An Advanced Practice Providers 101 Guide to PM&R-APP – PM&R Diagnostics

Video Transcription

Video Summary

The video discusses the basics of electrodiagnostics, specifically EMG (electromyography), and nerve conduction studies. The presenter explains that EMG is a test of the peripheral nervous system and an extension of the history and physical exam. Nerve conduction studies involve stimulating a nerve and measuring the parameters of the action potential it creates. The video also covers the interpretation of the EMG and nerve conduction studies, including identifying different types of nerve damage and patterns seen in the EMG waveform. The needle EMG portion involves inserting a needle electrode into a muscle and measuring the voltage in real-time. The video emphasizes that the interpretation of electrodiagnostic tests is not perfect and must be considered in the context of the patient's clinical presentation. Overall, the video highlights the utility of EMG for diagnosing peripheral nervous system disorders, but acknowledges its limitations.
