EMPOWER: Effects of Weight Loss and Exercise Post-stroke

Description

The prevalence of obesity among U.S. adults is \~40% and is projected to climb. It is well documented that obesity is associated with increased levels of disability as well as risk for numerous adverse health-related outcomes; including occurrence of stroke and all-cause mortality. Obesity is highly prevalent in stroke survivors (\~30-45% of stroke survivors have BMI\>30) and is associated with reductions in physical function and increased disability. Furthermore, neurological sequelae following stroke result in a myriad of residual impairments that contribute to significant reductions in physical activity, which further increase the risk for obesity. The alarmingly high (and increasing) rates of obesity amongst stroke survivors represents an area of critical clinical need and, despite an abundance of information regarding weight loss approaches in neurologically healthy individuals, there is a lack of information regarding the impact of intentional weight loss on overweight and obese survivors of stroke. Thus, the purpose of this study it investigate the effect of varying weight loss approaches on physical function and psychosocial outcomes in chronic stroke survivors.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. age 35-85
  • 2. stroke at least 6-months prior
