摘要

提出了一种动态颈部模型，用于功能评估或人体工程学研究，使用从传统生物力学工具（如视频摄影测量和力平台）获得的数据。通过回归方程获得头部和颈部惯性参数，并通过校准过程进行细化，以提高精度。通过视频摄影测量记录头部运动，其中标记坐标用于计算有限位移、线速度和角速度以及加速度。逆动力学方法用于估计C7椎骨水平的力和力矩以及产生的肌肉力量。该模型通过一项有30名参与者参加的实验研究进行了验证，并将其估计值与从力平台获得的测量值进行了比较。比较旨在评估该模型的准确性和可靠性。结果显示非常一致，相关性为0.976或更高，标准误差小于头部重量的1%关键词：生物力学、生物力学模型、颈部、人体工程学、功能评估

VALIDATION OF A DYNAMIC MODEL OF THE NECK FOR APPLICATIONS IN ERGONOMICS AND FUNCTIONAL ASSESSMENT

A dynamic neck model is proposed for functional assessment or ergonomic studies using data obtained from conventional biomechanical tools such as video photogrammetry and force platforms. The head and neck inertial parameters are obtained through regression equations and refined through a calibration process to improve accuracy. Head movement is recorded through video photogrammetry, where marker coordinates are used to calculate finite displacements, linear and angular velocities, and accelerations. An inverse dynamics approach is used to estimate the forces and moments at the C7 vertebral level and the generated muscle power. The model was validated through an experimental study with 30 participants, where its estimates were compared to the measurements obtained from a force platform. The comparison aimed to assess the accuracy and reliability of the model. The results show excellent agreement, with a correlation of 0.976 or higher and a standard error of less than 1% of the head weight Keywords: Biomechanics, biomechanical model, neck, ergonomics, functional assessment
