Three-dimensional instrumented gait analysis (3D-IGA) is an evaluation approach used to provide a comprehensive assessment and analysis of typical and atypical walking. 3D-IGA provides detailed information on three-dimensional kinematics (spatiotemporal parameters, joint positions, and motions), and often kinetics (joint forces, moments, and powers) and muscle activation patterns (electromyography). 3D-IGA is used to identify specific gait deviations, analyze how specific gait deviations influence function, guide decision-making about intervention strategies, and evaluate treatment outcomes.
This CPG discusses how 3D-IGA can inform surgical and non-surgical decision-making and interventions, identify and analyze gait deviations, and evaluate the effectiveness of interventions. It also provides guidance for clinicians about the preferred characteristics of laboratories including instrumentation, staffing, and reporting practices.
