Q

_ _ _ is characterized by halting deliberate movements. Frequently seen in children with Myelomeningocele who also have hydrocephalus. 3 possible causes?

A

Upper limb dyscoordination

MMC

  • motor cortex or CS tract damage caused by hydrocephalus
  • motor learning deficits resulting from use of UE’s for balance and support rather than manipulation and exploration

Q

Spasticity: Muscle tone can be _ (LMN absent) or _ (LMN & UMN intact) or _ (UMN compromised, LMN intact) depending on? Spasticity is monitored to see if?

A

Muscle tone can be:

  • Flaccid (LMN absent)
  • Normal (LMN & UMN intact)
  • Spastic (UMN compromised with LMN intact)

Depending on the site of nervous system damage

Spasticity is monitored to see if neurological impairment is progressing.

17
Q

_ - _ % of spina Bifida patients have seizures. Can be due to associated brain _, _ malfunction or _.

A

10-30%

Can be due to associated brain malformations, shunt malfunction, or infections

18
Q

Musculoskeletal deformities can occur due to: poor _ _, coexisting _ _, imbalance of muscle pull due to _ _, reduced or absent _ _ motion, and deformities that develop after _.

A 
Poor intrauterine positioning
Coexisting congenital malformations
Imbalance of muscle pull due to neurological dysfunction
Reduced or absent active joint motion
Deformities that develop after fractures
19
Q

Scoliosis, Kyphosis, Gibbous, lower limb torsional deformities, hip dislocations, hip or knee flexion contractures, genu varus or valgus, equinovarus or valgus, and plantar flexion contractures are all examples of? Depending on?

A

Frequently seen musculoskeletal impairments depending upon the level of spinal cord involvement.

20
Q

Motor paralysis can present in 3 ways: Lesions resembling _ _ transactions, _ lesions with mixed presentation of _ and _ control, or _ (_) lesions with isolated function of _ _ the _ _.

A

3 Ways:
Lesions resembling complete cord transactions

Incomplete lesions with mixed presentation of spasticity and volitional control

Skip (sparing) lesions, with isolated function of muscles noted below the level of the lesion

21
Q

Neurogenic bowel/ bladder: requires careful _, including frequent _ _ to fully empty the bladder. May have _ complications later in life.

A

Requires careful management including frequent urinary catherization to fully empty the bladder

May have renal complications later in life

22
Q

_ is commonly seen in Spina Bifida patients, because torque generated by volitional muscle control is absent, and causes decreased _ _ _. Many sustain?

A

Osteoporosis

Causes decreased bone mineral density

Many sultan osteoporotic fractures

23
Q

Decubitus ulcers and other types of skin breakdown occur in -% of all children with Spina Bifida by the time the reach _ _. 4 most common causes?

A

85-95% of children by the time the reach young adulthood

4 most common causes (FUCT)

  • Friction, shear, burns
  • urine/ stool soiling
  • casts or orthotic devices
  • tissue ischemia from excessive pressure
24
Q

_ is also common mostly due to decreased activity and decreased muscle mass available to burn calories, especially after puberty.

A

Obesity

25
Q

_ _ occurs in up to 73%, compared to 1-5% in control group.

A

Latex allergy

Knee extensors:
Quads
Hip Adductors
Medial Hamstrings

31
Q

_ _ and _ are common musculoskeletal problems associated with mid-lumbar level involvement. Why?

A

Hip subluxation and dislocation
