Earlier Mobilization Post Acute Thrombectomy

Phase 3

Withdrawn

• Conditions: Stroke; Stroke, Acute; Stroke, Ischemic
• Interventions: Behavioral: Mobilization

• Registration Number: NCT04153955
• Lead Sponsor: Brian Silver

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.

Arm && Interventions

Group	Intervention	Description
24-Hour Bed Rest	Mobilization	Subjects will be mobilized 24 hours after undergoing thrombectomy per usual care
12-Hour Bed Rest	Mobilization	Subjects will be mobilized 12 hours after undergoing thrombectomy per usual care

Primary Outcome Measures

Name	Time	Method
90 Day Modified Rankin Scale (mRS) score	90 days post bed rest	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

Secondary Outcome Measures

Name	Time	Method
Venous Thromboembolism	Duration of hospitalization stay, average 5 days	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.
Pneumonia	Duration of hospitalization stay, average 5 days	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.
Readmission	90 days post bed rest	Determine whether rates of readmission are at least similar in the two arms.
Neurological Worsening	Duration of hospitalization stay, average 5 days	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.
Length of Stay	Duration of hospitalization stay, average 5 days	Determine whether length of hospital stay are at least similar in the two arms. This will be measured in days.
