Özet
Objectives: Vestibular evoked myogenic potentials (VEMPs) are biphasic responses recorded from tense anterior neck muscles [sternocleidomastoids (SCM)] with loud sound stimulus. The aim of this study was to record VEMPs from the splenius capitis muscles (SPC). Method: Seventy-four healthy controls were studied. Recordings were performed from the ipsilateral SCM, contralateral and ipsilateral SPC muscles when the subjects were seated and turned their head contralaterally to the ear being tested. The recording sites were named as I, II and III respectively. Results: The responses were recorded in 100% at site I, in 98.6 % at site II, in 97.9 % at site III. The earliest responses were detected at sites II and I, followed by site III. The potential amplitude was determined by the muscle tension. The responses recorded both from flexor and extensor muscles had positive/negative polarity. Conclusions: Extensor neck muscles can also be used for VEMP studies and the responses can be recorded even from mildly contracted muscles which make it easier to study in patients with poor cooperation. Significance: Positive/negative polarity of the muscles recorded from all sites may indicate that sacculo-collic connections are mainly inhibitory in nature.
