Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main goal of this program of research is to advance our understanding of how the severely damaged brain changes over the first 12-months post stroke. The investigators will determine 'who recovers', 'who does not recover', and 'why'

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The main goal of this program of research is to advance our understanding of how the severely damaged brain changes over the first 12-months post stroke. The prevalence and severity of stroke related arm disability is increasing and the prospect of optimal recovery is poor. Studies have demonstrated that stroke survivors with severe disability lack early indicators (\<7-days to \<1-month post-stroke) of a good prognosis, such as active movement at the shoulder and wrist and integrity of the corticospinal tract. This has propagated the clinical belief that this cohort are unlikely to functionally benefit from rehabilitation efforts. However, it is possible that indicators of potential for recovery - either neuroanatomical or clinical - may present in individuals with severe stroke later, that is beyond the early time-period. Indeed, there is increasing evidence of the potential for ongoing improvements in motor performance in response to intensive interventions that are undertaken 6-months or more post-stroke. This therefore, implies that there is some degree of untapped recovery potential. However, as very few studies have longitudinally explored the potential indicators of recovery in a severe cohort, the dynamic capacity of the severely damaged remains unknown. Thus, there is a need to determine 'who recovers', 'who does not recover', and 'why' to be able to promote optimal arm recovery in people with severe impairment after stroke. We will assess stroke survivors \<4-weeks, 3-months, 6-months and 12-months post stroke using a range of neuroimaging and clinical outcome measures. The findings from this study will build the foundations for more personalized health care options for people with severe arm impairment post stroke.
