The purpose of this study was to correlate low-back complaints in 64 female gymnasts (mean age, 12 years) to spinal sagittal configuration and mobility as measured by two noninvasive methods. Measurements by Debrunner's kyphometer and Myrin's inclinometer were highly correlated. Average thoracic kyphosis was 32 degrees, lumbar lordosis 35 degrees. The mean range of sagittal motion was 57 degrees in the thoracic spine and 113 degrees in the lumbar spine. On average, 1 degree of the total sagittal lumbar mobility was lost for every 1 degree of increased lordosis. Low-back pain (LBP) was reported by 20% of the girls, and these girls had a significantly larger lordosis (41 degrees) than girls with no history of LBP (35 degrees).
本研究的目的是通过两种非侵入性方法，将64名女性体操运动员（平均年龄12岁）的下背部不适与脊柱矢状面形态和活动度相关联。使用德布勒纳测角器和梅林倾角仪所做的测量结果高度相关。平均胸椎后凸为32度，腰椎前凸为35度。矢状面活动的平均范围在胸椎为57度，在腰椎为113度。平均而言，腰椎前凸每增加1度，腰椎矢状面总活动度就会丧失1度。20%的女孩报告有下背部疼痛（LBP），这些女孩的前凸（41度）明显大于无LBP病史的女孩（35度）。
