Biomechanics represents a fundamental pillar of biomedical engineering, focusing on how mechanical forces interact with biological systems. This discipline studies the structure, function, and motion of biological systems using principles from mechanics, providing essential insights for designing prosthetics, implants, and rehabilitation devices. An understanding of biomechanics is important when working with amputees and people with prosthetic limbs, as it is especially relevant to understanding how gait deviations and pressure problems occur and how they can be remedied, and is essential for prosthetists as it influences so many aspects of their work during prosthetic rehabilitation.

In prosthetic design, biomechanical principles guide engineers in creating devices that replicate natural movement patterns while distributing forces appropriately across the residual limb. The idea of spreading force over a large enough area to reduce pressure to an acceptable amount is used in prosthetic socket design. This fundamental concept ensures patient comfort and prevents tissue damage during extended use.

Prosthetics are biomedical devices that attempt to best replace lost limbs or organs, and are generally divided into two main groups: exoprostheses, which are located outside the body, and endoprosthetics (implants), which are placed directly inside the body. The biomechanical considerations for each type differ significantly, requiring specialized engineering approaches.

Exoprostheses combine the knowledge and experience of many advanced technology fields such as biomechanical engineering, material science, bionic systems, electronic circuits and computer-controlled technologies.
