Gait analysis is used to assess, plan, and treat individuals with conditions affecting their ability to walk. It is also commonly used in sports biomechanics to help athletes run more efficiently and to identify posture-related or movement-related problems in people with injuries.
'See-Gait' is an innovative and affordable 3D motion capture system for gait analysis, it is designed for use with a treadmill and can work up to jogging speeds. It could be adapted for use in bicycle fitting and analysis.
There are 4 stages to the process
Cameras are placed each side of the subject and capture the 3D co-ordinate of each marker position.
During the capture sequence the actual joint angles are calculated and displayed on a graph in real time and all the data is saved to file for off line analysis.
An example of some of the extracted data is listed below -
At the end of the capture sequence a moving 3D model is produced that can be viewed from any angle
Drag the mouse or swipe the scene below to view the short sequence from different angles
The stored data can be analysed using various tools, an example of which can ve viewed in the short video below showing the trajectories of each marker.
