What Is Cerebral Palsy?
Cerebral palsy (CP) is a group of conditions that affect movement, muscle tone, and posture. It is caused by damage to — or abnormal development of — the brain that occurs before, during, or shortly after birth. "Cerebral" refers to the brain; "palsy" refers to the movement and muscle difficulties.
CP is the most common physical disability in childhood. In India, approximately 2–3 per 1,000 live births are affected. That means roughly 25,000–35,000 new cases every year in India alone.
CP is not a disease in the progressive sense — the brain injury itself does not worsen over time. However, the effects on movement and function change as the child develops. With appropriate therapy and support, most children with CP make substantial developmental progress.
Types of Cerebral Palsy
CP is classified by the type of movement disorder and the parts of the body affected:
By movement type:
- Spastic CP (75–88% of cases): Increased muscle tone causing stiffness and difficulty with movement. The most common type.
- Dyskinetic/Athetoid CP: Involuntary, uncontrolled movements — writhing (athetosis) or more sudden, jerky movements (chorea). Affects the whole body.
- Ataxic CP: Affects balance and coordination. Children appear unsteady and may have tremor.
- Mixed: Many children have features of more than one type.
By body parts affected:
- Hemiplegia: One side of the body (arm and leg on the same side)
- Diplegia: Both legs primarily (arms affected less)
- Quadriplegia/Tetraplegia: All four limbs, trunk, and usually face
Common Causes in the Indian Context
Premature birth: Prematurity is a significant risk factor. The immature brain is vulnerable to hemorrhage (bleeding) and periventricular leukomalacia (PVL — damage to white matter near the ventricles). India's rates of premature birth are high, and NICU survival has improved — meaning more premature babies survive who would not have previously, some of whom have CP.
Birth asphyxia: Oxygen deprivation during labor and delivery. Hypoxic-ischemic encephalopathy (HIE) causes significant CP in India due to challenges in intrapartum monitoring in some settings.
Infections during pregnancy: Meningitis, encephalitis, and TORCH infections (toxoplasmosis, rubella, cytomegalovirus, herpes).
Jaundice (kernicterus): Severe neonatal jaundice left untreated causes brain damage. This remains a cause in India in settings without adequate neonatal care.
Multiple pregnancy: Twins and triplets have higher risk.
Associated Conditions
CP affects movement, but the same brain injury or development difference that causes movement difficulty can also affect other brain functions. Many children with CP have one or more of:
- Intellectual disability (in about 50% of cases — though range varies widely)
- Epilepsy (25–35%)
- Speech and communication difficulties (oromotor involvement, dysarthria, AAC needs)
- Visual impairment (including cortical visual impairment — CVI)
- Hearing impairment
- Feeding difficulties (swallowing problems, especially in children with more severe involvement)
- Pain (muscle spasm, hip problems, dental issues)
- ADHD and learning differences
Assessment should address all these domains — not just motor function.
Therapy: What Makes a Difference
CP cannot be cured, but function, independence, and quality of life can be substantially improved with appropriate therapy. Early intervention is critical.
Physiotherapy (PT)
The core of CP management. PT addresses:
- Muscle tone management (techniques to reduce spasticity, improve range of motion)
- Strength and muscle activation
- Gross motor skills (rolling, sitting, crawling, standing, walking)
- Prevention of contractures (permanent shortening of muscles and tendons)
- Gait training
Frequency: At least 3–5 times weekly for children with significant motor involvement; intensive blocks followed by home programs.
Occupational Therapy (OT)
Fine motor skills, daily living activities (dressing, eating, writing), adaptive equipment, seating and positioning, and sensory processing.
Speech and Language Therapy
Communication (AAC for children with severe dysarthria), feeding and swallowing, and when relevant, language development.
Medical Management of Spasticity
- Oral medications: Baclofen, tizanidine — reduce spasticity but cause drowsiness
- Botulinum toxin (Botox) injections: Targeted injection into specific spastic muscles; reduces tone for 3–6 months, allowing more effective physiotherapy window. Available at major government hospitals and private centers.
- Intrathecal baclofen pump: For severe spasticity; a pump delivers baclofen directly to the spinal fluid. Available at specialized centers.
- Selective Dorsal Rhizotomy (SDR): Surgical procedure for spastic diplegia; can permanently reduce spasticity. Centers in India include CMC Vellore, AIIMS.
Orthoses (Splints/Braces) and Equipment
AFOs (ankle-foot orthoses), hand splints, standing frames, specialized seating, wheelchairs, and walkers are essential equipment for many children with CP. Fitting and adjusting these is a specialized skill — an OT or orthotist must be involved, not just prescription from a doctor.
Government Support in India
UDID (Unique Disability Identity Document): Apply at swavlambancard.gov.in. Required to access most government schemes.
Niramaya Health Insurance: Free health insurance scheme under NPPCD for persons with autism, CP, intellectual disability, and multiple disabilities. Covers hospitalization, surgery, OPD treatments up to ₹1 lakh/year. Apply at state welfare department.
Assistance for purchase of aids and appliances (ADIP Scheme): Government assistance to purchase orthotic devices, wheelchairs, AFOs, and other equipment. Apply at district Social Welfare office.
Disability pension: ₹200–2,000/month depending on state, for persons with 40%+ disability.
Transport concession: 75% concession on Indian Railways for person with disability + escort.
Income tax benefit: 80DD deduction for expenses on treatment/rehabilitation of dependent with disability.
RBSK (Rashtriya Bal Swasthya Karyakram): Free screening and management of children 0–18 for 32 conditions including CP, through government health system.
Where to Find Help in India
Government:
- NIMHANS (Bangalore): Neurology, developmental pediatrics, rehabilitation
- AIIMS Delhi: Pediatric neurology, rehabilitation
- CMC Vellore: Excellent pediatric neurology and rehabilitation
- Institute for Child Health (Kolkata): Developmental pediatrics
- KGMU Lucknow: Pediatric neurology
- District Early Intervention Centres (DEIC): First contact in every district
NGOs providing therapy:
- Spastics Society of India (Mumbai) — landmark institution
- ADAPT (Mumbai)
- TAMANA (Delhi)
- Vidyasagar (Chennai)
- Action for Autism (Delhi) — also serves CP
Equipment:
- Assistive Technology Society of India (ATSI)
- ALIMCO (Artificial Limbs Manufacturing Corporation of India) — government, subsidized orthotic devices
CP is not a life sentence of limitation. With the right support, children with CP learn, grow, develop relationships, and contribute to their communities. The trajectory depends substantially on what support is available — which is why knowing where to access it matters so much.
