For the test, the patient is seated in a chair wearing a pair of goggles that tracks both head and eye movement. The therapist performs quick, small movements of the patient\u2019s head while they focus their eyes on a target.<\/p>\n<p>The test takes approximately 10-15 minutes to perform. We like to discuss the findings of the test with our patients after performing the test.<\/p>\n<p>The physical therapist will determine if it would be a useful test to perform in finding or confirming a diagnosis. It is particularly useful in detecting weakness of the six canals of the vestibular system which can occur on one or both sides of the inner ears diagnosed as vestibular neuritis. Often, the test is performed to rule in or rule out Vestibular Hypofunction which can help guide us in a patient\u2019s treatment plan.<\/p>\n<div style=\"width: 710px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/wwspt.com\/wp\/wp-content\/uploads\/2023\/03\/Dr.-Kelset-Hanlon_performing_the_Video_Head_Impulse_Test_vHIT.png\" alt=\"Dr. Kelsey Hanlon PT, DPT performing the video head impulse test\" width=\"700\" height=\"1088\" \/><p class=\"wp-caption-text\">Dr. Kelsey Hanlon PT, DPT performing the video head impulse test<\/p><\/div>\n<p><strong>Demonstration Video Head Impulse Test (vHIT)<\/strong><\/p>\n<p>(vHIT) tests all six Sensory canals of the Vestibular System.<\/p>\n<div class=\"wwspt-content-box\" style=\"text-align: left;\"><div class=\"su-row\">\n<div class=\"su-column su-column-size-1-2\"><div class=\"su-column-inner su-u-clearfix su-u-trim\">\nVestibular rehab is an exercise approach provided by Dr. Gregory Synnestvedt, a Certified Vestibular Physical Therapist for Inner Earand Balance disorders that affect people daily. Many symptoms can be attributed to the Vestibular System, such as Vertigo or spinning, motion-triggered dizziness, feeling off-balance, and lightheadedness. Watch the video below to see our use of new Vestibular Diagnostic technology, Video Head Impulse Treatment (vHIT), to detect Vestibular impairment.<\/div>\n<div class=\"wwspt-content-box\" style=\"text-align: left;\"><\/div><\/div>\n<div class=\"su-column su-column-size-1-2\"><div class=\"su-column-inner su-u-clearfix su-u-trim\"><\/div>\n<div><\/div>\n<p>&nbsp;<\/p>\n<div class=\"wwspt-content-box\" style=\"text-align: left;\"><center><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/smZrCIZZVYc\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/center><\/div>\n<p>&nbsp;<\/p>\n<div class=\"wwspt-content-box\" style=\"text-align: left;\"><\/div><\/div>\n<\/div><\/div>\n<div><\/div>\n<p><strong>How does the test detect vestibular weakness?<\/strong><\/p>\n<p>Normally, when we turn our head quickly, the canals of the inner ear sense the rapid movement and immediately transmit this signal to the brain. Our eyes then simultaneously move at a speed equal and opposite to the head movement, so that our eyes can stay focused on whatever we are looking at. The vHIT device can detect how well you are able to keep your eyes focused on the target while your head is being moved quickly by comparing the speed of the eyes to the speed of the head. If your eye lags behind while your head is moved, this suggests decreased input from the canal being tested. Often, if there is a deficit in canal function, the eyes must make small corrections called \u201ccorrective saccades\u201d which can be seen in the graphic read-out from the vHIT. Changes in the timing of these saccades after therapy shows recovery of the vestibular system<\/p>\n<div style=\"width: 710px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/wwspt.com\/wp\/wp-content\/uploads\/2023\/03\/Testing-a-patient-with-BPPV-on-a-large-low-table-tilted-up-to-accommodate-a-patient-with-neck-and-back-pain-using-wireless-Synapses-infrared-video-goggles.png\" alt=\"Testing a patient with BPPV on a large, low table tilted up to accommodate a patient with neck and back pain, using wireless Synapses infrared video goggles\" width=\"700\" height=\"987\" \/><p class=\"wp-caption-text\">Testing a patient with BPPV on a large, low table tilted up to accommodate a patient with neck and back pain, using wireless Synapses infrared video goggles<\/p><\/div>\n<p>&nbsp;<\/p>\n<p>WWS Physical Therapy and Vestibular Rehabilitation<br \/>\n1456 Ferry Road, Suite 601<br \/>\nDoylestown, PA 18901, USA<br \/>\nTel: 215.489.3234\u00a0<strong>|<\/strong>\u00a0Fax: 215.489.0131<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Video Head Impulse Test for Vestibular Function\u00a0 \u00a0The video head impulse test, also called \u201cvHIT,\u201d can help accurately assess the functioning of your vestibular system \u2013 the part of your inner ear that detects head movements.
