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
Randomised Controlled Trial Of A Tailored Podiatry Intervention To Enhance Mobility And Prevent Falls In Older People

Summary
Foot problems affect 1 in 3 people over the age of 65 years and are associated with reduced walking speed, difficulty performing activities of daily living, impaired balance and increased risk of falls. Although a range of health professionals provide treatment for foot disorders, the most common chronic foot problems in older people (such as corns and calluses, nail disorders and toe deformities) are frequently managed by podiatrists using treatments such as scalpel debridement of lesions, foot ....Foot problems affect 1 in 3 people over the age of 65 years and are associated with reduced walking speed, difficulty performing activities of daily living, impaired balance and increased risk of falls. Although a range of health professionals provide treatment for foot disorders, the most common chronic foot problems in older people (such as corns and calluses, nail disorders and toe deformities) are frequently managed by podiatrists using treatments such as scalpel debridement of lesions, foot orthoses, exercise prescription and footwear modifications. The 1995 National Health Survey reported that persons aged 80 years or over were most likely to have reported visiting a podiatrist in the previous two weeks, followed by those aged 65-79 years. Similarly, the Australian Department of Veterans Affairs, which provides podiatry services to veterans and their dependants, documented 606,706 episodes of podiatry care to 103,540 veterans in 1998-1999, at a cost of $23M. Podiatry therefore plays a substantial role in the maintenance of foot health and mobility in older Australians. Despite the detrimental effects of foot problems and the widespread utilisation of podiatry services by older people, very few studies have been undertaken to ascertain the efficacy of podiatry treatments. Therefore, the aim of this study is to evaluate the efficacy of an individualised podiatry intervention designed to reduce pain, enhance functional mobility and prevent falls in older people. Given the high prevalence of foot-related disability and falls in older people and their associated health care costs, the study findings will be of considerable public health importance. If found to be clinically effective, the intervention could be easily implemented into a range of healthcare settings and adopted in both state and federal falls prevention policies.Read moreRead less
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.
