Muscle Atrophy, Physical Performance and Glucose Tolerance Post Stroke

The Summary of Purpose was updated.
New
Stroke, a leading cause of disability in the aging population, increases the risk for diabetes, subsequent stroke recurrence, and cardiovascular disease complications. The downsizing of private and federal health care resources, along with the anticipated increase in stroke rates as our population ages, mandate that alternative strategies be developed to reduce the public health burden of stroke. This pilot study may facilitate our knowledge of the timing of paretic leg muscle atrophy, fiber type shift, and the progression of worsening of glucose tolerance after stroke. Knowledge of the skeletal muscle changes occurring in the sub-acute stroke period is essential to create new guidelines incorporating exercise rehabilitation, much like cardiac rehabilitation, in order to facilitate and improve the health care of veteran stroke survivors.

New
The vast majority of cerebrovascular accidents are reported in persons older than 55 years of age and occur in over 780,000 persons each year in the U.S. As our adult population ages, the number of strokes in the United States is anticipated to double, reaching nearly 1.5 million annually by the year 2050. Following stroke, patients remain at continued high risk for recurrent stroke with almost a third of them suffering recurrent stroke within 5 years, even despite optimal medical management. Age and cardiac disease are among the most important longitudinal predictors of cardiovascular health outcomes and survival after stroke. Notably, 75% of chronic stroke survivors have residual disability emphasizing the need for rehabilitation strategies. Knowledge of the skeletal muscle changes that occur in the early phases after stroke is essential to create new guidelines which incorporate exercise rehabilitation, much like cardiac rehabilitation, in order to facilitate and improve the health care of stroke survivors.
