In general, dizziness is caused by various situations, but among them, symptoms due to dysfunction of the motor system belonging to the nervous system are the most severe, accompanied by nausea and vomiting. Treatment of these dizziness includes drug therapy, surgical therapy, and rehabilitation. Drug therapy and surgery are generally performed in vest rehabilitation training, which is a rehabilitation therapy because of the risk of aftereffects. The vestibular rehabilitation training includes eye training, posture stabilization training, and walking training. Among them, walking training is performed in a certain space under the supervision of a doctor or a professional therapist, so that the time and space burden is increased. In order to solve this problem, we implemented gait training contents which can be used for rehabilitation training by using the augmented reality technology. It is expected that it can be utilized as dizziness rehabilitative contents which can be used in medical environment through clinical tests for patients with dizziness.

본 연구는 가정용 게임기를 이용한 재활 운동을 적용하여 뇌졸중 장애인의 보행능력에 효과가 있는 가를 알아보고자 하였다. 뇌졸중으로 6개월 이상 장애를 가진 32명이 연구에 참여하였고 게임운동군 16명과 대조군 16명으로 나누었다. 게임운동군은 가정용 게임기(PS2, sony)를 이용하여 1시간씩 주 3회, 6주간 실시하였다. 대조군은 운동의 적용 없이 평상시 생활을 유지하도록 하였다. 운동 전과 후에 보행능력을 측정하여 효과를 비교하였다. 통계처리 방법으로 전 후 차이를 검증하기 위하여 대응표본 t 검정을 실시하였고 대조군과의 차이 검증을 위하여 독립표본 t 검정을 실시하였다. 모든 통계적 유의 수준은 0.05로 하였다. 본 연구의 결과 보행능력에서 10m 보행속도가 유의하게 증가하였고(p<.05), 6분 보행거리도 유의하게 증가하였다(p<.05). 결론적으로 가정용 게임기를 이용한 재활운동이 뇌졸중 장애인의 보행능력에 효과가 있는 것으로 나타났다. 향후 뇌졸중 장애인에게 흥미를 유발하고 기능회복의 효과를 가진 게임형태의 재활운동이 다양하게 개발되어 적용하는 연구가 필요하다고 생각한다.

In this study, electromyography was obtained in the six muscle areas that move the joints of the two legs, and by analyzing it, an exercise robot system capable of gait rehabilitation was proposed in consideration of the individual's muscle state. Through this, the system was constructed to prevent the effect of exercise from decreasing because the patient's will was not reflected when walking exercise was simply provided automatically. As a result of the evaluation of the developed system, it was confirmed that the pedestrian rehabilitation robot system manufactured through this study had performance suitable for the design requirements, and it was also confirmed that the usability evaluation was comprehensively satisfactory. The results of this study are thought to be of great help to patients who are having difficulty in gait rehabilitation, and are believed to be helpful in the development of electromyography signal-based gait robot systems.

본 논문에서는 간병인의 도움없이 자가 보행 재활에 효과적으로 사용될 수 있는 새로운 개념의 가슴 착용형 로봇을 개발하였다. 개발된 로봇의 특징은 크게 세 가지로 나뉜다. 첫째, 구조적 특징으로써, 하박에 착용하는 기존 지팡이 타입의 엘보 크러치와 달리 개발된 로봇은 가슴에 착용되어 착용자의 두 팔을 자유롭게 하는 동시에 팔의 부담을 제거하여 준다. 둘째는 구동 알고리즘의 특징으로써, 가슴부에 부착된 압력센서로부터 사용자의 보행의도를 자동적으로 인식하여 로봇의 다리를 이동시킨다. 또한 착용자의 안전을 위해 초음파 센서를 이용하여 착용자 전방에 장애물이 나타날 시 보행을 멈추고 경고음을 발생시킨다. 마지막으로, 스카치요크 메커니즘을 사용하여 지지다리의 상승과 하강 시 지면 반발력으로 인하여지지 발 상/하강 모터에 과도한 토크가 부과되지 않도록 하였다. 이러한 세 가지 특징으로부터 개발된 로봇이 자가 보행 재활에 효과적으로 사용될 수 있음을 실험적으로 보였으며, EMG (Electromyography) 센서를 이용하여 근력 보조 성능을 정량적으로 검증하였다.

This work proposes a new method to generate velocity profile of a traction motor equipped in a rehabilitation system for knee joint patients through humanoid robot simulation. To this end, a three-dimensional full-body humanoid robot model is newly constructed, and natural human gait is simulated by applying to it reference joint angle trajectories already published. Linear velocity is derived from distance data calculated between the positions of a thigh band and its traction motor at every sampling instance, which is a novel idea of this paper. The projection rule is employed to kinematically describe the humanoid robot because of its high efficiency and accuracy, and measured joint trajectories are used in simulating human natural gait referring to Winter's book. The attained motor velocity profile for a certain position in human body will be applied to our walking-assistance system which is implemented with a treadmill system.

As the population of elderly people and disabled people are increased, various demands for human welfare using robot system are raised. Especially autonomous rehabilitation system using robot could reduce the human effort while maintaining the its intrinsic efficacy. This study deals with mobile gait rehabilitation system which combined with BWS (Body Weight Support) for training of elderly and handicapped people who suffer the muscle force weakness of lower extremity. BWS which is designed by kinematic analysis of body lifting characteristics and walking guide system are integrated with main control system and wheeled platform. This mobile platform is operated by UCS (User Command System) and autonomous trajectory planning algorithm. Finally, through the EMG (Electromyography) signal measuring and its analysis for subject, performance and feasibility of developed system is verified.

In this study, in order to quantitatively confirm walking rehabilitation degree, we analyzed EMG pattern simulated abnormal gait and normal gait by applying a curve fitting. We calculated the suitable high-order function for EMG signal, and classified them into 5 groups by using cluster analysis. Depending on the distance from normal pattern group, we listed the pattern group and then the distribution of each variables were confirmed. The amplitude-decreased pattern was the most similar to the normal pattern, but the reversed pattern showed the lowest similarity. Due to the smaller overlapping range, the distribution of the groups were possible to classify using the value of variable. The standard deviation of each term coefficient was compared to indicate the quantitative rehabilitation extent, and the higher value was confirmed as the pattern is close to the normal pattern. Consequently, the representation of quantitative rehabilitation extent is expected to contribute to the more effective rehabilitation method study.
