What the 2026 rehabilitation guideline adds
Rehabilitation starts during acute care and continues across settings. The August 2026 AHA/ASA guideline emphasizes coordinated therapy, reassessment as needs change, caregiver training, and repeated checks for depression and anxiety.6
Early assessment and individualized activity remain distinct from AVERT's intensive mobilization protocol in the first 24 hours. The appropriate dose changes with medical stability and recovery; the trial is not a reason to postpone rehabilitation.

The question families ask on day one is almost always the same: when does therapy start? The honest answer is that stroke medicine changed its mind about this, and the reason is a single large trial.
AVERT randomized 2104 patients at 56 stroke units across five countries to either usual stroke-unit care or usual care plus a protocol of frequent, higher-dose, out-of-bed mobilization begun within 24 hours of onset. The very early, higher-dose group did worse. Forty-six percent reached a favorable three-month outcome (modified Rankin 0–2) compared with 50% in usual care — an adjusted odds ratio of 0.73 (95% CI 0.59–0.90, p=0.004).3 Mortality was numerically higher but not statistically different (8% vs 7%), and there was no reduction in the immobility complications the protocol was designed to prevent.
AVERT is routinely summarized as "don't mobilize early." That is not what it showed. In the arm that did better, 59% of patients were still mobilized within 24 hours. Ninety-two percent of the intervention arm were. Both groups started early; one started harder. Because timing and dose differed, the trial cannot identify which component caused the outcome difference. Reading it as permission to leave a stroke patient in bed is a misreading with its own harms — deconditioning, pneumonia, pressure injury, and venous thromboembolism.
So what should happen in the first 24 hours?
Plenty — just not aggressive out-of-bed dosing. The first day is for assessment and prevention: a swallow screen before anything passes the lips, positioning, skin and pressure care, blood-pressure and glucose management, mood and communication assessment, and getting therapy services consulted so the plan is built while the medical picture is still being sorted out.
Nothing about AVERT argues for delaying a swallow screen. That screen is arguably the single most protective order on admission, and the consequences of skipping it are covered separately in our review of post-stroke dysphagia. Nor does AVERT argue against sitting a stable patient up, or against short, well-tolerated sessions. What it argues against is a protocolized push to get everyone out of bed early and often, regardless of how they are tolerating it.
For the wider picture of what else is being managed in that same window — imaging, blood pressure, antithrombotics, monitoring — see the first 24 hours after a stroke.
Early, but titrated to the patient
The practical translation is that timing is not a single switch. Guidelines from the AHA/ASA support organized, interdisciplinary rehabilitation for appropriate patients, and the VA/DoD guideline recommends task-specific practice to improve motor function, gait, posture, and activities of daily living.12 Neither says "more, sooner, for everyone."
The 2026 AHA/ASA rehabilitation guidance supports moderate to high-intensity exercise and task practice after the first 24 hours, as appropriate to the person and supervised plan. It does not mean every patient should begin the same activity at hour 25. Medical stability, deficits, tolerance and safety determine the plan; the team should explain which activities are safe today and when they will reassess.
AVERT DOSE was designed to study different early mobility regimens in mild and moderate ischemic stroke.5 The cited 2023 paper describes the design; it does not itself report outcomes. Follow the study team’s updates for subsequent reports. A trial regimen should not be turned into a home exercise prescription.
The decision that matters more than the first 24 hours
Where the first days genuinely determine the next six months is the discharge fork: inpatient rehabilitation facility, skilled nursing facility, or home with outpatient or home-based therapy.
That decision turns on how much therapy the patient can tolerate, the trajectory of the deficit, cognition and continence, caregiver availability, and insurance authorisation. It is worth starting the conversation days before discharge is imminent, because the paperwork and the bed availability are frequently the rate-limiting step, not the clinical judgement. The discharge checklist lays out what needs to be settled. Functional status at that moment is usually anchored on the modified Rankin Scale — the same 0–2 threshold AVERT used as its outcome.
A patient who leaves the hospital without a named next setting and a scheduled follow-up has lost something much more consequential than a few early sessions.
