Two-dimensional Gait Analysis Using a Tracking Software on a Three-dimensional Projection

Gait analysis is the methodic measurement and evaluation of all the different factors that affect human locomotion. It can be applied for rehabilitation purposes and lower the risks of injuries. Modern technology has lead to an amount of precise methods of executing gait analysis. The disadvantages with these are that they often are expensive and only available at a few specially built locations. The need for an inexpensive, yet reliable and portable solution that can analyze gait are there. This study focuses on a method including four laser diodes which are tracked using a specially designed software. The laser diodes are located on each shoulder of the test subject and attached to a helmet. The laser diodes form a projection which are recorded with a video camera. The recordings are then analyzed in Matlab. An analysis is then done trying to distinguish differences in the motion patterns. However, this novel method should be further tested prior to use.
