Modern treatment of foot deformities made it possible to increase the positivity of the outcomes of their surgical treatment. Surgical correction of anatomical distortions significantly improves the supporting and motor functions of the foot. To achieve this goal are widely used in various corrective interventions on the anterior section of the foot. The abundance of methods for these operations indicates that there are no optimal standards to date. The influence of bone and articular changes to locomotion and dynamics of movements of the lower extremities remains largely unexplored. Expanding the diagnosis of dynamic changes in the gait cycle as a result of deformity of the forefoot can help optimize the choice of correction method. This will give the potential to determine the indications for a particular method of restoring the correctness of anatomical relationships. Therefore, diagnostics of the transformation of the gait cycle with deformations of the forefoot is of undoubted interest. The purpose of the study is to evaluate the biomechanical features of movement of a person with anterior foot deformity, pain syndrome caused by deformity, and to explain the influence of the deformed foot shape on the change of individual phases of the gait cycle. To find out the changes in the walking function, we used a three-dimensional video analysis method. The main group was represented by 29 patients with anterior deformity of feet. The research was organized in 2018-2020. The average age was 51.3±16.5 years (from 20 to 80 years female patients were 29 (96.7%)). The control group consisted of 22 healthy women without foot deformities, with an average age of 45.4±15.5 years. The tool base of the research was the Vicon motion capture system (digital infrared cameras Vicon T40-10 PCs., video cameras Vicon bonita 720-2 PCs., dynamometer platform AMTI – 2 PCs., software Vicon Nexus, Vicon Polygon). The study used a full Body Plugin Gate (URM-FRM) skeletal model consisting of 39 reflective markers arranged in a certain order on the human body. The analysis of kinematic data revealed that all 29 studied patients had violations of biomechanics of movements in the joints of the lower extremities. There was an increase in the time of double support by 22.2% from 0.21±0.057 s for the control group to 0.27±0.064 s for the main group. Video analysis allowed us to combine the data obtained using computer graphical visualization of movements with the indicators of the support reaction force and the speed of movement of the lower extremities in patients with foot deformities, as well as to reveal the internal architecture of the gait cycle.
Modern and perspective tasks of robotics with control from artificial intelligence systems require the use of small-sized measuring devices. In this case, the intensively developed quantum sensors and quantum computers have a bright prospect. Their main advantage is the ability to successfully process the data of random processes with decomposition of complex functions into simple multipliers, as well as their small size and the ability to transmit data over long distances without wires. Data transmitted over quantum communication lines cannot be copied or intercepted, which is very useful for remote control of complex technical systems. Based on the results of the analysis of probabilistic noisy data quantum computer is able to quickly develop an assessment of the technical condition of the complex system. At the same time, there is no need to go through all the possible solutions to the evaluation problem with a huge amount of input data, some of which can sometimes be undefined. The main problem in the research of quantum processes is that researchers study the processes occurring in materials, but they do not indicate the ways in which quantum sensors and quantum computers are used in practical applications. This article explains how to form a measuring transformer that will be compatible with a quantum computer. The main objective of the study was to bring the results of basic research in the field of quantum computing closer to their application in applied tasks. It is shown how quantum processes can be shifted to the field of technical measurements of physical quantities used in complex systems. In the process of obtaining the results of the study, the hypothetical deductive method and the method of ascent from the abstract to the concrete within the framework of a systematic approach to the development of elements of technical systems were used. The result is a description of the processes of designing of tension sensing element made of modified diamond. The main findings of the study include the fact that quantum sensors implemented in the form of a modified diamond crystal are well described by the theory of measuring transducers with frequency output and can be used to get data about the state of an object.
