Trunk and Spine models for instrumented gait analysis

Abstract

There are several types of motion capture systems which can measure trunk and spine movement as a part of gait analysis. These range from wearable sensors to optoelectronic systems. This chapter focuses on models used within optoelectronic systems and covers both two- and three-dimensional models. This chapter while providing an outline of the current thorax and pelvis models highlights novel concepts in terms of 3-dimensional clusters. Latest methods on data analysis techniques using vector coding have been outlined which will facilitate comprehensive reporting of the movement data.
