Louisville, KentuckyAges 18 years+ - NCT03614962Recruiting
Warmth and TENS to improve thinking in dementia
This study tests whether using a warmth treatment and a gentle electrical nerve-stimulation device (TENS) can improve thinking and memory in people with mild to moderate dementia. It may help by supporting brain and nerve function, alongside your usual care.
Hong KongAges 65 years+ - NCT03622879Recruiting
Mirror therapy plus mild skin stimulation for leg movement after stroke
This trial tests whether using a mirror together with mild electrical stimulation on the skin can improve lower-limb movement after stroke. You may be eligible if you can already lift your ankle a bit and walk independently, and if certain thinking, vision, and skin issues are not present.
Hong KongAges 55–85 - NCT03680872Recruiting
Brain-to-nerve study to improve hand movement after spinal injury
This trial tests a “neural bypass” approach to help restore hand movement and feeling in people with tetraplegia from a spinal cord injury. You would have repeated visits for brain/nerve testing and may receive study procedures to see if function improves.
Manhasset, New YorkAges 22–65 - NCT03713125Recruiting
Study of thinking skills in young children
This study looks at how children in kindergarten think and learn (often called “executive function”). They may be testing whether certain patterns in thinking and behavior relate to learning or development, and what can be measured in young children.
Nashville, TennesseeAges 4–9 - NCT03716128Recruiting
Testing bone hormone changes in people with kidney problems
This study checks how kidney disease affects bone health by measuring hormones like PTH and related blood markers. It may help doctors better diagnose bone problems that can occur with poor kidney function.
HerlevAges 18 years+ - NCT03725527Recruiting
Nerve block test to improve breathing after belly surgery
This trial studies whether a numbing injection near the abdominal muscle (rectus sheath block) helps your breathing and diaphragm function after elective upper belly surgery. If you qualify, you may receive or not receive this pain/nerve block as part of the study.
Asyut, Assiut GovernorateAges 18–50 - NCT03775837Recruiting
Ginseng extract to improve abnormal liver blood tests
This trial studies whether a Panax ginseng extract can improve liver-related blood test results in adults. It may help people with mildly to moderately elevated liver enzymes, while carefully excluding people with other liver causes.
YangsanAges 19–75 - NCT03778944Recruiting
Improving kidney graft function during donor kidney surgery
This study looks at ways to help a donated kidney work better after transplant. It is intended for people who are receiving a living-donor kidney transplant due to kidney failure.
CairoAges 18–60 - NCT03800017Recruiting
Muscle strength and exercise function in lung scarring
This study looks at how well skeletal (muscle) function supports exercise in people with interstitial lung diseases (including idiopathic pulmonary fibrosis). It may help better understand fitness and breathing limits, which can guide rehabilitation choices and future care.
Vancouver, British ColumbiaAges 40–80 - NCT03812913Recruiting
Brain and learning testing in girls with Turner syndrome
This study uses age-appropriate neuropsychological (thinking and learning) tests in girls to understand how brain functioning differs in Turner syndrome compared with isolated growth hormone deficiency. It may help doctors better assess learning and support needs.
