Spina bifida is a defect in the development of the _____________?
Neural tube
Spina Bifida Occulta
What is the etiology of SB?
Genetics (usually polygenic and modified by environment), embryologic component, and environmental- folic acid deficiency!
Define CP
non-progressive disorder of movement or posture of early onset (i.e. the developing nervous system) due to damage to brain (not spinal cord)
List 4 of the disorders/deficits commonly seen with CP
Voluntary motor (always affected), sensory, intellectual, speech, audition, seizures, visual, growth abnormality
What is the time range during development in defects may occur that lead to SB?
Day 17-26
What is syringomyelia?
You are treating a patient with a Hx of Arnold Chiari malformation. What are some primary concerns you need to be aware of as their PT?
Possible latex allergy, S&S of shunt dysfunction, possible learning difficulties (may affect your pt. education delivery), Hx of seizures and how they detect if a seizure is coming (if they are able to)
True or false - CP is a progressive disorder?
FALSE!!!!!!
True or false - CP can be caused by a anoxic brain injury at 12 mo.s of age
TRUE!
Myelomeningocele- meninges and SC herniate, results in complete or partial paralysis, usually surgery is performed
Meningocele- only meninges herniate, SC is in place and intact
SB occulta- defect of vertebrae- no herniation, may have hairy patch or dimple over area, increased chance of tethered cord
Lipomeningocele- closed neural tube defect, fatty tissue in sac and/or SC that may result in compression to the SC
Diastematomyelia- closed neural tube defect usually, longitudinal splitting of the SC that leads to abnormal neurological function
What is Chiari Type II defect and what is its clinical significance?
Your patient wants to have a child but is scared of her child having spina bifida. She asks you if there is anything she can do to prevent it from happening? She has no history of SB in her family. Her sister in law is also wondering since she had one child previously that was born with meningocele. What would you tell them?
Your patient- take 0.4 mg/day of folic acid
The sister in law- take 4.0 mg/day of folic acid- recurrence rate is 71% though
Tell them both to start taking it 1-3 months before pregnancy and during the first 3 months of pregnancy
What can you say about intellectual involvement with regard to severity of the CP?
More severe CP is more likely to involve IQ
Describe how a patient with spastic diplegia would present.
Increased muscle tone/spasticity seen in the LE bilaterally
-Increased head size
-Vomiting
-Swelling at shunt site
-Headache
-Irritability
-Seizures
-Lethargy
-Change in school performance
-Rapidly progressive scoliosis
Describe the S&S of tethered cord syndrome
-Increased or "new" spasticity
-Change in bowel or bladder status after ruling out UTI, constipation
-Back pain
-Changes in foot position
-Development of hamstring contracture
-Progressive scoliosis
Athetoid CP would be caused by an injury to which part of the brain?
List 5 prenatal factors that can be associated with CP
Malnutrition, lack of growth factors intrinsically, infection (herpes, rubella, toxoplasmosis), anemia, Rh incompatible, fetal anoxia, maternal diabetes, genetic/heredity cause
A 4 year old patient presents to your clinic with spastic hemiplegia. What are some signs and symptoms you would expect to see?
Early handedness, persistent fisting of one hand, ipsilateral toe walk, UE>LE involvement, compensation with unaffected side
You work at an OP Ortho site. You have an eval today with a 15 y.o. complaining of excessively tight hamstrings, back pain, and sudden spinal imbalance. When examining his spinal ROM, you notice a hairy patch around L2 level. What is the likely the cause of the pain and what will you do?
List the possible consequences of Chiari Type II?
Hydrocephalus, brainstem dysfunction, upper cervical cord dysfunction, learning disabilities, seizures, and growth problems
List 2 predictive signs regarding ambulation
Sit independently by age 2 (yes), not sitting independently by 4 (no), 3+ primitive reflexes beyond 2 (no).
What is periventricular leukomalacia?
Damage to the white matter of the brain in the long axons near the ventricles
Describe the diagnostic process of CP
No definitive test. Look at motor performance and milestones. Presentation of altered/abnormal tone, posture, reflexes. Rule out other diagnoses.
