Stroke risk within 1 week 6% for scores 4-5, 12% for scores >5

Mean Score 2.8 for rt-PA and 3.3 for control : difference 0.5 mRS points*
Number needed to treat to improve by 1 point is 2*
Number needed to treat to improve by 1 or more points is 3**
Number needed to treat to make one patient more independent =5*

The probability of returning home decreases by 20% for each
day the patient is not mobilized
Dysphagic patients have impaired oral movements resulting in debris, pooled secretions and
