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

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

Facial Myokymia is most likely seen in which disorder?

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

Which 3 abnormal spontaneous potentials arise from single muscle fibers

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

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

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

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

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

Which 3 muscles are supplied by the anterior Interosseous Nerve

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