Increased susceptibility to falling is one of the most serious problems associated with ageing. Approximately one third of people aged 65 years and over living in the community fall at least once a year, with up to one fifth of these people suffering multiple falls.
Our balance and falls research focuses on vision, leg sensation, lower limb strength, reaction time and postural stability to understand additional risk factors. We also look at footwear-surface interactions, confusion and dementia, eyewear, hospital settings, fear and risk-taking behaviour.
Multiple factors play a role in falls and related injuries, however poor balance is the cause of the majority of falls in older adults.
Human balance depends on the interaction of our senses of sight, touch, etc. and our ability to control the movement of our bodies. These abilities decline significantly as we age, which can lead to falls, even when there are no identifiable neurological or musculoskeletal problems.
Falls are the leading cause of injury-related death and hospitalisation in people aged 65 years and over. At least 40% of people who have been hospitalised because of a fall require subsequent care in a nursing home. A further 10% need ongoing assistance at home from community services.
The rate of falling in older people living in nursing homes is even higher, with various studies reporting fall rates of between 40% and 56% in elderly residents each year.
We will address loss of balance, a pressing health-related issue that affects quality of life in ~5% of the population. Once the balance organ is injured or degrades with age, no treatments restore function. We have identified a nerve-pathway crucial for balance system adjustment & self-repair. The sensitivity of this pathway can be increased with vitamin C. We will determine if vitamin C treatment can improve recovery after balance loss and potentially translate to the clinic.
Falls and functional decline are common in people with dementia. Falls are more likely to result in injury, death and institutionalisation when compared to older people without dementia. There is limited evidence that falls can be prevented in people with dementia. Strategies aimed at maintaining independence and preventing decline and falls are urgently needed. This research will a) further our understanding of fall risk and functional decline and b) explore novel fall and decline prevention programs, including the use of technology in older people with dementia.
There are approximately 17,000 new hip fractures in Australia and 4,000 in New Zealand annually. The cost of the event is enormous, both for the individual and their family, as well as the health care system. There is variation in models of hip fracture care within and between States and Territories (Aus) and District Health Boards (NZ). Much of what happens in the acute and rehabilitation settings impacts directly on the longer term outcomes for the person with the fracture. The ANZHFR allows for timely comparison of meaningful data that can be used by providers of care to understand clinical practice, and trigger a case for change in places where improvement can be made.
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 will therefore aim to conduct a randomised-control trial of a multifaceted dizziness intervention based on a multidisciplinary assessment, and develop a multiple profile assessment of dizziness for use in Specialist Clinics.
Neuroscience Research Australia (NeuRA) has developed a series of simple exercises to help older Australian’s maintain their balance and avoid falls this winter, in the comfort of their own home. The campaign, Don’t Hibernate this Winter highlights the increased risk of falls during the winter months as people aged 65 and over tend to stay inside more. According to researchers […]
