Question 1
During a median motor NCS, you stimulate at the wrist and record from APB. The distal motor latency (DML) is 5.2 ms (reference
Correct Answer:
Focal demyelination of the median nerve across the carpal tunnel (consistent with median neuropathy at the wrist / CTS)
Question 2
On needle EMG of the abductor pollicis brevis (APB), you observe positive sharp waves and fibrillation potentials at rest, decreased recruitment, and long-duration polyphasic motor unit action potentials (MUAPs) with high amplitude. Which is the most likely underlying process?
Correct Answer:
Chronic neurogenic process with active denervation and reinnervation
Question 3
Which is the most accurate description of how to differentiate a C7 radiculopathy from a brachial plexopathy involving the middle trunk on needle EMG?
Correct Answer:
Paraspinal muscle abnormalities (multifidus) localize to the root level; plexopathy typically spares paraspinals
Question 4
A patient presents with bilateral foot drop, areflexia, and rapidly progressive weakness 2 weeks after a GI infection. NCS show prolonged F-wave latencies and conduction block in multiple nerves. What is the most likely diagnosis?
Correct Answer:
Guillain-Barre syndrome (acute inflammatory demyelinating polyradiculoneuropathy)
Question 5
Which best describes appropriate use of the H-reflex?
Correct Answer:
Tests the S1 reflex arc by recording from the gastrocnemius/soleus after stimulation of the tibial nerve; useful in evaluating S1 radiculopathy
