Plexopathy

1. What are the EMG findings in plexopathy?
2. How are the cords of the brachial plexus named?

Answers:
1. SNAP and CMAP depend on the site of the plexus injury. Late responses are possibly useful. EMG will have normal findings at the paraspinals, abnormal at the peripheral muscles.
2. Based on their relationship to the axillary artery.
