A prosthetic foot is the component of a lower limb prosthesis that contacts the ground and transfers load during walking. Different foot groups may be considered in line with the person's activity level, intended use and the physician's assessment.
Foot component groups
Prosthetic feet are generally grouped according to their structural features:
- Solid ankle (SACH) feet: Designs considered for basic-level use.
- Articulated feet: Designs that allow ankle movement.
- Carbon-based (energy-returning) feet: Lightweight designs considered for active use profiles; their working principle is covered in detail on the dynamic carbon-fiber foot page.
Which group is suitable varies from person to person and is determined by the specialist physician's assessment.
Factors that play a role in selection
In selecting a foot component, the level of limb loss, the person's daily activity level, body weight and goals of use are assessed together. The guide to prosthetic foot components, which compiles the selection criteria and working principles, and the article general information about prosthetic feet, which explains the function of foot designs, complement this assessment. This assessment is part of the prescription/medical report process.
