Axial spondylarthritis (axSpA) is a chronic inflammatory disease of the spine that can be associated with loss of physical function, mobility and upright postural impairment. Established tools for the assessment of function that are largely based on subjective perception are semiquantitatively recorded by standardized questionnaires (Bath ankylosing spondylitis functional index, BASFI), while measurement of spinal mobility of patients with axSpA is based on physical examination of various movement regions particularly the axial skeleton (Bath ankylosing spondylitis metrology index, BASMI). Recently, a performance test has been added to assess the range of motion and speed of certain tasks (AS performance-based improved test, ASPI); however, since these tests have limited reliability and reproducibility, more objective tests would be desirable. In this study the spinal mobility of patients with axSpA was quantified using the Epionics SPINE device (ES) and data were evaluated using the outcome measures in rheumatology (OMERACT) criteria. The ES automatically measures various patterns of spinal movements using electronic sensors, which also assess the range and speed of carrying out movements. Patients with back pain from other causes and persons without back pain served as controls. The measurement results obtained with ES differed between the groups and correlated with BASMI values (r = 0.53-0.82, all p = <0.03). Patients with radiographically detectable axSpA had more limited and slower mobility than those with non-radiographically detectable axSpA. Overall, the results presented here suggest that ES measurements represent a valid and objective measurement procedure of spinal mobility for axSpA patients.
轴性脊柱关节炎（axSpA）是一种脊柱慢性炎症性疾病，可伴有身体功能丧失、活动能力下降和直立姿势受损。现有的功能评估工具主要基于主观感受，通过标准化问卷（巴斯强直性脊柱炎功能指数，BASFI）进行半定量记录，而axSpA患者脊柱活动度的测量则基于对各个运动区域尤其是中轴骨骼的体格检查（巴斯强直性脊柱炎测量指数，BASMI）。最近，增加了一项性能测试来评估某些任务的运动范围和速度（基于AS性能改进测试，ASPI）；然而，由于这些测试的可靠性和可重复性有限，因此需要更客观的测试。在本研究中，使用Epionics SPINE设备（ES）对axSpA患者的脊柱活动度进行量化，并使用风湿病学疗效指标（OMERACT）标准对数据进行评估。ES使用电子传感器自动测量脊柱运动的各种模式，还可评估运动的范围和速度。以其他原因引起背痛的患者和无背痛的人作为对照。ES获得的测量结果在各组之间存在差异，并且与BASMI值相关（r = 0.53 - 0.82，所有p = <0.03）。影像学可检测到axSpA的患者比影像学不可检测到axSpA的患者活动度更受限且更缓慢。总体而言，此处呈现的结果表明，ES测量代表了一种针对axSpA患者脊柱活动度的有效且客观的测量方法。
