The Effectiveness of Early Mobilization for Acute Ischemic Stroke Treated With Rt-PA or IA Thrombectomy

National Taiwan University Hospital122 enrolled

Overview

The purpose of the study will to test the hypothesis that combining early out-of-bed mobilization within 72 hours of stroke onset with treated by intravenous recombinant tissue-type plasminogen activator (IV-rtPA) or endovascular thrombectomy (ET) would result in a greater benefit than standard early rehabilitation within 72 hours of stroke onset with treated by IV-rtPA or ET.

The treatments for acute ischemic stroke have evolved rapidly in recent years including intravenous (IV) thrombolysis using recombinant tissue-type plasminogen activator (rtPA) and endovascular thrombectomy (ET). Those new interventions constitute a landmark change in stroke treatment. Since early mobilizing patients after stroke as early as possible might prevent immobility-related complications and promote brain recovery, previous studies supported that early mobilization should commence at some point within 72 hours of stroke. However, increased risk of symptomatic intracerebral hemorrhage or ischemia-reperfusion injury underlies concerns early mobilization of patients treated with rtPA or ET. Bedside, a limited amount of research has investigated what specific timing for starting early mobilization after intravenous IV rtPA or ET would optimize recovery potential during the acute period after cerebral infarction. Further research is needed to understand whether the outcomes resulting from starting mobilization within 72 hours of onset for a stroke treated with rtPA or ET is better than that of starting mobilization later. Therefore, the purpose of the study will to test the hypothesis that combining early out-of-bed mobilization within 72 hours of stroke onset with treated by IV rtPA or ET would result in a greater benefit than standard early rehabilitation within 72 hours of stroke onset with treated by IV rtPA or ET.

Interventions

standard early rehabilitationBEHAVIORAL

The standard early rehabilitation program is an intervention regularly utilized in the stroke center of National Taiwan University Hospital. Activities performed in the standard early rehabilitation program within 24-72 hours of onset include(1) bed exercises including the joint range of motion exercise, bridge exercise, the straight leg raising exercise, stretching exercises, and facilitation techniques, and (2) functional training in which the patients are instructed to engage in the repetitive and systematic practice of tasks, such as rolling or sitting supported on the bed.

adding early out-of-bed mobilizationBEHAVIORAL

Early mobilization treatment involving out-of-bed, task-specific activities including rolling and sitting up, sitting unsupported out of bed, and standing within 24-72 hours of onset and accounting for more than two thirds of the treatment time in early rehabilitation .

Outcomes

Primary Outcomes

The total score-change of the Functional Independence Measure (FIM) assessment for daily living function

The total FIM with total score ranges from 13 to 126, which was used to assess each patient's capacities in terms of activities of daily living, comprises 18 seven-level items and assesses dependence in self-care, sphincter management, transfer, locomotion, communication, social interaction, and cognition. The functional independence of patient's capacities in terms of activity of daily living. Higher values represent a better outcome and all subscales are summed as a total score.

Time frame: at baseline, at 2 weeks after stroke, at 4 weeks after stroke, and at follow-up 3 months after stroke

Secondary Outcomes

The total score-change of the Postural Assessment Scale for Stroke Patients (PASS) assessment for postural stability

The Postural Assessment Scale for Stroke Patients (PASS): The PASS contains 12 four-level items of varying difficulty for assessing a patient's ability to maintain or change a given lying, sitting, or standing posture. Its total score ranges from 0 to 36.Higher values represent a better outcome and all subscales are summed as a total score.

Time frame: at baseline, at 2 weeks after stroke, at 4 weeks after stroke, and at follow-up 3 months after stroke

Achievement of the walking motor milestones

the achievement of the three motor milestones (yes or no/ days)

Time frame: within 2 weeks after stroke
