Q
Down Syndrome treatment
A
- emphasize exercise and fitness, stability
- maximize respiratory function
- family/caregiver education
- possible surgical intervention for cardiac abnormalities
21
Q
Duchenne Muscular Dystrophy (DMD)
A
- progressive disorder caused by absence of gene required to produce muscle proteins (dystrophin and nebuilin)
- Fat/CT eventually replace muscle
- Typically die in teens due to cardiopulmonary failure
22
Q
DMD etiology
A
- Genetic disorder**- x-linked recessive trait
- mother is “silent carrier” and only males will manifest the disease
23
Q
DMD s/sx
A
- Symptoms usually manifest between 2-5 years old
- progessive weakness
- Falling
- toe walking
- excessive lordosis
- pseudohypertophy of muscle groups (calf)**
- Progressive impairment with ADLs and mobility around age 5 => eventual inability to walk
24
Q
DMD PT treatment
A
- respiratory function
- submax exercise**
- mobility skills
- splinting
- orthotics
- adaptive equipment
- family/caregiver education
- med management: immunsuppresants, steroids
25
Prader-Willi Syndrome diagnosis
Diagnosed by physical attributes and behavior patterns
26
Prader-Willi Syndrome Etiology
Partial deletion of chromosome 135
27
Prader-Willi Syndrome s/sx (physical and behavioral)
- Physical characteristics: small hands, feet, and sex organs, hyotonia, almond-shaped eyes, obesity, incoordination, intellectual disability
- Behavioral characteristics: constant desire for food*
28
Prader-Willi Syndrome Treatment
- Postural control
- Exercise and fitness
- Gross and fine motor skills training
29
Spina Bifida
Developmental abnormality d/t failure of neural tube closing by 28th day of gestation
30
Spina Bifida Etiology
Multiple factors, but attributed to insufficient folic acid intake by mother
31
Spina Bifida Classfications (2)
1) Spina Bifida Occulta
| 2) Spina Bifida Cystica
32
Spina Bifida Occulta
- Non-fusion of the spinous processes of vertebrae, but spinal cord and meninges stay intact
- No associated disability
33
Spina Bifida Cystica
- Cyst-like protrusion through the unfused vertebrae
| - Results in impairment; worse prognosis than SB Oculta
34
Forms of Spina Bifida Cystica (2)
1) Spina Bifida Cystica Meningocele
| 2) Spina Bifida Cystica Myelomeningocele
35
Spina Bifida Cysta: Meningocele
- Herniation of meninges and CSF and meninges into a sac that protrudes through the vertebral defect
- Spinal cord remains within the canal
36
Spina Bifida Cystica: Myelomeningocele
- Severe form
- Herniation of meninges, CSF, and spinal cord extending through defect in the vertebrae
- Cyst may or may not be covered in skin
37
Spina Bifida Cystica: Myelomeningocele s/sx
- motor loss bleow level of defect in spinal cord
- sensory deficits
- hydrocephalus**
- Arnold-Chiari Type II malformation
- osteoporosis
- clubfoot**
- scoliosis
- tethered cord syndrome
- latex allergy**
- bowel/bladder dysfunction
- learning disabilities
38

39
Spinal Muscular Atrophy (SMA)
Progressive degeneration of the anterior horn cells
40
SMA Etiology
Autosomal recessive inheritance (mutation of chromosome 5)
41
Types of SMA (3)
1) Acute Infntile SMA: life expectancy < 1 year
2) Chronic Childhood SMA: Steady impairment, though child can survive into adulthood
3) Juvenile SMA: Occurs later in childhood (4-17), typically survive into adulthood
42
SMA s/sx (same regardless of type)
- Vary in onset/speed of progression
- Progressive muscle weakness and atrophy
- Diminished/absent DTRs
- End-stage respiratory compromise**
- Sensation and cognition unimpaired**
43
SMA treatment
