Nsp Week 2: Neuromuscular Electrodiagnostic Tests (Desousa)

Front 1

What type of date is captured on NCS?

Back 1

1. Latency from stimulus to record (time)
2. Amplitude of action potential
3. Conduction velocity

Front 2

What are some common abnormalities seen with NCS?

Back 2

1. Prolonged latency
2. Reduced/absent action potential amplitude
3. Slow conduction velocity

Front 3

List 5 indications for performing NCS with needle EMG

Back 3

1. Peripheral neuropathies
2. Brachial/ lumbosacral plexopathy
3. Cervical/ lumbosacral radiculopathy
4. Myopathy
5. Motor neuron disease

Front 4

What is the indication for repetitive nerve stimulation studies?

Back 4

Neuromuscular junction disorders

Front 5

If repetitive nerve stimulation test is normal, what test is indicated next?

Back 5

Front 6

What type of data is acquired from needle electromyography?

Back 6

1. Motor unit action potential (MUP)
2. Recruitment pattern

Front 7

Needle electromyography is useful in the diagnosis of which 3 groups of disease?

Back 7

1. Myopathies
2. Neuropathy and radiculopathies
3. Motor neuron diseases

Front 8

Small and short duration MUPs detected by needle electromyography may indicate what type of disease?

Back 8
