Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older hospitalized with acute ischemic stroke who can undergo carotid and transcranial Doppler and be mobilized within 48 hours are ideal candidates.
✕Probably not a fit
Patients with pre-existing severe disability (mRS ≥ 4), severe hemodynamic instability, recent neurosurgery, or inability to undergo Doppler assessment are unlikely to benefit from this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a multicenter, pragmatic, randomized controlled trial with a PROBE design that assigns adults with acute ischemic stroke to Doppler-guided early mobilization within 48 hours versus standard care. Clinicians use carotid and transcranial Doppler ultrasound to evaluate hemodynamic stability and determine timing and intensity of initial mobilization. Blinded outcome assessors measure three-month outcomes including the modified Rankin Scale, cognitive function, quality of life, patient-reported outcomes, length of stay, blood pressure evolution, and adverse events. The trial is conducted at neurology departments in Coimbra, Lisbon, and Porto to provide practical evidence for tailoring early mobilization after stroke.
Why it matters
Potential benefit: If successful, this approach could reduce complications, shorten hospital stays, and improve functional and cognitive recovery by tailoring mobilization to each patient's hemodynamic status.
How similar studies have gone: Previous early-mobilization studies have shown mixed benefits and generally did not use systematic Doppler-guided hemodynamic assessment, making this approach partially novel and not yet proven.
