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
Accurate Differentiation Of Acquired Speech And Language Disorders For Positive Rehabilitation Outcomes

$398,840.00
Summary
Loss of speech due to acquired brain injury causes long-term disability, increased risk for depression, and substantial caregiver burden. Speech disorders can affect linguistic processes or control of speech movements. The current gold standard for diagnosis of speech movement disorders is expert judgment of speech characteristics. We propose to test a novel diagnostic tool that has potential to drive a reframing of rehabilitation strategies to improve outcomes and quality of life.
Optimising Speech Assessment And Treatment In Frontotemporal Dementia

Summary
Frontotemporal dementia has a devastating impact on our ability to speak and understand others. This proposal aims to improve our understanding of how to best assess, diagnose and treat these debilitating impairments. By bringing together an international consortium of clinics, these findings will lead to significant advances in our understanding of disease progression and patient care.

Summary
Childhood speech and language disorders are common and may have negative long term outcomes. We have a limited understanding of what causes these disorders, which impacts our ability to manage and treat those affected. This project will utilise large families to investigate causes and clinical features of speech and language disorders. This is an exciting and relatively under-research area, and has the potential to lead to improved outcomes for children affected with speech and language disorder ....Childhood speech and language disorders are common and may have negative long term outcomes.

Home-based Speech Treatment For Parkinsons Disease Via Telerehabilitation : Clinical And Economic Outcomes.

Summary
Parkinson's Disease affects a person's ability to speak clearly. Speech pathologists can provide effective treatment for this speech disorder. Access to a speech pathologist, however, is difficult for many people with Parkinson's Disease due to their physical difficulties and the limited availability of speech pathology services in rural areas. This study demonstrates the use of telerehabilitation to deliver speech treatment to people with Parkinson's Disease in their own homes via the Internet.

Summary
A multidisciplinary team of researchers aim to develop a unique, advanced, computer-based speech device that speech pathologists can use to assess and treat a variety of speech disorders. The device will record the location, timing and pressure of tongue contacts against the roof of the mouth (palate) during speech using innovative sensors embedded in an artificial plate placed over the roof of the mouth. State-of-the-art 3D graphics will be used to display tongue-to-palate contacts to both spee ....A multidisciplinary team of researchers aim to develop a unique, advanced, computer-based speech device that speech pathologists can use to assess and treat a variety of speech disorders.

Summary
Speech difficulties are commonly experienced by people with multiple sclerosis (MS) and can have a devastating, restrictive effect on social interactions, work and education opportunities, ultimately reducing quality of life. Research has shown that a major factor underlying impaired speech in MS is disturbed functioning of the structures that articulate speech, particularly the tongue and lips.

Research has shown that a major factor underlying impaired speech in MS is disturbed functioning of the structures that articulate speech, particularly the tongue and lips. In order to effectively treat these speech disturbances, it is imperative that the nature and severity of the tongue and lip impairments be identified, so that specific treatment methods can be employed to directly target those impairments. The present project will use state-of-the-art technology to track and record movements of the tongue and lips during speech and to investigate how well the neural command pathways leading from the brain to the lip and tongue muscles are functioning in persons with MS. The results of the study will direct the development of more specific and effective speech therapy procedures that will empower persons with MS with intelligible speech.Read moreRead less
Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction ....Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction of two persons performing speech-hand gestures will be examined. Results will clarify how brain asymmetry affects gestural coordination in stutterers, how stuttering can be treated, and the hypothesis that speech and language evolved from a communication system based on hand gestures.

Summary
Stuttering is a chronic communication disorder that arises from problems in the brain processes that control speech. This research aims to use magnetoencephalography, a new and extremely fast method of brain imaging, to study the parts of the human brain that underlie speech production. By studying the brains of both child and adult stutterers the causes of stuttering will become more apparent. Ultimately, this research will lead to more effective treatments for stuttering.

We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated to others and would provide the basis for educational material and methods that would improve operator skill, safety, and performance. These individual improvements would provide overall benefits such as improved transport efficiency, reduced accident rates, saved lives and a reduction in related social costs.Read moreRead less
