Q
What happens when the cerebral cortex or internal capsule is damaged immediately?
A
Hyporeflexia Hypotonia Loss of monosynaptic reflexes Flaccid paralysis of contra lateral limb BUT THEN THIS REVERSES
1
Q
What are the classical signs of UMN syndrome?
A
Hypertonia with spasticity
Hypereflexia
Paralysis or weakness of movement of muscles affected
Abnormal reflexes eg. Babinski sign
2
Q
What can be damaged to cause UMNS?
A
Cerebral cortex Internal capsule Crus cerebri Lower medulla Lateral funiculus of spinal cord
3
Q
What are the classical signs of lower motor neurone lesions?
A
Muscle weakness Muscle wasting Loss of tone Absent or decreased reflexes Fasciculation
4
Q
What are lower motor neurone lesions caused by?
A
Trauma
Peripheral neuropathy
MND
Diabetic neuropathy
5
Q
What is hypotonia?
A
Decreased muscle tone
6
Q
What is atonia?
A
No muscle tone
7
Q
What is hypertonia?
A
Too much tone
The agonists and antagonists are equally stiff which leads to spastic paralysis
