Methods and technologies for gait analysis

Gait analysis is a highly active research area with a wide range of applications in clinical settings, surveillance and human-computer interaction. The focus of this chapter is the clinical aspect of gait analysis, in which accuracy and precision are essential. Subsequently, the chapter focuses on various techniques of measuring gait and introduces taxonomy for their analysis. From this perspective, motion measurements using motion capture and inertial sensors are presented. Motion capture techniques are analyzed under sections of marker-based and markerless techniques and their common applications are exemplified. Additionally, accelerometers, gyroscopes, magnetometers and their applications are presented in the inertial measurements section. Finally, force measurements and measurement of electrical activity of muscles are explained briefly.
