review of basic EMG concepts

Study Slideshow

A 24 year old student has persistent low back pain and left calf weakness after a fall 3 weeks ago. You suspect S1 radiculopathy. Name 3 muscles will likely show denervations

paraspinals, gastroc, hamstrings, gluts, TFL

This waveform was seen in the TFL during EMG in a 60 y.o. what is the likely diagnosis? acute radiculopthy, chronic radiculopathy, myopathy,

myopathy

Patient has numbess in the RIGHT thumb. Which 3 muscle will you test to differentiate C6 radiculopthy from CTS

paraspinals, deltoid, biceps, brachiorad, pronator teres

This wave is waxing and waning and noted in the various proximal upper and lower extremities of a 20 y.o muscular man who denies signficant weakness. What is the most likely diagnosis

myotonia congenita, Herculean

Facial Myokymia is most likely seen in which disorder?

post radiation plexopathy , brain stem lesion, MS, thyroid toxicosis

This is seen with LEFT side stim. What is the diagnosis?

R CN 7 pathology

Describe 3 characteristics of a typical H-reflex testing and response ( stim intensity/duration, waveform consistency)

submax, long duration, consistent waveform morphology and motor

Which part of the NCS waveform is useful for calculating conduction velocity ( phases, amplitude, peak latency, onset latency)

onset latency

How can fibrillation potentials be differentiated from end-plate-spikes

Fibrillation as initial downward (positive) deflection and end plate spikes have initial negative deflection

Which 3 abnormal spontaneous potentials arise from single muscle fibers

fibs, sharps, mytonic

Which 3 muscles are supplied by the anterior Interosseous Nerve

FDP (lateral half), FPL, pronator quadratus

EMG testing of which muscle can help you differentiate ulnar compression at the cubital tunnel vs injury at the plexus

FCU

What happens to the waveform when you reduce the high frequency filter from 10 KHz to 5 KHz

reduce onset, reduce peak onset, reduce amplitude
