  1. Biomechanical analysis for knee joint during vertical free landing Advisor ：S.W Yang Reporter： J.S Guo

  2. Introduction

  3. Vertical landing • Knee permits large range of motion of flexion & extension • Most of landing reaction force is absorbed by knee

  4. Purpose • To predict that the muscle & ligament force distribution and orientation during activity can protect or prevent the injure

  5. Material & Method

  6. Flow chart Motion data anthropometry Joint force & moment Muscle & ligament properties Ground reaction force attachment & trajectory & orientation & PCSA Inverse dynamics Human database validation optimization Muscle & ligament force EMG

  7. Human database Segment mass& inertial moment anthropometry Muscle properties Anatomy & reference Ligament properties Anatomy & reference

  8. Motion analysis Motion capture VICON Ground reaction force Force plate Calculate knee Joint force Polygon (custom software)

  9. Optimization CE: muscle fibers PEE: connective tissue SEE: tendon Muscle & ligament modeling Objective function Based on muscle activation (1 or 0) & find the least muscle force constranits Limitations for muscle & ligament Force

  10. Thanks for attention
