We aimed to examine whether ultrasound (US) is useful for evaluating spinal mobility and chest expansion in ankylosing spondylitis (AS) patients and determine a cutoff value to identify reduced sagittal lumbar mobility.Our cross-sectional study included 50 AS patients and 50 controls. Metric measurements and Bath AS indices were measured in AS patients. The distance between C6-C7, T11-T12, and L4-L5 vertebrae was measured, and the difference and percentage of difference between erect position and maximal cervical and lumbar flexion was calculated (T11-T12dif, T11-T12%, L4-L5dif, L4-L5%, T+L dif, T+L%). Intercostal divergence was measured 1.5 cm away on the left from the sternocostal space during maximum inhalation and maximum exhalation, and the difference and percentage of difference between them was calculated (ICdif, IC%).All metric measurements were lower in the AS group except for tragus-to-wall distance. T11-T12dif, T11-T12%, L4-L5dif, T+L dif, and T+L% values were higher in the control group, while other US measurements did not differ between the groups. All US measurements except ICdif and IC% correlated with the Bath AS Metrology Index.Thus, US may be used for assessing spinal mobility in patients with AS. T11-T12dif <0.79 cm may show decreased lumbar sagittal mobility.
我们旨在研究超声（US）是否有助于评估强直性脊柱炎（AS）患者的脊柱活动度和胸廓扩张度，并确定一个用于识别腰椎矢状面活动度降低的临界值。我们的横断面研究纳入了50例AS患者和50例对照。对AS患者进行了测量指标和巴斯强直性脊柱炎指数的测量。测量了C6-C7、T11-T12和L4-L5椎体之间的距离，并计算了直立位与最大颈椎和腰椎前屈位之间的差值及差值百分比（T11-T12差值、T11-T12%、L4-L5差值、L4-L5%、T+L差值、T+L%）。在最大吸气和最大呼气时，于胸骨旁间隙左侧1.5厘米处测量肋间间距，并计算两者之间的差值及差值百分比（IC差值、IC%）。除了耳屏至胸壁距离外，AS组的所有测量指标均较低。对照组的T11-T12差值、T11-T12%、L4-L5差值、T+L差值和T+L%值较高，而其他超声测量指标在两组之间无差异。除IC差值和IC%外，所有超声测量指标均与巴斯强直性脊柱炎测量指数相关。因此，超声可用于评估AS患者的脊柱活动度。T11-T12差值<0.79厘米可能表明腰椎矢状面活动度降低。
