Clinical Neurophysiology Flashcards
1
Q
What tests are involved in neurophysiology?
A
Nerve conduction studies/ Electromyography (EMG)
-To investigate problems of peripheral nerve and muscle
EEG
-Electrical activity within the brain, investigate epilepsy and states of altered consciousness
Evoked potentials
-Visual and somatosensory, investigate problems in central pathways
2
Q
What are nerve conduction studies?
A
To examine nerve function
- Conduction velocity
- Amplitude
3
Q
What is ulnar neuropathy?
A
Most often at the elbow (occasionally at the wrist)
Ulnar distribution numbness
(note dorsal cutaneous branch)
Wasting of small muscles (esp FDI)
4

A
Myaesthenia gravis
5
Q
