12/15/2024- In this AANEM podcast, Carrie Ford, a CNCT and R.NCS.T. from the University of Utah's Jack Petajan EMG Lab, interviews Dr. Kyle Mahoney, an associate professor at the University of Utah, who provides a comprehensive explanation of neuromuscular junction transmission and the critical concept of the "safety factor." He breaks down complex neurophysiological concepts using accessible analogies, explaining how the safety factor serves as a built-in buffer that ensures reliable nerve-to-muscle signal transmission. The discussion covers normal neuromuscular junction function, the impact of various pathological conditions such as Lambert-Eaton Myasthenic Syndrome, myasthenia gravis, and ALS on neuromuscular transmission, and the clinical significance of repetitive nerve stimulation testing. Dr. Mahoney's clear explanations make these technically challenging concepts more approachable for healthcare professionals, particularly EMG technicians who may be less familiar with the underlying mechanisms of neuromuscular transmission. 24 min.
Join us in this episode as Devon Rubin, MD, challenges Professor Erik Stalberg with an unknown case and discusses various EMG approaches to a patient with suspected neuromuscular junction disease. Watch Professor Stalberg grade Dr. Rubin’s single fiber pairs and hearing about single fiber EMG on dogs will surely make you smile!
