Current routine diagnostic procedures for back pain mainly focus on static spinal analyses. Dynamic Surface Topography (DST) is an easy-to-use, radiation-free addition, allowing spine analyses under dynamic conditions. Until now, it is unclear if this method is applicable to back pain patients, and data reports are missing. Within a prospective observational study, 32 patients suffering from thoracic and lumbar back pain were examined while walking, randomized at four speeds (2, 3, 4, 5 km/h), using a DST measuring device (DIERS 4Dmotion Lab). The measurement results were compared with those of a healthy reference group. We calculated the intrasegmental rotation for every subject and summed up the spinal motion in a standardized gait cycle. The Mann-Whitney U Test was used to compare the painful and healthy reference groups at the four different speeds. In a subgroup analysis, the painful group was divided into two groups: one with less pain (≤3 points on the Visual Analogue Scale) and one with more pain (>3 points on the Visual Analogue Scale). The Kruskal-Wallis Test was used to compare these subgroups with the healthy reference group. Of the 32 included patients, not all could walk at the intended speeds (5 km/h: 28/32). At speeds of 2-4 km/h, our results point to greater total segmental rotation of back pain patients compared to the healthy reference group. At a speed of 3 km/h, we observed more movement in the patients with more pain. Overall, we monitored small differences on average between the groups but large standard deviations. We conclude that the DST measuring approach is eligible for back pain patients when they feel confident enough to walk on a treadmill. Initial results suggest that DST can be used to obtain interesting therapeutic information for an individual patient.
目前背痛的常规诊断程序主要集中在静态脊柱分析上。动态表面地形分析（DST）是一种易于使用且无辐射的补充方法，可在动态条件下进行脊柱分析。到目前为止，尚不清楚该方法是否适用于背痛患者，且缺乏数据报告。在一项前瞻性观察研究中，使用DST测量设备（DIERS 4Dmotion Lab）对32名患有胸腰背痛的患者在行走时进行了检查，随机设定了四种速度（2、3、4、5公里/小时）。将测量结果与健康对照组的结果进行了比较。我们计算了每个受试者的节段内旋转，并在标准化步态周期中汇总了脊柱运动。采用曼-惠特尼U检验比较了四个不同速度下的疼痛组和健康对照组。在亚组分析中，疼痛组被分为两组：一组疼痛较轻（视觉模拟评分≤3分），另一组疼痛较重（视觉模拟评分>3分）。采用克鲁斯卡尔-沃利斯检验将这些亚组与健康对照组进行比较。在纳入的32名患者中，并非所有人都能以预期速度行走（5公里/小时：28/32）。在2-4公里/小时的速度下，我们的结果表明，与健康对照组相比，背痛患者的总节段旋转更大。在3公里/小时的速度下，我们观察到疼痛较重的患者运动更多。总体而言，我们监测到各组之间平均差异较小，但标准差较大。我们得出结论，当背痛患者有足够信心在跑步机上行走时，DST测量方法适用于他们。初步结果表明，DST可用于为个体患者获取有趣的治疗信息。
