• 1 other identifier: H00018239
• Study Type: interventional
• Target: N/A
• Locations: 0 countries
• Sites: N/A

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.

Conditions

Stroke; Stroke, Acute; Stroke, Ischemic

Keywords

Mobilization; Thrombectomy; Ischemia; Cerebrovascular Disorders; Brain Diseases; Recovery

Outcome Measures

Primary Outcomes (1)

• 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 Outcomes (5)

• Pneumonia

  Duration of hospitalization stay, average 5 days

• Venous Thromboembolism

  Duration of hospitalization stay, average 5 days

• Neurological Worsening

  Duration of hospitalization stay, average 5 days

• Readmission

  90 days post bed rest

• Length of Stay

  Duration of hospitalization stay, average 5 days

Study Arms (2)

Behavioral: Mobilization

24-Hour Bed Rest

ACTIVE COMPARATOR
