ABSTRACT

Clinical neurophysiologic tests are many and are grouped together into subcategories according to different criteria. It is practical to distinguish recordings from muscle [electromyography (EMG)] and tests of nerve and nervous pathways function (conduction studies). Typically, the different tests are referred to with disconcerting capital letter abbreviations, and even professionals close to the field have some difficulty in understanding the terminology, complex physiological, and technical background of the methods, and distinguishing the different types of information provided by different tests. This chapter aims at clarifying these issues.
