DESCRIERE

Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by nerves and muscles. Interpreting EMG is a mandatory skill for neurologists and rehabilitation specialists. This textbook provides the reader with a detailed discussion of the concepts and principles underlying electrodiagnostic medicine. It is written for an audience without pre-existing knowledge in this discipline, including beginner technicians and physicians in training. It is an ideal review for seasoned practitioners and those preparing for board examinations. It begins with a review of the foundational sciences and works through the field in twenty chapters, including a large number of case studies demonstrating correct application and interpretation. Appendices of information frequently required in the EMG laboratory, such as Nerve Conduction Study techniques and their age-related normal values, anatomic regions assessed by each NCS and needle EMG studies, safety issues, and other important topics, are also included.

Provides a large number of cases, each of which is discussed as the study unfolds, allowing the reader to 'think through' the findings with the author
Contains reference information frequently sought in the day-to-day practice of electromyography (EMG)
Includes essential EMG skills exercises such as interpreting waveforms, calculating the degree of the various pathophysiologies producing the lesion, and calculating motor unit action potential (MUAP) parameters, recruitment ratios, and firing rates
