Self-selected walking speed is an important measure of ambulation ability used in various clinical gait experiments. Inertial sensors, i.e., accelerometers and gyroscopes, have been gradually introduced to estimate walking speed. This research area has attracted a lot of attention for the past two decades, and the trend is continuing due to the improvement of performance and decrease in cost of the miniature inertial sensors. With the intention of understanding the state of the art of current development in this area, a systematic review on the exiting methods was done in the following electronic engines/databases: PubMed, ISI Web of Knowledge, SportDiscus and IEEE Xplore. Sixteen journal articles and papers in proceedings focusing on inertial sensor based walking speed estimation were fully reviewed. The existing methods were categorized by sensor specification, sensor attachment location, experimental design, and walking speed estimation algorithm.
自选步行速度是各种临床步态实验中常用的步行能力的重要衡量指标。惯性传感器（如加速度计和陀螺仪）已逐渐被引入以估计步行速度。在过去的二十年中，这个研究领域引起了很多关注，并且由于微型惯性传感器的性能提高和成本降低，这种趋势仍在继续。为了了解该领域当前发展的最新情况，我们在以下电子引擎/数据库中对现有的方法进行了系统回顾：PubMed、ISI Web of Knowledge、SportDiscus 和 IEEE Xplore。对 16 篇专注于基于惯性传感器的步行速度估计的期刊文章和会议论文进行了全面回顾。根据传感器规格、传感器附着位置、实验设计和步行速度估计算法对现有方法进行了分类。
