Muscular channelopathy

This study is testing a handheld device called mScan that uses a tiny, painless electrical current to measure muscle health. Researchers want to see if it can give similar results to an MRI, but faster and more conveniently. The study involves 150 adults with and without muscle d…

This study looks at whether a personalized strength exercise program can improve muscle function and reduce weakness attacks in adults with hypokalemic or hyperkalemic periodic paralysis. Over 24 weeks, 36 participants will be tested at the start, at 12 weeks, and after 12 weeks …

This study tests a new extended-release form of mexiletine (mexiletine PR) against the standard immediate-release version in people with non-dystrophic myotonias, a group of rare genetic disorders that cause muscle stiffness. About 24 adults aged 16 and older will take each versi…

This study looks at whether a longer fasting period before an upper endoscopy can lower the risk of stomach contents entering the lungs (aspiration) in people taking GLP-1 receptor agonists (like Ozempic or Wegovy). Researchers at Mayo Clinic will check the stomachs of 150 adults…

This research study at Boston Children's Hospital is looking at the genes and proteins involved in congenital myopathies—rare muscle diseases that are present from birth. Researchers will analyze DNA from up to 4,000 participants, including patients and their family members, to f…

This study is looking at whether a molecule in the blood called miR-1 can help doctors understand how muscle diseases like Duchenne muscular dystrophy and myotonic dystrophy are progressing. Researchers will compare miR-1 levels in 104 people, including patients with different mu…

This study follows 150 people aged 7 and older with RYR1-related muscle disorders for 3 to 5 years. Researchers will collect medical history, perform physical exams, and use questionnaires, activity trackers, and tests of heart, lung, and muscle function. The goal is to better un…
