Checkpoint: Basic NCS Physiology & Annomalous Innervations-Application Cases

Application Cases

Pdf Summary

The document appears to be a manual or study guide for electrodiagnostic testing, composed of various sections focusing on surgical and neurological cases presented in 2024. It includes detailed information on latency, amplitude, and conduction velocity for different nerves such as Radial-EIP, Peroneal-EDB, Median-APB, and Ulnar-ADM. Each section presents data followed by questions addressing the identification of different pathophysiological conditions such as demyelination, axon loss, or conduction block.<br /><br />Each practice case involves interpretation of nerve conduction studies to diagnose conditions like carpal tunnel syndrome or complex regional pain syndrome. For example, Case 1 discusses a 36-year-old female with foot drop, emphasizing the differences in conduction between various parts of the fibular nerve. It questions whether the underlying cause is axonal injury or conduction block. Case 2 handles hand paresthesias in a 37-year-old male suspected of having carpal tunnel syndrome, where users are prompted to determine whether demyelination, conduction block, or axonal loss is present. <br /><br />Case 3 covers a 55-year-old male with neck pain and potential radiculopathy, asking what abnormalities nerve conduction studies might show. Finally, Case 4 deals with "burning feet" syndrome in a 73-year-old female, which is primarily analyzed for its axonal or demyelinating nature.<br /><br />Additionally, the document invites readers to submit feedback via the AANEM app, and it reminds them to claim credits for their participation by a specific deadline. It also suggests utilizing tools like needle electromyography (EMG) to confirm diagnostic hypotheses. Overall, the text serves as an educational resource for medical professionals studying electrodiagnostic testing, stimulating analytical skills through real-world case scenarios.
