INFORMATION TECHNOLOGY FOR EFFICIENT RECOVERY/CORRECTION OF MUSCLE ACTIVITIES FOR MOTOR TASK PERFORMANCE
Introduction. The conditions of wartime and post-war state call for priority requirements for development and utilisation of new information technologies for recovery/correction of motor functions. The major ones are personalisation, mobility, efficiency, ease of implementations both for in- and out-patients.
The purpose of the paper is to consider the theoretical and practical foundations of synthesis of the muscle activity recovery/correction technology for the performance of a motor task with the limbs using a digital-analog device of programmed myoelectric stimulation “MioAktyvSyntez-4”.
Results. The theoretical and practical foundations of synthesis of the information technology, which satisfies the main requirements – personalization, efficiency, mobility, ease of use both in clinical and non-clinical conditions, for recovery/correction of muscle activity to perform a motor task by limbs are developed. The technology is implemented by a new class of digital-analog multi-channel programmed stimulators – four-channel programmed electromyostimulator “MioAktyvSyntez-4”. The device is designed to perform a certain task by movements of limbs’, as well as fine motor skills of the hand to recover the oral speech.
The structural and functional model of the electromyostimulator “MioAktyvSyntez-4” is considered. The main functional units of the device are given and their implementation is determined: unit for selecting the stimulation channels and unit for synthesis of stimulation programs are digital, and the stimulation unit and user interface unit are analog. The use of programmable logic is chosen for processing the information in digital form. The basis of certain algorithm for selecting the stimulation channels for forming the stimulation programs – the truth tables are considered. The structural and functional scheme of the technical implementation of formation of limbs’ movements with the digital-analog device “MioAktyvSyntez-4” is considered.
Conclusion. Further research is aimed at retrofitting the “MioAktyvSyntez-4” type devices with modern interfaces, means of control and diagnostics in order to improve ease of utilisation and efficiency of personalised recovery/correction of the movement of the limbs. This is of paramount importance after military and civilian injuries, in adults and children, during the wartime and in post-war state.
