Summary
A population-based study of prevalence of muscle contracture will provide helpful information to health providers about the magnitude of the problem of contracture. This information will focus research efforts, and help health care providers to allocate resources appropriately. Recent studies have found that current treatments for contracture often provide transient or no effects. This project will test a promising new direction in treatment of contracture in people with multiple sclerosis.
What Is The Function Of The Tibialis Posterior Muscle And Tendon During Walking And How Does It Affect Disorders Of The Foot

Summary
The tibialis posterior (TP) muscle is important for foot function and is often implicated in foot and ankle problems. We will investigate the function of TP during gait with specific reference to foot posture. In particular we will examine the mechanical function of the muscle and tendon in different foot postures and commonly used treatment modalities such as (footwear and foot orthoses).
My primary research interest is in the effectiveness of physiotherapy interventions. A second research interest is in the mechanical and architectural properties of human muscles and tendons.

Summary
Muscle contracture - abnormal stiffening of muscles - is common in many conditions, including stroke, spinal cord injury and multiple sclerosis. Contractures can be very disabling. The mechanisms of muscle contracture are poorly understood. This study will determine whether contractures of calf muscles in people with stroke, spinal cord injury and multiple sclerosis are due to changes in the mechanical properties of muscle fascicles or tendons.
Tendon injury is one of the most common health problems worldwide and affects almost everyone at some point in particular the aging populaiton. However, the current treatments are not well defined. We identifed an extracellular molecules SPARC that potentially plays an important role in tendon function. The aim of this study is to examine the role of SPARC in tendon development, homestasis and degenerative using transgenic mice and gene therapy. We predict that SPARC will have therapeutic value ....Tendon injury is one of the most common health problems worldwide and affects almost everyone at some point in particular the aging populaiton.

Rotator cuff (RC) tendon disease is a huge burden on the healthcare system in Australia and a major cause of morbidity in our aging population. Disorders of the RC are the most common cause of shoulder pain, which accounts for 1.2% of all visits to general practitioners. The prevalence of RC pathology increases with age to reach 30-50% by the seventh decade of life and a staggering 70-80% by the ninth. While most cases are treated conservatively, there are over 12,000 RC repair surgeries perform ....Rotator cuff (RC) tendon disease is a huge burden on the healthcare system in Australia and a major cause of morbidity in our aging population. Disorders of the RC are the most common cause of shoulder pain, which accounts for 1.2% of all visits to general practitioners. The prevalence of RC pathology increases with age to reach 30-50% by the seventh decade of life and a staggering 70-80% by the ninth. While most cases are treated conservatively, there are over 12,000 RC repair surgeries performed annually in Australia, with patients being committed to a prolonged convalescence. There are no drug therapies to specifically treat RC or other tendon injuries and many surgical repairs fail within 12 months. The limited treatment options for RC and other tendon disorders stems from a lack of knowledge of the molecular changes that precede and lead to rupture. It is recognised that the content of sulphated sugars or glycosaminoglycans (GAGs) on proteoglycans in tendon is the strongest predictor of the tisues strength. Accumulation of GAG is a well-recognised feature of torn tendons in man. The changes in proteoglycan synthesis and breakdown that precede and lead to tendon rupture have not been defined. We have developed a new model of shoulder tendon injury in sheep that induces regional degeneration mimicking that seen in human RC disorders. We have found changes in expression of specific proteoglycans and their degradative enzymes in early tendon disease. The current project will use this model in combination with a novel culture system and recently developed genetically modified mice to determine for the first time the changes that occur over time in proteoglycan metabolism that are responsible for tendon degeneration that leads to rupture. Successful completion of these studies will identify biomarkers to monitor disease progression and a platform for the development of new therapeutic strategies to treat this debilitating disorder.Read moreRead less
Degeneration and tearing of tendons such as the rotator cuff is a major health issue in working and ageing Australians. Tendon ruptures are preceded by degenerartive change which contributes to the poor success with surgical repair. There are very limited medical treatments available. We have developed an animal model mimicing human tendon dgeneration and will determine the utility and mechanisms of action of using a novel new therapy, stem cells in modulating degenerarion and aiding repair.

Summary
Tendinopathy has a significant patient morbidity, which is a clear burden to the Australian economy. A better fundamental grasp of tendon tissue biology is urgently required. This study will enable us to establish the role of matricellular protein SPARC in tendon function, thus enhance the understanding of tendon biology and enable translation of the bench work to potential clinical applications.
