Medical Student: EMG Basics-2022 Basics of NCS and Needle EMG

Video Transcription

Video Summary

Dr. Eisenberg delves into needle EMG basics and muscle activity analysis, explaining differences in morphology and firing patterns in various conditions. He discusses recruitment patterns and provides examples of normal and abnormal motor unit action potentials in neurological conditions. Dr. Choi focuses on technical errors in nerve conduction studies, highlighting the impact of temperature and common pitfalls like submax stimulation and anomalous innervation. Practical tips to improve accuracy include starting with low intensity, observing morphology changes, and confirming anomalies with additional muscle studies. Understanding these aspects can enhance the interpretation of muscle activity and improve diagnostic accuracy in neurological conditions.
