An impaired neuromuscular function of the trunk and lower extremities makes that many wheelchair-users suffer postural instability and have problems with the performance of functional movement during activities of daily life. To increase the base of support and to bring the body centre of mass closer to the support surface, wheelchair-users who lack postural control often adopt a static kyphotic spinal posture with posterior tilted pelvis. The inability to change body posture underlines the importance for automatic chair modification of the help of others. Because this latter often involves a time consuming and labour intensive activity, we strive to prevent mobility problems by the use of dynamic systems that adjust sitting posture an d relieve body structures periodically.
