Pressure-related decubitus ulcers are a frequent disability and life-threatening complication in the management and rehabilitation of patients with spinal cord injuries. This paper describes a system developed to quantitate and evaluate a patient's response to wheelchair pressure-relief cushions. Maximum pressure and the tissue pressure distribution on six varieties of wheelchair cushions were determined for a sample of 57 patients with a history of decubitus ulcers. Wide variations in (mean) maximum pressure were observed. However, even greater variations were found in the distribution (bony/soft tissue) of the pressure. These data demonstrate that no single cushion was clearly superior in relieving pressure for all patients. Therefore, individualization of wheelchair cushions for each patient may be essential in order to minimize the probability that the person will experience a tissue-pressure problem.
与压力相关的褥疮是脊髓损伤患者管理和康复中常见的致残且危及生命的并发症。本文描述了一种开发出来的系统，用于量化和评估患者对轮椅减压坐垫的反应。对57名有褥疮病史的患者样本，测定了六种不同轮椅坐垫上的最大压力和组织压力分布。观察到（平均）最大压力存在很大差异。然而，在压力的分布（骨/软组织）方面发现了更大的差异。这些数据表明，没有一种坐垫在为所有患者减压方面明显更优。因此，为每位患者定制个性化的轮椅坐垫可能至关重要，以便将患者出现组织压力问题的可能性降至最低。
