Foundational examination of techno-adaptability of wheelchair for adults with cerebral palsy

1. 为了研究严重残疾患者的头颈功能对齐与座椅童车产生的座位支撑面之间的关系，我们测量了座位支撑面的配置。使用了21名头部对准不良的受试者。确定了三条主要路线。胸椎线的角度与骨盆线大致相同，并平行于背部支撑管。然而，相比之下，这两条线之间的夹角要大两倍。据推测，根据患者的脊柱变形情况，较深的胸椎支撑从下方形成弯曲的上躯干的锚固。一种新的轮椅座椅系统，以可调节的背部支撑为特色，已经开发出一种新的坐姿。为了研究哪一种椅背支撑功能能提供适当的头颈对齐，我们比较了两种新的可调节椅背支撑轮椅和传统轮椅。二十六个身体健全的人参加了实验，每人以五种方式坐在三把轮椅上。从两个新轮椅上确定了三个主要结构，即胸线、骨盆线和胸腰线的角度。据推测，胸腰线为正确的头颈位奠定了稳定的基础。利用TRiDY对58台老年轮椅座椅表面进行扫描。上部松动型21例，上部/中部型11例，中部型15例。据推测，以瘫坐姿势坐着的老年人属于中上/中模式。一种新的原型椅子，其特点是具有灵活的背部支持和胸腰椎线。利用三维运动分析系统和压力测量系统对人在新型原型椅上的倾斜运动进行了分析。倾斜运动是由远端足触发的。据推测，原型椅的斜倚使用的强度比常用的椅子要小。少

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 … More -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
