Biomechanical research dictates decisions for improving prosthetic legs by specifying the physical and human movement parameters necessary to manufacture tools that boost natural motion. Understanding the different forces, muscle constraints, joint dynamics, and movements of walking are central to inventors so that they can create prosthesis that closely resembles conventional motion, ensures users' safety, and enhances their overall comfort. The biomechanics assessments promote material selection, joint innovation, and control technologies. It also emphasizes the need to ensure prosthetic limbs effectively interact with the surrounding and allow rapid responses to routine activities. Enhancing prosthetics according to these recommendations will offer improved user mobility, minimize pressure on remaining limbs, foster autonomy, and support a higher life quality.

IMO, biomechanics plays a significant role in design of prosthetic limbs, for the following reason:

The CoP patterns generated in the foot are imprinted within the hip joint. For example, if you client was born with a PreClinical Clubfoot Deformity, the medial displacement of the foot's CoP pattern will be seen as a medial displacement of the CoP pattern within the acetabulum. I found that placing the appropriate insole underneath the prosthetic limb provided stability and comfort, lacking without the insole.
