The relative value of nine spinal and thoracic mobility measurements was investigated in 73 male patients with ankylosing spondylitis (AS). The value of a test was obtained by the relative ranks of validity, reliability and sensitivity to change. Validity was determined as age-adjusted correlation of the test result with AS-specific radiological changes in the lumbar spine. Reliability was determined as inter-observer error. Sensitivity to change was determined as change in test result during an intensive rehabilitation course. The five most valuable tests were rotation of the thoracolumbar spine (TR), finger-to-floor distance (FFD), the Schober test, thoracolumbar flexion and occiput-to-wall distance. Of these, FFD had high reliability and sensitivity ranks, but poor correlation with AS-specific spinal changes. TR had high validity and sensitivity ranks, and improvement of the measurement technology would probably result in a superior test for the follow-up of AS. Chest expansion and vital capacity had low ranks in all comparisons.
对73名男性强直性脊柱炎（AS）患者的九项脊柱和胸廓活动度测量的相对价值进行了研究。一项测试的价值通过有效性、可靠性和对变化的敏感性的相对排名来确定。有效性被确定为测试结果与腰椎AS特异性放射学变化的年龄校正相关性。可靠性被确定为观察者间误差。对变化的敏感性被确定为强化康复过程中测试结果的变化。五项最有价值的测试是胸腰椎旋转（TR）、手指触地距离（FFD）、Schober试验、胸腰椎前屈和枕墙距。其中，FFD具有较高的可靠性和敏感性排名，但与AS特异性脊柱变化的相关性较差。TR具有较高的有效性和敏感性排名，测量技术的改进可能会产生一个更优的用于AS随访的测试。在所有比较中，胸廓扩张和肺活量的排名较低。
