Abstract
This chapter describes magnetic stimulation, which means the electrical stimulation from magnetic field-induced eddy-currents rather than from direct stimulation by the magnetic field. Current induced from magnetic stimulation can excite not only the motor cortex but also the motor roots in the region of the intervertebral foramina, as well as peripheral nerves and plexuses. With the use of a specially constructed coil, magnetic stimulation may activate the pyramidal decussations but not the spinal cord. This technique has limited application in the assessment of the peripheral nerve for two reasons: (1) the inability to pinpoint the exact activation site; and (2) difficulty to stimulate selectively a specific nerve under consideration. Advances in coil design may further improve the technical precision and clinical utility of transcranial magnetic stimulation in the study and diagnosis of the peripheral nerve diseases.
