Who this trial is looking for
This trial is looking for adults who have had a stroke and still have weakness in one arm. Participants will receive treatments using low-intensity ultrasound to see if it helps with their motor skills.
Are You a Good Fit for This Trial?
You may be able to join if
- I am at least 21 years old.
- I have had my first stroke at least 6 months ago.
- I have weakness in one arm.
- My arm weakness measure is 62 or lower on a specific scale.
- I can test motor functions in my affected arm.
You may not be able to join if
- I have had strokes on both sides of my brain.
- I have another nerve or muscle disorder affecting my arm.
- I have a history of serious depression or other mental health issues.
- I have been diagnosed with dementia.
- My blood pressure is too high despite treatment.
- I have factors that are unsafe for MRI or ultrasound.
- I am part of another stroke recovery study.
- I am pregnant.

About This Trial
The goal of this research study is to optimize the parameter of Low-Intensity Focused Ultrasound Stimulation (LIFUS) that is most effective in changing cortical excitability and motor learning skills in patients who suffered a stroke. The researchers hope to answer two questions.
* with increasing power, would LIFUS be more effective?
* with the same power, what LIFUS timing is the best
