Video analysis system of the gait cycle and posture of people wearing high heels

Abstract

Gait cycle analysis is a comprehensive source of information, usable in the medical field, in locomotion, sporting recovery procedures or to increase performance in various sporting fields. Study methods of walking cycle parameters are very diverse, starting from biomechanical analysis, computer simulations and modelling, and completing with video analysis of kinematic and dynamic parameters. The use of optical and video methods is very widespread in all medical, sporting, ergonomic and even economic fields. Thus, the first part of the paper analysis the general aspects regarding the use of optical methods of acquisition and processing of video sequences of the normal gait cycle. Also, in the same context of the introductory part of the paper the aspects of the biomechanics of the normal and high heels cycle for the females are presented. In the second part of the paper is presented an experimental setup for investigating, with the sample of subjects chosen, the cycle of gait with shoes having different dimensions of the heel height. In the third part of the paper are presented the recordings made on footscan pressure plate and also the data acquisition on the especially sensory insole worn by the subjects. In the final part of the paper are presented the results of the processing of this information and the conclusions from the experiment.
