Dr. Devon Rubin presents Dr. David Preston with a challenging case of a man with subacute lower extremity weakness. Enjoy the potpourri of information about anticoagulation, A waves, F waves, demyelination, ultrasound, Siri, and so much more!
Have you ever encountered a patient with progressive patchy weakness in various muscles throughout the body? Have you ever performed an EMG in which the findings don’t always fit perfectly into what you were expecting? Have you ever wondered whether you even need to perform an EMG in a patient with weakness? Have you ever wondered how much fun it would be to listen to a new episode of Lessons From the Lab? Well, you have come to the right place to find some answers to these questions! Join Drs. Rubin and Narayanaswami as they ponder and discuss many clinical, electrodiagnostic, and practical approaches to an interesting patient with progressive weakness.
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.
