In the clinical setting, therapists come across patients with dizziness, vertigo, or balance deficits who may benefit from vestibular rehabilitation by increasing the utilization of their vestibular system. An electronystagmogram is used to assess occulomotor smooth pursuit and saccadic eye movements. 2 C 2021 Academy of Neurologic Physical Therapy, APTA. EEG - electroencephalogram. The Head Impulse Test is a common bedside test involving turning the patient's head abruptly to observe for whether they are able to maintain a steady gaze on a target during the movement. Various products like balance cushions, Dyna Discs, and floor mats may be used to provide a compliant surface for these exercises.1, Many other vestibular exercises can be used to improve usage of the vestibular system or to work on compensatory strategies to improve balance and safety. [1] VOR VOR Gain Maintained fixation (30 neck flexion, slow) horizontal ______ vertical ______ Head Thrust Test (30 neck flexion, unpredictable head thrust) Head Shake (30 neck flexion, EC with frenzels, 20x; 3 beats of nystagmus) VOR Cancellation (cerebellar inhibition of VOR gain) A typical treatment can include bracing, surgery, spinal injections (for pain management), and physical therapy. Symptoms of concussion may include: If you have suffered a blow to the head, you should see a physician right away; a concussion is nothing to take lightly. The latency of action of the rotational vestibuloocular reflex (r-VOR) is 7-15 milliseconds, which is the time required for the eyes to respond in an equal, but opposite, manner to the motion. VOR testing consisted of oscilla-tions at 0.64 Hz in complete darkness (reexive VOR), with . For the sake of October being National Physical Therapy Month, we will only focus on physical therapy treatments. https://collections.lib.utah.edu/details?id=187678, https://collections.lib.utah.edu/ark:/87278/s63b97tz, Video 6.2 Evaluating the vestibulo-ocular reflex (VOR) with visually enhanced VOR (vVOR) and head impulse test (HIT) from Neuro-Ophthalmology and Neuro-Otology Textbook, Daniel R. Gold, DO, Departments of Neurology, Ophthalmology, Neurosurgery, Otolaryngology - Head & Neck Surgery, Emergency Medicine, and Medicine, The Johns Hopkins School of Medicine; David S. Zee MD, Departments of Neurology, Ophthalmology, Neuroscience, Otolaryngology - Head & Neck Surgery, The Johns Hopkins School of Medicine, : Slow vestibulo-ocular reflex (VOR): Since smooth pursuit and VOR systems are both active, if eye movements are choppy with this maneuver this implies deficits in both pursuit and the vestibular system as in CANVAS; Fast (HIT): Since smooth pursuit fails at high frequencies and high speeds, the VOR is isolated during the HIT even with the lights on; if the eyes initially move with the head during the HIT and then make a "catch-up" saccade back to the examiner's nose (in the opposite direction to the head movement), this is a + HIT toward the side of the rapid head movement and generally indicates a peripheral localization Instructional ocular motor examination procedures.

Another vestibular disorder, benign paroxysmal positional vertigo (BPPV), consists of nearly one-third of all the vestibular diagnoses commonly seen in the clinical setting.4 In patients, vestibular disorders can be very debilitating as they may increase fear of falling, dizziness, vertigo, and/or postural instability, resulting in decreased functional mobility and decreased participation in activities at home and in the community, which leads to further balance problems and deconditioning.1,2. When the head is moved horizontally, the horizontal canals are mainly being evaluated (with minimal contribution from vertical semicircular canals), although the HIT can be performed to evaluate anterior and posterior canals as well, Daniel R. Gold, D.O. The VOMS is a simple test to perform and takes approximately five to 10 minutes to complete. Inversion: 30-35 degrees. Vestibular therapy is a type of physical therapy that is done to help people with vertigo, dizziness, or other related symptoms. Any reproduction of symptoms may indicate central nervous system pathology. In a different study, researchers examined whether postural-control deficits persist beyond the acute state among individuals who have a history of mild traumatic brain injury (mTBI).2Key data for this study was provided by the NeuroCom Sensory Organiztion Test (SOT) postural-assessment batteryan objective assessment protocol associated with the SMART Balance Master, available from Clackamas, Ore-based NeuroCom, a division of Natus. Any abnormality in VOR testing can identify a potential problem in the peripheral vestibular system, which can result in gaze instability when a patients head is in motion.5, Testing for BPPV involves the Dix-Hallpike test for anterior and posterior canal BPPV, and the Roll Test for horizontal canal BPPV. 6 For rotations at higher frequencies and velocities, the VOR gain rises with increases in stimulus velocity (nonlinear). 18 0 obj<> endobj To perform this test, you should be seated in front of your physical therapist.
