2021 Workshop Handout Bundle-Cranial NCS and EMG Testing

Cranial NCS and EMG Testing - Kimura

Pdf Summary

This document is a text summary of an AANEM workshop on cranial nerve conduction studies and electromyography (EMG). The workshop was presented by Dr. Jun Kimura from the Department of Neurology at the University of Iowa Health Care. The document provides an introduction to the testing of cranial nerves, with a focus on the trigeminal, facial, accessory, hypoglossal, and other cranial nerves. It also discusses the anatomical considerations and techniques for stimulation and recording of the facial, trigeminal, accessory, and hypoglossal nerves. The document explains the clinical applications of blink reflex testing, including its use in diagnosing trigeminal neuropathy, Bell's palsy, synkinesis, hemifacial spasm, acoustic neuroma, and polyneuropathy. It also discusses the use of electromyography in studying cranial muscles, including the face, masseter, trapezius, sternocleidomastoid, tongue, and genioglossal muscles. The document provides tables and figures to illustrate normal values, abnormalities, and findings in various neurological conditions.
