Ion Channel Disorders

Ion channel disorders of muscles and nerves (channelopathies) are very rare disorders which may cause a variety of different symptoms including muscle stiffness, episodic weakness or paralysis, muscle twitching, or problems with balance.  Diagnosis is typically made by a detailed neuromuscular examination, electrodiagnostic testing (EMG), and often times, genetic testing.  There are symptomatic treatments for many of these disorders so early diagnosis is important.
