Post-Stroke Rehabilitation in Kathmandu — Recovery & Secondary Prevention

Why post-stroke rehabilitation matters

Stroke causes sudden brain damage, leading to varied deficits depending on location and extent: weakness, sensory loss, language difficulties, cognitive impairment, vision problems, swallowing difficulty. The brain has remarkable capacity for recovery through neuroplasticity — reorganization and formation of new neural connections. Rehabilitation harnesses neuroplasticity through intensive, repetitive, task-specific training.

Goals: Regain maximum function and independence, prevent complications (contractures, falls, pneumonia, depression), reduce disability, improve quality of life, prevent recurrent stroke.

Timing: Early intensive rehabilitation (starting within 24-48 hours) improves outcomes. Most recovery occurs in first 3-6 months, but continued gains are possible for 1-2 years with ongoing therapy.

Components of post-stroke rehabilitation

1. Physical Therapy (PT):

• Mobility training: Sitting balance, standing, gait training, stair climbing
• Strength exercises: Affected limb strengthening, core stability
• Balance and coordination: Reducing fall risk
• Constraint-induced movement therapy (CIMT): Restricting unaffected limb to force use of affected limb — improves motor recovery when used intensively
• Range-of-motion exercises: Preventing contractures

2. Occupational Therapy (OT):

• Activities of daily living (ADL) retraining: Dressing, bathing, grooming, eating, toileting
• Fine motor skills: Hand and finger exercises for writing, buttoning, using utensils
• Adaptive equipment: Grab bars, shower chairs, dressing aids, button hooks, modified utensils
• Home safety assessment: Fall prevention, bathroom modifications, kitchen adaptations
• Cognitive strategies: Compensatory techniques for memory, attention deficits

3. Speech and Language Therapy:

• Aphasia therapy: Language comprehension and expression retraining. Broca aphasia (non-fluent, difficulty speaking), Wernicke aphasia (fluent but nonsensical), global aphasia (severe impairment)
• Dysarthria treatment: Articulation exercises for slurred speech
• Swallowing therapy (dysphagia): Evaluation (videofluoroscopy/FEES if available), texture modifications (thickened liquids, soft diet), compensatory techniques (chin tuck, head turn), strengthening exercises. Dysphagia increases aspiration pneumonia risk — critical to address
• Communication aids: Picture boards, writing, speech-generating devices

4. Cognitive Rehabilitation:

• Memory strategies: External aids (calendars, notebooks), mnemonic techniques
• Attention training: Sustained and selective attention exercises
• Executive function: Problem-solving, planning, organization skills
• Neglect treatment: Visual scanning training for hemispatial neglect (ignoring left side common after right hemisphere stroke)

5. Psychological Support:

• Post-stroke depression: Affects 30-50% of survivors. Symptoms: sadness, anhedonia (loss of pleasure), sleep/appetite changes, fatigue, hopelessness. Treatment: SSRIs (sertraline, escitalopram), cognitive-behavioral therapy (CBT), caregiver support. Depression impairs rehabilitation participation — screening and treatment are essential.
• Anxiety: Fear of recurrent stroke, falls, loss of independence. Treat with counseling, relaxation techniques, medications if severe.
• Emotional lability (pseudobulbar affect): Uncontrolled crying/laughing after stroke. Can be treated with SSRIs or dextromethorphan/quinidine (limited availability).

Spasticity management after stroke

Spasticity (involuntary muscle tightness) develops in 20-40% of stroke survivors, typically weeks to months after stroke. Common patterns: flexed elbow and wrist with clenched fist (upper limb), extended knee with pointed foot/inverted ankle (lower limb — equinovarus deformity).

Problems caused by spasticity: Pain, difficulty with ADLs (dressing, hygiene, positioning), impaired gait, skin breakdown (clenched fist → palm maceration), contractures (permanent joint stiffness if untreated).

Treatments:

• Physical therapy: Stretching, passive range-of-motion, splinting (maintain joint position), positioning, heat/ice.
• Oral medications: Baclofen (5-80 mg/day divided TID-QID), tizanidine (2-36 mg/day divided TID). Efficacy is modest; side effects (sedation, weakness, hypotension) limit dosing.
• Botulinum toxin injections: Highly effective for focal spasticity. Injected into specific tight muscles → temporary muscle relaxation (3-4 months). Allows improved function, easier care, pain reduction. Repeat injections as needed. Available in Kathmandu (Dr. Jitendra provides botulinum toxin injections for post-stroke spasticity).
• Intrathecal baclofen pump: For severe generalized spasticity. Surgically implanted pump delivers baclofen directly into spinal fluid. Limited availability in Nepal.

