The patients who have illness of hand and upper limb should be received rehabilitation treatment to recover such illness. The rehabilitation treatments is a treatments designed to facilitate the process of recovery from injury, illness, or disease to as normal a condition as possible. This should be done continuously and repeatedly. In this paper, we describe hand-rehabilitation system which provides a treatment method improving and recovering the function of injured hands. Expecially, this system is using a leap motion device which can easily and properly identify and trace a hand motion and provide six treatment patterns for hand rehabilitation. By using this system, the patients can do rehabilitation treatment easily and continuously in their daily life and in result, the achievement of treatment will be improved.

최근 고령화 사회로 인해 전 세계적으로 노년층 인구수가 증가하고 있다. 하지만, 노인들의 신체 능력은 더욱 약화되고 있으며 병원을 찾아가 진료 및 재활을 받는 것은 신체적으로 부담이 갈 것은 자명한 사실이다. 또한, 재활 치료는 본인이 느끼는 것에 따라 진단 결과가 나오며 의사 또한 정확한 수치를 확인할 수 없어 제대로 된 진단 결과를 받을 수 없다는 문제가 있다. 본 논문은 이러한 문제를 해결하기 위해 병원을 직접 찾아가지 않고, 자택에서 측정 및 재활이 가능한 시스템을 제안한다. 재활 치료를 받는 환자의 신체정보를 근전도 센서, 심박 수 센서 등을 활용하여 상시 체크를 하고 의사가 실시간으로 모니터링을 하며 환자의 상태를 확인 및 상담과 조치를 취할 수 있는 시스템을 만들어 최근 증가하고 있는 노년층들이 신체적, 금전적 제약을 받지 않고 진료 받을 수 있게 할 것이다.

The objective of this paper is to develop the motion recognition method for the rehabilitation program of the people with physical disabilities. Using the infrared ray LED, this method gets the information of the user's motion and tells the difference between the information we get and the pre-defined information. In order to get the fast recognition and comparison, this method positions the specific coordinates of infrared ray LED in the pre-classified sector which keeps certain distance and angle from the point of origin. The result in our experiment shows the speed over 20 frames per second in every motion, and we are satisfied the rate for the recognition of the motions which is near 98%.

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.

재활 및 의료기기에 적용되는 핵심적인 설계요소와 제어기술을 소개한다. 노약자를 다루는 시스템에서는 미세한 부분까지 고려해야 하며 안전을 담보로 하고 제어기 설계는 아주 보수적인 방법이 요구된다. 특히 환자를 대상으로 하는 경우 환자의 의지를 반영하여야 하고 메커니즘은 특수한 경우에도 문제가 발생하지 않을 정도로 안정성을 고려한 설계가 이루어져야 한다. 이 글에서는 재활 및 노약자를 대상으로 하는 다양한 메커니즘과 제어기술을 소개하고 정보기술과의 접목이 이루어지는 재활 및 의료기기의 최신 기술에 대한 정보를 제공한다.

Objective: To develop and verify the usability of a cognitive rehabilitation system with diverse cognitive functional levels based on tangible objects for the elderly population. Methods: A study was conducted to investigate the system's strengths and weaknesses by upgrading it with responses from two groups of 15 patients and 4 occupational therapists. After undergoing three forms of training - regarding executive function, memory, and concentration for a total of 20-30 min, the participants were asked to answer a structured questionnaire about contents of the three forms of training, hardware including the tablet PC functioning as a CPU and display media and tangible objects, and satisfaction of experiential usage of the system. Results: Both groups responded that the most interesting training area was executive function while the least interesting was concentration. Six participants reported that the size of the screen of the tablet PC was inappropriate, and five responded that the size of the tool was inappropriate. All therapists and 40% of the patients responded that they were satisfied with this system. Conclusion: This system's features include easy manipulation of tangible tools for performing training tasks, easy selection of and training in cognitive areas based on users' needs, and automatic adjustment of difficulty level based on users' performance. The training environment was designed to be similar to the natural environment by using tangible objects in both hands as input devices for the system, and the system was considered as an alternative to the lack of community cognitive rehabilitation specialists.

When the eldery with limited mobility and disabled use a wheelchairs to move, it can cause decreased exercise ability like decline muscular strength in upper limb and lower extremities. The disabled people suffers with spinal cord injuries or post stroke hemiplegia are easily exposed to secondary problems due to limited mobility. In this paper, We designed intelligent wheelchair robot system for upper limb and lower extremities exercise/rehabilitation considering the characteristics of these severely disabled person. The system consists of an electric wheelchair, biometrics module for Identification characteristics of users, upper limb and lower extremities rehabilitation. In this paper, describes the design and configurations and of developed robot. Also, In order to verify the system function, conduct performance evaluation targeting non-disabled about risk context analysis with biomedical signal change and upper limb and lower extremities rehabilitation over wheelchair robot move. Consequently, it indicate sufficient tracking performance for rehabilitation as at about 86.7% average accuracy for risk context analysis and upper limb angle of 2.5 and lower extremities angle of 2.3 degrees maximum error range of joint angle.
