Quiz 2 Flashcards
definition of CP
group of permanent disorders of movement/posture development that causes activities limitations that are attributed to non progressive disturbances that occurred in the developing brain
what does CP look like
plegia
spasticity
dyskinesia
ataxia
mixed
how common is CP
most common physical disability of childhood (2 per 1000) births
how is CP diagnosed
clinical and neuro signs
what age is CP diagnosed at
12-24 months
motor types for CP
spasticity
dyskinesia
ataxia
mixed
hypotonia
most common motor type for CP
spastic
limbs affected in spastic quadriplegia/ bilateral
both arms and legs
trunk face and mouth can also be affected
limbs affected in spastic diplegia/ bilateral
both legs
limbs affected in spastic hemiplegia unilateral
one side (arm and leg)
GMFCS level 1
kids walk and climb stairs w/o limitations
can run and jump but speed, balance and coordination are impaired
GMFCS level 2
kids walk and climb stairs holding onto railings. limitations on uneven surfaces and includes and in crowded spaces
GMFCS level 3
kids walk on level surface with AD. May climb stairs w/ railing. May propel WC manually or transported for longer distances
GMFCS level 4
kids may walk short distances on a walker and relay on wheeled mobility at home and in community
GMFCS level 5
restricted voluntary control of environment and ability to maintain anti gravity head and trunk posture. all areas of Motor control limited. transported, no independent mobility
common co morbidities of CP
inability to walk, inability to talk, pain, epilepsy, behavioral disorders, intellectual impairment, vision impairment, bladder control problems, sleep disorders, salvia control
types of etiology of CP and occurance
prenatal 80%
post natal 10%
peri natal 10%
risk factors for CP
low birth weight
premature birth
multi births
maternal conditions
prenatal infections/ toxin exposure
perinatal: breech birth, complication LD
postnatal: meconium aspiration
what is the leading cause of CP in preterm infants
periventricular leukomalacia
what is PVL
damage to white matter
what is IVH or ICH
bleeding in brain d/t weak or fragile blood vessels
does genetics play a role in CP
yes
symptoms of IVH
apnea
bradychardia
cyanosis
weak suck
high pitch cry
seizures
swelling/ bulging of fontanelles (soft spots)
anemia
perinatal causes of CP
birth asphyxia
hypoxic ischemic encephalopathy
neonatal stroke
postnatal causes of CP
non-accidental injury
head trauma
meningitis/encephalitis
cardiopulmonary arrest
is CP an UMN or LMN problem
UMN patho
where do UMN synapse onto LMN
ventral (anterior) horn of SC
where do UMN travel through
pyramidal tracts
+ signs of UMN lesion
muscle spasticity d/t reduced descending inhibitory signals from brain
- signs of UMN lesion
weakness of loss of dexterity d/t reduced descending excitatory signals from brain
do lesions of extrapyramidal tracts cause UMN signs?
no b/c they modulate and refine movement
