One of the most frequent consequences of a stroke is arm and hand motor impairment. In fact, more than 60% of stroke survivors have motor impairments on one side of the body, which may limit participation in everyday activities and quality of life. To date, only few studies look at what influences motor recovery,...
Some stroke patients have severe weakness in one arm and must rely on their less-affected arm for daily activities. Previous research has shown that in some patients, the less-affected arm also experiences weakness due to the stroke. This research is being done to find out if the less-affected arm can be...
This study aims to test the satisfaction and ease-of-use of an online mindfulness program. The program is specifically designed to increase mindfulness for stroke survivors and their caregivers or loved ones. We are particularly interested to obtain feedback on the content of the program and the website used to offer it. The feedback and suggestions...
85% of survivors of stroke experience walking issues, which limit their activities and participation. These issues include decreased coordination and slower walking, which might make people more prone to falls.
The objective of this study is to measure walking in people shortly after stroke and to identify which aspects...
The goal of this study is to understand how an individual’s cognitive function and brain structure may influence their ability to learn a new walking pattern. We hope to learn how people can best learn a new walking pattern when parts of the brain are damaged and cognitive function may...
Transcatheter aortic valve implantation (TAVI) has become a routine treatment option at specialized heart centers treating patients with severe aortic stenosis who are at high risk for surgical aortic valve replacement (SAVR). Medtronic has developed modifications to the Medtronic CoreValve System Transcatheter Aortic Valve frame and delivery catheter system to...
The purpose of this study is to understand how individuals control their walking after stroke while using visual information about their walking and while walking at different speeds. We hope to learn how people learn new walking patterns when parts of the brain are damaged and how this may change...
Critical Limb Ischemia (CLI) is defined as limb pain that occurs at rest, or impending limb loss that is caused by severe compromise of blood flow to the affected extremity. CLI is a major cause of death and disability (secondary to myocardial infarction, stroke and amputation). The mortality in patients...
The purpose of this study is to understand how a stroke affects walking balance and why people post-stroke fall more frequently. Findings from this study could inform the design of rehabilitation interventions to improve post-stroke walking ability.
We are looking for people who have had a stroke AND healthy adults who...
Prevention of stroke involves managing and treating risk factors. Most strokes are caused when blood flow to a portion of the brain is blocked. One place this often happens is in the carotid artery. This blockage is called atherosclerosis or hardening of the arteries. The purpose of this trial is...
Observational study to collect F/U imaging & clinical endpoint data from pts. who successfully completed baseline coronary IVUS (intravascular ultrasound) imaging in the dal-PLAQUE 2 (DP2) study to determine the correlation & clinical relevance of such imaging as related to coronary artery disease (CAD). Pts. who have had baseline angiography/IVUS,...
The primary objective of the study is to evaluate the safety and effectiveness of the Medtronic CoreValve® System (MCS) in a subset of subjects excluded from the U.S. Extreme Risk Pivotal Trial population due to one or more additional co-morbidities, as measured by a composite of all-cause death or major...
BACKGROUND: Evidence supporting a routine invasive practice paradigm for patients with stable ischemic heart disease (SIHD) is outdated. In strategy trials conducted in the 1970s, coronary artery bypass grafting (CABG) improved survival as compared with no CABG in SIHD patients with high-risk anatomic features. The relevance of these studies today...
