Neuromyotonia and myokymia
Generalized neuromyotonia is usually an autoimmune disease characterized by widespread muscle stiffness and delayed muscle relaxation after voluntary movement. It is accompanied by continuous muscle twitching known as myokymia. Both conditions are typically related to disorders of the voltage-gated potassium channel and caused by autoimmune, toxic, or genetic processes. Whereas neuromyotonia is specific to these disorders, myokymia can be seen in many neurologic conditions.
