The vestibular system includes the parts of the inner ear and brain that help control balance and eye movements. Our visual system works with our vestibular system to keep objects from blurring when our head moves and to keep us aware of our position when we walk or when we ride in a vehicle. The system may be damaged by disease, aging, or injury.
The vestibulo-ocular reflex (VOR) is important for maintaining visual stability during tasks that move the head rapidly and unpredictably, for example, as occurs during running or when driving on a bumpy road. The vestibular organs, one in each inner ear, sense rotational and linear head motion and move the eyes to compensate for passive head movements. The vestibular organ can be damaged by disease, degenerative conditions and by chemical or surgical interventions. When both vestibular organs are damaged it can be severely debilitating. The research in this laboratory has two closely related goals: 1) to understand the signal processing mechanisms that control the VOR by analysing vestibular-evoked eye movements and single-unit (vestibular nerve) recordings; and 2) to apply this knowledge of basic vestibular physiology to the diagnosis and treatment of balance disorders in humans.
Despite effective treatments being available, up to 40% of older people with reported dizziness remain undiagnosed and untreated. A multidisciplinary assessment battery, with new validated assessments of vestibular impairments is required for diagnosing and treating older people with dizziness. This project conducted a randomised-control trial of a multifaceted dizziness intervention based on a multidisciplinary assessment, and developed a multiple profile assessment of dizziness for use in Specialist Clinics.
I invite you to read our latest publication – NeuRA’s 2016 Profile – where we have divided our research into five sections: childhood, adolescence, adulthood, midlife and older age to reflect the considerable range and diversity of our research. Significant achievements in human progress have come from harnessing the power of medical research, technology and innovation to accelerate health interventions. […]
