目的 研究不同轮椅空间倾斜和倾斜角度对脊髓损伤 (SCI) 轮椅使用者骶骨皮肤灌注的影响。重复测量、干预和结果测量设计。大学研究实验室。患有 SCI 的电动轮椅使用者 (N=11)。不同轮椅倾斜角度和倾斜角度的六种方案被随机分配给参与者，包括（1）15°空间倾斜和100°倾斜，（2）25°空间倾斜和100°倾斜，（3）35°空间倾斜和100°倾斜，（4）15°空间倾斜和120°倾斜，（5）25°倾斜空间倾斜和 120° 倾斜，以及 (6) 35° 空间倾斜和 120° 倾斜。每个方案包括 5 分钟的直立坐姿和 5 分钟的倾斜和斜躺时间。使用激光多普勒血流计测量骶骨（右髂后上棘和相邻棘突之间的中点）和右坐骨结节上的皮肤灌注。当从直立位置改变为倾斜和倾斜位置（N.S.）时，骶骨皮肤灌注在各种空间倾斜和倾斜角度的所有六种方案中均未显示出显着差异。然而，正如之前报道的，坐骨结节上的皮肤灌注在 15°、25° 和 35° 空间倾斜与 120° 倾斜结合时以及在 35° 空间倾斜与 100° 倾斜结合时显示显着增加 (P<.0083)。我们的研究结果表明，当从直立位置改变为倾斜和倾斜位置时，轮椅的空间倾斜和倾斜增强了坐骨结节上的皮肤灌注，而不减少骶骨皮肤灌注。
To investigate the effect of various wheelchair tilt-in-space and recline angles on sacral skin perfusion in wheelchair users with spinal cord injury (SCI). Repeated measures, intervention and outcomes measure design. University research laboratory. Power wheelchair users with SCI (N=11). Six protocols of various wheelchair tilt-in-space and recline angles were randomly assigned to the participants, including (1) 15° tilt-in-space and 100° recline, (2) 25° tilt-in-space and 100° recline, (3) 35° tilt-in-space and 100° recline, (4) 15° tilt-in-space and 120° recline, (5) 25° tilt-in-space and 120° recline, and (6) 35° tilt-in-space and 120° recline. Each protocol consisted of a 5 min upright sitting and a 5 min tilted and reclined period. Skin perfusion over the sacrum (midpoint between the right posterior superior iliac spine and adjacent spinous process) and right ischial tuberosity was measured using laser Doppler flowmetry. Sacral skin perfusion did not show a significant difference in all six protocols of various tilt-in-space and recline angles when changing from an upright to a tilted and reclined position (N.S.). However, as previously reported, skin perfusion over the ischial tuberosity showed a significant increase at 15°, 25°, and 35° tilt-in-space when combined with 120° recline and at 35° tilt-in-space when combined with 100° recline (P<.0083). Our results indicate that wheelchair tilt-in-space and recline enhances skin perfusion over the ischial tuberosities without reducing sacral skin perfusion when changing from an upright to a tilted and reclined position.
