ICD-11 definition : Generalised peripheral nerve hyperexcitability are a heterogeneous group of disorders
presenting as involuntary, continuous muscle overactivity. The clinical presentation
can include muscle cramps, fasciculations, myokymia (undulating movements of the skin
surface), and pseudomyotonia (delayed relaxation after a contraction). There are many
peripheral nerve hyperexcitability syndromes, with different pathogenesis that include
both genetic and acquired disorders. The most well-known is Isaacs syndrome, often
called acquired neuromyotonia.;
