Neuromyotonia is spontaneous muscular activity resulting from repetitive motor unit action potentials of peripheral origin.
Neuromyotonia is considered to be one of these with accumulating evidence for autoimmune origin over the last few years.
Some neuromyotonia cases do not only improve after plasma exchange but they may also have antibodies in their serum[?] samples against voltage-gated potassium channels.

 CIGNA - Neuromyotonia
Neuromyotonia is a rare neuromuscular disorder characterized by abnormal nerve impulses from the peripheral nerves.
Neuromyotonia is characterized by involuntary continuous muscle fiber activity (fasciculations) that cause stiffness and delayed relaxation in the affected muscles.
Neuromyotonia may be treated with anticonvulsant drugs such as phenytoin, or with carbamazepine, which may stop the abnormal impulses and prevent the symptoms from reoccurring.

Neuromyotonia (medical condition): A condition which is characterized by myotonia caused by electrical activity of the peripheral nerve.
Neuromyotonia is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH).
This means that Neuromyotonia, or a subtype of Neuromyotonia, affects less than 200,000 people in the US population.

Neuromyotonia (NMT) is an uncommon syndrome of spontaneously occurring muscle activity of peripheral nerve origin, which can be triggered by voluntary or induced muscle contraction in which hyperexcitability of peripheral nerves leads to incapacitating muscle twitching, cramps, and weakness.
Neuromyotonia (NMT) is a rare disorder of unknown cause described by Issacs1 in which hyper excitability of peripheral motor nerves resulting in continuous muscle fiber activity which leads to incapacitating muscle twitching, cramps, and weakness.
Neuromyotonia also occurs at increased frequency with certain tumors that are well recognized to produce autoantibody-mediated, paraneoplastic disorders of the peripheral nervous system3.

Neuromyotonia, with all its synonyms is an enigmatic entity, in part because of its remarkable clinical pleomorphism, uncertain natural history and anecdotal response to various therapies.
The term 'Neuromyotonia' found its place in the early papers of Zondeck[1] and Brown,[2] but it was Isaacs[3] who described the condition in detail.
We are documenting here 20 cases of neuromyotonia with classical electromyographic picture and their follow-up with response to various therapies.

 User:Erdem Tüzün
In neurology, his research interests are autoimmune diseases of peripheral nerve and neuromuscular junction (particularly myasthenia gravis and neuromyotonia) and new techniques in electromyography / nerve conduction studies.
He has studied in Oxford University as an academic visitor to perform a research project about the involvement of antibodies to central nervous system antigens in central nervous system disorders.
His major contributions are demonstration of antibodies against voltage-gated potassium channels in some patients with limbic encephalitis, identification of the autoimmune etiology of neuromyotonia and demonstration of autoantibodies against thalamic structures as a causal factor for Morvan's syndrome and application of F tacheodispersion method in diabetes mellitus patients with subclinical neuropathy for early diagnosis.

Neuromyotonia (Isaacs' syndrome) appears to be due to antibody-induced blockade of potassium channels along peripheral axons.
Generalized myokymia and neuromyotonia may be seen in the absence of traditional disease of peripheral nerves or motor neurons as in Isaacs' syndrome.
Such generalized acquired neuromyotonia has been shown to be associated with autoantibodies directed against potassium channels in peripheral motor axons.

The EMG confirmed the absence of fasciculations and showed the presence of doublets, widespread irregular grouped motor unit discharges, and complex repetitive discharges with mixed widespread myotonic discharges which was consistent also with a diagnosis of Isaacs' syndrome or neuromyotonia.
The patient's father also had a history of cramps, but the patient probably did not have the familial form of the disease because of the good response he had to treatment with plasma exchange, as outlined later.
Also the anti-GAD antibodies seen in Stiffman's syndrome are not seen in neuromyotonia.

We present here a case of an acquired paraneoplastic neuromyotonia associated with thymoma and clinically manifested myotonia-like muscle stiffness and an unusual electrophysiological pattern of neuromyotonic discharges that were evoked voluntarily or with electrical stimulation but were absent spontaneously and were not elicited by needle displacement.
Though it is not an easy task to define the discharges in hyperirritable neuromuscular disorders, actual definitions of neuromyotonic discharges emphasising their spontaneous occurrence or initiation by needle movement should, however, be reconsidered and modified.

"Neuromyotonia is a rare condition of spontaneous and continuous muscle fibre activity of peripheral nerve origin.
This review highlights the classical clinical, electrophysiological and immunological features of this disorder from what is currently known in the literature to date, and also from the author's own patients' studies.
Neuromyotonia is best classified as a moderately severe disorder of peripheral nerve hyperexcitability, with electromyographic features of spontaneous, continuous, irregularly occurring doublet, or multiplet single motor unit (or partial motor unit) discharges, firing at a high intraburst frequency (30-300Hz).
