Q

What is the mechanism of injury for cerebral palsy?

A

Injury to the motor cortex neurons with decreases input to the spinal neurons

21
Q

What is the effect of injury to the motor cortex neurons?

A

Affects motor control
Decreases the number of effective units
Produces abnormal muscle control and weakness

22
Q

What are the signs and symptoms of cerebral palsy?

A

Known hypoxic or ischemic event
Muscle tone alterations
Delayed or failure to meet developmental milestones
Persistence of primitive reflexes

23
Q

What type of muscle tone alterations can occur with cerebral palsy?

A

Spasticity

24
Q

What is spasticity?

A

Stiffness of muscles

25
What is the recommended age for diagnosis of cerebral palsy?
3-5 years of age
26
Why is there a suggested delay in diagnosis for cerebral palsy?
Because signs and symptoms often change through child development. Some children "outgrow" their cerebral palsy
27
How does a physician examine a patient for cerebral palsy?
``` MRI/CT Spinal alignment Active and passive ROM in joints Motor power Muscle tone Movement disorders Limb deformities ```
28
What is the only way to definitively diagnose cerebral palsy?
Brain scan (MRI/CT)
29
What type of spinal abnormalities can occur as a result of cerebral palsy?
Kyphosis, lordosis, and scoliosis
30
What is kyphosis?
Excessive upper curvature of the spine
31
What is lordosis?
Excessive lower curvature of the spine
32
What is scoliosis?
Medial/lateral curve of the spine
33
How are gait abnormalities assessed?
Using the observational gait scale
34
What characteristics of gait are looked for using the observational gait scale?
``` Pez equinus Crouched gait Jumping gait Scissoring Windblown pelvis ```
35
What is pez equinus?
Excessive curling of the toes causing the individual to walk on top of their toes
36
What are some common arm deformities associated with cerebral palsy?
``` Shoulder internal rotation Elbow flexion Forearm pronation Wrist flexion Thumb in palm ```
37
What are some common leg deformities associated with cerebral palsy?
``` Hip flexion Hip adduction Knee flexion Ankle equinus Hindfood valgus Toe flexion ```
38
How can cerebral palsy be classified in terms of affected extremities?
Monoplegia, hemiplegia, diplegia, and quadriplegia
39
What is monoplegia?
Affects only one limb, usually an arm
40
What is hemiplegia?
Affects one side of the body including arm, leg, and trunk
41
What is diaplegia?
Affects symmetrical parts of the body (legs or arms)
42
What is quadriplegia?
Affects all four limbs
43
What are some non motor symptoms associated with cerebral palsy?
``` Epilepsy Speech impairment Vision Dental problems Poor nutrition Psychological and cognitive problems ```
44
Is there a cure for cerebral palsy?
No
45
How can cerebral palsy be treated?
``` Physical therapy Occupational therapy Speech therapy Botox CIT Dorsal Rhizotomy Tendon transfer/muscle lengthening ```
46
How can botox be used to treat cerebral palsy?
To relax spasticity of muscles
47
What is CIT?
Constraint Induced Therapy
48
How can CIT be used to treat cerebral palsy?
By placing a cast on the good limb to force use of bad limb in functional activities and train it
49
How can a dorsal rhizotomy be used to treat cerebral palsy?
By cutting off some of the sensory feedback coming to the dorsal root of the spine to dampen reflexes
