Stroke, Acute Ischemic
Conditions
Brief summary
The effect of head position as a nonpharmacological therapy on acute ischemic stroke (AIS) remains inconclusive. Recent HOPES2 (Head dOwn-Position for acutE moderate ischemic Stroke with large artery atherosclerosis) suggest the safety, feasibility, and potential benefit of the head-down position (HDP) in acute ischemic stroke. The current study aims to investigate the efficacy and safety of HDP in acute moderate ischemic stroke patients with large artery atherosclerosis.

Inclusion criteria
* Age ≥ 18 years old * Acute ischemic stroke confirmed by NCCT or MRI; * Moderate neurologic deficit (6≤ NIHSS ≤ 16) within 24 hours of onset, or progressing from mild (NIHSS ≤ 5) to moderate neurologic deficit (6≤ NIHSS ≤ 16) within 24 hours, requiring ≥ 4 point increase in NIHSS score although the onset time is beyond 24 hours; * Probable large artery atherosclerosis etiology based on the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria (responsible artery stenosis ≥ 50% or occlusion); * Anterior circulation stroke (internal carotid artery, M1 or M2 of middle cerebral artery); * First stroke onset or past stroke without obvious neurological deficit (mRS≤2); * Signed informed consent.
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| proportion of favorable functional outcome | 90±7 days | favorable functional outcome defined as modified Rankin Score (mRS) 0-2. The minimum and maximum values of mRS are 0 and 6, respectively; higher score mean a worse outcome |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| proportion of excellent functional outcome | 90±7 days | excellent functional outcome is defined as modified Rankin Score (mRS) 0-1. The minimum and maximum values of mRS are 0 and 6, respectively; higher score mean a worse outcome |
| ordinal distribution of modified Rankin Score (mRS) | 90±7 days | The minimum and maximum values of mRS are 0 and 6, respectively; higher score mean a worse outcome |
| early neurological deterioration (END) | 48±12 hours | END is defined as more than 4-point increase in NIHSS within 48±12 hours, but was not a result of intracerebral hemorrhage |
| early neurological improvement (ENI) | 48±12 hours | ENI is defined as more than 4-point decrease in NIHSS within 48±12 hours |
| Changes in National Institute of Health stroke scale (NIHSS) | 48±12 hours | the minimum and maximum values of NIHSS are 0 and 42, respectively; higher NIHSS mean a worse outcome. |
| changes in infarct volume | 48±12 hours | — |
| new stroke or other vascular event(s) | 90±7 days | — |
