Your ears do the remarkable job of allowing you to hear a huge range of sounds, from a whisper to louder sounds and also it helps in balancing our body.
The vestibular system inside the ear detects both circular motion and movement in a straight line. This includes everyday actions such as stopping, starting or turning. The sensory system keeps track of the movement and tension of our muscles and joints. It also monitors the position of our body with respect to the ground. The brain receives signals from all these systems and processes the information gathered to produce a sensation of stability.
The VEMP (vestibular evoked myogenic potential ) is a short-latency electromyographic (EMG) potential , to assess vestibular system and it is evoked in response to high-level acoustic stimuli. The responses are mediated by the vestibular system. It provides ear-specific information about otolith and nerve function.
