Brief summary
Early mobilization was thought to be effective in patients with acute ischemic stroke. As the essential component of stroke unit care, early mobilization has already been part of routine clinical practice. However, it is uncertain that which and when medical service focusing on functional recovery should be delivered after the emergency interventions for stroke. Besides, the optimal time window, for delivering early mobilization after acute ischemic stroke, has not been verified with strong evidence.
Detailed description
The TIME Trial is a pragmatic, investigator-initiated, multi-center, randomized, 3-arm parallel group, clinical trial. This trial will be conducted in 57 general hospitals in mainland China affiliated with the China Stroke Databank Center and will enroll 6033 eligible patients with acute ischemic stroke. Participants will be randomly allocated to either (1) the very early mobilization group in whichmobilization is initiated within 24 hours from stroke onset, (2) the early mobilization group in which mobilization begins between 24 and 72 hours poststroke, or (3) the late mobilization group in which mobilization is started after 72 hours poststroke. The mobilization protocol is otherwise standardized and identical for each comparison group. Mobilization is titrated by baseline mobility level and progress of patients throughout the intervention period. The primary outcome is death or disability assessed with the modified Rankin scale at 3 months poststroke. Secondary outcomes include impairment score of the National Institutes of Health Stroke Scale, dependence in activities of daily living as measured using the modified Barthel Index, cognitive ability assessed with the Mini-Mental State Examination, incidence of adverse events, hospital length of stay, and total medical costs. Study design: an Investigator-Initiated Prospective Multicenter Randomized 3-Arm Clinical Trial Sample size: 1500 cases
Interventions
The three study groups share a same intervention protocol in addition to the initiation timing of intervention from the stroke onset. The frequency and intensity of the intervention is titrated according to functional activity baseline and monitored daily and adjusted with recovery. Encourage patients to move out of bed as soon as possible. Definition of bed movement: Encourage and help patients to perform functional actions, focusing on activities such as sitting, standing, walking out of the bed.

Masking description
Pre-admission trial assistants and medical staff aware of group allocation will not have contact with the patients. At each study site, a group of physiotherapists will be responsible for the interventions for all three study groups. Multi-disciplinary physicians, assessors, data analysts, and statisticians will be blinded to the group allocation.
Intervention model description
Patients with acute ischemic stroke fulfilling the inclusion and exclusion criteria will be randomly allocated to either either (1) the very early mobilization group in whichmobilization is initiated within 24 hours from stroke onset, (2) the early mobilization group in which mobilization begins between 24 and 72 hours poststroke, or (3) the late mobilization group in which mobilization is started after 72 hours poststroke.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| modified Rankin Scale | 3 months after the cerebrovascular accident/or the last time appeared normally | modified Rankin Scale, to evaluate a subject's disability status. It's a rating data. The degrees range from 0 to 6, higher values represent a worse outcome and severe disability. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| modified Rankin Scale | the total score of mRS will be recorded 15days、1month、6months after the cerebrovascular accident/or the last time appeared normally | modified Rankin Scale, to evaluate a subject's disability status. It's a rating data. The degrees range from 0 to 6, higher values represent a worse outcome and severe disability. |
| MMSE | the total score of MMSE will be recorded 15days、1month、3 months、6months after the cerebrovascular accident/or the last time appeared normally | Mini-mental State Examination. To evaluate a subject's mental state.The total score range from 0 to 30, higher values represent a better outcome. |
| NIHSS scores | the total score of NIHSS will be recorded15days、1month、6months after the cerebrovascular accident/or the last time appeared normally | National Institute of Health stroke scale,total scores range from 0 to 42, higher values represent a better outcome. |
| Incidence of important medical events | The incidence of important medical events will be recorded 15days、1month、3 months after the cerebrovascular accident/or the last time appeared normally | falls, trauma, fracture, syncope, epilepsy, pneumonia, atelectasis, venous thrombosis, pulmonary embolism, pressure sores, death, etc. |
| Hospital LOS | Hospital LOS will be recorded 3 months after the cerebrovascular accident/or the last time appeared normally | length of stay in the acute hospital and in the rehabilitation hospital, and total hospital length of stay |
| Total medical cost | medical cost will be recorded 3 months after the cerebrovascular accident/or the last time appeared normally | addition of the cost of each admission of the acute hospital and the rehabilitation hospital |
| Barthel Index | the total score of Barthel Index will be recorded 15days、1month、3 months、6months after the cerebrovascular accident/or the last time appeared normally | ability of daily living, total scores range from 0 to 100, higher values represent a better outcome and independent living ability. |
