inVision Software Package Holding steady — the importance of stable vision Patients with balance problems often complain about problems with their vision, particularly blurring, jumpy vision or dizziness when moving or in busy environments such as the grocery store or shopping mall. Maintaining both visual clarity and balance is necessary to safely perform activities of daily living. This requires a stable gaze and a stable body while moving about, particularly when head movements are required. The complex process of assessing and rehabilitating the function of the Vestibulo-Ocular Reflex (VOR) can now be easily, reliably and objectively performed in clinic with NeuroCom’s inVision package. The world's first system for quantifying visual acuity & stable gaze Unique inVision protocols document the presence of VOR dysfunction Practical Reliable objective data help clinicians develop targeted treatment and monitor patient progress Specific Used by leading researchers in balance & mobility programs worldwide VOR Assessment Rigorous stimulus control, reliable DVA testing, and a new GST protocol come together to identify and quantify VOR performance deficits. NEW! VOR Rehabilitation Training Exercises Track direction of head movement and duration of training performance, capture accuracy of visual acuity at the point of retinal slip, and set parameters for target head movement velocity specific to the patient's GST results and customize to adjust at the clinician’s discretion. www.natus

Evaluation of the vestibular system is an important part of the examination of balance problems, and it can be the most challenging. The Vestibulo-Ocular Reflex (VOR) is responsible for stabilizing the visual field during high velocity head movements. The challenge is to first isolate VOR performance and then to understand how it is contributing to the balance problem. Identifying problems within the gaze stabilization system and quantifying their effect upon function with the Dynamic Visual Acuity (DVA) and the Gaze Stabilization Test (GST) protocols can provide the key to resolving these...

Vestibular Rehabilitation Training of the VOR — NOW with Computerized Exercises* The patient is tested using the inVision DVA and GST protocols. The DVA and GST scores are used to determine the starting point for training. During VOR rehabilitation training exercises, the center target changes direction to record visual accuracy while the head moves at the target velocity. In training, the patient must move their head continuously for up to 2 minutes and call out the correct optotype direction. The operator can modify the training parameters by selecting the optotype size, target velocity...

inVision Software Vestibular Training Exercises with Postural Tasks Additional clinically significant information can be measured when performing VOR rehabilitation training while maintaining balance on a NeuroCom static or dynamic Force Plate. On a static balance system, the clinician can incorporate the use of rocker boards or foam on the Force Plate. On a dynamic balance system, the surround and support can be put into dynamic training responsive, variable, or random mode. To add greater complexity, integrating a "busy" background pattern will trigger patient symptoms. Additional...
