Teachable Moment: SFEMG Normal Jitter-Video

Video Transcription

Video Summary

In the video, Dr. Goyal discusses single fiber EMG with a concentric needle. They present a case of a 19-year-old female with left ptosis and generalized fatigue. After various tests, including negative antibody results, it is determined that she does not have a significant decremental response nor a clinical response to pertostigmine treatment. Single fiber EMG is shown as a valuable tool in diagnosing neuromuscular junction transmission disorders. Jitter, the variation in neuromuscular junction transmission time, is analyzed using 20 fiber pairs collected for each sampled muscle. Single fiber EMG can provide valuable information for diagnosing these disorders. credits: www.ottobock.com
