Purpose: The purpose of this study was to investigate the mechanism of the fluctuation in the shear force applied to the buttocks. Method: The subjects were 11 healthy adult men without leg or trunk diseases. The amount of force applied to the buttocks was measured by using a force plate, and a pressure and shear force sensor was used to measure the timing of the force applied to the back support. Results: The average value of the shear force applied to the buttocks was 9.4 +/- 2.4 (% BW) in the initial upright position (IUP), 9.3 +/- 1.2 (% BW) in the fully reclined position (FRP), and 15.0 +/- 2.9 (% BW) in the returning to an upright position (RUP). Significant differences appeared between the RUP and the other positions. Conclusions: The results of this study suggested that the adjustment of the axes of rotation of the back support and trunk- pelvis and the release of the remaining shear force after the back support is reclined are important for the prevention of decubitus ulcers.
