Flashcards in Quiz 3 - weakness evaluation Deck (13):
contrast weakness in proximal vs distal muscles
proximal - more likely to be a myopathy
distal - more likely to be a generalized polyneuropathy
if limb weakness is associated with lower facial weakness on the same side.....
lesion above the brainstem
facial weakness contralateral to limb weakness
if repeated activity tends to worsen the symptoms...
movements or postures bring on weakness....
orthopedic or mechanical problem
four origins of weakness
- upper motor neuron
- lower motor neuron
- muscle itself
PE of upper motor neuron diseases
- broad areas of body
- heightened deep tendon reflexes
- minimal atrophy
- minimal fasciculations
- possible spastic tone "clasped knife"
PE of lower motor neuron diseases
- decreased tone
- decreased reflexes
PE of neuromuscular disease
- fluctuating strength based on muscle use
PE of myopathy
- proximal and symmetrical
- no atrophy
- normal reflexes at first
muscle disease often results in increased....
- creatinine kinase
antibodies against ACh receptors can indicate....
