E-book: Single Fiber EMG-PDF

Pdf Summary

<em>Single Fiber Electromyography: Studies in Healthy and Diseased Muscle</em> (3rd edition, 2010) is a comprehensive reference on SFEMG, written by Erik Stålberg, Jože Trontelj, and Donald Sanders. The book explains how single-fiber electromyography works, how it differs from conventional EMG, and why it is a complementary tool rather than a miniature version of standard EMG.

It covers the basic physiology and morphology of the motor unit, the nature of single muscle fiber action potentials, and the technical principles behind selective recording. Major topics include electrodes, amplifiers, display and storage systems, voluntary and electrically stimulated recordings, and methods for measuring jitter, blocking, fiber density, propagation velocity, and motor unit territory.

A large portion of the book is devoted to clinical applications. SFEMG is presented as especially valuable in disorders of neuromuscular transmission such as myasthenia gravis, Lambert-Eaton syndrome, botulism, congenital myasthenic syndromes, and overlap syndromes. It also discusses neurogenic disorders, peripheral neuropathies, reinnervation, primary muscle diseases, myotonic and channel disorders, and unusual conditions such as hemiplegia, scoliosis, and fasciculations.

The book also explores related techniques, including scanning EMG, macro EMG, multielectrode mapping, reflex studies, and the use of SFEMG in animals. Special attention is given to technical pitfalls, normal reference values, and the interpretation of abnormal findings. The appendix provides normative data, electrode maintenance instructions, and sources of error.

Overall, the volume serves as both a practical guide and an historical/scientific overview of SFEMG, aimed at beginners and experienced electromyographers alike.
