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.
3/18/2024 -This podcast is a discussion of three challenging electrodiagnostic cases. Teresa Spiegelberg, CNCT interviews three neuromuscular and electrodiagnostic experts: Dr. Ann Little, MD, Dr. Gary Gallagher, MD, and Dr. James Leonard, Jr. MD. The first case explores the challenges of routine electrodiagnostic testing in someone with a chronic, underlying brachial plexopathy. The second case discusses the expected electrophysiological changes in a patient with a presynaptic neuromuscular junction disorder. In the third case, electrophysiological features of a patient with Hirayama's Disease (i.e. monomelic amyotrophy) are discussed. 25 min.
