The MRIs showed increased blood oxygenation and flow in the brain stem and cerebellum of the stroke survivors who had used the treadmill but not in those who did stretching.

To explore the changes of cerebral blood flow, collateral compensative capacity and the artery recanalization in patients with acute middle cerebral artery (MCA) stem occlusion.

By detection and computation, we found the patients who got cerebellum atrophy or brain stem atrophy often accompanied by the narrow diameter and less blood-flow of VA.
