Among the elderly and patients with mild brain diseases (such as dementia and stroke), when there is a certain degree of self-acting ability and cognitive ability, exercise and cognitive rehabilitation are often required. However, since most of the existing rehabilitation systems are separated or specialized in exercise or cognitive rehabilitation, there is a need for a form linking both. In this paper, we propose a game-type rehabilitation system that enables both exercise and cognitive rehabilitation using CAN communication protocol, one of ICT technologies. This system uses the CAN BUS structure to separate and combine each individual module constituting the rehabilitation system in various forms. A prototype of the proposed system was actually produced to show that various types of rehabilitation environments can be implemented according to the degree of cognitive ability and motor ability of the patient (or the elderly). In addition, through several experiments using this system, it is possible to implement exercise/cognitive parallel rehabilitation applicable to various environments.

지역사회에서는 병원퇴원 후 경증장애인의 체력회복을 도와 일상생활로의 복귀를 지원하고 노인 등 취약계층의 건강유지 및 증진을 위한 저비용 개인맞춤형 재활운동 서비스 시스템이 요구된다. 특히, 병원과의 데이터 연계를 통해 개인의 건강상태, 질병에 따라 최적화된 재활운동이 관리될 경우, 효율적인 재활 및 2차 부상방지를 지원할 수 있다. 이에, 본 연구에서는 재활운동의 비용감소와 장애인 및 노인 등 취약계층의 운동재활 접근성(코칭/시설) 강화를 위한 O2O(Online-to-Offline) 연계 AI 기반 개인맞춤형 운동재활 서비스 시스템을 설계한다.

본 논문에서는 뇌졸중 환자의 독립적인 재활운동이 가능할 수 있는 시스템을 제안한다. 뇌졸중은 뇌기능의 부분적 또는 전체적으로 급속히 발생한 장애가 상당 기간 이상 지속되는 상태를 의미한다. 이러한 뇌졸중은 상지 운동을 통해 대뇌 운동피질을 활성화하여 재활 할 수 있어, 의학 분야에서는 운동기구를 이용하여 뇌졸중 환자의 재활을 돕고 있다. 하지만 병원이 아닌 가정에서 운동을 하기에는 운동기구에 비용, 작업치료사의 부재와 같은 환경적인 측면으로 무리가 있다. 따라서 본 논문에서는 가정에서 환자가 독립적인 운동을 할 수 있게 MCU와 Android Application을 이용하여 의료진이 환자의 옆에 없더라도 운동이 가능하고 가이드를 제공하는 스마트한 재활운동기기를 개발하였다. 또한 기존의 재활운동기기는 단순히 운동만 할 수 있었다면, 본 연구에서는 Android Application에서 게임을 제공함으로써 보다 즐겁게 운동이 가능하여 재활의지 증가를 기대해볼 수 있다. 뿐만 아니라 환자의 운동 데이터가 실시간으로 저장되어 병원에서 의료진이 환자의 운동 상태를 파악할 수 있도록 구성함으로 써 향후 뇌졸중 환자의 재활연구분야에 도움이 될 것이라 생각한다.

본 연구는 기존 재활치료전문가의 경험 기반 재활치료 훈련기법에서 진일보하여 보다 객관적인 데이터 기반의 효율적인 재활치료 지원이 가능한 보조시스템을 개발하고자 하였다. 근육의 움직임에 따른 활동전위를 측정하는 근전도와 실제 근육의 움직임에 따른 활동 상태를 가속도 및 자이로센서를 활용하여 측정함으로써 재활치료 시 보다 객관화된 데이터의 축적과 치료계획의 수립이 가능하다. 이를 위하여 본 연구에서는 재활치료 중 근전도 신호와 가속도, 자이로 센서를 결합한 재활운동효과 모니터링 시스템을 구현하였다. 그리고 구현된 시스템의 성능평가를 위해 피실험자 5명을 대상으로 다양한 재활치료 운동방법별 근전도 신호와 가속도 및 자이로센서 신호를 측정 및 분석하였다.

