A

A group of permanent disorders of the development of movement and posture, causing activity limitations that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain

Q

When is the definitive diagnosis for CP made?

A

After 12 months of age (some doctors wait until after age 2, delayed diagnosis due to neuroplasticity)

Q

What are the protective factors against CP?

A
  • magnesium sulfate
  • antibiotics
  • corticosteroids
22
Q

Spastic

A
  • most common

- increased resistance to passive movement which increases with increased velocity of movement

23
Q

Hypotonic

A

-some infants present with hypotonia with transition to spasticity or ataxia

24
Q

Dyskinetic

A

uncontrolled movement

25
Athetoid
slow, writhing movement
26
Ataxic
balance and control disorder
27
Diplegic? Hemiplegic? Quad/Tetraplegic?
``` Di = legs more affected Hemi = one side Quad = all 4 limbs ```
28
What are of the brain has been insulted to cause spasticity?
Cortex
29
What are of the brain has been insulted to cause athetosis?
Basal Ganglia
30
What are of the brain has been insulted to cause ataxia?
Cerebellum
31
What test is used to measure the severity of movement disability in CP?
Gross Motor Functional Measure (GMFM)
32
Describe the 5 levels in the GMFM
``` I = independent II = walks w/o AD; limited in outdoor and community level ambulation III = walk w/ AD; limited in outdoor and community level ambulation IV = self mobility w/ limitations; children are transported or use power mobility outdoors and in community V = difficulty controlling all movements, self mobility is severely limited even with the use of assistive technology ```
33
What is a hyperactive stretch reflex?
- decreased longitudinal growth of muscle fibers - decreased volume of muscle - change in muscle unit size and fiber type
34
Spasticity is seen in ___% of children with CP. The _____ Scale is used to assess spasticity, it ranges from ___ to ___.
75% Modified Ashworth 00-4
35
What items should be included in a comprehensive assessment for a child with CP?
- motor attainments - neurologic signs - primitive reflexes - postural reactions
36
What is the most common form of spastic CP?
Diplegia
37
What area of the brain is affected in diplegia? How is the infarct caused?
infarct in white matter of periventricular area, caused by hypoxia
38
What is the common presentation for diplegia? What Ads may be needed?
Crouched gait, usually normal cognition | Lofstrand crutches
39
What areas of the brain cause hemiplegia? What can cause hemiplegia?
- periventricular white matter abnormalities - cervical-subcortical lesions - brain malformations - nonprogressive postnatal injuries
40
What is the UE/LE positioning of hemiplegia?
UE: flexed LE: plantarflexion
41
What is the cognitive/social/emotional presentation for hemiplegia? ADs?
``` Cognitive = normal Social/Emotional = deficits present AD = min equipment requirements ```
42
What areas of the brain are affected in quadriplegia?
Periventricular white matter lesions - may affect basal ganglia - occipital area (leads to ataxia)
43
What are the cognitive effects in quadriplegia? ADs?
- variable cognitive effects | - requires significant equipment throughout lifespan
44
What terms are associated with dyskinetic CP?
- athetosis - rigidity - tremor - dystonia - ballismus - choreoathetosis
45
Where do lesions occur to cause dyskinetic CP?
deep gray matter lesions; sometimes periventricular white matter lesions
46
What are the effects to the c-spine in dyskinetic CP?
leads movements with jaw | C5-C6 hypermobile
47
What is the intelligence and medical needs for dyskinetic CP?
- normal to above normal intelligence | - more medical management than other forms of CP
48
What is the presentation of ataxic CP?
- difficulty w/ balance, control in the timing of coordinated movements - weakness - incoordination - wide based gait - noted tremor
49
Where are deficits located to cause ataxia?
cerebellum
50
What are some ways to treat patients with ataxic CP?
-making task specific activities, often have difficulty with transference of skills
51
Describe diplegic gait
- equinovarus - planovarus - crouch - jump knee - stiff knee - recurvatum - idiopathic toe walking
