The Methodology for Assessing the Individual Norm in the Diagnosis of the Musculoskeletal System

The article proposes a methodology for assessing the individual norm of functioning of the musculoskeletal system based on goniometric control data, which will improve the accuracy and efficiency of the diagnosis of the musculoskeletal system. During the diagnosis of the musculoskeletal system the evaluation of an individual norm involves a temporary analysis of the dynamics of the range of motion of a particular patient and the identification of pathological changes against the background of an individual norm. According to the methodology, it is proposed to evaluate the individual rate of movement when registering the movement parameters with personalized wearable systems based on displacement sensors (accelerometers, gyroscopes). Sensors record the dynamics of the parameters of the movement of the elements of the musculoskeletal system in the process of everyday physical activity. The resulting time series are scaled by time, filtering and subsequent classification of movements according to their angular parameters. An individual patient model is formed on the basis of a basic model, which contains general norms of permissible deviations of controlled parameters. The applied processing algorithms are based on neural networks. For practical verification of the developed methodology, from September 2019 to March 2020, measurements were made of the mobility of the knee joint in 10 students. As can be seen from the results obtained, each observed student can be distinguished by their parameters of flexion of the knee joint, as well as the individual style of flexion during the day. Despite the described shortcomings of the introduction and testing of the proposed methodology, the results obtained during the study indicate the possibility of applying the developed methodology and the need for its further development.
