The need for computer-aided electromyography.

The limits of quantitative manual electromyography (EMG) are discussed. The role of computers in EMG laboratories is at present to imitate or replace the physician performing the test, extending his memory, to gather valuable information which cannot be obtained in a conventional way or, on the contrary, to delete the redundant information. The difficulties in standardizing the parameters of a single motor unit action potential (MUAP) are mainly related to the complexity of the EMG signal and its variability, particularly in pathological states. A computer-aided quantification of interference pattern is presented. The novel methods of examination applied in computerized EMG laboratories are discussed. The scope and limits of computer-aided EMG should be taken into action potential (MUAP) are mainly related to the complexicity of the EMG be accepted are listed.
