| Outline of Final Research Achievements |
In this study, we developed a quantitative measurement system for sitting pose that is easy to apply clinically and developed a sensor to measure shear stress acting on the buttocks. We measured the inclination angle of the sternum line and the shear force under the ischial tuberosities for a typical sitting posture of nine healthy subjects using a measurement system integrating them. As a result, the shear force toward the back (direction of the backrest) acts under the ischial tuberosity regardless of posture, showed a tendency to increase by forward-leaning posture. Furthermore, when the trunk was tilted to the side, the shear force in the direction opposite to the inclined side showed a tendency to increase. In addition, it was confirmed that measurements were made at the elderly facilities, and it was possible to fully utilize the constructed measurement system at the site, and no major problems occurred in the measurement.
