Congenital myotonic syndrome in children

Myotonic syndrome, also known as Thomsen disease, myotonia congenita, tonic muscular dystrophy syndrome, and Thomsen syndrome, is a relatively rare group of genetic diseases, including congenital myotonia , Atrophic rigidity, congenital paramuscular rigidity and other diseases. The common feature is that after voluntary contraction of voluntary muscles or after various mechanical or electrical stimuli are given, muscle tonic contraction does not immediately relax. Tonic contracted muscles are stiff, but without pain. Cold, excitement, anxiety, fatigue, and fever can all increase muscle stiffness. Tap the muscles with a percussion hammer, and muscle balls can appear. Tonic potentials can appear on the electromyogram.
