Abstract

In this study, we aimed to examine whether a wheelchair cushion placed directly atop a sling seat or deflection of the sling seat compensated by a pad along with the placement of a wheelchair cushion changed sitting pressure. Additionally, we examined whether these additions changed sitting comfort. For twenty healthy adults who consented to participate, measurements were taken for three types of cushions, each with and without padding, under six conditions. The cushion types tested included air (cushion A), urethane foam (cushion U), and three-dimensional thermoplastic elastomer (cushion T). A pressure distribution measurement equipment was used for the measurements. Following the measurement, the comfort of the wheelchair cushion was measured. The ischial area pressure of the cushion A pad was significantly lower than that without the pad. Cushions U and T were for ischial area pressure with a pad, resulting in a decreasing trend in ischial area pressure with a pad compared to that without a pad; however, the difference was insignificant. For all cushions, sitting comfort was significantly better in all groups with padding than in those without. In conclusion, ischial pressure can be dispersed by placing a pad on the seat surface of a wheelchair cushion, and pads were suggested to improve sitting comfort for all cushions.

给轮椅座椅加垫可减少骶骨压力,提高坐姿舒适度。
在这项研究中,我们的目的是研究直接放在吊衣座椅上的轮椅垫或由垫子补偿的吊衣座椅偏移以及轮椅垫的放置是否会改变坐压。此外,我们还研究了这些附加装置是否会改变坐姿舒适度。在六种条件下,我们对二十名同意参与的健康成年人的三种坐垫进行了测量,每种坐垫都有衬垫和无衬垫。测试的坐垫类型包括空气坐垫(坐垫 A)、聚氨酯泡沫坐垫(坐垫 U)和三维热塑弹性体坐垫(坐垫 T)。测量使用了压力分布测量设备。测量结束后,对轮椅坐垫的舒适度进行了测量。垫子 A 的骶骨区压力明显低于没有垫子的骶骨区压力。坐垫 U 和坐垫 T 的骶骨区压力有衬垫,与无衬垫相比,有衬垫的骶骨区压力呈下降趋势,但差异不明显。在所有坐垫中,有衬垫组的坐姿舒适度明显优于无衬垫组。总之,在轮椅坐垫的座面上放置垫子可以分散骶骨压力,建议在所有坐垫上放置垫子以提高坐姿舒适度。
