Learn about computerized dynamic posturography (CDP) from its inventor, Lewis M. Nashner, Sc.D., whose career has brought him from MIT and NASA to developing and researching the application of CDP.
Darren Whelan, BSc (Hons) MSc MRes, has investigated the application of videonystagmography (VNG) in dizzy patients with central nervous system involvement, and how VNG is superior to MRI when looking at eye movements.
The eye movements that are mediated by the inner ear through the vestibular-ocular reflex (VOR) are well-known and used in many clinical tests of vestibular function.
SVV is a test to assess the persons perception of verticality. The patient adjusts a luminous laser presented line to be parallel with true vertical in the absence of any other visual cues. This is done in the Orion Auto-Traverse Chair.
Concussed patients are often referred to physical therapists for diagnosis and treatment. Saccadic systems are great for the objective measurements for diagnosis and treatment of concussed patients.
The suppression head impulse (SHIMP) test is the latest protocol in EyeSeeCam vHIT. The SHIMP test allows you to determine the extent of vestibular function. In cases where the vHIT is difficult to interpret, the SHIMP test can help to show if the vestibular system is functioning. You can also use the SHIMP test to corroborate the level of residual vestibular function, which will help you to set realistic expectations for your patient’s vestibular rehabilitation.
Did you know that 70% of children with sensorineural hearing losses also have a vestibular impairment? Infant hearing screenings allow us to diagnose hearing impairments at a very early age and these infants and small children bring unique testing challenges.
Sharon L. Cushing, MD MSc FRCSC, gives her view on vestibular testing in children and which systems she uses.
