title: [Mechanism of the development of neuromuscular disorders in Itsenko-Cushing disease].
abstract: The results of electromyographic studies indicate that the affection of the neuromuscular system is seen in all the patients with Icenko-Cushing's disease. Changes in different indices of the electromyogram (EMG), i.e. denervation activity, a character of the summary EMG alteration, mean duration of the motor unit action potentials (MUAP), the number of polyphase action potentials, their amplitude and the MUAP synchronization in different spheres indicate a neurogenic character of this affection. It was shown that both denervation and reinnervation processes are more pronounced in the foot muscles than in the hand ones. The denervation process is seemed to be primarily developed in the foot muscles, followed by the hand musculature injury. Therefore, the changes in several EMG parameters may be seen during several stages of the disease in some muscles and not to be observed in the others.
