#49 Design Considerations: Prosthetic Knee | Mechanics of Human Movement

Welcome to 'Mechanics of Human Movement' course ! This lecture focuses on design considerations for prosthetic knees: Key Requirements for Prosthetic Knees: Discuss the key requirements for prosthetic knees, focusing on: Stability in Stance: Emphasize the importance of preventing knee buckling during weight-bearing. Swing Control: Explain the need for controlling knee motion during swing to achieve proper foot clearance and prepare for the next step. Shock Absorption: Discuss the incorporation of shock absorption mechanisms in prosthetic knees to reduce impact forces. Geometric Stability and Knee Center Location: Explain how the location of the knee center with respect to the load line influences knee stability, introducing the concept of geometric stability. Single-Axis vs. Polycentric Knees: Compare single-axis and polycentric knees, highlighting the advantages of polycentric knees in achieving a more natural gait pattern and reducing energy expenditure. Four-Bar Linkage in Polycentric Knees: Explain how a four-bar linkage can be used to create a polycentric knee, allowing the knee center to shift during flexion and extension. Benefits of Polycentric Knees: Discuss the benefits of polycentric knees, including improved toe clearance during swing and the ability to achieve a more natural gait pattern.
