There is considerable value in developing tools capable of accurately and reliably determining when bruises were inflicted in humans. Previous work has focused on the visual changes observed in a bruise as the injury develops and heals. However, due to variables such as how and where on the body the bruise was inflicted, differing tissue compositions at the injured skin site between individuals and inter- and intra-observer variation; a technique sufficiently robust for use in a clinical or medicolegal setting has not yet been identified. In this study we present a series of photographs taken under controlled conditions illustrating standardised bruises induced on participants using a weight dropping mechanism. We show that variation in the appearance of bruises over time across individuals is large and, although photography may be a suitable technique for the recording of injuries, it is not sufficiently reliable for determining the age of a bruise.
开发能够准确可靠地确定人体瘀伤何时形成的工具具有重要价值。以前的工作主要集中在观察损伤发展和愈合过程中瘀伤的视觉变化上。然而，由于瘀伤是如何以及在身体的哪个部位造成的、受伤皮肤部位在个体之间以及观察者之间的组织成分差异等变量；尚未确定一种足够强大的技术，可用于临床或法医学环境。在这项研究中，我们展示了一系列在受控条件下拍摄的照片，这些照片展示了使用重物掉落机制在参与者身上引起的标准化瘀伤。我们表明，个体之间随着时间的推移瘀伤外观的变化很大，尽管摄影可能是记录损伤的一种合适技术，但它对于确定瘀伤的年龄并不足够可靠。
