In the modern age, it is important for people to maintain a good sitting posture because they spend long hours sitting. Posture correction treatment requires a great deal of time and expenses with continuous observation by a specialist. Therefore, there is a need for a system with which users can judge and correct their postures on their own. In this study, we collected users' postures and judged whether they are normal or abnormal. To obtain a user's posture, we propose a four-joint motion capture system that uses inertial sensors. The system collects the subject's postures, and features are extracted from the collected data to build a database. The data in the DB are classified into normal and abnormal postures after posture learning using the K-means clustering algorithm. An experiment was performed to classify the posture from the joints' rotation angles and positions; the normal posture judgment reached a success rate of 99.79%. This result suggests that the features of the four joints can be used to judge and help correct a user's posture through application to a spinal disease prevention system in the future.

본 논문은 한국에서 야구에 관련 직무에 종사하는 사람 또는 야구를 배우고 싶은 사람에게 도움을 주고자 Kinect의 모션 인식 센서를 이용하여 자세인식에 관련 된 연구 내용이다. 야구를 배우고자 하는 사람들에게 자세에 대한 교정과 자신이 직접 자신의 자세를 보면서 활용할 수 있도록 하는 것이 궁극적 목표이며 프로그램의 제작자의 개입이 없이 사용자가 주제가 될 수 있도록 한다. Kinect에서의 야구 자세를 저장하여 자신의 모습과 비교하여 자세에 대한 피드백을 받을 수 있다. 이 프로그램을 통해 사람들이 좀 더 야구에 대해 쉽게 접근하고 이용할 수 있음이 프로그램의 구현 방향이며 야구를 접하는 사람들에게 자세 부분에 도움을 주고 야구를 즐기는 사람들도 도움을 얻는 기대효과를 가지는 프로그램이다.

This study investigated the effects of corrective exercise and TECAR on cervical alignment, pain threshold, and pain in forward head posture patients. The subject includes 30 forward head posture patients. In the intervention methods, the experimental group combined corrective exercise and TECAR treatment. Only the corrective exercise was applied to the control group. Assessments were made on cervico vertebra angle (CV angle), pain pressure threshold (PPT) and neck disability index (NDI) visual analog scale (VAS). The intervention was conducted six times a week for two weeks. Both groups showed significant differences in CV angle, PPT, NDI, and VAS. Also, PPT, NDI, and VAS excluding CV angle were significantly improved in the study group compared to the control group. These results suggest that the intervention method that combines corrective exercise and TECAR treatment has a more positive effect on pain and ADL ability of forward head posture patient.

In these day, the number of people who have an abnormal posture caused by bad habit are increasing. Therefore, people suffer various disease and symptoms. For correcting the posture to cure, we need continuous monitor, expenditure of time and money. In this study, we develop a posture correcting aid system in other to monitor a posture continuously and leads to pose correctly and records postural variation which are attached to the neck and the waist. The devised system showed good potential for the correct posture guide and a cure of postural defect.

With the increase in the number of ICT industry workers, there is a demand for research on preventing VDT syndrome. However, existing posture correction products mostly rely heavily on cameras or sensors in wearable devices. In this paper, we have developed a posture correction system that utilizes built-in cameras and circular pressure sensors to collect posture information. Additionally, the system provides a personalized service by capturing the correct posture of the user initially and monitoring the user's posture based on that input. By precisely correcting postures during users' daily tasks, this system aims to prevent and improve VDT syndrome, ultimately enhancing the efficiency of ICT industry workers.

In this paper, we were implemented the application to induce correct posture by recognizing the incorrect posture of the user. Implemented system uses kinect sensors to determine the user's position information, it has been developed posture determination algorithm that can determine the four wrong posture and correct posture. In addition to PC in order to improve the user convenience and accessibility, to implement real-time monitoring application that can determine the user's position in the smartphone. For the system of performance evaluation of and promote the attitude determination experiment to target the five college students, the experimental results sensitivity and specificity of it it was found that the attitude determination performance is excellent at 0.956.

Physical activities are decreasing and sitting time is increasing due to the automation, smartization, and intelligence of necessary household items throughout daily life. Recent healthcare studies have reported that the likelihood of obesity, diabetes, cardiovascular disease, and early death increases in proportion to sitting time. In this paper, we develop a sitting posture correction cushion in real time using capacitive pressure sensor based on conductive textile. It develops a pressure sensor using conductive textile, a key component of the posture correction cushion, and develops a low power-based pressure measurement circuit. It provides a function to transmit sensor values measured in real time to smartphones using BLE short-range wireless communication on the posture correction cushion, and develops a mobile application to check the condition of the sitting posture through these sensor values. In the mobile app, you can visualize your sitting posture and check it in real time, and if you keep it in the wrong posture for a certain period of time, you can notify it through an alarm. In addition, it is possible to visualize the sitting time and posture accuracy in a graph. Through the correction cushion in this paper, we experiment with how effective it is to correct the user's posture by recognizing the user's sitting posture, and present differentiation and excellence compared to other product.

The aim of this study was to investigate the short-term effects of combined postural correction exercises (CPCE) on muscle stiffness and muscle activity in children with cerebral spastic diplegia(CSD). The subjects were 3 children (2 male and 1 female) with CSD from 4 to 7 years old. The measurement sites were upper trapezius muscle(UT), rectus abdominis muscle(RA), and gluteus maximus muscle(Gmax), muscle stiffness and muscle activity were measured using Myoton and surface EMG, and the symmetry of both sides was also examined. As a result, children with severe compensatory action showed decreased muscle stiffness and muscle activity in UT and RA and increase in Gmax after CPCE intervention. Especially, the left and right symmetry of the muscles was decreased. In this study, despite some limitations, CPCE have shown a positive effect in posture correction of children with CSD.
