- Brief Summary
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);
- Detailed Description
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.

Group Intervention Description Treatment Integrative tele-rehalitation of chronic stroke survivors using custom therapeutic games Participants will undergo 4 weeks (20 sessions) of experimental rehabilitation in their home. They will play custom therapeutic games that are intensive and adapt to their condition. Before and after the 4-week intervention participants will travel to Kessler Foundation to undergo evaluations. The therapy is designed to improve arm range, strength, endurance, as well as memory, focusing and decision making. Data will be stored on the cloud, protected and monitored by the research team.
- Primary Outcome Measures
Name Time Method Fugl-Meyer Assessment of Upper Extremity Function (Upper Extremity Sub-scale) Change from baseline at 4 weeks Upper Extremity motor function Sub-Scale: 0 (completely impaired) to 66 (normal).
Trail Making Test B (TMT-B) (raw score) measure of cognitive executive function Change from baseline at 4 weeks 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.
- Secondary Outcome Measures
Name Time Method Shoulder strength for deltoid muscles Change from baseline at 4 weeks 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.
Trail Making Test A (TMT-A) measure of visual and cognitive processing speed Change from baseline at 4 weeks Timed test measures the subject's Processing speed - visual and cognitive processing speed. Less time is better (1 second)
Upper extremity functional index (UEFI) self-report of independence in daily activities Change from baseline at 4 weeks 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).
Arm range of motion (degrees) measure for shoulder, elbow, wrist and fingers Change from baseline at 4 weeks 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)
Neuropsychological Assessment Battery NAB Verbal and Visual Attention Module Change from baseline at 4 weeks 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)
Brief Visuospatial Memory Test-Revised (Raw score) 4 weeks 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.
Subjective evaluation by participant of the experimental therapy 4 weeks Participant fills a custom questionnaire with 10 questions. Each question uses a 5-Point Likert scale the system ease of use, perceived benefits and technical issues. Scale (0: Strongly disagree, 4: Strongly agree. i.e., in favor of the system). Higher score is better. Maximum score if all are rated at strongly agree is 40.
Grasp strength for power grasps and pinch grasps Change from baseline at 4 weeks 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).
Boston Naming Test (short form) test of verbal abbility in name (noun) associations Change from baseline at 4 weeks 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
Blood Pressure measure by medical meter 4 weeks Blood pressure taken at each session (needs to be within physiological limits). Blood pressure is measured at start, mid and end of session.
Arm Reach Baseline (computer measure) 4 weeks Arm reach area (square inches) measured at start of session. Higher value of reach area is better.
Session duration (computer measure) 4 weeks Duration of exercises performed on the device during a session, measured in minutes by the computer. Minimum is 15 minutes, maximum is 40 minutes More is better.
Arm repetitions (computer measure) 4 weeks Computer measure of total arm repetitions done by the subject in the process of playing therapeutic games. The higher the number the better. Minimum is 0 meaning the subject had not mover either arm at all during the session.
Average game level of difficulty (Computer Measure) 4 weeks Computer measure of average game difficulty of all the games played by the subject in a give session. The higher the number the better. Minimum is 1 meaning the subject had played all the games at the lowest level of difficulty in that session. Maximum is 10 (all games were played at their highest level of difficulty).
Chedoke Arm and Hand Activity Inventory (CAHAI) 9 measure of independence in bimanual daily activities Change from baseline at 4 weeks 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.
Beck Depression Inventory II measure of depression severity Change from baseline at 4 weeks 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
Average game scores (computer measure) 4 weeks Average of scores achieved by a subjects when playing therapeutic games in a given session. The higher the average the better. Range is 1 (lowest difficulty) to 10 (highest difficulty).
Training intensity for arm and finger movements per minute (computer measure) 4 weeks Computer measure of average number of arm repetitions and of finger movements or grasps done by a participant in 1 minute in the process of playing therapeutic games. The higher the number the better. Minimum is 0 meaning the participant had not played at all (had no repetitions during that session).
Hopkins Verbal Learning Test, Revised (HVLT-R) measure of verbal, visual and memory Change from baseline at 4 weeks 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
Finger extension repetitions (computer measure) 4 weeks Computer measure of total finger extension repetitions done by the subject in the process of playing therapeutic games. The higher the number the better. Minimum is 0 meaning the subject had not opened either hand at all during the session.
Grasping repetitions (computer measure) 4 weeks Computer measure of total grasp repetitions done by the subject in the process of playing therapeutic games in a given session. When playing bimanually, the grasps by each hand are added in this measure. The higher the number the better. Minimum is 0 meaning the subject had not grasped at all during the session.
Pulse measure by medical meter 4 weeks Pulse taken at every session. Pulse is measured at start, mid and end of session.
Cognitive areas trained (computer measure) 4 weeks Computer measure of minutes of specific cognitive area training during a session. Specific domains are Attention, Memory, Executive Function and Language. Minimum is 0 (that area was not trained in a session).
