Electromyogram (EMG) Findings
View through CrossRef
While this chapter, and even this book, are not intended to be a textbook in electrodiagnosis, we have chosen video samples of typical abnormal discharges that often are faced by neuromuscular specialists, such as myopathic units, myotonic discharges, myokymia, fibrillation, and neurogenic firing. Other electromyogram (EMG) clips are embedded in other chapters. Firing frequency of the motor unit potentials can be calculated and it is increased in denervation. Observation for 40–60 seconds may be needed to detect infrequent fasciculations after needle placement. Mixed short and long duration is a features of chronic myopathy and can be confused with chronic denervation.
