Reduction in incident stroke risk with vigorous physical activity: evidence from 7.7-year follow-up of the national runners' health study.

abstract：BACKGROUND AND PURPOSE:Central autonomic dysfunction increases stroke morbidity and mortality. We aimed to investigate whether poststroke autonomic dysfunction graded by Ewing battery can predict clinical outcome.
