Tape measurement of spinal lateral flexion from the erect posture as the distance the hand moves down the thigh was analysed. Intra- and interobserver reproducibility were found to be acceptable (r=0·74-0·96). Correlations of the measurements with an index of low-back pain and with inclinometric measurements of pelvic, lumbar and thoracic mobility were calculated for 476 patients suffering from low back pain. The correlation coefficients of the tape measurements with the total inclinometric measurements of pelvic and thoracolumbar mobility were 0·63 and 0·64. For spinal mobility alone the corresponding coefficients were 0·48-0·50 for the lumbar spine, and 0·58-0·59 for the thoraco-lumbar spine. The correlation coefficients between the method using tape measurement and the index of low back pain were -0·23 and -0·25 (P<0·001). Lateral flexion of the lumbar spine alone, measured inclinometrically, had correlation coefficients of -0·11 and -0·17 (P<0·05 and 0·001) with low back pain. According to the inclinometric measurements, pelvic and thoracic spinal mobility were also related to the degree of low back pain, which probably improves further on the tape measurement method as an indicator of low back disability.
分析了从直立姿势开始脊柱侧屈的卷尺测量结果，即手沿大腿向下移动的距离。观察者内和观察者间的可重复性被认为是可接受的（r = 0·74 - 0·96）。对476名腰痛患者计算了这些测量值与腰痛指数以及骨盆、腰椎和胸椎活动度的倾角测量值之间的相关性。卷尺测量值与骨盆和胸腰椎活动度的总倾角测量值的相关系数分别为0·63和0·64。仅就脊柱活动度而言，腰椎的相应系数为0·48 - 0·50，胸腰椎的相应系数为0·58 - 0·59。使用卷尺测量的方法与腰痛指数之间的相关系数为 -0·23和 -0·25（P < 0·001）。仅通过倾角测量的腰椎侧屈与腰痛的相关系数分别为 -0·11和 -0·17（P < 0·05和0·001）。根据倾角测量，骨盆和胸椎的活动度也与腰痛程度相关，作为腰痛残疾指标的卷尺测量方法可能会进一步改善这种情况。
