The theoretical prerequisites for the development of a monitoring system for determining the position movements and inclinations of the human head are discussed in the article. The description of the developed three-point model, which takes into account the structural and motor features of the cervical spine, is given. The choice of reference points for installing sensors has been substantiated. Variants of movement of these sensors are shown for different positions of the human head. The article describes the static and dynamic indicators necessary to assess the movements of the cervical spine. The developed system is described - a hardware and software complex for monitoring the position, movements and tilts of the human head; a structural diagram and used electronic components are presented. Prospects for further development and application of the developed system are considered.

The high social significance and the development of new methods for the diagnosis and diseases and injuries treatment of the cervical spine necessitate a detailed study of the mechanisms of change and the development of new methods for diagnosing its functional state. The article is devoted to one of the subjects of the Medical Radio Electronics Department (No. 24) of St. Petersburg State University of Aerospace Instrumentation (SUAI) research work. With the task of developing tools for the comprehensive study of physiology and pathophysiology of the cervical spine by registering muscle and other neuronal surface bioelectric activity of this area. In order to solve this problem, the prototype lay out of the hardware-software complex to study the physiology and pathophysiology of the cervical spine using registration of neuronal and muscle activity was developed.
