Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction
No internationally accepted vocabulary of terms is available to describe the gait patterns of persons
who have had a unilateral lower limb amputation.
As a consequence the members of the different professions and the clinic teams in different countries
have developed and adopted their own terminology to meet their own needs.
This part of ISO 29783 provides a terminology for the description of the gait of persons who have had a
unilateral lower limb amputation by identifying the departures from the normal pattern of gait which
they exhibit. This is achieved by reference to the sub- phase of the gait cycle in which they occur and the
nature of the abnormality.
It will enable practitioners to systematically describe the gait of the persons for whom they are providing
prosthetic treatment and facilitate comparisons with the experience of other practitioners.
