Abstract

Introduction<BR>For transcranial magnetic stimulation of the facial nerve, a magnetic coil is fixed to the temporal region over the nerve. It has been reported that the facial nerve can be stimulated at the distal part of the auditory canal, and it is expected that the peripheral vestibular organs are included in the time-varying magnetic field. We examined the influence of magnetic stimulation on the peripheral vestibular organs using a stabilometer.<BR>Methods<BR>Experiments were carried out on 10 healthy adults. Magnetic stimulation was administered to the temporal region including the peripheral vestibular organs and stabilometry was performed before and after stimulation. We used a G5500 system stabilometer (Anima Co.) with a sampling time of 20 msec. and recorded body sway for 60 sec. A Mag lite (Dantec Co.) was used for magnetic stimulation and a Synax ER 1100 (NEC-Sanei Co.) was used as the trigger. The stimulus was set at 4 Hz and stimulation was done 60 times. The output was set at about 40% of 1.9 Tesla (maximum output).<BR>Results<BR>We analyzed the body sway length, 8-directional body sway velocities, and the power spectrum of the lateral body sway velocity. The total length of body sway and the velocity of lateral sway increased significantly after magnetic stimulation.
