该项目研究了运动学步态参数作为法医预测个人携带高达其体重20%的隐蔽重量包的影响的指标。最初的逆动力学方法与计算代数相结合，提供了12名受试者在正常行走时步态站立阶段的腿部关节角度。下面的文章描述了对关节角度数据的附加生物力学分析，以产生进一步表征人体运动的运动学和运动学参数。结果包括髋关节、膝盖和脚踝的旋转速度和加速度，以及这些关节产生的惯性矩和动能。报道的结果表明，隐蔽性负荷量、体重指数和性别对关节动力学没有统计学意义的影响(p>；0.05)。然而，加载运动学和非加载运动学的比率对步态有一些统计上的影响(p<；0.05)。正在进行的研究正在检查另一个背负量更大的受试者队列，以努力确定步态特征的变化是一种反恐方法。
This project examines kinematic gait parameters as forensic predictors of the influence associated with individuals carrying concealed weighted packs up to 20% of their body weight. An initial inverse dynamics approach combined with computational algebra provided lower limb joint angles during the stance phase of gait as measured from 12 human subjects during normal walking. The following paper describes the additional biomechanical analysis of the joint angle data to produce kinetic and kinematic parameters further characterizing human motion. Results include the rotational velocities and accelerations of the hip, knee, and ankle as well as inertial moments and kinetic energies produced at these joints. The reported findings indicate a non-statistically significant influence of concealed pack load, body mass index, and gender on joint kinetics (p>0.05). Ratios of loaded to unloaded kinematics, however, identified some statistical influence on gait (p<0.05). On-going studies are examining an additional subject cohort with greater pack loads in an effort to identify alterations in gait signatures as a counter-terrorism approach.
