Summary
With an increased longevity of the population, age-related health problems, such as falls, are a significant socioeconomic issue to be addressed. Many sensory systems (e.g. vision, hearing, balance) are known to gradually become disrupted as a consequence of ageing. This project will investigate the consequences of declining sensory systems for balance control in older adults and to develop technology to prevents falls in them.

Summary
The increased occurrence of falls with advancing age (33-50% of people aged >65 years) is a significant cause of mortality (1014 deaths in 1998), morbidity, and disability, affecting not only the individuals concerned, but the health care system (45,069 fall related hospitalizations in 1998 in Australia) and the broader community (National falls Prevention Initiative, 2004). Although there are a number of falls risk tests, most rely on determination of body sway while standing when the body i ....The increased occurrence of falls with advancing age (33-50% of people aged >65 years) is a significant cause of mortality (1014 deaths in 1998), morbidity, and disability, affecting not only the individuals concerned, but the health care system (45,069 fall related hospitalizations in 1998 in Australia) and the broader community (National falls Prevention Initiative, 2004). Although there are a number of falls risk tests, most rely on determination of body sway while standing when the body is static rather than in motion. Given that up to 70% of falls occur during walking and performing transfers, there is a clear need to develop tests of falls risk prediction that incorporate indices of postural stability measured during more dynamic activities. Test development needs to be underpinned by clear evidence of how age-related sensory and motor deficits affect postural stability during walking. The studies outlined in this application will develop and utilise new accelerometer-based technologies to determine the fundamental mechanisms underlying balance control during walking in older people. Specifically, this project will aim to develop a clear understanding of how changes in factors as vision, neuromuscular function (strength, stiffness) and proprioception contribute to the overall decline in stability and balance during walking in older people. Combined with physiological assessment measures developed by the research team, the research will allow the development of a more definitive predictive test of stability and falls risk. This test will be able to be used by health professionals for assessment of older people to determine the most effective therapeutic and-or exercise interventions to target those individuals at risk. This technology will also be adaptable to a biofeedback device to allow individuals to monitor their own stability.Read moreRead less
Bridging The Gap Between Laboratory And Clinic Using Low Cost, High Tech Physical Function Assessment Tools

Summary
Gold-standard testing protocols for assessing standing balance, gait and activities of daily living is often a primary focus for therapeutic interventions. They often incorporate multiple force platforms and 3D motion analysis, which provide valuable information however the time, cost and infrastructure required excludes their use in normal clinical practice. This fellowship examines the potential efficacy of low cost, widely available alternatives such as video gaming devices and smart phones.
Improving Postural Stability In People With Parkinson's Disease Using Textured Insoles.

Summary
Falls are a major health and injury problem for people with Parkinson's disease (PD). In this study we propose to undertake a randomised control trial to determine the efficacy of textured insoles to improve postural stability and reduce falls risk in people with Parkinson’s disease. The success of such an inexpensive device would result in improved health outcomes for individuals and large savings in health care through a reduction in fall-related injuries.

Summary
Benign Positioning Vertigo, the most common and correctable cause of dizziness, is caused by freely floating calcium carbonate crystals in the semicircular canals of the inner ear. Localizing the affected semicircular canal holds the key to effective treatment.A proportion of sufferers will not respond to conventional repositioning treatments due to incorrect diagnoses.

Vestibulo-ocular Reflex Physiology, Pathology And Rehabilitation
Funder
National Health and Medical Research Council
Summary
A sensation of movement from the inner ear is used to stabilise vision during head movements. Without it, every time you walk, run, or drive on a bumpy road, the world would appear to bounce. It can be debilitating when this sense doesn't work due to various diseases. This research examines how this sense works normally and the factors important for self-repair after injury. This work will also develop training exercises using a device for take-home balance rehabilitation.
A Balancing Act: A Three-pronged Approach To Vestibular Assessment

Summary
Vertigo and imbalance are common and disabling symptoms of vestibular (balance) dysfunction. This project will investigate three aspects of vestibular function: by searching for new balance reflexes, revealing the pattern of vestibular deficits in patients with a common form of vertigo caused by migraine, and exploring the impact of vestibular disease on thinking and memory. This research will improve our understanding of the vestibular system and facilitate the diagnosis of episodic vertigo.
This research program is aimed at finding effective prevention strategies for the important issue of falls in older people. It will: a) conduct studies to improve our understanding of fall risk in people with Parkinson’s disease and dementia; b) undertake a study to improve our management of dizziness; c) seek treatments for fear of falling, and d) evaluate home exercise interventions for older people at risk of falls and strength and cued walking training for people with Parkinson’s disease.
Our vestibular system provides us with the important sense of balance. When it fails we suffer debiltating bouts of vertigo and dizziness. A great deal is known about how balance signals are sent from the inner ear to our brains, but virtually nothing is known about the important signals the brain sends to the inner ear. In this study we will use a new perparation develped in our laboratory to examine how these essential brain signals control the function of our balance organs.
