  • The purpose of this study is to develop a Multi-joint rehabilitation system (CMRS : C&R Lab. Multi-joint Rehabilitation System). This study presents the mechanism of rehabilitation system that enables rehabilitation of multi-joint with kinematical analysis for joints of human body. Also, the relative positioning between human subjects and the head part to rehabilitate for the mechanism is based on robotics and anatomy. This study was verified with simulations. Finally, Automation of positioning was realized. Rehabilitation exercises in passive mode were enabled with the results.

  • A two-dimensional static biomechanical model of lower extremity in the seated posture was developed to assess muscular activities of lower extremity required for a variety of foot pedal operations. Muscle forces of the model were predicted using the double linear optimization scheme. For the model validation, three subjects performed the experiments which measured EMG activities of six lower extremity muscles. Predicted muscle forces were compared with the corresponding rectified intergrated EMG amplitudes and it showed reasonable results.

  • 일어서는 동작은 일상생활에서 하는 가장 일반적인 행동 중의 하나이며, 다른 동작으로의 전환을 위한 준비자세이기도 하다(Riley PO 등 1991). Corrigan D 등(2001)에 따르면 1987년 65세 이상의 공공시설(병원, 재활시설 등)에서 기거하지 않는 약 2백만 명의 노인이 일어서는 동작에서 어려움을 느낀다고 한다. 또한 무릎의 신근(신전을 담당하는 근육)이 약화된 환자들에게도 앉은 자세에서 일어서는 동작은 무릎에 가장 무리를 주는 동작 중의 하나로 작용한다. (중략)
