Brain networks may reorganize to optimise stroke recovery. However, little is known about brain mechanisms underlying natural and training-induced recovery after stroke, particularly following loss of body sensations.

However, little is known about brain mechanisms underlying natural and training-induced recovery after stroke, particularly following loss of body sensations. Knowledge of the experiences that may facilitate brain reorganisation is a prerequisite for the development and evaluation of optimal stroke rehabilitation strategies. We aim to provide novel information on the potential benefits of specific training in facilitating reorganisation of the brain after stroke. Specifically we will: (i) locate areas of brain activity associated with natural and training-induced recovery of touch sensation following stroke and (ii) investigate the relationship between brain activation, sensory recovery and intervening experience. Site and extent of brain activation associated with recovery of touch sensation will be investigated over time using serial functional magnetic resonance imaging (fMRI), a controlled sensory task and clinical measures of recovery. Thirty stroke patients with impaired touch sensation of the upper limb will be studied at 2-6 weeks and 6 months post-stroke to investigate changes in brain activation associated with natural recovery (Study 1). Ten healthy controls will also be studied over 6 months. Those patients who still have sensory loss at 6 months will then receive specific sensory training or placebo intervention to study the effect of training-induced recovery on brain activity (Study 2). The whole brain will be studied and activation sites will be interpreted relative to individual and standard brain maps. We expect that the findings will advance our knowledge of the relationship between clinical recovery, training and neural plastic changes in the brain. This information will provide direction for the development of scientifically based treatments designed to maximise recovery and help identify patients who are likely to show natural recovery and-or benefit from training.Read moreRead less

Summary
Treatment for Parkinson's disease, including dopamine replacement therapy and deep brain stimulation, fail to produce the same beneficial effects on all movement systems. Whereas limb function is the primary beneficiary of these treatments, other functions such as speech and postural control are less responsive. Critical to the research is the postulate that such differences may have arisen due to the fact that previous studies of dopamine and movement control have investigated distinct motor sy ....Treatment for Parkinson's disease, including dopamine replacement therapy and deep brain stimulation, fail to produce the same beneficial effects on all movement systems. Whereas limb function is the primary beneficiary of these treatments, other functions such as speech and postural control are less responsive. Critical to the research is the postulate that such differences may have arisen due to the fact that previous studies of dopamine and movement control have investigated distinct motor systems via the assessment of distinct movement constructs, making cross system comparisons an impossible task. The proposed research will assess the effect of Parkinson's disease, deep brain stimulation and dopamine on identical muscle functions within the orofacial, trunk and limb muscle systems. To this end, the results generated from this resarch have the potential to reconceptualise working models of brain-muscle relationships. Further the research will provide guidance for future studies that aim to eradicate trade-off effects (e.g. limb function improved but not speech) relating to symptom relief for people with Parkinson's disease.Read moreRead less

Summary
People who suffer brain damage as a result of a stroke, head injury, or a disorder such as Parkinson's disease frequently develop difficulty in either speaking, writing, reading, or understanding the spoken language. As a result, the person's ability to communicate with his or her family and friends, and the community in general is seriously affected.

As a result, the person's ability to communicate with his or her family and friends, and the community in general is seriously affected. Individuals who experience these speech and language disorders are treated by a speech pathologist who focuses on improving the person's ability to communicate. The treatment of these disorders is frequently long-term requiring speech pathology management beyond existing hospital care. For many people with these communication disorders, accessing speech pathology services after their discharge from hospital may be very difficult due to their physical difficulties, the distances they are required to travel, and the limited availability of speech pathologists in their local community. This project aims to overcome these access issues through the development of a telerehabilitation system that will enable speech pathologists to assess people with these speech and language difficulties across the Internet using videoconferencing. It is intended that this research will ultimately enable people with these types of communication difficulties to be assessed and treated within their own home or local community.Read moreRead less

Summary
Traumatic brain injury is the leading cause of disability in young Australians, and is particularly prevalent in young men. The condition disturbs thinking and problem solving. Ultimately, these problems manifest in impaired verbal communication. Communication problems following traumatic brain injury can make critical relationships-such as father, husband, and employee-impossible to sustain. Those affected are socially inappropriate and uncomfortable to be around, which causes a lifetime of los ....Traumatic brain injury is the leading cause of disability in young Australians, and is particularly prevalent in young men. The condition disturbs thinking and problem solving. Ultimately, these problems manifest in impaired verbal communication. Communication problems following traumatic brain injury can make critical relationships-such as father, husband, and employee-impossible to sustain. Those affected are socially inappropriate and uncomfortable to be around, which causes a lifetime of lost friendships, unemployability, and social isolation. Minimisation of these lifelong effects is of the utmost importance to the health of those affected, and is critical to reducing the economic burden of the condition. Two approaches have been shown to improve the communication of those with traumatic brain injury. Training in social skills is helpful, as is training partners to deal with difficult communication behaviours. However, to date, no research has concurrently studied these two approaches to rehabilitation. Consequently, it is unknown whether best results are achieved with either one of the two methods, or both. The present project uses a clinical trials approach in an innovative evaluation of three methods of treating those with traumatic brain injury compared with a control group. The trial involves the conceptual advances of including cost effectiveness of treatment as an outcome measure, and inclusion of advanced methods to measure the intricacies of verbal communication. The multidisciplinary team of Chief Investigators has international track records in the requisite disciplines for the study of traumatic brain injury and its rehabilitation.Read moreRead less

Severe-profound congenital hearing loss engenders significant costs to society. In 2005, specialised education cost -- on average $25,000 per child, loss of productivity cost -- $6.7 billion, and social security benefits were paid to approximately 129,000 individuals who were unemployed due to hearing loss. If bilateral cochlear implantation results in improved language, social development, and academic outcomes, the community benefits arising will be greatly improved quality of life for these individuals and significant savings to society. In partnership with Cochlear Ltd, this study will provide some of the first data worldwide comparing the effects of an additional implant on language, social and educational outcomes.Read moreRead less
An investigation of respiration in stuttering. Australia leads the world in stuttering research, and this project will maintain that profile. The research aims to establish if breathing has a causal role in stuttering. The new knowledge produced will support or weaken current theories of the cause of stuttering and will contribute to understanding the nature of the disorder. In particular, it will be applied to develop more effective and efficient treatments for chronic stuttering.
