Conference Paper
Background and aim: In humans, inactivity after stroke is associated with accelerated bone loss. The aim of this study was to investigate skeletal effects of brain infarct, using a proven animal model. Hypothesis: post-stroke, skeletal parameters of left and right femurs would be compromised, but physical activity unaffected, to suggest a skeleta...
Article
Background: Returning to work is an important outcome for stroke survivors. Objectives: This sub-study of a randomised controlled trial aimed to provide characteristics of working-age stroke participants and identify factors associated with return to work at 12 months. Methods: We used paid employment data collected as part of A Very Early Reh...
Article
Purpose The context of implementation plays an important role in the delivery of optimal treatments in stroke recovery and rehabilitation. Considering that stroke systems of care vary widely across the globe, the goal of the present paper is to compare healthcare providers’ priority of key areas in translating stroke research to clinical practice a...
Article
The impact of out-of-bed upright activity on outcomes in ischemic stroke patients with severe extra- and intracranial stenosis or occlusion is unknown. Using ultrasound findings from a cohort recruited to A Very Early Rehabilitation Trial (AVERT) which compared higher dose very early mobilisation (VEM) to usual care (UC), we aimed to explore the as...

Aims Pre-diabetes is a common condition that affects about 16.4% of Australian adults. Hyperglycaemia is a strong risk factor for the development of stroke. Metformin XR is an approved medication to treat type 2 diabetes in Australia but not pre-diabetes. Additionally, whether it is tolerated following a stroke is unclear. In this pilot study, we a...

Background: Rehabilitation wards are unique healthcare environments where patient activity is encouraged to improve recovery. Little is...
Article
Finding, testing and demonstrating efficacy of new treatments for stroke recovery is a multifaceted challenge. We believe that to advance the field, neurorehabilitation trials need a conceptually rigorous starting framework. An essential first step is to agree on definitions of sensorimotor recovery and on measures consistent with these definitions...
Article
The first Stroke Recovery and Rehabilitation Roundtable established a game changing set of new standards for stroke recovery research. Common language and definitions were required to develop an agreed framework spanning the four working groups: translation of basic science, biomarkers of stroke recovery, measurement in clinical trials and interven...
Article
Stroke recovery is the next frontier in stroke medicine. While growth in rehabilitation and recovery research is exponential, a number of barriers hamper our ability to rapidly progress the field. Standardized terminology is absent in both animal and human research, methods are poorly described, recovery biomarkers are not well defined, and we lack...

Introduction: Deranged glycaemic control is common post-stroke, increasing risks of recurrent stroke and development of diabetes. The aim of the study is to examine glucose metabolism in relation to body composition, physical activity and sedentary time post-stroke. Patients and methods: Observational study: Non-diabetic adults, unable to walk i...

Background: Care gaps for stroke lead to preventable disability and deaths. The Victorian State Government implemented a program of employing clinical Facilitators on a fixed-term basis for up to three years (2008-2011) in eight hospitals to improve stroke care.

Conference Paper
Background and aims: Substantial bone loss and structural deterioration occurs, and risk of fracture increases 7-fold 12 months after stroke. However, acute changes to bone structure have not been described. The aim of this ongoing prospective study is to determine the timing and magnitude of loss of bone mass and structure soon after stroke. Met...
Conference Paper
Background: One-third of stroke patients develop hyperglycaemia soon after hospitalisation. Of these patients, up to two-thirds experience impaired glucose tolerance (IGT), impaired fasting glucose (IFG) or diabetes by three months after stroke1. Muscle loss and immobility after stroke may contribute to development of IFG and IGT. Aims: To investi...

Methods This was a cross-sec...
Conference Paper
Background: Poststroke bone loss is pronounced, contributing to increased fracture risk. Many stroke patients also experience insulin resistance. The emergence of these health issues are unknown but physical activity can maintain or improve bone mineral density (BMD) and insulin sensitivity in chronic stroke patients, and may be of benefit in the a...
