Full title and description

ISO 29783-1:2008 — Prosthetics and orthotics — Vocabulary — Part 1: Normal gait. This part establishes a standardized vocabulary for describing normal human gait to support clear clinical documentation, research reporting and product specification in the field of prosthetics and orthotics.

Abstract

ISO 29783-1:2008 defines terms and short, precise definitions used to describe the normal gait pattern (gait cycle, stance and swing phases, double support, cadence, step/stride parameters and related concepts). The intent is to provide consistent language for clinicians, researchers and manufacturers when describing gait in healthy (non-pathological, non‑prosthetic) contexts.

Scope

This part of ISO 29783 establishes a vocabulary for the description of normal gait. It is intended for use where a consistent, internationally agreed set of terms and short definitions is needed to describe the timing, phases and commonly reported parameters of normal walking. It does not address pathological gait descriptions or prosthetic‑specific gait; those topics are covered in other parts of the ISO 29783 series.

Key topics and requirements

• Standardized definitions for basic gait concepts: gait cycle, stance phase, swing phase, double support, cadence, step and stride parameters.
• Clear terminology for temporal and spatial gait descriptors used in clinical and research reports (e.g., cadence, step length, stride length, phase timing).
• Short, unambiguous entries focused on normal gait so that comparability across studies, clinics and product specifications is improved.
• Intended interoperability with other parts of the ISO 29783 series that address prosthetic gait and pathological gait.

Typical use and users

Primary users include prosthetists, orthotists, rehabilitation clinicians (physiotherapists, physical medicine specialists), gait laboratory staff, clinical researchers and medical device manufacturers who need consistent terminology for reporting or specifying gait in healthy subjects. National standards committees and technical experts participating in ISO/TC 168 also use this vocabulary when drafting or harmonizing related standards.

Related standards

ISO 29783 is a multipart vocabulary series. Closely related parts include ISO 29783-2:2015 (Prosthetic gait — vocabulary) and ISO 29783-3:2016 (Pathological gait — excluding prosthetic gait). Users will commonly apply Part 1 together with Parts 2 and 3 depending on whether the focus is normal gait, prosthesis‑related gait or pathology‑related deviations. Other related prosthetics/orthotics standards and vocabulary documents are maintained by ISO/TC 168.

Keywords

normal gait; gait cycle; stance phase; swing phase; double support; cadence; step length; stride length; prosthetics and orthotics; vocabulary; ISO 29783.

FAQ

Q: What is this standard?

A: ISO 29783-1:2008 is an ISO international standard that defines a standardized vocabulary for describing normal human gait in the context of prosthetics and orthotics.

Q: What does it cover?

A: It covers concise, agreed definitions of basic gait concepts and temporal/spatial parameters used to describe normal walking (gait cycle, stance/swing phases, double support, cadence, step/stride measures, etc.). It is focused on normal (non‑pathological, non‑prosthetic) gait.

Q: Who typically uses it?

A: Clinicians (prosthetists, orthotists, physiotherapists), gait lab personnel, clinical researchers, medical device manufacturers and standards developers working within ISO/TC 168.

Q: Is it current or superseded?

A: The standard was published in December 2008 (Edition 1) and was confirmed in ISO’s periodic review process; ISO’s catalogue shows it as the published edition and lists later confirmations — it remains the published Part 1 edition as listed by ISO. Users should check ISO or their national standards body for any subsequent amendments or status changes.

Q: Is it part of a series?

A: Yes — ISO 29783 is multipart. Relevant companion parts include ISO 29783-2:2015 (Prosthetic gait) and ISO 29783-3:2016 (Pathological gait, excluding prosthetic gait). Together the parts provide a comprehensive vocabulary for gait description across normal, prosthetic and pathological contexts.

Q: What are the key keywords?

A: Key keywords are normal gait, gait cycle, stance phase, swing phase, double support, cadence, step length, stride length, prosthetics, orthotics, vocabulary.
