Weight Loss and Exercise for Stroke Survivors
(EMP Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how different weight loss strategies can improve physical and emotional well-being in stroke survivors. Participants will either follow a diet plan, combine the diet with a special exercise program designed to boost leg strength and walking ability (part of the Lifestyle Management Program), or be placed on a waitlist before starting one of these methods. The trial aims to determine which approach most effectively helps stroke survivors become fitter and feel better. It suits individuals who had a stroke at least six months ago, can walk without assistance, and have a BMI over 25. As an unphased trial, this study offers a unique opportunity to contribute to valuable research that could enhance recovery strategies for stroke survivors.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, if you are currently prescribed anti-seizure medications, you may not be eligible to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that lifestyle programs for stroke survivors are generally safe. One study found that a structured weight-loss program with meal replacements helped participants lose weight without major side effects. Another review highlighted that lifestyle changes are a key way to prevent further strokes and are well-tolerated by participants.
For the exercise component, known as POWER training, studies have shown it is safe for stroke survivors. Research indicates that this program can improve muscle strength and walking ability without causing injuries or health problems. Exercise programs like this are considered safe and beneficial for stroke patients.
In summary, both the lifestyle changes and exercise program in the trial have been shown to be safe in previous studies. They are well-tolerated by participants and help improve health outcomes.12345Why are researchers excited about this trial?
Researchers are excited about the Lifestyle Management Program for stroke survivors because it combines innovative approaches to improve recovery. Unlike standard care for stroke recovery, which often focuses on medication and basic physical therapy, this program integrates a structured diet plan with a unique rehabilitation method called POWER training. POWER training is distinctive due to its focus on high-velocity, high-intensity exercises, like leg presses and jump training, which aim to enhance post-stroke muscular and locomotor function. This approach could lead to more significant improvements in mobility and quality of life for stroke survivors compared to traditional methods.
What evidence suggests that this trial's treatments could be effective for stroke survivors?
Research shows that lifestyle programs focusing on diet and exercise can help stroke survivors lose weight and improve their health. This trial includes a "DIET" arm, where participants engage in a lifestyle management program focusing on diet alone, and a "DIET+Exercise" arm, which combines diet with the Post-stroke Optimization of Walking using Explosive Resistance (POWER) training. Studies have consistently shown that these programs can lead to a 5% to 7% weight loss, significantly enhancing physical function. Both diet alone and diet combined with exercise improve walking ability, as measured by the six-minute walk test.
Regarding exercise, the POWER training program, part of the "DIET+Exercise" arm in this trial, greatly increases strength in stroke survivors. Participants in previous studies saw a 54% improvement in their weaker limbs and a 57% improvement in their stronger limbs. This type of training also helps improve overall movement and function, making it a promising way to aid recovery after a stroke.35678Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for chronic stroke survivors aged 35-85 with a BMI over 25, who can walk unassisted at certain speeds and have some lower extremity weakness. They must pass an exercise test and get clearance from the study physician. Excluded are those with severe heart conditions, visual impairments, uncontrollable high blood pressure, seizure history, other neurological issues or major health problems.Inclusion Criteria
