Primary Outcome Measures
NameTimeMethod
National Institutes of Health Stroke Scale (NIHSS) Change From Baseline at Day 90Baseline and Day 90

The NIHSS is a systematic assessment tool that provides a quantitative measure of stroke-related neurologic deficit. Values range from 0 (no deficit) to 42 (dead).

Secondary Outcome Measures
NameTimeMethod
NIHSS Response >=4 at Day 90Baseline and Day 90

The NIHSS is a systematic assessment tool that provides a quantitative measure of stroke-related neurologic deficit. Values range from 0 (no deficit) to 42 (dead). NIHSS Response \>=4 is defined as a \>=4 change from baseline at Day 90.

NIHSS Change From Baseline at Day 30Baseline and Day 30

The NIHSS is a systematic assessment tool that provides a quantitative measure of stroke-related neurologic deficit. Values range from 0 (no deficit) to 42 (dead).

Modified Rankin Scale (mRS) Response <=2 at Day 90Day 90

The mRS measures the degree of disability or dependence in the daily activities of people who have suffered a stroke. The scale runs from 0 (perfect health without symptoms) to 6 (dead). mRS response \<=2 is defined as the mRS score \<=2 at Day 90.

Barthel Index at Day 90Day 90

The Barthel Index measures 10 activities of daily living and mobility. A score of 100 = is best (able to live at home with a degree of independence), 0 is worst.

Action Research Arm Test (ARAT) Change From Baseline at Day 90Baseline and Day 90

The ARAT assesses recovery of arm function following stroke through a series of subtests judging ability to grasp, grip, pinch, or move the arm; scores are on a scale; The total maximum (best) score is 57 and the total minimum (worst) score is 0.

Gait Velocity Test Change From Baseline at Day 90Baseline and Day 90

The Gait Velocity Test assesses ability to walk as measured by the time (seconds) it takes a patient to walk 10 meters.

Boston Naming Test (BNT) Change From Baseline at Day 90Baseline and Day 90

The BNT assesses impairment of language ability by asking patients to identify 20 different pictures each time the test is taken. A score of 20 is best, 0 is worst.

Line Cancellation Test Change From Baseline at Day 90Baseline and Day 90

The Line Cancellation Test detects the loss of awareness of one side of the body. A score of 0.00 (no units) is normal (patient favors neither right nor left side). A score of +1.00 indicates severe unawareness of the left side. A score of -1.00 indicates severe unawareness of the right side.

Trails A Test Change From Baseline at Day 90Baseline and Day 90

The Trails A test measures visual scanning, numeric sequencing, and visual-motor coordination; the test score is the time (seconds) required to connect 25 numbers (e.g., 1, 2, 3, 4...)

Trails B Test Change From Baseline at Day 90Baseline and Day 90

The Trails B test measures visual scanning, numeric sequencing, and visual-motor coordination; the test score is the time (seconds) required to connect 25 alpha numeric circles (e.g., 1, A, 2, B, 3, C, 4, D)

Geriatric Depression Scale at Day 90Day 90

The Geriatric Depression Scale is commonly used to assess depression in stroke patients of any age by asking 15 yes/no questions, and then scored. A score of 0 - 5 is normal, whereas a score of 6 -15 suggests depression.
