Abstract
Electrophysiological studies record the electrical activity of muscles or neural structures as a function of time. This activity can be spontaneous as in electroencephalography and electromyography, or it may be the consequence of stimulation as in nerve conduction velocity measurements and evoked potential studies. Electrophysiological studies evaluate neural tissue, the neuromuscular junction and muscle function. They are minimally invasive but require sedation and frequently anaesthesia. The cost of the equipment and the experience needed for conducting these studies limit their use to academic and referral clinics. this chapter looks at types of recorded potential, evaluation of the peripheral motor system, evaluation of the peripheral sensory system, evaluation of central afferent pathways, special senses, electroencephalography.
