Flashcards in Quiz 3 - weakness evaluation Deck (13):
1

contrast weakness in proximal vs distal muscles

proximal - more likely to be a myopathy
distal - more likely to be a generalized polyneuropathy

2

if limb weakness is associated with lower facial weakness on the same side.....

lesion above the brainstem

3

facial weakness contralateral to limb weakness

brainstem lesion

4

if repeated activity tends to worsen the symptoms...

myesthenia gravis

5

movements or postures bring on weakness....

orthopedic or mechanical problem

6

four origins of weakness

- upper motor neuron
- lower motor neuron
- NMJ
- muscle itself

7

PE of upper motor neuron diseases

- broad areas of body
- heightened deep tendon reflexes
- minimal atrophy
- minimal fasciculations
- possible spastic tone "clasped knife"

8

PE of lower motor neuron diseases

- decreased tone
- decreased reflexes
- atrophy
- fasciculations
- localization

9

PE of neuromuscular disease

- fluctuating strength based on muscle use

10

PE of myopathy

- proximal and symmetrical
- no atrophy
- normal reflexes at first

11

muscle disease often results in increased....

- creatinine kinase

12

antibodies against ACh receptors can indicate....

NMJ disease

13

most sensitive test for lower motor neuron damage

needle electromyography
