Innominate movements during hip abduction and external rotation have recently been described in healthy individuals. In the present study the aim was to determine whether these hip movement tests could discriminate altered movement patterns in people with specific pelvic girdle pain (PGP) disorder. This pilot study is the first step in determining the usefulness of prone hip abduction and external rotation in the differential diagnosis of PGP disorders. A cross-sectional comparison between a convenient sample of 6 individuals who had been referred for exercise and advice following diagnosis of ankylosing spondylitis (AS) via a Medical/Rheumatological pathway and 18 healthy age and gender matched controls. Transverse and sagittal plane innominate motion was measured using a palpation and digitizing technique with a magnetic tracking device. Data analysis involved applying best-fit equations to the data and visual inspection of the produced graphs as well as conditional logistical regression for each test position to determine our ability to predict group association. Graphical comparisons demonstrate a distinction between the patients with AS and the healthy controls. Further, for all three hip conditions the innominate angle was a significant predictor of group association (p = 0.002 for AB, p = 0.005 for AB + ER and p = 0.007 for ER).
近期研究发现，健康个体在髋关节外展和外旋时会出现无名骨运动。在本研究中，目的是确定这些髋关节运动测试能否区分患有特定骨盆带疼痛（PGP）疾病的人群中改变的运动模式。这项初步研究是确定俯卧位髋关节外展和外旋在PGP疾病鉴别诊断中有用性的第一步。对通过医学/风湿病学途径诊断为强直性脊柱炎（AS）后被转介接受运动和建议的6名个体的便利样本与18名年龄和性别匹配的健康对照进行横断面比较。使用带有磁跟踪装置的触诊和数字化技术测量横断面上和矢状面上的无名骨运动。数据分析包括对数据应用最佳拟合方程、对生成的图表进行目视检查以及对每个测试位置进行条件逻辑回归，以确定我们预测组关联的能力。图形比较显示了AS患者与健康对照之间的差异。此外，对于所有三种髋关节情况，无名骨角度都是组关联的显著预测因子（外展时p = 0.002，外展 + 外旋时p = 0.005，外旋时p = 0.007）。