The existing rehabilitation systems were developed to exercise specific joints only. Therefore rehabilitating the various joints of human, various kinds of devices are need. To overcome these defects, this paper proposed the CMRS, an integrated system that performs various rehabilitation exercises. The characteristics of motion and the positions between human body and the system were investigated with the kinematics analysis of upper and lower limb of human body. We presented a proper mechanism to develop a rehabilitation device on the base of the study and studied the relative positions between head part and human joints. Through the simulations, the possibility of rehabilitation system was verified. And the base frame was also developed for convenient and stable position control. Finally, the CMRS was developed as an 8 degree of freedom mechanism. It is expected that the CMRS will be applied to the rehabilitations of various joints.

Our study is to verify validation of exercise effect that developing exercise and rehabilitation instrument using pneumatic actuators available rehabilitation and healthcare, while at the same time safer and more convenient for the user to select the desired exercise. Shares subject to the usual exercise is conducted in less than a week in the knee extension and flexion at the undergraduate level there is no more than 10 of the 20 patients were female. Subject performed knee exercise 3 set a day with 12times a set using fluid type exercise instrument and pneumatic exercise instrument that build in this study. Experiment has progressed in 4-weeks with 3-days a week. Our exercise load consist of two type. One is active exercise load with developed instrument in our study and the other one is passive exercise load with fluid instrument. Exercise program based on real-time muscle activation patterns and muscle activity before and after exercise by comparing the effects of exercise for rehabilitation has been verified. The results showed that muscular activity is higher in active exercise load than passive load, and improvement of muscle strength more increased too. Equipment more user-centered exercise more effectively exercise may enhance muscle strength was found. This study can adapt rehabilitation program and exercise for patient and weaker. Also our system can provide easily and convenient prescription of rehabilitation for expert related rehabilitation.

This paper presents an augmented reality (AR) based rehabilitation exercise system to enhance the motor function of the hands for the paretic/hemi-paretic patient. The existing rehabilitation systems rely on mechanical apparatus for palsy rehabilitation, but we aim to use the rehabilitation system at home with easy configuration and minimized equipment by the computer vision based approach. The proposed method evaluates the interaction status of the fingertip action by using the position and the contact of the fingertip markers. We obtain the 2D positions of the fingertip markers from a single camera, and then transform the 3D positions from the calibrated camera space by using an ARToolKit marker. We adopt simple geometric calculation by the conversion of the 2D interest points into the 3D interaction points for the simple interactive task in AR environment. Some experimental results show that the proposed method is practical and simply applicable to the applications with personal AR interaction.

본 논문은 만성폐쇄성 폐 질환이 흡연, 대기오염으로 많은 질환자가 발생하여 재활운동을 필요로 하는 추세이다. 현재 측정 도구와 재활운동 도구가 분리되어 질환 진단은 한정된 시설을 이용해야만 하고 재활운동 또한 상시 진행할 수 없어 질환을 확인하기 어려운 실정이다. 이에 평상시 착용하는 이너형태에 재활운동 의류를 개발하여 올바른 호흡을 돕는 근육군이 동원하여 복식호흡을 유도하고 흉식호흡 시 웨어러블기기를 통해 인지하게 돕는다. 이 결과 일상 속 지속 가능한 재활운동을 바탕으로 가슴 벽의 호흡근육 활동을 감소시키고 복부 근육군을 개선하는 것으로 폐 기능을 증진시킬수 있는 언더웨어 개발을 제안하고자 한다.

The people who is returning to the community after hospital treatment are faced with the choosing where to proceed with rehabilitation exercise with an appropriate exercise specialists based on the current health condition of them. It is required to supprot a personalized exercise rehabilitation service (hereinafter referred to as ARES system) in the community based on individual disease information and health conditions based on hospital clinical data. In this study, we designed a resource management system for online-to-offline (O2O) based coach matching to improve accessibility with facilities and coaches for exercise rehabilitation in the community.

In this study, the active exercise load control system was developed that monitors patient's muscular condition based on EMG signals and controls the load by biofeedback in real-time. In order to select appropriate muscular parameter for the system, the pre-exercise test was performed to obtain EMG signals from healthy 12 males. Subsequently, the main exercise test was performed to evaluate the active exercise load control system based on IEMG: a selected muscular parameter, on healthy 10 males without musculoskeletal disorder. The accuracy and availability of developed system were confirmed through observing changes between exercise load and IEMG. A correlation was analyzed between the fatigue of muscles and RPE indicating the individual subjective fatigue. As a result, the active exercise load control system that was suggested in this study could be useful to control the initial load-balancing and the amount of exercise appropriate for individual in rehabilitation exercise therapy.
