Although most commonly comprised of nerve conduction studies (NCS) and electromyography (EMG), it can also include special testing, such as late responses, repetitive stimulation, and single-fiber EMG. Each test sheds light on a different aspect of the peripheral nervous system—from the alpha motor neuron, through the neuromuscular junction, and down to individual muscle fibers. This chapter provides an introduction to EDX testing and reviews nerve electrophysiology and common instrumentation used in EDX studies. Basic descriptions of the different types of EDX studies will also be examined.
