Specifics about each Level and each Item:
What you do you need to know:
Level 2
• Uses appropriate terminology
related to NCS/EMG
Nerve conduction studies
(motor and sensory amplitudes, latencies, conduction
velocities)
Late responses (F responses
latencies, H reflex amplitudes and latencies)
Repetitive nerve
stimulation (slow rate, rapid rate, post-exercise
evaluations)
Needle electromyography (EMG)
testing (motor unit action potential amplitude,
duration, polyphasia and stability; motor unit action
potential recruitment and activation)
Level 3
•
Describes NCS/EMG data
Axonal loss and
reinnervation (acute, subacute, chronic)
Demyelination and
conduction block/slowing (acute, chronic, acquired,
inherited)
Neuromuscular junction
defects (pre- and post-synaptic)
Myopathies (acute, chronic,
associated with denervation, associated with myotonia)
•

Physiologic and non-physiologic technical factors (age,
height, temperature, supramaximal stimulation, volume
conduction)
