E N D
Most common causes of motor delay: • Cerebral palsy2/1000 • Muscular dystrophy 1/3000 • Spina bifida <1/1000
ETIOLOGY Prenatal factors – infection, metabolic, anoxia, genetic, infarction Perinatal – asphyxia, low birth weight, sepsis, prematurity, congenital anomalies Postnatal – toxins, trauma, infection
DIAGNOSIS • Early diagnosis is difficult. • Motor Examination • - traditional neurologic exam • - assessment of primitive reflexes • - elicitation of postural responses
MANAGEMENT • Cerebral palsy is not curable. • Goal of therapy is aimed at: • - maintaining function (secondary prevention) • - maximizing or developing new functions
ACTIVITIES DIRECTED TOWARD MAINTENANCE OF FUNCTION • Motor therapy to prevent contractures. • Positioning to ensure symmetry and prevent scoliosis.
ACTIVITIES … • Assistive devices (walkers, poles, standing frames, wheelchairs) • Surgical procedures • - adductor tenotomy or psoas transfer • - tenotomy of the Achilles tendon • - dorsal rhizotomy
NON-MOTOR ACTIVITIES DIRECTED TOWARD MAINTENANCE OF SELF-ESTEEM AND PREVENTION OF SECONDARY BEHAVIORAL DISTURBANCES • Parental counseling for appropriate expectations • School placement consonant with the child’s abilities • Opportunities for social interaction
ASSOCIATED HANDICAPS IN CP • Seizure disorder • Mental retardation • Visual problems • Hearing disorders • Feeding problems • Dental problems • Speech/language problems • Behavioral problems
