Concussion awareness has become more prevalent in the past decade, leading to growing calls for prevention programs such as neck strengthening. However, previous research work has shown that not all training programs have been effective, and there is a need for a reliable testing device to measure cervical strength dynamically before and after training. Therefore, this work proposes a novel Concussion Active Prevention Testing Device composed of inertial measurement units mounted on the head and a custom-designed frame to measure head kinematics during controlled sub-concussive impacts. Through an experimental study with able-bodied participants, the proposed testing device demonstrated high intra-participant repeatability between waveforms of the head acceleration and angular velocity in the sagittal plane (multiple correlation coefficient of 80%). Similarly, good and excellent intra-class correlation coefficients were obtained for head injury metrics, including range, peak, Gadd severity index, head injury criterion, and range of motion. Finally, the results showed that significantly higher head injury metrics were measured for female participants, which was in line with the findings of previous research works. We conclude that the proposed testing device can be used to measure repeatable and informative metrics for evaluating the effectiveness of athletes’ neck strengthening program.

在过去十年中，脑震荡意识变得越来越普遍，导致对诸如颈部加强等预防计划的呼声越来越高。但是，先前的研究工作表明，并非所有的训练计划都有效，因此需要一种可靠的测试装置来在训练前后动态地测量宫颈的力量。因此，这项工作提出了一种新型的脑震荡主动预防测试装置，该装置由安装在头部的惯性测量单元和定制设计的框架组成，以在受控的次脑震荡撞击中测量头部的运动学。通过对健全参与者的实验研究，所提出的测试设备证明了头部加速度波形与矢状面角速度之间的参与者内部重复性较高（80％的相关系数）。类似地，获得了关于头部受伤指标的良好和出色的组内相关系数，包括范围，峰值，Gadd严重程度指数，头部受伤标准和运动范围。最后，结果表明，女性参与者的头部受伤指标明显更高，这与以前的研究工作相吻合。我们得出结论，建议的测试设备可用于测量可重复性和信息量度，以评估运动员颈部强化计划的有效性。对于头部受伤指标，包括范围，峰值，Gadd严重程度指数，头部受伤标准和运动范围，均获得了良好和出色的组内相关系数。最后，结果表明，女性参与者的头部受伤指标明显更高，这与以前的研究工作相吻合。我们得出结论，建议的测试设备可用于测量可重复性和信息量度，以评估运动员颈部强化计划的有效性。对于头部受伤指标，包括范围，峰值，Gadd严重程度指数，头部受伤标准和运动范围，均获得了良好和出色的组内相关系数。最后，结果表明，女性参与者的头部受伤指标明显更高，这与以前的研究工作相吻合。我们得出结论，建议的测试设备可用于测量可重复性和信息量度，以评估运动员颈部强化计划的有效性。
