We have just released the pre-print of a research paper on the estimation of the centre of mass using motion capture devices, in people sitting in their wheelchairs. To estimate the centre of mass, we need to locate each body segment in space. However, it is difficult to precisely locate the pelvis, hips and lower back in people in wheelchairs, since the wheelchair hides these points. In this article, we present a method to achieve this estimation, and we test its accuracy using a reference method based on force platforms.
