Non-progressive , CNS-based disorder of strength, muscle control, posture, or movement
due to brain injury acquired early in brain growth Implies absence of ongoing disease May be accompanied by perceptual problems, language deficits, and intellectual involvement
Etiology Of CP
76% are due to:Teratogens/toxins Genetic syndromes Brain malfomations Intrauterine infection Preeclampsia Complications of labor and delivery Sepsis/CNS infection Asphyxia *Prematurity Meningitis Traumatic brain injury
Etiology Of CP (Contd.)
24% cause is not obvious
Pathophysiology Of CP
*Anoxia plays the most significant role, which is frequently secondary to other causative factors:Hypoxia Ischemia Trauma Hemorrhage Congenital malformation Asphyxia
Pathophysiology Of CP (Contd.)
CNS relies on uninterrupted supply of blood, O2, and glucose O2 is essential to convert glucose to energy; if this action fails, acidosis results With prolonged hypoxia/acidosis:Infarction of white matter IVH Necrosis of cerebral cortex Subarachnoid or subdural hemorrhage
Clinical Manifestations Of CP
Five clinical classifications:Spastic CP Dyskinetic CP Ataxic CP Rigid/tremor/atonic CP (rare) Mixed CP
Spastic CP
Most common type Impairment of fine & gross motor skills Affected area of brain is motor cortex May involve one or both sides Characterized by:Deep tendon reflexes Hypertonia Sometimes contractures
Spastic CP: Classified
According
To Pattern Of Limb Involvement
Spastic quadriplegia:Spastic hemiplegia:All 4 extremities with complete loss of power and function Flexion contractures are common Associated defects
Leg and arm on one side are affected Obvious atrophy on affected side SZ disorders and mental retardation
Spastic CP: Classified According To Pattern Of Limb Involvement (Contd.)
Spastic diplegia:Monoplegia: rare occurrences Triplegia: rare occurrences Paraplegia: rare occurrencesLike parts on both sides of body affected Mental retardation is unusual Speech develops normally
Dyskinetic CP
Refers to injury in the basal ganglia Abnormal involuntary movements and posturesChorea is rapid, forceful movements of head and limbs Athetosis is slow, twisting, writhing of hands and feet; wormlike
Dyskinetic CP (Contd.)
Usually severe, but can be mild and confined to tongue, facial muscles or single limbCauses drooling and imperfect speech articulation
Ataxic CP
Affected area of brain is cerebellum Impaired balance and gait Intention tremor is a prominent sign Overall appearance of child is clumsy
Rigid/Tremor/Atonic CP
Rare Characterized by prolonged increase of muscle tone and disturbed posture Tremors at rest and on movement Speech impairment is usually severe Poor prognosis
Mixed CP
Combination of spasticity and athetosis
Associated Disabilities Of CP
Disturbed mental development Seizure activity Growth retardation Vision impairment Hearing impairment
Associated Disabilities Of CP (Contd.)
Drooling Dental problems Speech impairment Constipation Gait disturbances
Diagnosis Of Cerebral Palsy
Based on history and neuro exam Laboratory tests:Diagnostic tests:Electrolyte imbalances Metabolic defects Infectious disease Neoplastic disease
EEG CT scan
Medical Interventions
Mobilizing devices Orthopaedic surgery Medication Technical aids Involvement of specialists
Mobilizing Devices
Used to prevent or reduce deformityAnkle-foot orthoses (AFOs) Wheeled scooter boards/go-carts Customized strollers
Orthopaedic Surgery
To correct deformities To provide stability for an uncontrollable joint To provide balanced muscle power Surgery:Selective Dorsal Rhizotomy
Medication
Drugs to decrease spasticity have little usefulness in improving function in CP Antianxiety agents Skeletal muscle relaxants Diazepam (Valium) Local nerve blocks Antiepileptic medications Dextroamphetamines Botulinum toxin
Technical Aids
Electromechanical toys Appropriately designed toys and games Microcomputers/computers Electronic devices
Involvement Of Specialists
Visual and auditory deficits Dental care Physical therapy* Family, PT, OT, ST, health team Education Recreation
Nursing Care Of The Child With CP
Collaborate with family and supportive services to identify how to fulfill special needs and treatments during hospitalization
