RECRUITINGINTERVENTIONAL
Blood Flow Regulation and Neuromuscular Function Post-Stroke
About This Trial
The muscles of stroke survivors can fatigue faster compared to muscles in people who have not had a stroke, which can limit how long a person with stroke can perform tasks such as walking. This study will examine how blood flow is regulated to the exercising leg muscle post-stroke, because if the muscle does not receive enough blood flow it will become fatigued. Finally, the investigators will use a safe and simple non-invasive intervention called ischemic conditioning, which has known effects to improve blood flow to exercising muscle and determine the effects on muscle fatigue.
