- Head rotation is a compensatory strategy used for patients with unilateral pharyngeal and/or laryngeal weakness as well as reduced UES opening1. During head rotation, the endolymph within the semicircular canals has a delay in movement due to inertia, and as a result the endolymph will move the cupula in the opposite direction of head movement. The physical movement of the cupula also pushes the cilia of the hair cells within the cupula2. Head rotations about the horizontal, rotational, and nasal occipital axes produce oculo-vestibular reflex, which shows the slow phase of nystagmus3.Learn more:✕This summary was generated using AI based on multiple online sources.
