Checkpoint: Basic NCS Physiology & Annomalous Innervations-Dr. Jordan Presentation

Dr. Jordan Presentation

Pdf Summary

The document appears to be a detailed course outline for a session on nerve conduction studies in 2024, focusing on axonal injuries, demyelination, and conduction blocks. Presented by Dr. Daniel B. Simmons and Dr. Morgan Jordan, the course is part of the offerings at an academic medical meeting. <br /><br />**Learning Objectives:** <br />1. Explain the pathophysiology of axonal injuries, demyelination, and conduction blocks.<br />2. Identify nerve conduction patterns for these conditions.<br />3. Recognize common anomalous innervations in limbs.<br />4. Describe techniques for confirming anomalous innervations.<br /><br />**Course Structure:**<br />- Part 1: Nerve Conduction Physiology<br />- Part 2: Anomalous Innervations<br />- Part 3: Application through Cases<br /><br />**Key Content:**<br /><br />1. **Nerve Anatomy and Physiology:** <br />   - Overview of axons, myelin, and nerve components such as motor and sensory fascicles. <br />   - Normal sensory and motor function pathways are depicted.<br />   <br />2. **Types of Nerve Injuries:**<br />   - **Axonal Injuries:** Characterized by reduced amplitude/area in conduction tests due to axon loss (Wallerian degeneration) with preserved conduction velocities.<br />   - **Demyelination:** Leads to slow conduction velocities and prolonged latencies, with normal amplitude/area, enabling lesion localization.<br />   - **Conduction Block:** Failure of conduction due to demyelination causes transmission failure and amplitude reduction proximally.<br /><br />3. **Assessment Techniques:** <br />   - Emphasizes interpreting conduction velocities and latencies in diagnosing these conditions.<br /> <br />4. **Clinical Cases & Feedback:**<br />   - Participants encouraged to provide feedback via the AANEM app for continuing education credits and future course improvements.<br /><br />The session aims to improve understanding of nerve conduction abnormalities, with practical and theoretical insights for medical practitioners specializing in neurology or related fields.
