title: Exercise rehabilitation after stroke.
abstract: Stroke is a leading cause of disability that results not only in persistent neurological deficits, but also profound physical deconditioning that propagates disability and worsens cardiovascular risk. The potential for exercise-mediated adaptations to improve function, fitness, and cardiovascular health after stroke has been underestimated: it represents an emerging arena in neurotherapeutics. To define the health rationale for cardiovascular (aerobic) exercise, we first outline the impact of debilitating secondary biological changes in muscle and body composition on fitness and metabolic health after stroke. We provide an overview of evidence-based advances in exercise therapeutics, with a focus on task-oriented models that combine a progressive aerobic conditioning stimulus with motor learning to improve multiple physiological domains that determine longitudinal outcomes after stroke. Although progress in development of safe and effective exercise strategies is advancing, fundamental questions regarding dose intensity, prescription to optimize central and peripheral neuromuscular adaptations, and the public health value of exercise in secondary stroke prevention remain unanswered. Key issues steering future research in exercise neurotherapeutics are discussed within the context of initiatives to facilitate translation to community-based studies, requisite for dissemination.
