Gait Analysis
A systematic evaluation of a patient's walking pattern, using observational or instrumented methods to identify biomechanical deviations and inform rehabilitation planning.
Full Definition
Gait analysis is a clinical and biomechanical assessment technique used in physical medicine and rehabilitation to quantify and characterise a patient's walking pattern. It can range from observational gait assessment conducted by a physiotherapist to full instrumented analysis using motion-capture technology, force plates, and electromyography. In rehabilitation reports, gait analysis findings are used to prescribe orthoses, guide surgical planning, or evaluate treatment outcomes. Editors should note that 'gait' refers specifically to the mechanics and pattern of locomotion, and should not be conflated with the broader concept of ambulation (the functional task of walking).
Usage
Usage note: Distinguish between observational gait analysis (clinical, non-instrumented) and instrumented gait analysis (laboratory-based). Documents should specify which method was used to avoid ambiguity.
