Earlier Mobilization Post Acute Thrombectomy

Study Overview
=================
Brief Summary
-----------------
This is a phase III trial trying to determine whether 12-hour bed rest following thrombectomy for ischemic stroke is non-inferior to 24-hour bed rest by measure of outcomes on the modified Rankin Scale (mRS) at 90 days post bed rest.

Eligibility Criteria
-----------------
Inclusion Criteria: Age 18 years or older Received thrombectomy (may have also received intravenous tPA) for a diagnosis of acute ischemic stroke TICI 2b/2c/3 score following thromectomy Patient and/or Legally Authorized Representative provide consent Exclusion Criteria: TICI 0/1/2a score following thrombectomy Venous thromboembolism present at symptom onset Pneumonia present at symptom onset STEMI at symptom onset Positive troponins at symptom onset according to local values Bone fracture at symptom onset Intubation anticipated or occurred Symptomatic intracranial hemorrhage (defined as increase in NIHSS by 4 points or more accompanied by PH2 hemorrhage on imaging) at the time of screening. Pre-screening systolic blood pressure < 110 mmHg Resting pulse oximetry < 92% (with or without supplemental oxygen) Neurological worsening (defined as NIHSS increase of 4 points compared to initial score) prior to screening.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 90 Day Modified Rankin Scale (mRS) score | Proportion of patients with a modified Rankin Scale score (min 0, max 5 with 0 being the best outcome) of 0-2 at 90 days | 90 days post bed rest | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pneumonia | Determine whether rates of pneumonia are at least similar in the two arms. Rates will be measured as percentages of the entire population at risk. | Duration of hospitalization stay, average 5 days | 
| Venous Thromboembolism | Determine whether rates of Venous Thromboembolism (VTE) are at least similar in the two arms. Rates will be measured as percentages of the entire population at risk. | Duration of hospitalization stay, average 5 days | 
| Neurological Worsening | Determine whether rates of neurological worsening are at least similar in the two arms. Rates will be measured as percentages of the entire population at risk. | Duration of hospitalization stay, average 5 days | 
| Readmission | Determine whether rates of readmission are at least similar in the two arms. | 90 days post bed rest | 
| Length of Stay | Determine whether length of hospital stay are at least similar in the two arms. This will be measured in days. | Duration of hospitalization stay, average 5 days |
