Подробное описание
Background: The primary goal of most acute stroke interventions is to restore cerebral blood flow (CBF) in the affected region and prevent hypoperfusion during early clinical course. Diffuse optical technology offers a new opportunity for invasive, real time and bedside assessment of brain function biomarkers, including CBF.
However, whether CBF monitoring can identify patients who are most likely to benefit from therapies is unclear. The results of AVERT trial suggested that the benefit of early mobilization (EM) after stroke on functional outcome may be outweighed by a hypothetical deleterious effect on cerebral perfusion if cerebral autoregulation (CA) is impaired. EM could improve recovery outcomes after stroke in selected patients based on the status of CA function.
Objectives: 1) to investigate if EM leads to superior motor and functional outcome after stroke compared to standard care (SC) in selected patients based on optical biomarkers of CA. 2) To evaluate the feasibility of the clinical use of a novel transcranial optical monitoring system adapted to deliver biomarkers of CA at the bedside.
Methodology: A randomized controlled, open-labeled trial with blinded assessment of outcome end-points in a stroke unit of a tertiary stroke center. Patients with an ischemic or hemorrhagic stroke will be randomly assigned within 24 hours after symptoms onset to receive SC alone or EM in addition to SC. All patients will undergo optical monitoring of CA on admission to the Stroke Unit. Randomization will be stratified according to stroke severity measured with the National institute of Health Stroke Scale (NIHSS) and type of stroke (ischemic or hemorrhagic). Clinical outcome will be assessed with the Postural Assessment Scale for Stroke (PASS) and modified Rankin scale at 90 days. Safety outcome will be assessed by recording the incidence of neurological deterioration, recurrence and falls.
Expected results: to provide a new in vivo biomarker of cerebrovascular function for more accurate and earlier prediction of response to therapy, leading to improved clinical decisions and outcomes.

Группа участников / Армия |
Вмешательство/лечение |
|---|---|
|
Активный компаратор: Standard care group
Standard of care (SC) mobility protocol performed by the Stroke Unit nursing and physiotherapy staff.
The SC consists of one or two sessions per days of out-of-bed sitting and standing, adapted to patient´s tolerability, and one session of physiotherapy per day.
Mobilization will be schedule to start from 24 hours from symptoms onset according to the local Stroke Unit protocol.
|
Standard protocol of mobilization in acute stroke patients admitted to the Stroke Unit at the discretion of the nursing and physiotherapy staff
|
|
Экспериментальный: Intensive mobilization group
The Intensive mobilization intervention will include the standard care plus at least two additional sessions each day of at least 20 minutes each session focused on task specific sitting, standing and walking activities.
The intervention will be schedule to start at 24 hours from symptoms onset and will last 14 days or until the patient is discharged.
|
Additional 2 or more sessions of out-of-bed activity to the standard stroke care, focused in active sitting, standing and walking assisted by physiotherapists

Postural Assessment Scale for Stroke
Временное ограничение: 90 days
|
Balance and mobility assessed with the Postural Assessment Scale for Stroke patients (PASS), in its validated Spanish version.
The PASS contains 12 four-level items of varying difficulty for assessing ability to maintain or change a given lying, sitting, or standing posture.
Each item is scored from 0 to 3, with 0 being the lowest level of functionality and 3 the highest.
The total score ranges from 0 to 36 (highest score best).
