Summary
Stroke is the leading cause of long-term disability in adults in Australia, accounting for approximately 25% of all disability. A common motor disability resulting from stroke is hemiparesis, weakness or paralysis on one side of the body. This disability severely impairs an individual's capacity to perform activities of daily living, making them dependent on relatives and health professionals for daily care. By developing effective interventions to treat stroke-induced hemiparesis both the disab ....Stroke is the leading cause of long-term disability in adults in Australia, accounting for approximately 25% of all disability. A common motor disability resulting from stroke is hemiparesis, weakness or paralysis on one side of the body. This disability severely impairs an individual's capacity to perform activities of daily living, making them dependent on relatives and health professionals for daily care. By developing effective interventions to treat stroke-induced hemiparesis both the disability caused by stroke and the associated personal and financial costs will be lessened. A number of interventions focusing on the affected side (unilateral), including active movements and muscle stimulation are being investigated as possible treatments for stroke-induced hemiparesis. Recent evidence suggests that involving the unaffected side simultaneously (bilateral therapies) could be effective, and may provide addtional benefits over unilateral therapies. The aim of this research is to thoroughly examine the effectiveness of bilateral therapies by incorporating them into established interventions. The findings from these studies will aid in the development and refinement of movement therapies aimed at promoting recovery from stroke-induced hemiparesis.Read moreRead less
Outcome Of High Tibial Osteotomy For Medial Compartment Osteoarthritis Of The Knee: A Long-term Follow-up

Funding Amount

Summary
In the young, active person, medial compartment osteoarthritis of the knee is a difficult problem to manage. Surgical options, such as total knee replacement, are often unsuccessful, due to functional restrictions and the need for revision surgery. An alternative is to extend the life of the arthritic knee by moving the primary weight-bearing surface to the other compartment (laterally), in an operation known as a high tibial osteotomy. This research looks at the outcome of this procedure.
The FREEDOM Study: A RCT Of Sunlight And Calcium To Reduce Vitamin D Deficiency In Older People In Residential Care

Summary
The proposed study emanates from a large ongoing epidemiological study on falls and fractures in the elderly (the FREE study). Falls and fractures are major problems in the elderly. This is the genesis for the FREEDOM (Falls Risk Epidemiology: Effect of vitamin D on skeletal Outcomes and other Measures) intervention study.

Falls and fractures are major problems in the elderly. This is the genesis for the FREEDOM (Falls Risk Epidemiology: Effect of vitamin D on skeletal Outcomes and other Measures) intervention study. The FREEDOM study will evaluate the effect of a public health strategy to reduce falls and fractures in older people living in residential care (namely appropriate sun light exposure and calcium supplementation) in a randomised trial. The primary endpoints of this study will be reduction in falls and change in vitamin D levels. Other endpoints will be change in motor function, mood, bone turnover and fracture incidence. The proposed public health strategy to be examined is readily transferable to routine practice and would have very good feasibility for easy implementation and are generally applicable to the residential care setting, where the study will be conducted. Moreover the proposed approach would be low in cost and does not depend on other health system input. Potentially large numbers of people would benefit from the better understanding of simple methods of securing improved vitamin D status.Read moreRead less
Sensorimotor Control Of Foot Function: Adapting The Mechanical Function Of The Foot To Optimise Balance And Gait Performance

Funding Amount
$314,644.00
Summary
Walking and running places immense load on our feet, with 20% of adults suffering from foot pain. Recent research has highlighted the important role of the muscles within the foot in facilitating our ability to withstand excessive load and maintain balance. But it remains unknown how the nervous system controls this function. This research will explore how the brain and spinal cord control these muscles, providing a comprehensive understanding of the role of the foot in balance and gait.

Summary
Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development. The first objective of this study is to use 3D-motion analysis to ‘probe’ the underlying brain dysfunction which characterises ADHD-CT. The second objective of this study is to improve our understanding of the link between movement problems, and (a) injury proneness, and (b) social-communicative problems, in children with AD ....Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development.

Mechanisms Of Cortical Plasticity And Facilitation Of Functional Recovery Following Stroke

Summary
Specific regions of the human brain have been shown to reorganise following damage to the brain or peripheral nerves. This reorganisation is seen in both young and older subjects and is thought to be useful in helping to restore function. For example, following a stroke a patient may, initially, be unable to move one arm. However, in the following weeks and months some function may return. A number of mechanisms may be responsible for this improvement.

This reorganisation is seen in both young and older subjects and is thought to be useful in helping to restore function. For example, following a stroke a patient may, initially, be unable to move one arm. However, in the following weeks and months some function may return. A number of mechanisms may be responsible for this improvement. However, it is likely that at least some of the improvement is due to reorganisation within the sensorimotor cortex. Following the stroke the control of the arm may be taken over by adjacent undamaged regions of the brain. This reorganisation allows impressive functional recoveries to occur. We have preliminary evidence to support the idea that patterns of activity generated in peripheral nerves (afferent input) following stroke may be crucial for the development of the organisational changes seen within the brain. We have shown that by applying specific patterns of sensory input we are able to produce organisational changes within the motor cortex of control subjects. Also, we have been able to induce similar changes in stroke patients. These changes have been accompanied by improvements in motor control. These novel and exciting findings support our hypothesis that by applying certain patterns of afferent input to patients following stroke we will be able to facilitate functional recovery by maximising reoganisation within the cortex. In the present project we will establish the organisation patterns in the brain of stroke patients and contrast the findings with control subjects. Secondly we will investigate the potential for facilitating recovery of stroke patients by the application of specific patterns of afferent input. These novel experiments may lead to important therapeutic developments that will benefit the large population of patients suffering strokes.Read moreRead less

Understanding The Human Hand In Grasping And How This Changes After Stroke

Funding Amount

Summary
The hand allows remarkable feats of dexterity. But, paralysis of the hand severely limits daily activities and is common after stroke. We will determine key mechanisms that control the hand at the level of the brain and spinal cord. We will assess some limits that develop in the muscle itself. Stroke patients will be tested so that we can better understand the brain�s control of the hand and use this to enhance recovery of hand performance in those with impaired function.
