The study showed that a forearm movement in 6 year old children with speech disorders is to a greater extent achieved by the biceps work as opposed to textbook notions of the muscles work when bending one’s arm at the elbow. However, children are able to learn to control their muscle tone and ensure intermuscular coordination when mastering purposive movements. Interference pattern electromyography reveals specific features of antagonist muscles work, providing individual assessment of the outcomes of children mastering purposive movements. Its use ensures a realization of one of the feedback types. More precise control of the forearm movement and intermuscular coordination improvement are ensured by the joint functioning of the antagonist muscles when mastering ball skills. Computer games without methodical support do not provide the required intermuscular coordination due to the emerging uncertainty and may result in incorrect movement patterns in children with learning difficulties. The study produced fundamentally new data revealing the nature of the biceps and triceps work when mastering purposive movements in children with speech disorders. It can serve as a starting point for further research in the field of comparative analysis of the abilities of children with learning difficulties accounted for by various health statuses.

Keywords: children with speech disorders, ball exercises, computer games, biofeedback.
