This study investigated the association between spinal alignment, mobility of the hips and the thoracic spine and low back pain in adolescent cross-country skiers. Cohort of 51 elite cross-country skiers from a cross-country skiing high school in Sweden participated in the study. Sagittal spinal alignment, active range of motion in flexion, extension and rotation of the thoracic spine as well as passive and active extension of the hips were measured. The participants also completed a questionnaire regarding training, competition, skiing technique and occurrence of low back pain. A simple linear regression was calculated to predict pain score based on thoraco-lumbar relation, with a significant (P<0.05) regression equation of y=-0.069x+2.280 (standard error of estimate, 0.034). Participants with greater lordosis than kyphosis were more likely to suffer from low back pain than subjects without this offset. Thoracic mobility and passive or active hip extension showed no correlation with low back pain. Sagittal spinal alignment seems to be related with low back pain among young elite cross-country skiers. This study shows that range of motion of the thoracic spine and hips do not have an effect on the prevalence of low back pain in this population.
本研究调查了青少年越野滑雪运动员脊柱排列、髋部与胸椎活动度和腰痛之间的关联。来自瑞典一所越野滑雪高中的51名精英越野滑雪运动员参与了该研究。测量了矢状面脊柱排列、胸椎屈伸和旋转的主动活动范围以及髋部的被动和主动伸展。参与者还完成了一份关于训练、比赛、滑雪技术和腰痛发生情况的问卷。基于胸腰关系计算了一个简单线性回归来预测疼痛评分，得到一个显著（P<0.05）的回归方程y = -0.069x + 2.280（估计标准误差为0.034）。腰椎前凸大于胸椎后凸的参与者比没有这种偏移的受试者更易患腰痛。胸椎活动度以及髋部的被动或主动伸展与腰痛无相关性。矢状面脊柱排列似乎与年轻精英越野滑雪运动员的腰痛有关。本研究表明，胸椎和髋部的活动范围对该人群腰痛的患病率没有影响。
