Finite Element Simulation of Frontal Plane Adaptation Using Full-Foot, Split-Toe, and Cam-Linkage Designs in Prosthetic Feet

Conclusions

This finite element simulation study shows that a frictionless cam-linkage with frontal plane adaptability integrated into a prosthetic foot improved mediolateral forces, displacement, and frontal plane angular rotation of the proximal pylon compared with a locked linkage during the stance phase of gait when in contact with a 15-degree cross-slope. These findings may have implications for people using lower-limb prostheses if future studies demonstrate improved gait over uneven ground, or reduced pain, skin breakdown, and the work of walking.
