The aim of this study was to evaluate the test-retest reliability of an integrated inertial sensor (IIS) for cervical range of motion assessment. An integrated inertial sensor was placed on the forehead center of thirty older adults (OA) and thirty younger adults (YA). Participants had to perform three continuous rotations, lateral bandings and flexion-extensions with their head. Test-retest reliability was assessed after 7 days. YA showed moderate to good agreement for rotation (0.54-0.82), lateral bending (0.74-0.8), and flexion-extension (0.74-0.81) movements and poor agreement for zero point (ZP). OA showed moderate to good agreement for rotation (0.65-0.86), good to excellent agreement in lateral bending (0.79-0.92), and poor to moderate agreement for flexion-extension (0.37-0.72). Zero point showed poor to moderate agreement. In conclusion, we can affirm that this IIS is a reliable device for cervical range of motion assessment in young and older adults; on the contrary, the ZP seems to be unreliable and the addition of an external reference point could help the subject to solve this shortcoming and reduce possible biases.
本研究的目的是评估用于颈椎活动度评估的集成惯性传感器（IIS）的重测信度。将一个集成惯性传感器放置在30名老年人（OA）和30名年轻人（YA）的额头中央。参与者必须用头部进行三次连续的旋转、侧弯和屈伸动作。7天后评估重测信度。年轻人在旋转（0.54 - 0.82）、侧弯（0.74 - 0.8）和屈伸（0.74 - 0.81）动作方面显示出中度到良好的一致性，而在零点（ZP）方面一致性较差。老年人在旋转（0.65 - 0.86）方面显示出中度到良好的一致性，在侧弯（0.79 - 0.92）方面显示出良好到优秀的一致性，在屈伸（0.37 - 0.72）方面显示出较差到中度的一致性。零点显示出较差到中度的一致性。总之，我们可以肯定，这种IIS是用于评估年轻人和老年人颈椎活动度的可靠设备；相反，零点似乎不可靠，增加一个外部参考点可能有助于受试者解决这一缺点并减少可能的偏差。
