Forecasting the state of a human operator during his activities in various conditions, including extreme ones, is a necessary element of professional selection. Such a forecast can be carried out using special hardware and software that combines the ability to assess the functional state and provide special interventions. In addition, such a combination of capabilities is promising for use for rehabilitation purposes. The goal of the work was to design a system that meets these requirements. A multi-purpose medical device has been developed, including measuring, monitoring, diagnostic, rehabilitation equipment, and means of influencing a person to complex postural loads of a passive type. The hardware and software complex provides devices for ongoing (real-time) assessment of a person’s functional state in the control system and providing interventions using biofeedback. It consists of three main parts: a rotary table, an autonomous system for monitoring the physiological and positional parameters of the patient, and a set of standard instruments for recording the physiological parameters of the patient. The autonomous system for monitoring the physiological and positional parameters of the patient is designed for synchronous recording of the cardiac rhythmogram (based on the ECG signal), respiratory phases and tilt of the head end of the table. A set of standard instruments for recording the physiological parameters of the patient is designed for dynamic assessment of the patient's condition before, after and during the procedure. This kit may include various diagnostic instruments. Individual selection of influences is carried out by adjusting the movement parameters of the turntable table. The speed of movement, the angle of inclination, the direction of movements and the period of their repetitions can change. In this case, it is not so much the absolute values of certain medical parameters that have diagnostic significance, but rather the degree of their change during postural influences and the rate of recovery after the patient returns to the starting position. These parameters are set on a computer using a special program, which then generates signals to control the movement of the table. The proposed complex implements a set of various postural loads, neuropsychophysiological technologies and rehabilitation measures, carried out thanks to the presence of a movable table of the subject (patient) in three-dimensional space and program-controlled postural influence. The magnitude of the loads created by these influences is determined by the angles of inclination and the speed of movement, the duration of a person’s stay in a particular position, and the frequency movements. Loads and discrete recording of physiological parameters depend on the specific purpose of the study. Based on the created system, it is possible to implement technologies for personalized external influence, professional selection and condition forecasting in the process of activity in various conditions, including extreme ones. The developed complex can be used in medical, rehabilitation, training and sports centers.
