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.

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.

This paper investigates the kinematic and dynamic analysis of a spherical three degree of freedom parallel joint module, which is used in the exercise equipment for balance and leg-strength improvement of aged people. The joint module has three dyads which consist of two links and three revolute joints, and their all joints intersect at the global point located at the module's center. The paper shows the explicit mathematical procedure for deriving the closed form solutions in the inverse and forward position analysis of this parallel joint module. In velocity and acceleration analysis, we derived relations for joint velocities and accelerations of dyads and rotational velocity and acceleration of the top plate. For applying this module to rehabilitation exercise, we determined the dynamic model of the Korean males in their 50s and examined the model's results by dynamic model simulation.

In this paper a cervical rehabilitation robot for Mckenzie exercises to be effective to neck pain relief is proposed. The robot has two degrees of freedom (DOF) for Lateral flexion and extension, Dorsal and Vental flexion which enable user to perform cervical stretching and isometric exercises for neck muscles. The mechanical parts of the cervical rehabilitation robot can be mounted on a back- or head-rest of chair, and user can perform the Mckenzie exercise with seated. In experiments we measured the range of motion of cervical part, EMG signals from neck muscles and the contact forces of a head bracket fixing the head part of user, and then evaluated their performances. From the experimental results, we showed a feasibility of the cervical rehabilitation robot proposed in this study.

In this paper, the feasibility of a wheelchair carrier for the disabled own driver is checked kinematically to fit one of current domestic vans by drawings, design. A van with 9 passengers is selected for the modification to attach the wheelchair carrier and test the operation in real situation. The trajectory and motion process are studied to protect from the interception with outside body of van, and the conceptual design is proceeded kinematically. For the detail design, the stress analysis and driving mechanism with power supply must be studied and selected basically.

A The purpose of this study was to determine the present state of the exercise rehabilitation field, promote elderly sport for all, and present a revitalization program for higher quality of life for the elderly in the coming era of the Fourth Industrial Revolution and aged society. Literature review was performed to analyze the actual conditions of the activities for elderly sport for all and the relevant field of exercise rehabilitation, analyze the elderly health and welfare and elderly sport for all programs, and present a plan for revitalizing the field of exercise rehabilitation to promote elderly sport for all. First, it is necessary to reinforce the awareness and promotion of the need and importance of exercise rehabilitation in inducing seniors to participate in sport for all. Second, it is necessary to make it compulsory to place sport leaders for seniors at such places as elderly leisure and welfare centers and promote expertise in managing elderly health guidance efficiently through cooperation with welfare workers. Third, it is necessary to make it compulsory to take exercise rehabilitation and similar subjects in the curriculums of sport for all, elderly sport welfare, and silver welfare sport as well as the subject of volunteering activities at such places as elderly leisure and welfare centers with the aim of giving opportunities for career choice. Fourth, it is necessary to develop characterized exercise rehabilitation programs at senior welfare centers, community centers for the elderly, and elderly classes and employ experts equipped with exercise event and exercise rehabilitation capabilities as itinerant lecturers to contribute to the government's job creation policies through cooperation between the Ministry of Culture, Sports, and Tourism (MOCST) and the Ministry of Health and Welfare (MOHW). Fifth, it is necessary to make a greater investment in research and development required for elderly sport for all. Sixth, it is necessary to develop and distribute various exercise rehabilitation treatment videos and guidelines that seniors can use for themselves. This is associated with the fifth one; in particular, it is urgent to devise measures against Coronavirus 19. Seventh, it is necessary to reduce inefficiency and budget waste caused by overlapped tasks by establishing a new elderly sports promotion organization through adjustment by MOCST and MOHW; it is also necessary to increase the functions of organization establishment with the aim of reinforcing the education area, which involves post-retirement health care, exercise rehabilitation, safety accident prevention, and virus.

In this study, the training and sporting equipment for leg rehabilitation featuring the MR fluids is proposed. The compact MR fluid brake is designed and manufactured to apply to the rehabilitation training and sporting mechanism. The resistance characteristic of the MR fluid brake is controllable by varying the magnetic field around the fluid. Under consideration of spatial limitation, design parameters which are related with the magnetic strength are determined to maximize to a torque using finite element method. The FE analysis is performed using a commercial code, ANSYS Workbench. The proposed brake device is manufactured, and its field-dependant torque is experimentally evaluated. When the electric current is supplied, the torque of the MR fluid brake is increased and the response is very fast. Depending on the strength of the current supply, torques of the MR fluid brake also increase similar to Bingham property of MR fluid.

The purpose of this study is to examine the changes in the elderly healthcare app market through text mining analysis and to present basic data for activating elderly healthcare apps. Data collection was conducted on Naver, Daum, blog web, and cafe. As for the research method, text mining, TF-IDF(Term frequency-inverse document frequency), emotional analysis, and semantic network analysis were conducted using Textom and Ucinet6, which are big data analysis programs. As a result of this study, a total of six categories were finally derived: resolving the healthcare app information gap, convergence healthcare technology, diffusion media, elderly healthcare app industry, social background, and content. In conclusion, in order for elderly healthcare apps to be accepted and utilized by the elderly, they must have a good diffusion infrastructure, and the effectiveness of healthcare apps must be maximized through the active introduction of convergence technology and content development that can be easily used by the elderly.
