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.

The Contribution Of Dopamine To Regulation Of Orofacial, Limb And Trunk Control: System Or Function Specific Effects?

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
Physiological And Neurophysiological Assessment Of Lip And Tongue Function For Speech In Multiple Sclerosis

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. In order to effectively treat these speech disturbances, it is imperative that the nature and severit ....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. 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
From Understanding The Mechanisms To Implementing Conservative Management Of Musculoskeletal Conditions

Summary
Musculoskeletal pain is the leading cause of disability internationally and outcomes are worsening. This work will take a unique approach to study back pain from the mechanisms that occur at the cellular level to the interaction between a person’s physiology and psychology to understand why pain fluctuates, to understand how treatments can be more appropriately tailored for individuals, and to test how people with back pain can be supported to change behaviours and achieve recovery.
Harnessing Neural Plasticity To Improve Functional Outcomes Following Burn Injury.

Funding Amount
$667,984.00
Summary
Burn is painful and leads to long-term functional impairment and increased chronic disease. Pain and peripheral injury induce changes in the brain that can be functionally beneficial or maladaptive, yet we know little about brain changes following burn injury. This project will identify the mechanisms and functional impact of neural plasticity after burn injury, and test the efficacy of a neural intervention to reduce pain and improve functional recovery following burn injury.
Reconsideration Of The Mechanisms Underlying Movement Changes With Pain

Funding Amount
$401,361.00
Summary
Pain changes the way we move. Although undisputed, there is a surprising lack of agreement regarding the underlying mechanisms. This project involves an innovative mix of neurophysiological methods to investigate how the drive to muscle cells from the nervous system is altered during pain. We aim to resolve the perplexing problem of how pain changes our ability to activate muscle. Our findings are likely to provide a clear understanding of the underlying mechanisms and guide rehabilitation.
Accurate Differentiation Of Acquired Speech And Language Disorders For Positive Rehabilitation Outcomes

Funding Amount

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.
