WebApr 14, 2024 · People with myotonic dystrophy experience progressive muscle weakness and repeated episodes of painless muscle stiffness called myotonia. Investigators at Massachusetts General Hospital (MGH) recently used a targeted drug to restore muscle strength and correct myotonia in mice with myotonic dystrophy. Webdischarges. Myotonic dystrophy and myotonia congenita share both clinical and electrodiagnostic myotonia. Paramyotonia congenita and hyperkalemic periodic paralysis are associated with clinical paramyotonia and electrical myotonia. Acid maltase deficiency often produces myotonic potentials with-out clinical evidence of myotonia or paramyotonia.
