A rise in neck pain cases has initiated an exponential interest in the assessment and treatment of cervical spine range of motion (CROM). Experimental limitations, however, have been reported as therapists strive to collect continuous, dynamic data to aid prognosis. This technical report seeks to explore the viability of using inertial sensors to reliably assess CROM. In recognition of the need for secure skin-sensor attachment, four combinations of sensor pairings were established and investigated based upon four clinically identifiable surface landmarks. Twelve participants were recruited and asked to perform three specific movement cycles in each plane (i.e. flexion-extension; rotation; lateral bending). The reliability of the peak CROM, and the movement pattern, recorded in each of the three movement cycles was statistically analysed using the intra-class correlation coefficient (ICC) and coefficient of multiple correlations (CMC). It was determined that the most reliable positions of the orientation sensors, with one adhered to the forehead and the other representing T4, enables data to be recorded with a reliability that is comparable to other CROM measuring techniques. Subsequently, it is concluded that inertial sensors represent a viable method to assess CROM.
颈部疼痛病例的增加引发了人们对颈椎活动范围（CROM）评估和治疗的极大兴趣。然而，随着治疗师努力收集连续的动态数据以辅助预后，实验局限性也已被报道。本技术报告旨在探讨使用惯性传感器可靠评估CROM的可行性。鉴于需要确保皮肤与传感器的牢固附着，基于四个临床可识别的表面标志建立并研究了四种传感器配对组合。招募了12名参与者，并要求他们在每个平面（即屈伸；旋转；侧屈）执行三个特定的运动周期。使用组内相关系数（ICC）和多重相关系数（CMC）对三个运动周期中记录的每个周期的CROM峰值和运动模式的可靠性进行了统计分析。确定了最可靠的定向传感器位置，一个贴在前额，另一个代表T4，能够以与其他CROM测量技术相当的可靠性记录数据。随后得出结论，惯性传感器是评估CROM的一种可行方法。
