SEP interpretation

Somatosensory EP interpretation

Absence of all waves Peripheral nerve lesion, rule out technical problem
Absent EP with normal P14 and N20 Normal
Increased EP latency with equally increased P14 and N20 latencies; decreased peripheral nerve conduction velocity with normal central conduction time Peripheral nerve lesion, rule out technical problem
Increased clavicular-spinal conduction time with normal peripheral conduction and normal cervical-scalp conduction time Defect between the brachial plexus and the lower medulla
Absent cervical potential and abent or delayed scalp potential Defect between the brachial plexus and the somatosensory cortex
Increased cervical-scalp central conduction time with normal peripheral conduction and normal clavicular-cervical potential Defect above the lower medulla at or below the somatosensory cortex
Absent scalp potential with normal peripheral conduction and normal clavicular-cervical conduction time Defect between the lower medulla and the somatosensory cortex
Decreased peripheral conduction velocity and increased central conduction time Combination of peripheral nerve lesion and central defect
Increased latency of all SEPs at all levels Hypothermia; inaccurate measurement of distance between stimulating and recording electrodes

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
