Earlier Mobilization Post Acute Thrombectomy (EMPATHY-II)

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: 12-Hour Bed Rest; Subjects will be mobilized 12 hours after undergoing thrombectomy per usual care	Behavioral: Mobilization; Any movement out of bed
Active Comparator: 24-Hour Bed Rest; Subjects will be mobilized 24 hours after undergoing thrombectomy per usual care	Behavioral: Mobilization; Any movement out of bed

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
