Abstract Summary
Musculoskeletal models of a person with a unilateral transtibial amputation were developed to investigate hip joint contact force (HJCF) during running using running-specific and daily-use prostheses. Peak HJCF was greater in the intact leg compared to the amputated leg for both types of prostheses. The HJCF was greater in the amputated leg when wearing daily-use prostheses compared to running-specific prostheses. Reducing HJCF magnitude and improving symmetry may be an important target for maintaining long-term joint health.
