We report a case of a 28-year-old man with a complete C5 level spinal cord injury who developed persistent redness over his ischial tuberosities due to his wheelchair cushion cover's hammock effect. He had purchased wheelchairs and cushions in 2004 and 2008. Persistent redness occurred over his ischial tuberosities when using the second cushion purchased in 2008. Pressure mapping did not detect any differences in pressure over the ischial tuberosities with different cushions. When comparing cushions without their covers, we noticed that the first cushion had a greater air volume than the second cushion. We exchanged the cushion covers to evaluate the hammock effect due to different covers. We found that the redness occurred at any time the second cushion cover was used. After the patient's family changed the top of the second cushion cover to a more elastic material, the redness resolved. As we were unable to detect the influence of the hammock effect using pressure mapping, it would be useful to develop an alternative method to evaluate this phenomenon. It would also be valuable to find a readily available solution for other patients experiencing this problem.
我们报告了一例 28 岁男性患者，其 C5 完全性脊髓损伤，因轮椅坐垫套的悬带效应导致坐骨结节处持续发红。他在 2004 年和 2008 年购买了轮椅和坐垫。在使用 2008 年购买的第二个坐垫时，坐骨结节处持续发红。压力映射并未检测到不同坐垫在坐骨结节处的压力有任何差异。当比较没有坐垫套的坐垫时，我们注意到第一个坐垫的空气体积大于第二个坐垫。我们交换了坐垫套以评估由于不同的坐垫套导致的悬带效应。我们发现，只要使用第二个坐垫套，就会出现发红的情况。当患者家属将第二个坐垫套的顶部更换为更有弹性的材料后，发红的情况得到了缓解。由于我们无法使用压力映射检测到悬带效应的影响，因此开发一种替代方法来评估这种现象将很有用。对于其他遇到此问题的患者，找到一个现成的解决方案也很有价值。
