Human joints are mechanically redundant systems consisting of multiple ligaments and muscles. We have developed musculoskeletal dynamics models of the knee and foot joints and have run simulations to estimate muscle forces, ligament tensions and articular contact forces during daily activities, which helps understand the mechanism of joint injuries.
Walking is a result of complex process that involves neuronal control of muscles, musculoskeletal dynamics and interaction with environments. We investigate the neuronal controller of human walking using the deep reinforcement learning for the applications in orthopaedics, rehabilitation, and sports. Human gait study is closely related with bipedal robots and exoskeleton robots assisting walking.
Unusual movements of the human joint can initiate a degenerative process by changing the mechanical stresses in soft tissues and bone surfaces. We have developed a dual X-ray fluoroscopic imaging system to measure the patient's accurate three-dimensional joint motion. We use this system to understand abnormal joint movements and changes due to surgical intervention.
본 연구실에서는 인체 근골격 운동의 원리와 정형외과적 근골격 문제의 원인을 이해하기 위한 연구를 진행합니다. 다물체 동역학에 기반한 인체 근골격 동역학 모델을 개발하고, 역동역학 해석을 이용하여 근육힘 및 관절 접촉힘을 예측하고 관절 부상 원리를 연구합니다. 최신 AI 강화학습 기술과 근골격 순동역학 시뮬레이션 기술을 이용하여 인체가 다양한 환경에서 걸을 수 있게 근육을 조정하는 인체 뇌신경시스템의 원리를 연구합니다. 관절을 이루는 골격들이 상호 운동하는 형상을 정밀하게 측정하는 엑스선 영상 기술을 개발하고, 이를 이용한 최적의 인공관절 및 관절 수술 기구물의 형상을 연구합니다.
