军用载重车的3-D步态分析在现有文献中没有得到很好的体现。本研究收集了三维下肢运动学和时空参数，以评估在高达32公斤的背包中携带负载的后续影响。结果表明，增加负荷后，膝关节屈伸活动度和骨盆旋转活动度明显减小。还观察到髋关节内收/外展和旋转以及骨盆倾斜增加。未观察到踝关节运动学变化。步态的时空参数的变化也是相当大的兴趣，即增加双支撑和减少首选的步幅长度进行负载的增加。分析军事或娱乐载荷搬运过程中的运动学可以拓宽有关运动相关损伤发展的知识，同时有助于为未来的载荷搬运系统提供以人为本的设计过程。这项研究的重要性是，有限的可用研究进行了调查的3-D下肢关节运动学负荷时。
The 3-D gait analysis of military load carriage is not well represented, if at all, within the available literature. This study collected 3-D lower limb kinematics and spatiotemporal parameters in order to assess the subsequent impact of carrying loads in a backpack of up to 32kg. Results showed the addition of load significantly decreased the range of motion of flexion/extension of the knee and pelvic rotation. Also seen were increases in adduction/abduction and rotation of the hip and pelvis tilt. No changes to ankle kinematics were observed. Alterations to the spatiotemporal parameters of gait were also of considerable interest, namely, an increase in double support and a decrease in preferred stride length as carried load increased. Analysing kinematics during military or recreational load carriage broadens the knowledge regarding the development of exercise-related injuries, while helping to inform the human-centred design process for future load carrying systems. The importance of this study is that limited available research has investigated 3-D lower limb joint kinematics when carrying loads.
