    Results: Total Criteria Point Count:
    • * If an arm or leg cannot be tested due to amputation or other limitation, untestable is recorded and no points are counted.
    • NIH Stroke scores > 22 are considered very significant and may predict increased complication risk.
    • The score is commonly used to track outcomes, improvement or deterioration of a stroke.
