Charcot-Marie-Tooth disease type 4J

This study tests a device called Walkasins, worn on the lower legs, that vibrates to give sensory feedback about foot pressure. The goal is to see if using it daily for six months improves balance and walking in 200 adults aged 55+ with peripheral neuropathy. Participants will do…

This study aims to learn more about rare inherited disorders that affect the brain, spinal cord, muscles, and nerves. Researchers will collect medical history, perform exams, and run genetic tests on up to 3,500 participants. No new treatments are tested; the goal is to better un…

This study aims to see if a quick bedside sensory test can predict which painkiller—pregabalin, duloxetine, or a placebo—works best for people with nerve pain in their feet. About 190 adults with diabetic, chemotherapy-related, or idiopathic nerve pain will try each treatment for…

This study looks at how nerves work in people with Charcot-Marie-Tooth disease and other nerve disorders like CIDP. Researchers will use special electrical tests and ultrasound to measure nerve and muscle changes. The goal is to better understand these conditions, not to test a n…

This study is collecting information from 4,000 adults with peripheral neuropathy (nerve damage) to better understand the condition. Researchers will combine standard tests with nerve ultrasound to see if it helps diagnose and track the disease. No new treatments are being tested…

This study follows 20 people with a rare nerve disease called CMT4J for up to 2 years. Researchers will track symptoms and health changes to better understand how the disease progresses. The goal is to find better ways to measure the disease, which could help design future treatm…

This study is collecting nerve samples and biofluids from 400 people with ALS or peripheral neuropathies to find biological markers for early diagnosis and disease tracking. By analyzing individual cells, researchers hope to identify molecular changes that happen before symptoms …

This observational study follows up to 5,000 people with Charcot Marie Tooth disease (CMT) types 1B, 2A, 4A, and 4C over five years. Researchers will measure symptoms, nerve function, and disability using special scales to understand how the disease changes over time. The goal is…

This study aims to find new genes that cause Charcot-Marie-Tooth disease (CMT) and discover why symptoms differ among people with the same genetic change. Researchers will analyze DNA from up to 1,050 participants to identify genetic modifiers and unknown causes. The goal is to b…
