Summary
Gold-standard testing protocols for assessing standing balance, gait and activities of daily living is often a primary focus for therapeutic interventions. They often incorporate multiple force platforms and 3D motion analysis, which provide valuable information however the time, cost and infrastructure required excludes their use in normal clinical practice. This fellowship examines the potential efficacy of low cost, widely available alternatives such as video gaming devices and smart phones.
We stand without falling by using silent senses from muscles and the balance organs of the inner ear to unconsciously detect and control our movements. Since the leg muscles provide both the force and the sense, and critically rely on good circulation, they are vitally important. I propose to study how these sensory and muscle functions are used to control balance, posture and stepping reflexes, making it easier to identify older people who will fall and design new preventative strategies.
Vestibulo-ocular Reflex Physiology, Pathology And Rehabilitation

Summary
A sensation of movement from the inner ear is used to stabilise vision during head movements. Without it, every time you walk, run, or drive on a bumpy road, the world would appear to bounce. It can be debilitating when this sense doesn't work due to various diseases. This research examines how this sense works normally and the factors important for self-repair after injury. This work will also develop training exercises using a device for take-home balance rehabilitation.
A Balancing Act: A Three-pronged Approach To Vestibular Assessment

Summary
Vertigo and imbalance are common and disabling symptoms of vestibular (balance) dysfunction. This project will investigate three aspects of vestibular function: by searching for new balance reflexes, revealing the pattern of vestibular deficits in patients with a common form of vertigo caused by migraine, and exploring the impact of vestibular disease on thinking and memory. This research will improve our understanding of the vestibular system and facilitate the diagnosis of episodic vertigo.
Multisensory Determinants Of Postural Instability And Falls In Older Adults; Prevention And Rehabilitation

Summary
With an increased longevity of the population, age-related health problems, such as falls, are a significant socioeconomic issue to be addressed. Many sensory systems (e.g. vision, hearing, balance) are known to gradually become disrupted as a consequence of ageing. This project will investigate the consequences of declining sensory systems for balance control in older adults and to develop technology to prevents falls in them.

Summary
A sensation of movement from the inner ear is used to stabilise vision during head movements. Without it, every time you walk, run, or drive on a bumpy road, the world would appear to bounce. It can be debilitating when this sense doesn't work due to various diseases. This research examines what causes these disorders and how the brain responds to help recovery. A diagnostic technique, that we will develop for wide clinical use, will be used to assess and identify treatments.
A New Paradigm To Prevent Intracranial Hypertension

Summary
Increasing brain pressure after stroke or other forms of brain injury can cause further injury and death. Body cooling by 4-5 0C (hypothermia) for 12-24 hours saves lives after some forms of brain injury, but may have major side effects. We found that 2 hour hypothermia has a long-lasting effect preventing pressure elevation. We will determine the best temperature and duration of hypothermia in a stroke model and use imaging to confirm findings in patients, with a view to later human trials.
Understanding The Regulation Of Cell Polarity In Development And Cancer

Summary
Cell polarity is the property of cells to be spatially oriented in a tissue or organ. We have now shown that the gene Scribble, a key regulator of cell orientation, may keep tumour development in check. In this proposal, we will examine how disruption of Scribble and associated molecules affects normal development and promotes cancer using a combination of tissue culture studies and a newly established mouse model. These studies may provide novel targets for therapeutic intervention in cancer.
