Vestibular rehabilitation (VR), also known as vestibular rehabilitation therapy (VRT), is a specialized form of physical therapy used to treat vestibular disorders or symptoms, characterized by dizziness, vertigo, imbalance, posture, and vision. These primary symptoms can result in secondary symptoms such as nausea, fatigue, and difficulty ...

To compensate for this, the VOR moves the eyes right-to-left slowly, until it reaches the limit, and the eyes then pull to the right rapidly (nystagmus). This is the positional alcohol nystagmus, phase I (PAN I). The unusual vestibular stimulation also caused motion sickness symptoms: illusions of bodily rotations, dizziness, and nausea.
The exercise is a form of habituation exercise, designed to allow the person to become accustomed to the position that causes the vertigo symptoms. The Brandt–Daroff exercises are performed in a similar fashion to the Semont maneuver; however, as the person rolls onto the unaffected side, the head is rotated toward the affected side.
This "Figure Eight" exercise works the muscles differently by moving the head and keeping the eyes in place. Stare at a fixed object straight ahead. Close one eye.
vestibular function (the ability to know one's head position in space) vision (which can be used to monitor and adjust for changes in body position). A patient who has a problem with proprioception can still maintain balance by using vestibular function and vision. In the Romberg test, the standing patient is asked to close their eyes.
The vestibular-ocular reflex (VOR) is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement, thus preserving the image on the center of the visual field. For example, when the head moves to the right, the eyes move to the left, and vice versa.
Gaze stability exercises – moving the head from side to side while fixated on a stationary object (aimed at assisting the eye to fixate during head rotation without the input from the lost canal vestibulo-ocular reflex). An advanced progression of this exercise would be walking in a straight line while looking side to side by turning the head.
