Flashcards in [MND] Cerebral Palsy Deck (19):
Epidemiology: Cerebral Palsy
2 to 2.5 / 1000 live births in NZ
Approximately 7000 people have a degree of cerebral palsy in NZ (1/3 are under 21 years old)
Pathophysiology of CP?
The initial neurological lesion the child sustains is non-progressive as it remains unchanged; however the effects of the lesion on other systems such as the musculoskeletal system can be progressive
The clinical presentation of Cerebral Palsy is dependent on
The area and extent of the CNS affected
A reduced life expectancy (90% survival rate into teens and 20s)
Immobility and severe learning difficulties are considered influencing factors
Ataxic Cerebral Palsy?
@ the cerebellum
- Affects 5-10% of the cases
- Characterised by low muscle tone and poor co-ordination of movements
- Affects the sense of balance and depth perception (resulting in poor co-ordination, unsteady, wide based gait)
The Gross Motor Function Classification System (GMFCS) is an outcome measure for..
cerebral palsy; it is a classification tool with five levels based on the child’s ability to perform gross motor skills and assistance required when mobilising in a variety of conditions (i.e. stairs, distances, altered terrain)
Cerebral Palsy can be described as
A group of disorders primarily affecting the development of movement and posture causing limitation of activity
In CP, what percent does hemiplegia account for?
Dyskinetic Cerebral Palsy is a lesion located @? What are the movements like?
The basal ganglia (10-20% of cases)
Movements are uncontrolled, purposeless, slow, writhing movements
Based on patient history and physical examination. CT and MRI can be useful when the aetiology (cause) has not been established
Constraint-Induced movement therapy can improve functional ability in the affected upper limb and aid cortical reorganisation and can be useful for
What are some causes / risk factors for CP?
Multiple Pregnancy (i.e. twins/triplets)
Low and very low birth weight (50% of cases, 30% increase in risk)
Foetal malformation syndromes
About 10% cases of CP is 'Mixed Cerebral Palsy' which means
Several areas of the brain are involved
Spasticity in the arm, leg and trunk on one side, underdevelopment of the affected side (smaller limbs/leg shortening), equines of foot and ankle, flexion of elbow, wrist and fingers
All this sounds like what kind of CP?
In CP, symptoms are developed before or during the...
First year of birth
Orthotics can be used to ....
What are a some types of CP this might be useful for?
maintain leg length, prevent further deformity, improve joint alignment, improve biomechanics and function
(can be useful for spastic diplegia / hemiplegia / quadriplegia)
Lesion locations of CP
Premotor / motor cortex = Spastic
Cerebellum = Ataxic
Basal Ganglia = Dyskinetic
What guidelines can we use for strength training for CP?
ACSM guidelines - 3x8-12 reps; 2x a week; light to moderate load
