The left and right ear are tested in turn by pouring warm or cold water into the ear for 30 seconds while the patient is wearing the VNG goggles. A certain amount of pressure may be felt in the ear canal. The temperature of the water is transferred to the horizontal semicircular canal and warms or cools the inner ear fluid, which briefly changes the fluid density in the vestibular system. This either temporarily activates or inhibits the vestibular system, often resulting in a brief sensation of vertigo. It is recommended to examine both ears with both warm and cold irrigation. Very rarely, ice water is used to find out whether the examined semicircular canal is still functional at all. Performing this test with air instead of water is not reliable and is therefore not recommended.<\/p>                        <\/div>\n\n                    <\/div>\n\n                <\/div><!-- .elementskit-card END -->\n\n                \n                <div class=\"elementskit-card\">\n                    <div class=\"elementskit-card-header\" id=\"primaryHeading-6-4ea9d450\">\n                        <a href=\"#collapse-e9c7ce169e9395137ce1\" class=\"ekit-accordion--toggler elementskit-btn-link collapsed\" data-ekit-toggle=\"collapse\" data-target=\"#Collapse-e9c7ce169e9395137ce1\" aria-expanded=\"false\" aria-controls=\"Collapse-e9c7ce169e9395137ce1\">\n                            \n                            <span class=\"ekit-accordion-title\">4.2 Examination of the vestibulo-ocular reflex<\/span>\n\n                            \n                                <div class=\"ekit_accordion_icon_group\">\n                                    <div class=\"ekit_accordion_normal_icon\">\n                                        <!-- Normal Icon -->\n\t\t\t\t\t\t\t\t\t\t<i class=\"icon icon-plus\"><\/i>                                    <\/div>\n\n                                    <div class=\"ekit_accordion_active_icon\">\n                                        <!-- Active Icon -->\n\t\t\t\t\t\t\t\t\t\t<i class=\"icon icon-minus\"><\/i>                                    <\/div>\n                                <\/div>\n\n                            \n                                                    <\/a>\n                    <\/div>\n\n                    <div id=\"Collapse-e9c7ce169e9395137ce1\" class=\"collapse\" aria-labelledby=\"primaryHeading-6-4ea9d450\" data-parent=\"#accordion-69e9395137ce1\">\n\n                        <div class=\"elementskit-card-body ekit-accordion--content\">\n                            <p>Examination of the vestibulo-ocular reflex (VOR) is crucial for the diagnosis of functional disorders of the vestibular system.

The vestibulo-ocular reflex (VOR) enables us to keep our gaze stable while we move our head. The vKIT tests how the VOR works.<\/p><p>In this test, the patient is asked to focus their eyes on a fixed point while the examiner turns their head quickly. In order to continue to fixate the point, the eyes must move in the opposite direction at the same angular velocity as the head. In patients with a dysfunction, the eyes follow the head movement, which requires a corrective eye jump (\"a saccade\") to bring the gaze back to the target. The head and eye movements are recorded using special glasses.<\/p><p>The vKIT test examines all 6 semicircular canals. In contrast to the caloric test, the vKIT records the reactions to very rapid head movements in the frequency range from 1 to 4 Hz.

The DVA test measures this ability to stabilize the gaze.<\/p><p>Similar to the vKIT, this useful test is used to investigate changes in the VOR. In addition, the DVA test can be used to assess improvements following <a href=\"https:\/\/ivrt.de\/en\/vestibulaere-rehabilitationstherapie-und-gleichgewichtstraining\/\">vestibular rehabilitation<\/a> .<\/p><p>During the test, you are asked to look at the letter \"E\" on a screen and determine its orientation. The letter appears at regular intervals, each time in a different size and orientation. The test is first carried out without head movements, then with. The difference in visual acuity is then compared: The greater the difference between static (without head movement) and dynamic (with head movement) visual acuity, the more severely the VOR is impaired.<\/p><p>There is also a manual version of the DVA test that is performed without special medical technology. This version is used by<a href=\"https:\/\/ivrt.de\/en\/fuer-betroffene\/therapeutensuche\/\"> IVRT\u00ae Dizziness and Vestibular Therapists<\/a> to detect disorders of the VOR.<\/p><p><strong>5.2 Subjective visual vertical and horizontal (SVV and SVH)<\/strong><\/p><p>The subjective visual vertical (SVV) and subjective visual horizontal (SVH) are diagnostic tests that examine the perception of spatial orientation and in particular the parts of the inner ear that are responsible for the perception of gravity (utriculus and sacculus).<\/p><p>In the SVV test, the patient is placed in a dark room and asked to align the projected image of a rotating line so that it is perceived as exactly vertical (SVV) or horizontal (SVH). The dark test environment minimizes visual references, so the perception of the line is highly dependent on the function of the otolith organs (utriculus and sacculus) in the inner ear.<\/p><p>The SVV\/SVH test can be used to detect disturbances in the perception of gravity, which can be caused by dysfunctions of the vestibular system or the vestibular nerve. Deviations in the alignment of the line indicate a malfunction in the macular organs, as is the case in acute <a href=\"https:\/\/ivrt.de\/en\/neuritis-vestibularis\/\">Vestibular neuritis<\/a> or a brain stem\/cerebellar infarction, for example.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-1f01ac4f e-flex e-con-boxed e-con e-parent\" data-id=\"1f01ac4f\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;,&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-706f85 e-con-full e-flex e-con e-child\" data-id=\"706f85\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-125a4cda elementor-widget__width-inherit elementor-invisible elementor-widget elementor-widget-text-editor\" data-id=\"125a4cda\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;fadeInUp&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>What else can I do?<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e2a6e54 elementor-widget__width-initial elementor-invisible elementor-widget elementor-widget-heading\" data-id=\"e2a6e54\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;fadeInUp&quot;,&quot;_animation_delay&quot;:200}\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Where can I find a specialized IVRT\u00ae vertigo and vestibular therapist?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b952bbc elementor-widget elementor-widget-text-editor\" data-id=\"b952bbc\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Vestibular rehabilitation and balance training are most effective when you follow a series of exercises tailored to your specific needs by a therapist.
