CP Prevalence
1 - 5/1,000 births worldwide
2/1,000 Europe
3/1,000 US
What is the trend in Prevalence of CP
Decreasing in Preterm
Stable in term
Combined stable
4 Perinatal risk factors for CP
Prematurity
Breech
Birth complications (placental detachment, cord, uterine rupture)
Birth asphyxia (<10%)
3 Postnatal risk factors for CP
Trauma
Infection
Coagulopathies (sickle cell, clotting deficiencies, etc.)
Which is true regarding CP
- Prenatal factors major
- Labor causes high %
- Premature no longer a problem
- Most CP children premature
- Prenatal is major contributor
- Labor <10%
- Premature strongest risk factor
- Most children with CP are born at or near term
Neuroimaging in CP
- 90% abnormal
- Most commonly prenatal
- Destructive 90% (normal brain insulted with PVL or deep grey matter injury)
- Brain Mal-development 10%
- Normal Neuroimaging 10%
Classification: Motor CP
Spastic: 80%
Dyskinetic: 10% (Athetosis, Chorea, Dystonia)
Ataxic/hypotonic: 10%
What Cobb angle is cut-off for scoliosis fusion
> 40 to 50 degrees
Risk factors for hip migration in CP
Malalignment (valgus neck shaft angle) Femoral anteversion Decreased weight-bearing Spasticity Weakness of hip abductors and extensors
Which of the following contributes to hip subluxation in CP:
- Congenital hip dysplasia
- Overactive gluteus medius and minimus
- Weakness of adductors
- Femoral anteversion and coxa valgus
- Femoral anteversion
Risk factors for poor bone health in CP
- nutrition and absorption
- decreased exposure to sun
- non-ambulatory
- anti-seizure meds
What is the z-score in DXA scans for Osteoporosis in children
z-score <2.0
What is used for DXA scan measure for children
z-score
Not T-score
Distal Femur
CP Low Bone Density Fractures
Prevalence: 20% for non-ambulatory Patients
7-9.7% per year incidence for severe CP
Most common distal femur
3 Means of prevention of low bone density in CP
- proper nutrition and calcium intake
- vitamin D
- Increase weight bearing
Optimal use of DEXA in CP
- scan hip or L-spine
- avoid scan in fracture area
- Low bone density is Z-score -2 or below
- low bone density T-score 2.5 or below
- Low bone density CP defined at Z-score < 2
Spasticity
Increased resistance to velocity dependent stretch
Modified Ashworth Scale
0 - normal 1 - slight catch 1+ - slight catch with continued increased in resistance 2 - resistance through full ROM 3 - considerable increase in resistance 4 - rigid
Tardieu Scale
R1 - first catch
R2 - end range
Hypertonia Assessment Tool (HAT)
7 item tool to differentiate spasticity, dystonia, and rigidity
Barry-Albright Dystonia Scale (BADS)
5 point dystonia scale
specific areas of the body covered.
Definition of Dystonia
Dystonia is a movement disorder in which involuntary sustained or intermittent muscle contractions cause twisting and repetitive movements, abnormal postures, or both
Definition of Chorea
Chorea is an ongoing random-appearing sequence of one or more discrete involuntary movements or movement fragments
Definition of Athetosis
Athetosis is a slow, continuous, involuntary writhing movement that prevents maintenance of a stable posture
Definition of Myoclonus
Myoclonus is a sequence of repeated, often nonrhythmic, brief shock-like jerks due to sudden involuntary contraction or relaxation of one or more muscles
Definition of Tremor
Tremor is a rhythmic back-and-forth or oscillating involuntary movement about a joint axis
Definition of Tics
Tics are repeated, individually recognizable, intermittent movements or movement fragments that are almost always briefly suppressible and are usually associated with awareness of an urge to perform the movement
Name 4 lower extremity functional measures for CP
- Instrumented and clinical gait parameters
- Gross Motor Function Measure (GMFM)
- GMPM
- 6 minutes walk test
