Summary
Brief summary
This study is observing changes which occur to bone density and structure, muscle mass, and glucose metabolism (the way that the body converts sugars to energy), after stroke. We are investigating how these outcomes are influenced by physical activity after stroke. This information will be used in future designs of rehabilitation programs aimed at improving stroke patients' health and recovery.
