Introduction

There is no unified term for pathological gait in China:

Different industry and clinical groups in different regions have developed and used their own set of terminology according to their needs:

--- Part 1: Normal gait: The purpose is to define the term for normal human gait:

--- Part 2: Prosthetic gait: The purpose was to define prosthetic gait terms for unilateral lower limb amputees:

--- Part 3: Pathological gait: The purpose was to define the terms of pathological gait in patients who deviate from normal gait:
