撞击前跌倒检测已被提出为有效的跌倒预防策略。特别是，它可以帮助在坠落冲击之前激活按需坠落伤害预防系统（例如，充气臀部保护器），从而直接防止与坠落相关的身体伤害。本文对跌倒检测技术进行了系统的综述，重点介绍了跌倒检测设备、跌倒检测指标、跌倒检测算法以及跌倒检测评价的福尔斯类型等方面的研究现状。此外，还审查了现有的撞击前跌倒检测解决方案的性能，并报告了其灵敏度、特异性和检测/交货时间。本文还总结了现有碰撞前跌倒检测研究的局限性，并提出了该领域未来的研究方向。
Pre-impact fall detection has been proposed to be an effective fall prevention strategy. In particular, it can help activate on-demand fall injury prevention systems (e.g. inflatable hip protectors) prior to fall impacts, and thus directly prevent the fall-related physical injuries. This paper gave a systematical review on pre-impact fall detection, and focused on the following aspects of the existing pre-impact fall detection research: fall detection apparatus, fall detection indicators, fall detection algorithms, and types of falls for fall detection evaluation. In addition, the performance of the existing pre-impact fall detection solutions were also reviewed and reported in terms of their sensitivity, specificity, and detection/lead time. This review also summarized the limitations in the existing pre-impact fall detection research, and proposed future research directions in this field.
