| Research Abstract |
1. To examine the relationships between the functional head-neck alignment of patients with severe disabilities and the Seating Buggy's resulting seating support surface, we measured the configuration of seating support surface. Twenty one subjects whose head alignments were poor were used. Three major lines were identified. The angle of the thoracic line was approximately the same as the pelvic line, and parallel to the back-support pipe. However, the angle between these two lines was by comparison about two times greater. It was speculated that deeper thoracic support forms the anchorage for the curved upper trunk from the underneath, depending on the patient's spinal deformity.
2. A new wheelchair seating system that features an adjustable back support has been developed to suggest a new sitting posture. To investigate which back support features provide proper head-neck alignment, we compared two new adjustable back support wheelchairs with a conventional wheelchair. Twenty-six able

-bodied participated, each sitting in each of the three wheelchairs in five ways. Three major structures were identified from the two new wheelchairs, namely the angles of the thoracic line, pelvic line, and thoracolumbar line. It was speculated that a thoracolumbar line establishes a stable basis for the proper head-neck position.
3. Fifty-eight seat surfaces of old wheelchairs for elderly were scanned with the TRiDY. Twenty-one were classified as upper loosening pattern, 11 were as upper/middle pattern, 15 were middle pattern. It was speculated that elderly who sit with slumped posture were on the middle or upper/middle pattern.
4. A new prototype chair that features a flexible back-support with the thoracolumbar line has been developed. Reclining movements of people on the new prototype chair were analyzed with 3D movement analysis system and pressure measurement system. The reclining movement was triggered by the distal foot. It was speculated that the strength used for the reclining of the prototype chair was smaller than that of the commonly used chair. Less
