Boston, MassachusettsAges Any age - NCT01900132Recruiting
Electrical muscle testing for neuromuscular disorders
This study uses a quick, painless electrical test to measure muscle health in people with nerve or muscle disorders and in healthy volunteers. It aims to learn how these measurements change over time, which may help diagnose and monitor these conditions better.
Bethesda, MarylandAges 2–110 - NCT01316783Enrolling by invitation
Genetics study of obesity, diabetes, and heart risk
This study looks at genetic differences in adults from African diaspora groups to better understand risks for obesity, type 2 diabetes, and heart disease. You may help scientists learn why these conditions are more common in certain communities.
Bethesda, MarylandAges 18–120 - NCT02061306Recruiting
Study of gut microbes and genetics in infant celiac risk
This study looks at how gut bacteria, diet, and family background may relate to celiac disease risk in very young infants. It may help researchers understand why celiac disease happens and how it could be prevented or detected earlier.
Boston, MassachusettsAges Up to 6 months - NCT07877688Recruiting
Looking for rare disease genes in your DNA
This study will read the DNA (the genetic instructions) of people with rare diseases who do not yet have a diagnosis, to try to find the cause. It may help you get answers about your condition.
GenovaAges birth–17 years - NCT03545477Recruiting
Curved walking training for stroke, Parkinson's and hip fracture recovery
This study tests whether practicing walking in curved paths can help people recovering from a stroke, Parkinson's disease, or a recent hip fracture improve their balance and mobility. If you have one of these conditions and are in a rehabilitation program, this training might make everyday walking easier.
Lissone, Monza E BrianzaAges 18–90 - NCT02504853Recruiting
Study food allergy patterns and genetics over time
This study follows people with food allergy and some closely related or healthy people to learn how food allergy (and related conditions) develops over time. It may help researchers find causes and better ways to predict and treat food allergy.
Bethesda, MarylandAges 1 day–99 years - NCT02918188RecruitingPhase 2
Hydrogen therapy for steroid-resistant graft-versus-host disease
This Phase 2 study tests whether hydrogen therapy can improve symptoms in people with chronic graft-versus-host disease (cGVHD) who cannot tolerate steroid treatment. If steroids aren’t working or can’t be used, this trial may offer an alternative approach to help control the illness.
