Quantitative Electromyography

Show Summary Details

Preview

The quantitative evaluation of individual MUPs, decomposition of the interference pattern, IPA of turns and amplitude, and frequency and power-spectrum analyses of the interference pattern are all useful techniques. They evaluate different features of the voluntary activity of skeletal muscle, with results probably reflecting different properties of the function and dysfunction of motor units. One method is not necessarily superior to the others. It is likely that the more methods used, the closer the examiner will come to understanding the functional structure of the muscle being studied and whether or not a neuromuscular disorder is present.
