This Checkpoint explains the basic pathophysiology of axon loss, demyelination, and conduction block; identify the corresponding nerve conduction patterns for axonal and demyelinating processes; recognize the most common anomalous innervations in the upper and lower limbs; describe the nerve conduction techniques used to confirm the presence of an anomalous innervation. The AANEM designates this enduring material for a maximum of 3 CEUs and 1 Checkpoint credit toward CNCT recertification.

To receive the CNCT Checkpoint credit, a post-test must be completed with a 70% passing rate within 3 attempts.

FORMAT: Recorded virtual meeting session from 2021 Spring Conference.
