Measurement of the buttock skin initial tensile strain induced by a sitting posture relative to a standing posture. Measurement was performed on the subject in the same hip and knee joint configuration as that in the sitting posture used to record MRI images, i.e., 80° hip flexion and 90° knee flexion. Buttock skin initial strain was measured by images of an array of dots painted on the buttock skin. Green strain [21] was calculated for an area of 15 × 15 mm2.
