Acute Stroke Rehabilitation: Early Mobilization and Medical Management

Physiatric Role in Acute Stroke Care

Early Rehabilitation Consultation

PM&R consultation should be initiated within 24-48 hours of stroke admission. Physiatrist serves as the coordinator of the rehabilitation team in the acute setting. Key responsibilities: functional assessment, therapy prescription, medical complication prevention, disposition planning. Early involvement reduces length of stay and improves functional outcomes at discharge. Assess rehabilitation potential and appropriate level of post-acute care (IRF, SNF, home with services).

The Acute Stroke Team

Neurology/stroke service (acute medical management, thrombolysis, thrombectomy). PM&R (rehabilitation coordination, complication prevention, disposition). Physical therapy (mobility assessment, early mobilization). Occupational therapy (ADL assessment, upper extremity function).

Speech-language pathology (dysphagia screening, communication assessment). Nursing (positioning, skin care, bowel/bladder management). Social work/case management (discharge planning, caregiver support).

Early Mobilization

Evidence Base

The AVERT trial (2015) demonstrated that very early, high-dose mobilization within 24 hours of stroke onset was associated with reduced odds of favorable outcome at 3 months. Current consensus: early mobilization is beneficial, but "very early" aggressive mobilization may be harmful. AHA/ASA guidelines recommend mobilization within 24-48 hours for most patients. Low-dose, frequent mobilization appears safer than high-dose early activity.

Mobilization Protocol

Day 0-1: head of bed elevation, in-bed exercises, sitting on the edge of the bed (if medically stable). Day 1-2: standing with assistance, transfer training. Day 2+: progressive ambulation as tolerated. Contraindications to early mobilization: hemodynamic instability, active hemorrhage, unstable fracture, acute DVT/PE, severe medical illness.

Medical Stability Criteria

Systolic BP <220 mmHg (or <180 after thrombolysis). Heart rate 40-120 bpm. Oxygen saturation >92% on supplemental O2. Temperature <38.5 degrees Celsius. No acute cardiac event or arrhythmia. No deteriorating neurological status.

Medical Complications Prevention

Dysphagia and Aspiration

Dysphagia occurs in 37-78% of acute stroke patients. All patients should have a bedside swallowing screen BEFORE oral intake (NPO until screened). Validated screening tools: Gugging Swallowing Screen (GUSS), Toronto Bedside Swallowing Screening Test (TOR-BSST). Failed screen triggers formal SLP evaluation and instrumental assessment (VFSS or FEES).

Aspiration pneumonia is the leading cause of death in the first month after stroke. Diet texture modification based on swallowing assessment. Oral hygiene is critical for reducing aspiration pneumonia risk.

DVT Prophylaxis

Stroke patients have a high risk of VTE (incidence 20-50% without prophylaxis). Pharmacologic prophylaxis: LMWH (enoxaparin 40 mg daily) or UFH (5000 units BID-TID). Begin 24-48 hours after ischemic stroke (earlier if no hemorrhagic transformation). Delay in hemorrhagic stroke until bleeding is stable (timing controversial, typically 48-72 hours).

Intermittent pneumatic compression devices for all immobilized patients. Graduated compression stockings alone are NOT recommended (CLOTS trials).

Blood Pressure Management

Acute ischemic stroke (no thrombolysis): permissive hypertension; treat only if >220/120 mmHg. Post-thrombolysis (tPA): maintain BP <180/105 mmHg for 24 hours. Post-thrombectomy: individualized targets, often <160/90. Hemorrhagic stroke: target SBP <140 mmHg (INTERACT2, ATACH-2 trials).

Avoid aggressive BP lowering that may compromise penumbral perfusion. Gradual transition to outpatient antihypertensive regimen during rehabilitation.

Temperature Management

Fever (>38 degrees Celsius) in acute stroke is associated with worse outcomes. Aggressive fever management with acetaminophen and cooling measures. Search for infection source (pneumonia, UTI, line infection). Hypothermia protocols remain investigational.

