The child with Cerebral Palsy part 1
Question | Answer |
---|---|
What is cerebral palsy | CP is an umbrella term that describes disorder of monements, posture and motor funciton resulting from a nonprogressive lesion/abnormality of the developing brain |
what is the life expectancy for a child with cp | mild/moderate = normalsevre = shortend lifespan |
what are the causes of CP | Prenatal (15%)- viral infection- metabolic- vascular occlusionPerinatal (15%)- hypoxia secondary to acidosispost natal (10%) |
what are common motor aspects of CP (7) | 1mm weakness2delayed motor development3.lack of selective control4.sterotypical movemnt patterns and postures5.alterations in mm tone6. sensory impairment7. balance and anticipatory postural losses |
what other associated impairments can exist with CP | visual, auditory, language delay, (65%) hearing and epilepsy |
what are the three areas of cp classification | 1. motor type 2.topography 3.level of motor function |
what are the 5 motor types of cp | 1.spactic (corticospinal)2.dyskinetic (basal ganglia)3.ataxic (cerebellar)4. hypotonic5.mixed |
describe spastic cp | Spactic cp involves the corticospinal area. increased in velocity dependant resistance to passive mvt. altered timing and activation of mm |
describe dyskinetic CP | Dyskinetic CP occurs with basal ganglia is effected. results in dystonia (exaggerated mvt) and athetosis (writing movements) |
describe ataxic cp | where cerebellar mainly affected resulting in difficulty with timing and coordination |
what are common effects of ataxia (8) 4drhin | dysmetria, dyssenergia, diadokinesia, disarthria,Rebound phenomenon, Hypotonia, intention tremmor, nystagmus |
descrbe the classifcation of topography with cp | either unilateral (one side of body) with monoplegic (one limb) or hemiplegic (one side) or bilateral (both sides of body) diplegia (both arms or legs) quadraplegia all four limbs |
what is the prognosis for walking for a child with CP | - (I) sitting by 2 = walking- if not by 4 then no walking- maximum ambulatory status acheived by 7- Intelectual impriments delays walking |
what is the prognosis for hemiplegic cp | 100 walking by age 3 |
what is the prognosis for diplegic cp | variable but 95% ambulate with/without aid during lifetime |