Secondary stroke prevention — preventing recurrence

Recurrent stroke risk: 5% in first year, 25-40% over 5 years without prevention. Secondary prevention reduces recurrence by 60-80%.

Medications:

• Antiplatelet therapy: Aspirin 75-325 mg daily, clopidogrel 75 mg daily (more effective than aspirin alone), or aspirin + clopidogrel for 21-90 days post-high-risk stroke (then monotherapy).
• Anticoagulation: For cardioembolic stroke (atrial fibrillation) — warfarin (INR 2-3) or DOAC (apixaban, rivaroxaban, dabigatran). DOACs preferred (no monitoring needed, fewer bleeds) but cost and availability in Nepal vary.
• Statin: Atorvastatin 40-80 mg or rosuvastatin 20-40 mg — lowers LDL, stabilizes plaque, reduces recurrent stroke regardless of baseline cholesterol.
• Blood pressure control: Target <140/90 mmHg (some guidelines <130/80). ACE inhibitors or ARBs preferred. Do NOT lower BP acutely in first days after ischemic stroke (may worsen penumbra perfusion).
• Diabetes control: HbA1c <7%. Metformin, SGLT2 inhibitors (empagliflozin — cardiovascular benefit), GLP-1 agonists (semaglutide — stroke reduction). Intensive glycemic control during acute stroke avoided (risk of hypoglycemia worsens outcome).

Lifestyle modifications:

• Smoking cessation: Reduces stroke risk by 50% within 2 years. Refer to cessation programs, nicotine replacement therapy.
• Diet: Mediterranean diet (vegetables, fruits, whole grains, fish, olive oil, nuts), low salt (<5g/day), limit red meat and processed foods.
• Exercise: 150 minutes/week moderate aerobic activity (brisk walking, cycling) + strength training 2 days/week. Start gradually post-stroke, coordinate with PT.
• Weight loss: If overweight/obese — target BMI 18.5-24.9.
• Alcohol: Limit to ≤2 drinks/day men, ≤1 drink/day women. Heavy drinking increases stroke risk.

Carotid revascularization:

For severe carotid stenosis (>70% symptomatic, >80% asymptomatic): carotid endarterectomy (surgical plaque removal) or carotid artery stenting. Reduces ipsilateral stroke risk. Available at major hospitals in Kathmandu (vascular surgery, interventional radiology).

Rehabilitation resources in Kathmandu

Physiotherapy centers:

• National Trauma Center (NAMS) Physical Medicine and Rehabilitation Department
• TUTH (Tribhuvan University Teaching Hospital) Rehab Department
• Private rehabilitation hospitals and outpatient PT clinics

Speech therapy: Limited availability — some private hospitals and specialized clinics offer speech/language pathology services.

Occupational therapy: Growing availability in Kathmandu — inquire at rehab hospitals.

Dr. Jitendra coordinates referrals to appropriate rehabilitation facilities based on patient needs, severity, and insurance/financial considerations.

Long-term outlook and recovery expectations

Recovery timeline: Fastest improvement in first 3 months (acute recovery phase), continued gains 3-12 months (subacute phase), plateau after 1-2 years (chronic phase). Late gains still possible with continued therapy.

Functional outcomes: Vary widely by stroke severity. Mild strokes: near-complete recovery common. Moderate strokes: most regain walking, many return to work with accommodations. Severe strokes: significant disability common, but meaningful gains still achievable with intensive rehabilitation.

Predictors of good recovery: Younger age, smaller stroke size, less severe initial deficits, absence of cognitive impairment or aphasia, early intensive rehabilitation, good social support, absence of medical complications (recurrent stroke, infections, falls).

Caregiver support: Family caregivers play critical role in recovery — education on safe transfers, exercises, medication management, recognizing complications. Caregiver burnout is common — respite care, support groups, counseling help.

When to seek follow-up

Regular neurology follow-up: 1 month post-stroke, then every 3-6 months first year, then annually if stable. Follow-up includes: neurological exam, medication review and optimization, screening for depression, recurrent stroke risk assessment, rehabilitation progress review, caregiver support.

Seek urgent evaluation for: sudden new weakness, speech change, vision loss, severe headache (may indicate recurrent stroke or hemorrhagic transformation), new seizures, falls with injury, worsening swallowing difficulty, signs of depression.
