INFORMATION TECHNOLOGY FOR REMOTE MOTOR REHABILITATION
The information technology (IT) for remote motor rehabilitation of patients has been developed. The technology is based on a quantitative comparison of kinematic parameters for the doctor- instructor's movement and patient's one coming from the web-cameras. The training and repeatable video streams are subjected to intra and inter-frame processing. Such procedures as image background subtraction, figure binarization , skeletonization and specific points of the figure searching are executed in the process of intra-frame processing. Coordinate vector of characteristic points of the figure comes to inter-frame processing. When inter-frame processing The matrix of the human body motion kinematic parameters: the trajectories , the tangential velocities and accelerations of characteristic points is constructed . The measures of the difference are calculated to quantify the differences in training and repetitive movements. The Chebyshev's difference measure is calculated for the coordinates of feature points and the cosine measure is calculated for tangential velocities and accelerations. If the difference between these measures do not exceed the thresholds established experimentally, the movement is considered as right if the difference between these measures do not exceed the experimentally established thresholds . Otherwise the instructions for correction of patient movements are automatically generated and transmitted to one. IT is focused on the use of economical computers with free software for availability of a wide range of consumers. IT is implemented practically in a client-server architecture. Since the resource-intensive operations are performed for the video stream processing it is organized in powerful remote server. IT is implemented as a remote system prototype motor rehabilitation. Prototype testing has shown the correctness of the basic principles of the IT. The system provides the right corrective recommendations in real-time. Prospects for further research is to improve the IT opportunities for multi-user access to the system with a variety of devices - tablets, phablet, phones.
