Exposition sonore et répercussions auditives au cours de la stimulation magnétique transcrânienne répétitive : données récentes et revue de la littérature

Summary: Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive neurostimulation tool with increasing therapeutic applications in neurology, psychiatry and in the treatment of chronic tinnitus, and with a growing interest in cognitive neuroscience. One of its side effects is the loud click sound generated simultaneously to the magnetic pulse, which depends both on the equipment and rTMS intensity. This impulse sound could transiently modify peripheral hearing mechanisms, and hence hearing thresholds, both in patients and in rTMS practitioners. Furthermore, if no precautions are taken, especially in subjects with several risks factors for hearing loss, it is possible that the repetition of exposure could lead to more definitive changes in hearing thresholds. These issues are often neglected, although they could have specific relevance in rTMS treatment for tinnitus or in auditory cognitive neuroscience. This review specifically deals with noise exposure during rTMS and its potential consequences on the auditory system. It provides several practical solutions to help minimize exposure.
