Abstract:
Gait analysis based on video cameras and the instrumented treadmill is an inexpensive, convenient,
and efficient manner of providing useful information for multiple health-related applications. As
a clinical tool applied in the rehabilitation and diagnosis of medical conditions and sport activities,
gait analysis shows great prospects. The techniques of digital video and digital image processing
such as template matching, sub-pixel, motion estimate, etc., are employed to identify and trace the
markers. The current paper reviews available techniques for gait analysis methods. After an
introduction of the gait phases, the principles and features of gait cycles used in gait analysis are
provided. The gait analysis methods are divided into gait kinematics, gait kinetics, and
electromyography. Studies on the current methods are reviewed, and applications in sports,
rehabilitation, and clinical diagnosis are summarized separately. With the development of sensor
technology and the analysis method, gait analysis is expected to play an increasingly important
role in clinical applications
