Dynamic stability of locomotion plays an important role in running injuries, particularly during trail running where ankle injuries occur frequently. Several studies have investigated dynamic stability of locomotion using wearable accelerometer measurements. However, no study has reviewed how dynamic stability of locomotion is quantified using accelerometry. Therefore, the present review aims to synthetise the methods and findings of studies investigating stability related parameters measured by accelerometry, during locomotion on various surfaces, and among asymptomatic participants. A systematic search of studies associated with locomotion was conducted. Only studies including assessment of dynamic stability parameters based on accelerometry, including at least one group of asymptomatic participants, and conditions that occur during trail running were considered relevant for this review. Consequently, all retrieved studies used a non-obstructive portable accelerometer or an inertial measurement unit. Fifteen studies used a single tri-axial accelerometer placed above the lumbar region allowing outdoor recordings. From trunk accelerations, a combination of index of cycle repeatability and signal dispersion can adequately be used to assess dynamic stability. However, as most studies included indoor conditions, studies addressing the biomechanics of trail running in outdoor conditions are warranted.
运动的动态稳定性在跑步损伤中起着重要作用，特别是在经常发生脚踝损伤的越野跑中。一些研究已经使用可穿戴加速度计测量来研究运动的动态稳定性。然而，尚无研究综述使用加速度计量化运动动态稳定性的方法。因此，本综述旨在综合分析在各种表面上和无症状参与者中，使用加速度计测量的与稳定性相关的参数的研究方法和结果。对与运动相关的研究进行了系统检索。只有包括基于加速度计评估动态稳定性参数的研究，包括至少一组无症状参与者，以及在越野跑中发生的条件，才被认为与本综述相关。因此，所有检索到的研究都使用了非阻塞式便携式加速度计或惯性测量单元。有 15 项研究使用了一个放置在腰部上方的单三轴加速度计，允许在户外进行记录。从躯干加速度中，循环可重复性指数和信号分散度的组合可以充分用于评估动态稳定性。然而，由于大多数研究都包括室内条件，因此需要研究在户外条件下越野跑的生物力学。
