Summary
Parkinson s disease (PD) is a progressively disabling movement disorder afflicting many elderly Australians. It is caused by the degeneration of specific nerve cells in the brain that produce certain chemicals and patients suffer from an inability to move fluently (or ultimately at all). At present we do not know what triggers this neurodegeneration, but it is believed that complex interactions between inherited (genetic) and environmental factors contribute significantly to the phenomenon. This ....Parkinson s disease (PD) is a progressively disabling movement disorder afflicting many elderly Australians. It is caused by the degeneration of specific nerve cells in the brain that produce certain chemicals and patients suffer from an inability to move fluently (or ultimately at all). At present we do not know what triggers this neurodegeneration, but it is believed that complex interactions between inherited (genetic) and environmental factors contribute significantly to the phenomenon. This project aims to learn more about these complex interactions and their association with PD. People with PD and unaffected individuals will be recruited from throughout Australia and we will look for specific combinations of genetic, environmental and lifestyle factors that either increase or decrease an individual's risk for PD. This research will identify the most common dominant genetic and environmental influences for PD in Australia, enabling scientists to focus on the most relevant biological pathways to target therapeutically.Read moreRead less

Summary
While it is well known that autism and Asperger's disorder are associated with social, communicative, and behavioural symptoms, it is less well known that affected individuals also have considerable movement and coordination difficulties. For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running. These skills are very important for success at school; for example, if children are unable to participate in school sports they often feel isol ....While it is well known that autism and Asperger's disorder are associated with social, communicative, and behavioural symptoms, it is less well known that affected individuals also have considerable movement and coordination difficulties. For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running. These skills are very important for success at school; for example, if children are unable to participate in school sports they often feel isolated and rejected from the peer group. Also, hand writing problems have a significant impact on children's academic performance. Our previous research has suggested that there may be particular patterns of motor problems that characterise individuals with autism and Asperger's disorder. Our proposed research aims to use the kinds of 3D motion analysis technology used in the movie industry to capture exactly how people affected by these conditions move and respond to the environment. This study will enable us to highlight particular parts of the brain-motor circuitry that are affected by these disorders and will also enable us to more clearly distinguish how autism is different from Asperger's disorder. Ultimately, it is hoped that our motor investigations will lead to improved assessment and interventions for these disorders.Read moreRead less

Summary
Autism is a developmental disorder characterised by a triad of deficits: delayed and atypical language development, impaired development of social skills, and ritualistic and stereotypic behaviour. Although not part of the standard diagnosis, movement disorders and gait abnormalities have been clinically observed in autism similar to those seen in Parkinson's disease. In addition, individuals with Asperger's disorder may appear more clumsy, have a stiff or awkward way of walking, and exhibit poo ....Autism is a developmental disorder characterised by a triad of deficits: delayed and atypical language development, impaired development of social skills, and ritualistic and stereotypic behaviour. Although not part of the standard diagnosis, movement disorders and gait abnormalities have been clinically observed in autism similar to those seen in Parkinson's disease. In addition, individuals with Asperger's disorder may appear more clumsy, have a stiff or awkward way of walking, and exhibit poor coordination in posture and gesture. It has been suggested that there is disruption within the basal-ganglia-thalamocortical circuitry (the region connecting the frontal and sub-cortical structures), which may cause the motor dysfunction seen in autism and Asperger's disorder. Few studies have attempted to isolate particular stages of motor functioning which may account for the coordination and motor delay observed clinically in autism and Asperger's disorder. A recent study of ours found evidence to suggest that motor planning deficiencies may account for the 'clumsy' movement patterns frequently reported in the autism - Asperger's disorder literature. Therefore, the aim of this research is to provide a comprehensive neurobehavioural and neurophysiological analysis of motor functioning in young people with autism and Asperger's disorder to further examine the exact stages of motor processing which are deficient in these disorder groups. Recent retrospective studies have shown that even as infants children with autism exhibit clear features of motor disturbance, which, if detected and clearly defined, could advance early diagnosis. In addition to advancing the clinical definition of autism and Asperger's disorder, a careful examination of motor disturbance may also illuminate the neurobiological underpinnings of these disorders.Read moreRead less
Ocular Motility In Autism And Asperger S Disorder: Dissociation Of Motor Deficits.

Summary
We will use ocular motor technology to investigate motor dysfunction in autism and Asperger's disorder, to advance our understanding of the neurobiological bases of these disorders. This will help clarify whether neural networks are differentially disrupted in these disorders, as our previous clinical research suggests. This dissociation and the subsequent development of an ocular motor clincal screen may improve diagnosis, and potentially treatment, of these devastating conditions.
Prevalence report by the Australian Advisory Board on Autism Spectrum Disorders (ASD) estimated that 1 child in every 160 children in the 6-12 year-old age group is affected by ASD. There is no cure for ASD and the causes are not understood. We propose that sex hormones may play a role in the development of these disorders. We will test this hypothesis using knockout and transgenic mouse models which have social interaction deficits and brain structure reminiscent of these disorders.
Evaluating the impact of obesity on knee load over time in those who have undergone optimal surgical re-alignment after total knee replacement . This project investigates the impact of obesity on alignment and knee load over time in those who have undergone total knee replacement. This information is critical for understanding whether obesity results in increasing knee load after surgery which can lead to more rapid wearing of the knee surfaces and an earlier need for revision surgery.
The implications of resistance training for the control of movement. Resistance training (or weight lifting) is an essential element of comprehensive rehabilitation programs in a wide range of clinical settings. However, because we know little about how the organization of the nervous system is affected by training with high loads, the consequences of resistance training for our ability to control functional movements are unclear. The ultimate goal of this research is to generate basic knowledge ....The implications of resistance training for the control of movement. Resistance training (or weight lifting) is an essential element of comprehensive rehabilitation programs in a wide range of clinical settings. However, because we know little about how the organization of the nervous system is affected by training with high loads, the consequences of resistance training for our ability to control functional movements are unclear. The ultimate goal of this research is to generate basic knowledge about the impact of resistance training on nervous system function. The research will lead to the design of injury prevention and rehabilitation programs that are maximally effective, and provide a genuine benefit to the community.Read moreRead less

Summary
Since the discovery of the Huntington's disease (HD) gene mutation there has been much controversy in the literature relating to whether there are any preclinical deficits in individuals who are gene positive for HD but who have not yet been clinically diagnosed with the disease.

Our aim is to examine, over a three year period, the cognitive, attentional and motor performance of presymptomatic gene-positive, and negative, individuals on a wide variety of computerized experimental procedures, which we have previously shown to be sensitive to deficits in individuals who have already been diagnosed with HD. If progressive behavioural changes in gene-positive individuals can be reliably documented to occur before the clinical symptoms of HD are evident, this would be of profound significance as it would allow a set of criteria to be established to assist in early detection of clinical onset of symptoms, and possibly permit use of newly-emerging therapies.Read moreRead less
