A wheelchair is usually a source of mobility for people with moderate to severe cerebral palsy, who are unable to walk. They spend long periods of time sitting in their wheelchair, which can affect their head and neck alignment. Opening the seat to back support angle of the wheelchair can modify realignment of body segments and improve posture. : To examine the effect of seat to back support angle adjustments on head, neck, and shoulder postural alignment in people with cerebral palsy. : Nine participants with cerebral palsy who use a wheelchair for mobility sat in a research wheelchair. Sagittal head angle (SHA), cervical angle (CVA), and shoulder angle (SA) from photographs were examined using the Coach's Eye device during three different seat to back support angles of the wheelchair (90°, 100°, 110°). : There were significant differences in mean SHA and CVA among the different seat to back support angles ( < .001). However, there was no significant difference in mean SA. : Head (SHA) and (CVA) alignment was closest to neutral posture with seat to back support angles set at 110°. Thus, adjusting the wheelchair back support to a 110º would provide the most appropriate sagittal head and cervical angle for this population.
轮椅通常是中度至重度脑瘫患者的移动工具，这些患者无法行走。他们长时间坐在轮椅上，这可能会影响他们的头部和颈部对齐方式。打开轮椅的座位到椅背支撑角度可以调整身体部位的重新对齐，从而改善姿势。目的：研究座位到椅背支撑角度的调整对脑瘫患者头部、颈部和肩部姿势对齐的影响。方法：9 名使用轮椅进行移动的脑瘫患者坐在研究轮椅上。使用 Coach's Eye 设备在轮椅的三个不同座位到椅背支撑角度（90°、100°、110°）下拍摄照片，检查矢状头角（SHA）、颈椎角（CVA）和肩部角（SA）。结果：不同座位到椅背支撑角度之间的平均 SHA 和 CVA 存在显著差异（<0.001）。然而，平均 SA 没有显著差异。结论：在座位到椅背支撑角度设置为 110°时，头部（SHA）和（CVA）的对齐方式最接近中立姿势。因此，将轮椅的靠背支撑调整到 110°可以为该人群提供最合适的矢状头部和颈椎角度。
