Neuroimaging plays an important role in acute stroke diagnosis and management, but it is not routinely used in rehabilitation settings. Incorporating imaging information in rehabilitation planning may eventually translate to better outcomes after stroke. Here we review the prediction of outcomes after stroke using magnetic resonance imaging. There are clear and specific relationships between the anatomy of the stroke lesion and impairments at the time of scanning, and at later time points in recovery. However, most studies demonstrate these relationships in groups of patients at the chronic stage. In order to be useful for rehabilitation, neuroimaging needs to provide prognostic information for individual patients at a much earlier stage. Recent studies have used diffusion tensor imaging and functional neuroimaging to address this, with promising results. Combining neuroimaging with clinical and neurophysiological assessments may also be useful. Future work in this area may support the tailoring of rehabilita

Early rehabilitation is widely regarded as an important feature of effective stroke care. But what is ‘early’, and what kinds of therapies should, or can, we begin soon after stroke onset? In this interview, some of the barriers and drivers for early rehabilitation research and practice are explored.

Rationale Almost one-third of Australians need help to travel outdoors after a stroke. Ambulation training and escorted outings are recommended as best practice in Australian clinical guidelines for stroke. Yet fewer than 20% of people with stroke receive enough of these sessions in their local community to change outcomes. Aims The Out-and-About trial aims to determine the efficacy and cost effectiveness of an implementation program to change team behavior and increase outings by people with stroke. Design A two-group cluster-randomized trial will be conducted using concealed allocation, blinded assessors, and intention-to-treat analysis. Twenty community teams and their stroke clients (n = 300) will be recruited. Teams will be randomized to receive either the Out-and-About program or written guidelines only. Study Outcomes The primary outcome is the proportion of people with stroke receiving multiple escorted outings during therapy sessions, measured at baseline and 13 months postintervention. Secondary

Cognitive impairment after stroke is common and can cause disability with major impacts on quality of life and independence. There are also indirect effects of cognitive impairment on functional recovery after stroke through reduced participation in rehabilitation and poor adherence to treatment guidelines. In this article, we attempt to establish the following: ● whether there is a distinct profile of cognitive impairment after stroke; ● whether the type of cognitive deficit can be associated with the features of stroke-related damage; and ● whether interventions can improve poststroke cognitive performance. There is not a consistent profile of cognitive deficits in stroke, though slowed information processing and executive dysfunction tend to predominate. Our understanding of structure–function relationships has been advanced using imaging techniques such as lesion mapping and will be further enhanced through better characterization of damage to functional networks and identification of subtle white matter

Stroke survivors experience complex combinations of impairments, activity limitations, and participation restrictions. The essential components of stroke rehabilitation remain elusive. Determining efficacy in randomized controlled trials (RCTs) is challenging; there is no commonly agreed primary outcome measure for rehabilitation trials. Clinical guidelines depend on proof of efficacy in RCTs and meta-analyses. However, diverse trial aims, differing methods, inconsistent data collection, and use of multiple assessment tools hinder comparability across trials. Consistent data collection in acute stroke trials has facilitated meta-analyses to inform trial design and clinical practice. With few exceptions, inconsistent data collection has hindered similar progress in stroke rehabilitation research. There is an urgent need for the routine collection of a core dataset of common variables in rehabilitation trials.
