Resumen

ALVAREZ FIALLO, Roger et al. Single fiber electromyographic study in neuromuscular diseases. Rev Cub Med Mil [online]. 2005, vol.34, n.2. ISSN 0138-6557.

The single fiber electromyography was implemented in the health care practice. The single fiber electromyographic study of 191 patients with neuromuscular diseases was carried out. It was obtained a positivity of 15,2 % in the studies conducted in the group of C6 radiculopathies; 33,3 % in the brachial plexus injuries; 44,1 % in the amyotrophic lateral sclerosis; and 21,9 % in the myopathies. Its sensitivity was stressed in the group of patients with myasthenia gravis that reached 70 %. To conclude, it was ratified the high sensitivity of the method of single fibre electromyography in the diagnosis of myasthenia gravis, and it was underlined its moderate or low positivity in the rest of the studied diseases.

Palabras clave : Electromyography; single fibre electromyography; neuromuscular diseases; sensitivity; electromyographic diagnosis.