How recovery actually works: repetition, not intensity for its own sake
The mechanism behind rehabilitation is task-specific practice — repeating the actual movements and activities that matter, with attention and safe technique. The Cochrane review of repetitive task training pooled 33 trials and 1853 participants: low-quality evidence of improvement in arm and hand function, moderate-quality evidence for walking distance (mean difference roughly 35 metres) and functional ambulation, with benefits sustained to about six months.4
Two honest caveats belong alongside that. The effect sizes are modest, not transformative. And the review did not find that outcomes were modified by the dose of practice or by time since stroke — that older review cannot establish that intensity never matters or replace the 2026 recommendations.
What this means in practice: match the practice to the deficit. Aphasia needs a different plan from neglect, foot drop, shoulder subluxation, or severe fatigue. Recovery is also not linear, and the weeks-to-months arc — including plateaus and late gains — is mapped out in the stroke recovery timeline. Common complications that derail practice, particularly spasticity and post-stroke fatigue, deserve to be treated as rehabilitation problems rather than as patient motivation problems.
Rehabilitation activity should be guided by the medical and rehabilitation team. New weakness, new speech difficulty, severe headache, chest pain, shortness of breath, or a sudden decline is not a rehab problem — it is a reason to seek urgent medical care.
For caregivers
| Ask today | Write the agreed plan |
|---|---|
| What can we safely practice? | Task, assistance or equipment needed, and who demonstrated it. |
| How much and how often? | The therapist’s plan, including rest and when to stop. |
| What changes need help? | Warning symptoms and the appropriate contact. |
| When will this be reviewed? | Next assessment and plan after discharge. |
This original question sheet supports the treating team’s instructions; it does not prescribe exercises or a rehabilitation dose.
Caregivers are often the quiet engine of stroke recovery, and the most useful thing a family member can do early is get specific. Ask the therapists which two or three tasks should be practised between sessions, write down the safe technique, and keep the environment set up so practice is possible.
Avoid doing every task for the survivor if they can safely participate — and equally, do not turn practice into a test of willpower. Fatigue after stroke is physiological, not a failure of motivation. The goal is safe participation within the prescribed plan, with rest and adjustments when needed.
The takeaway
Early rehabilitation is standard of care. The nuance AVERT added is that early and aggressive are not synonyms, and that assuming more is better cost patients function in a well-run randomized trial. Start when the patient is stable, keep sessions tolerable, get the swallow screen and the discharge plan right, and let the therapy team titrate the dose to the person in front of them.
Frequently asked questions.
When should physical therapy start after a stroke?
After medical stability. Bedside PT, OT, and speech-language pathology on the stroke unit is usual care, and assessment typically begins on the first day. High-dose out-of-bed activity within the first 24 hours is the specific AVERT caution — it is not a reason to delay a swallow screen, a positioning plan, or a therapy consult.
Is it dangerous to get out of bed too soon after a stroke?
In the AVERT trial, frequent, higher-dose, very early mobilization was associated with worse function at three months than usual stroke-unit care. Importantly, most patients in the better-performing usual-care arm were still mobilized within 24 hours. The trial does not isolate timing from dose and frequency. The pace should be set by the treating team based on how the patient tolerates activity.
Inpatient rehab vs skilled nursing vs home — who decides?
The treating team decides with the patient and family, based on how much daily therapy the patient can tolerate, the deficits being treated, cognition and continence, caregiver support at home, and insurance authorisation. Start the conversation early, because bed availability and authorisation are often slower than the clinical decision. See the discharge checklist for what needs to be settled before discharge.
How is this different from the stroke recovery timeline?
This page covers the first days — when to start, how hard, and where the patient goes at discharge. The stroke recovery timeline covers the weeks-to-months arc: what typically returns when, where plateaus occur, and what late recovery looks like.
What should stroke survivors practice at home?
The activities recommended by the rehabilitation team. Common examples include safe transfers, walking drills, hand use, speech exercises, swallowing strategies, and daily tasks such as dressing or grooming. The specific plan depends on the deficits and the safety risks, which is why it should come from the therapists who assessed the patient.
Why is repetition important after stroke?
Task-specific repetition is the mechanism behind motor recovery. A Cochrane review of 33 trials found improvements in arm function, hand function, walking distance, and functional ambulation, sustained to about six months. The effects are real but modest, and the review did not find that outcomes improved with higher doses of practice.
How can caregivers help stroke recovery?
Learn the therapy plan, ask which specific tasks to practise between sessions, keep the home environment safe, watch for new symptoms, support mood and sleep, and celebrate small gains without taking over tasks the survivor can safely attempt.
