View clinical trials related to Myotonic Disorders.
Filter by:Nondystrophic myotonias (NDM) are muscle disorders caused by genetic abnormalities in certain muscle cell membrane proteins. Individuals with NDM experience limited muscle relaxation, which causes pain, weakness, and impaired physical activity. The purpose of this study is to better characterize the clinical features and symptoms of NDM.
Myotonic dystrophy (DM) and facioscapulohumeral muscular dystrophy (FSHD) are inherited disorders characterized by progressive muscle weakness and loss of muscle tissue. The purpose of this registry is to connect people with DM or FSHD with researchers studying these diseases. The registry will offer individuals with DM and FSHD an opportunity to participate in research that focuses of their diseases. The registry will also help scientists to accomplish research on DM and FSHD and to distribute their findings to patients and care providers.
OBJECTIVES: I. Assess the efficacy of dichlorphenamide in the treatment of episodic weakness attacks in patients with hyperkalemic periodic paralysis, paramyotonia congenita with periodic paralysis, and hypokalemic periodic paralysis.
