[Electromyography in spastic torticollis].
The EMG characteristics of convulsive activity in the sternocleidomastoid muscle in spastic torticollis vary in different stages of the disease. At the onset of the disease, the bioelectric muscle activity which accomplishes an involuntary turn of the head is registered. Eventually, as the morbid areas of myopathosis are formed in the "active" muscles and muscles preventing an involuntary turn, the electrogenesis of the latter becomes dominating. It is assumed that at the basis of this phenomenon lies a lowering of the excitation threshold in the neuromotor apparatus in the respective group of muscles with an appearance of a peripheral subordinating factor.
