Because humans consciously keep our heads straight while the vestibulospinal reflex
is active, the muscles go into spasm when they attempt to move the neck.
([section]) Vestibulospinal reflex
; pathologic postural sway.
The vestibulospinal reflex initiates the compensatory body movements necessary to maintain posture and to stabilize the head over the trunk.
Changes in the vestibulospinal reflex are difficult to assess because of functional overlap with sensory and motor functions.
Information from the vestibular system and their central pathways is integrated with visual and proprioceptive afferent nerve potentials to obtain gaze stabilization and postural stability via the vestibulo-ocular and vestibulospinal reflexes
Most rehabilitation programs involve a graded series of eye, head and body movement exercises designed to train the patient's nervous system to compensate for the impairment of normal vestibulo-ocular and vestibulospinal reflexes
