Stroke recently declined from the third to the fifth leading cause of death in the United States. However, Stroke remains the leading cause of long-term disability and is among the most expensive chronic diseases, costing the US approximately 34 billion dollars per year. The decrease in stroke-related mortality has led to an increase in stroke survivors, and it is estimated that the overall prevalence will increase by 25% by 2030 to a record 11 million stroke survivors. Importantly, two-thirds of the nearly one million Americans experiencing ischemic stroke or transient ischemic attack (TIA) will regain functional independence. In these patients, engagement in habitual purposeful physical activity (PA) is a powerful means of secondary stroke prevention.
