Normal Human Locomotion, Part 1

Basic Concepts and Terminology

Abstract

Over the past several decades, the evolution of gait science has produced an array of terms and concepts relating to observational gait analysis. Prosthetists and orthotists use various forms of gait analysis on a daily basis as an important part of clinical care.

When the basic principles of normal walking are understood, a more penetrating grasp of pathological gait becomes possible. The result is expanded ability to differentiate between pathological and compensatory gait deficits. In addition, efficient interaction with the clinic team demands a sound conceptual knowledge base of human locomotion and related terminology. This will facilitate an optimal treatment plan for the patient and enhance communication and prescription recommendations to the physician and relevant paying agencies. This article is intended to be an introduction to gait science with these goals and objectives in mind.
