VESTIBULAR EVOKED MYOGENIC POTENTIALS IN ALTERED GRAVITY

Recently, new clinical testing of saccular and utricular function have been developed and validated, the so-called vestibular-evoked myogenic potentials - VEMP (Brantberg et al. 2009, Cornell et al. 2009, Curthoys 2010, Manzari et al. 2012). Among them, the cervical VEMP (cVEMP) are short-latency electromyographic (EMG) modulations of the contracted sternocleidomastoid muscles in responses to vibration applied on the forehead. The clinical literature suggests that cVEMP are alm...

OVEMP in Myasthenia

Myasthenia gravis is an autoimmune disorder of neuromuscular transmission, characterized by fluctuating muscle weakness and fatigability. In isolated ocular myasthenia, when only the extraocular muscles are involved, most common ancillary tests, such as acetylcholine receptor autoantibodies and repetitive nerve stimulation, are often negative. A simple, quick and non-invasive test for ocular myasthenia based on ocular vestibular evoked myogenic potentials (oVEMP) was recently ...
