Abstract

Measurement of the cervical range of motion (CROM) is significant for early diagnosis of cervical spondylosis and determination of the severity of the disease. Aiming at the problem of convenient and continuous measurement of CROM and the reduction of the impact of data fluctuations, this paper proposes a low-cost method for testing and analyzing CROM. This paper analyzes the correspondence between smartphone orientation sensor angle and CROM, obtains smartphone orientation sensing data, and uses the extreme-point symmetric mode decomposition method by calculating the energy of the difference value to extract the adaptive global mean curve of the CROM data, and calculates the cervical ROM. The statistical analysis of the CROM test results is carried out. Results show that the method proposed can obtain the CROM including flexion and extension, lateral flexion, and rotation in a single measurement, which has the advantages of continuous measurement and low cost.

测试和分析颈椎活动范围的低成本方法

颈椎活动范围（CROM）的测量对于早期诊断颈椎病和确定疾病的严重程度具有重要意义。针对CROM测量的便捷性和连续性问题，以及减少数据波动的影响，本文提出了一种低成本的CROM测试和分析方法。本文分析了智能手机方位传感器角度与CROM之间的对应关系，获取了智能手机方位传感数据，并通过计算差值的能量，采用极值点对称模分解法提取了CROM数据的自适应全局均值曲线，计算了颈椎ROM。对 CROM 测试结果进行了统计分析。结果表明，所提出的方法可以在一次测量中获得包括屈伸、侧屈和旋转在内的颈椎ROM，具有连续测量和成本低的优点。