Glycemic Control

Hyperglycemia (>180 mg/dL) in acute stroke worsens outcomes. Target glucose 140-180 mg/dL. Avoid hypoglycemia (<70 mg/dL), which is equally harmful. Insulin infusion protocols in the acute setting; transition to subcutaneous regimen.

Bowel and Bladder Management

Urinary retention is common; avoid indwelling catheters when possible (UTI risk). Bladder scan protocol: intermittent catheterization if PVR >300 mL. Constipation prevention: bowel program with stool softeners and scheduled toileting. Fecal incontinence: scheduled toileting, dietary modification.

Neurological Assessment and Monitoring

NIHSS (National Institutes of Health Stroke Scale)

Standardized stroke severity assessment (0-42 points). Serial assessments to track improvement or deterioration. Score correlates with stroke severity, prognosis, and rehabilitation potential. Scores 1-4: minor stroke; 5-15: moderate; 16-20: moderate-severe; >20: severe.

Monitoring for Neurological Deterioration

Stroke progression (extending ischemia). Hemorrhagic transformation (2-7% after ischemic stroke; higher with thrombolysis). Malignant cerebral edema (large MCA strokes; peak 2-5 days). Seizures (5-10% in first 2 weeks). Recurrent stroke.

Rehabilitation Assessment

Functional Assessment

FIM or AM-PAC scoring at admission and discharge. Berg Balance Scale. Functional Ambulation Category (FAC). Modified Rankin Scale (mRS) for global disability. Assessment of ADL independence (Barthel Index).

Determining Rehabilitation Disposition

Inpatient Rehabilitation Facility (IRF): patients who can tolerate 3 hours of therapy/day, have medical stability, and rehabilitation goals; best outcomes for moderate-severe stroke. Skilled Nursing Facility (SNF): patients who cannot tolerate IRF-level intensity or have significant medical comorbidities. Home with outpatient therapy: mild deficits with adequate home support. Long-term acute care (LTAC): ongoing medical complexity requiring extended acute-level care.

Prognostic Indicators for Functional Recovery

Younger age. Lower initial NIHSS score. Early return of motor function (especially hand/finger movement). Absence of severe neglect or aphasia. Pre-stroke independence. Supportive social environment. Absence of significant comorbidities.

Secondary Prevention

Antithrombotic Therapy

Antiplatelet therapy for non-cardioembolic ischemic stroke (aspirin 81-325 mg; dual antiplatelet therapy with clopidogrel for 21-90 days in minor stroke/TIA). Anticoagulation for cardioembolic stroke (atrial fibrillation): warfarin or DOACs; timing of initiation based on stroke size and hemorrhagic risk. Antihypertensive therapy: target <130/80 for most patients after the acute phase. Statin therapy: high-intensity statin for all ischemic stroke patients (atorvastatin 80 mg).

Risk Factor Modification

Smoking cessation. Diabetes management (A1c <7%). Weight management and dietary counseling (Mediterranean or DASH diet). Exercise prescription after the acute phase. Obstructive sleep apnea screening and treatment.

Clinical Pearls

Dysphagia screening before any oral intake is the single most important acute intervention for preventing aspiration pneumonia. Early mobilization is beneficial, but the AVERT trial taught us that "more is not always better" in the first 24 hours. Indwelling urinary catheters should be removed as soon as possible; every day of catheterization increases UTI risk. The NIHSS is essential for serial monitoring and disposition planning; all physiatrists should be proficient in its administration.

Neglect and anosognosia are stronger predictors of poor rehabilitation outcome than motor deficits alone. DVT prophylaxis should not be delayed in ischemic stroke; the risk of PE exceeds the risk of hemorrhagic transformation in most cases. Shoulder positioning and sling use should begin in the acute phase to prevent hemiplegic shoulder pain. Depression screening should begin in the acute phase; early treatment improves rehabilitation engagement.
