对于中枢神经系统（CNS）创伤性或非创伤性疾病的永久性轮椅使用者，坐位获得性压疮（SAPU）是一个巨大的医学挑战。本综述的目的是总结目前已知的SAPU的病因，特别是其严重形式，根据美国国家压疮咨询小组，SAPU现在可能被归类为“深部组织损伤”。具体来说，这篇综述侧重于深SAPU的生物力学方面，并描述了相关的生物工程方法和研究证据。它讨论了深层组织中独特的生物力学条件，这些条件是由与中枢神经系统疾病相关的长期坐着引起的，总的来说，目前的综述表明，在这类患者中避免界面压力超过32 mmHg并不一定是“压力缓解”。
Sitting-acquired pressure ulcers (SAPU) in permanent wheelchair users with traumatic or non traumatic disorders of the central nervous system (CNS) are a great medical challenge. The purpose of this review is to summarise what is currently known concerning the aetiology of SAPU, particularly in its severe form, which may now be classified as a 'deep tissue injury' according to the US National Pressure Ulcer Advisory Panel. Specifically, this review focuses on biomechanical aspects of deep SAPU and describes the relevant bioengineering methodologies and research evidence. It discusses the unique biomechanical conditions in deep tissues, which are caused by chronic sitting associated with CNS disorders, and overall, the present review indicates that avoiding interface pressures above 32 mmHg in such patients is not necessarily a 'pressure relief.'
