通过三轴加速度计测量了步行和跑步过程中的胫骨加速度。将加速度计固定到插入一名志愿受试者右胫骨的斯坦曼针的自由端。胫骨加速度的模式在每个实验条件下几乎没有逐步变化。在脚着地后，根据鞋子的不同，在行走过程中产生的胫骨加速度达到2.7和3.7 g之间。胫骨在跑步过程中经历了10.6 g的最大加速度。在前后（AP）和内外（ML）方向上记录的胫骨加速度的高值清楚地揭示了测量加速度的所有三个分量以量化运动活动期间下肢所经历的电击幅度的重要性。
Measurements of tibial acceleration during walking and running were obtained by means of a triaxial accelerometer. The accelerometer was fixed to the free end of a Steinmann pin inserted into the right tibia of one volunteer subject. The patterns of tibial acceleration showed little step-to-step variation within each experimental condition. Following foot strike and depending upon footwear, the resultant tibial acceleration reached between 2.7 and 3.7 g during walking. The tibia experienced maximal accelerations of 10.6 g during running. The high values of tibial acceleration recorded in the antero-posterior (AP) and medio-lateral (ML) directions clearly revealed the importance of measuring all three components of acceleration to quantify the magnitude of the shock experienced by the lower limbs during locomotor activities.
