Cerebral Palsy Flashcards
Demographics:
- Incidence 1.5 – 5 per 1000 live births
- Prevalence 2.4 per 1000 children starting school age 6
- M:F - 1.33:1
Aetiology - 2 main lesion types
- Periventricular leukomalacia – preterm babies – drugs, alcohol, infection, blood disorders
- Stroke – in term babies – infection, blood coagulation disorders
Pathophysiology
Periventricular leukomalacia - White mater around ventricles ends up being soft and starts dying off in patches. The more damaged patches the more dramatic the signs and symptoms
Factors for perinatal stroke:
- Drug Abuse
- Infection
- Thrombophilia in mother
- Labour and delivery complications
How does PVL affect the development of the motor system?
PVL disrupts the connection between the thalamus and the cortex - causing motor deficits. Evidence that this disruption had a stronger correlation to motor deficits compared to damage to the corticospinal tract.
How does perinatal stroke affect the development of the motor system?
- Uni-lateral Lesion causes competitive withdrawal – This is when the non-infarct side compensates for the deficits in the infarcted side.
- Bilateral lesion does not cause competitive withdrawal – because both sides of the brain is damaged.
Signs and Symptoms of CP:
- Deficits of motor control
- Excessive Muscle tone – UE flexors and LE Extensors (30% athetoid and 70% spastic)
- Hyperactive reflexes
- Characteristics of movement deficit – (changes in gait all the time) high variability in movement patterns
- Dysarthria
- Low IQ (
Conventional therapy of CP:
- • Treat motor symptoms as they appear
- • Treat other comorbidities
Role of exercise in CP:
- improvements in walking, jumping, or running
- improvement in psychological variables such as self-perception of physical appearance, athletic competence, and self-worth
- improvement in gait efficiency
Exercise for CP:
Short Intervals
Small progressions
What are the benefits of Exercise?
- increased participation in individual and community activities
- improved sense of well-being
- increased and maintained heart and lung efficiency
- maintained strength, flexibility, mobility and coordination
- improved and maintained bone structure
- assisted weight control
- reduced risks of chronic disease
