AB  - OBJECTIVE: To determine the electromyographic patterns of motor tics in children. 
      MATERIAL AND METHODS: 130 patients were examined, which were divided into 3 
      groups: the 1st group included 21 patients with motor tics; the 2nd group 
      included 87 patients with motor-vocal tics; the 3rd group included 22 patients 
      with Tourette's syndrome (ST). The control group consisted of 35 healthy 
      children. Clinical methods for assessing the severity and semiotics of tics were 
      used, including the YGTSS scale, hyperkinesis counting in 20 minutes, cutaneous 
      electromyography (EMG) in rest and exercise modes with turn-amplitude analysis. 
      RESULTS: The following EMG patterns of tic hyperkinesis in the resting mode were 
      found: 1) the amplitude of the background activity exceeds the values in the 
      control group (p<0.05); 2) in case of clonic tics, a high-amplitude volley 
      activity (VA) arises simultaneously in the form of spindles with a duration of 
      10-30 ms with an amplitude of 500-2500 muV; 3) with dystonic tics, volleys in the 
      form of rhombuses with a duration of 100-1000 ms and an amplitude of 1000-3000 
      muV; 4) volley-slow wave had a duration of 307.2+/-109.6 ms and an amplitude of 
      540.3+/-238.6 muV. In the mode of physical activity, VA increases, which is 
      maximally expressed in amplitude on the circular muscle of the eye and the 
      superficial flexor of the fingers in patients with CT (p<0.05). Analysis of 
      correlations established an inverse relationship between the amplitude of VA and 
      the number of hyperkinesis in 20 minutes. CONCLUSION: Qualitative and 
      amplitude-time analysis of EMG makes it possible to objectify the disease, to 
      isolate patients with CT from chronic motor-vocal tics and to model the 
      prognosis. Probably, the tic can act as a compensatory manifestation of excessive 
      impulsation of cortical-subcortical genesis.
