BrainWaves #90 Conduction block, and why it confuses me

MedLink Neurology Podcast is delighted to feature selected episodes from BrainWaves, courtesy of James E Siegler MD, its originator and host. BrainWaves is an academic audio podcast whose mission is to educate medical providers through clinical cases and topical reviews in neurology, medicine, and the humanities, and episodes originally aired from 2016 to 2021. Originally released December 21, 2017 Nerve conduction testing should not be as puzzling as it's made out to be. This week, we break it down into individual components and use two case examples to explain how you might interpret this commonly implemented electrodiagnostic assessment. Produced by James E Siegler. Music by Coldnoise, Jessie Spillane, Loyalty Freak Music, and Yshwa. Voiceover by Erika Mejia. BrainWaves' podcasts and online content are intended for medical education only and should not be used for routine clinical decision-making. REFERENCES Allen JA.
