“…Sacral sitting is a poor seated posture with a posterior pelvic tilt and thoracic kyphosis1 ) . It is typically observed in frail older adults using a wheelchair, and occurs when they lack the ability to retain a seated posture and/or their body size and function do not match the size and structure of the wheelchair2 ) .…”

[Purpose] The purpose of this study was to investigate the influence of sacral sitting in a wheelchair on contact pressure on the buttocks and back, and shear force on the ischial region. [Subjects and Methods] Twenty-six healthy adults assumed two postures while seated in a wheelchair: a basic sitting posture, and sacral sitting with the pelvis tilted posteriorly and the ischium slid forward by 5 cm relative to its position in the basic sitting posture. The inclination angle of the sagittal pelvic line, contact pressures and contact areas on the buttocks and back, and the shear force generated by sliding the ischial region forward were measured. [Results] Posterior pelvic tilt was significantly greater during sacral sitting. Maximum contact pressures on the buttocks and ischial region were significantly lower during sacral than during basic sitting. However, maximum contact pressure on the back, the contact areas of the buttocks and back, and the shear force generated by sliding the ischial region forward were significantly greater during sacral sitting. [Conclusion] Sacral sitting in a wheelchair increases the maximum contact pressure on the back, contact areas of the buttocks and back, and the shear force generated by sliding the ischial region forward.

“…The dimensions of wheelchairs and their seats have been noted as possible causes of pelvic posterior tilt 7 ) , and the use of a wheelchair cushion is therefore recommended 8 ) . The effect of using a wheelchair cushion with anchor support 6 ) and notches for the thigh section on the propulsion side 9 ) have been reported for hemiplegic subjects.…”

[Purpose] This study sought to ascertain whether, in hemiplegic patients, the effect of a wheelchair cushion to suppress pelvic posterior tilt when initiating wheelchair propulsion would continue in subsequent propulsions. [Subjects] Eighteen hemiplegic patients who were able to propel a wheelchair in a seated position participated in this study. [Methods] An adjustable wheelchair was fitted with a cushion that had an anchoring function, and a thigh pad on the propulsion side was removed. Propulsion movements from the seated position without moving through three propulsion cycles were measured using a three-dimensional motion analysis system, and electromyography was used to determine the angle of pelvic posterior tilt, muscle activity of the biceps femoris long head, and propulsion speed. [Results] Pelvic posterior tilt could be suppressed through the three propulsion cycles, which served to increase propulsion speed. Muscle activity of the biceps femoris long head was highest when initiating propulsion and decreased thereafter. [Conclusion] The effect of the wheelchair cushion on suppressing pelvic posterior tilt continued through three propulsion cycles.
