Patent Images
1. A gait analysis system for training and rehabilitation purposes, comprising:
- an endless belt guided over at least two rollers and serving as a treadmill belt, wherein the upper surface serves as a walking surface;
a sensor system for determining a pressure/force distribution on a force measurement plate located underneath the walking surface, the force measurement plate having a plurality of pressure/force sensors facing the endless belt;
an analyzing unit connected, on an input side to the pressure/force sensors, the analyzing unit detecting pressure distributions generated on the walking surface by a user'"'"'s feet contacting the endless belt, while the endless belt is in motion, by a subject walking or running on the endless belt;
a processing unit connected to the analyzing unit, the processing unit generating actual pressure distribution images of each footprint of the user'"'"'s feet while contacting the endless belt;
an image display screen arranged in a field of view of the subject;
a film or video reproducer with visual material stored in a visual material storage repository or a connection to connect a visual material database for receiving and displaying the visual material on the display screen as a moving virtual route, and a synchronization stage for synchronizing the actual pressure distribution images with the moving virtual route displayed on the display screen;
wherein, as the user walks or runs on the endless belt, the moving virtual route is displayed to the user synchronized with the footprints of the user.
