If you are interested in the broader "classic" view of these disorders, you might also find these papers insightful: myotonia

: It documents two cases of MuSK-antibody-positive myasthenia gravis where patients presented with both typical weakness and unexpected myotonic discharges on EMG testing. A fascinating and highly relevant paper on myotonia

: A deep dive into the multisystemic nature of the disease, including why some patients have "Christmas tree cataracts". : The study suggests that electrical myotonia isn't

: The study suggests that electrical myotonia isn't always a sign of a primary muscle membrane disease; it can also appear in specific autoimmune neuromuscular junction disorders.

While myotonia is classically associated with genetic muscle channelopathies or myotonic dystrophies, this paper reports an . It describes patients with Myasthenia Gravis (typically a disease of muscle weakness, not stiffness) who surprisingly exhibited electrical myotonia. This finding expanded the medical community's understanding of what should be included in the differential diagnosis for myotonic symptoms. Key Points from the Paper
