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.
The vestibulo-ocular reflex (VOR) is a reflex that acts to stabilize gaze during head movement, with eye movement due to activation of the vestibular system, it is also known as the cervico-ocular reflex. The reflex acts to stabilize images on the retinas of the eye during head movement. Gaze is held steadily on a location by producing eye ...
Balance skill development in children Balance training using medicine balls. The sense of balance or equilibrioception is the perception of balance and spatial orientation. [1] It helps prevent humans and nonhuman animals from falling over when standing or moving.
Nystagmus in patients indicates dysfunction of the vestibular system, which can lead to dizziness and inability to complete a righting reflex. [1] Proprioceptive ability tests are important in testing for righting reflex function. A therapist may ask a patient whether they know where a certain limb or joint is located without looking at it.
A common example of this reflex is the cat righting reflex, which allows them to orient themselves in order to land on their feet. This reflex is initiated by sensory information from the vestibular, visual, and the somatosensory systems and is therefore not only a vestibulospinal reflex. [8]
The caloric reflex test is designed to test the function of the vestibular system and can determine the cause of vestibular symptoms. The reflex test consists of pouring water into the external auditory canal of a patient and observing nystagmus, or involuntary eye movement. With normal vestibular function, the temperature of the water has an ...
Along with proprioception and vestibular function, the visual system plays an important role in the ability of an individual to control balance and maintain an upright posture. When these three conditions are isolated and balance is tested, it has been found that vision is the most significant contributor to balance, playing a bigger role than ...
Other sensory modalities exist, for example the vestibular sense (balance and the sense of movement) and proprioception (the sense of knowing one's position in space) Along with Time (The sense of knowing where one is in time or activities). It is important that the information of these different sensory modalities must be relatable.
