--- Added "gender" and "age" (see Chapter 5);

--- Changed "Move" (see 9.1, 9.1 of the 2014 edition).

This document is equivalent to ISO 29782:2022 "Prosthetics and orthotics — Factors to consider in prescribing lower limb prostheses".

Introduction

The selection of prosthetic components for patients requires consideration of their amputation level, stump and physique, clinical symptoms, functional status, initiative and needs.

The needs, expectations, and socioeconomic environment of the prosthesis also need to be considered, as well as the environment in which the prosthesis is used, local availability, and maintenance.

The other extreme is that the patient wants and can perform strenuous activities and requires a decorative prosthesis.

Some patients need special parts to carry out certain activities. Prosthetic fitting institutions need to use this information to Components are selected based on their knowledge and clinical experience.

Many factors influence the choice of prosthetic components. The goal of prosthetic treatment is to control damage, reduce limitations, and thus improve daily life.

Participation in all aspects of daily living (ADL).

The final outcome depends on personal factors as well as environmental factors (such as relatives), which are collectively called background factors.

Funding for prostheses, the availability and maintenance of prostheses, and the environmental conditions in which they will be used also influence decisions.
