着座姿勢における脊柱形状の計測

抄録

Human posture changes according to the task or purpose being performed, and the shape of the spine changes accordingly. It is essential to focus on the shape of the spine when evaluating posture In this study, we constructed a spine shape measurement system using a 3-axis acceleration sensor, and realized the measurement of spine shape corresponding to various seating postures, which has been difficult to measure so far. Using the constructed measurement system, the subjects were seated in a reclining chair under various conditions, and the spinal column shapes were measured and compared during the seating.
