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 organizatio

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
12、 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)

17、e 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
18、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 ena
19、ble 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.

When appropriate, the magnitude of the abnormality which is considered to be significant is noted.Any abnormality in the timing of the gait p
