Objective: Using a 3-degree-of-freedom (DOF) prosthetic foot with lateral and toe joint compliance, this study aims to evaluate the combined effects these features in prosthetic gait through gait trials on 10 non-amputated individual. Results: The addition of coronal and toe compliance had significant kinematic and muscular effects. Notably, this compliance combination reduced peak pelvis obliquity by 27%, preserved the swing stance/ratio, and decreased gluteus medius’s activation by 34% on the non prosthetic side, compared to the laterally rigid version of the prosthesis without toe compliance. Conclusions: The results underscore the importance of integrating coronal and toe compliance in prosthetic feet designs as they shows potential in improving gait metrics related to mediolateral movements and balance, while also decreasing muscle activation. Still, these findings remain to be validated in people with transtibial amputations.
