Abstract
Pressure sores (PS), are frequent in subjects with spinal cord injuries, and to minimize PS these subjects must get used to change frequently their posture; useful informations to this aim may come testing healthy subjects and studying their kinematic behaviour during long sitting posture. Two different investigation systems have been developed to this aim in the Department of Mechanics and Aeronautics (DMA) of Rome University "La Sapienza": the two systems, a pressure map sensor arranged on a chair and a potentiometer-based device to measure trunk rotations at the basis of the spine are shown in this paper and their outputs are compared and correlated. The behaviour of ten healthy subjects is then evaluated during one hour sitting posture for preliminary considerations: there is a postural change every 7.7 ± 6.7 minutes in the frontal plane and every 5.7 ± 2.7 minutes in the sagittal plane.File | Dimensione | Formato | |
