of visuo-spatial memory by asking subjects to draw shapes they had seen. Higher score is better. Has alternate forms, only one form will be used in one evaluation.
Time frame: 4 weeks
Beck Depression Inventory II measure of depression severity
Depression severity score (0 min, 63 max, less is better). 0 normal, 1-13 minimal; 14-19 Mild Depression; 20-28 Moderate Depression; 29-63 Severe Depression
