前屈对于从搬运物品到铲雪再到农活的许多身体活动都是必不可少的。然而，腰痛是腰椎前屈的常见原因，由于腰椎形状的变化，腰椎间盘承受着沉重的负荷。为了减少腰痛的风险，在本研究中，我们开发了一种运动传感器系统，当腰椎形状改变和骨盆姿势角度改变时，可以通过测量腰椎区域的腰椎来估计腰椎的形状、姿势和负荷。我们提出了该传感器系统的一个可穿戴版本，并提出了一种利用该系统的骨盆姿势角和腰部皮肤曲率来估计腰部形状的方法。此外，我们使用该系统测量了腰椎前屈，并研究了体位变化对腰椎负荷的影响。
Anteflexion is essential for many physical activities ranging from carrying objects through snow shoveling to farm work. However, lumbago is a common cause of anteflexion, in which lumbar disks are under a heavy load due to changes in lumbar spine shape. With the aim to reduce lumbago risk, in this study we developed a motion sensor system that can estimate the shape, posture and load on the lumbar spine from measuring the lumbar in the lumbar region when the lumbar spine shape changes and the pelvis posture angle changes. We present a wearable version of this sensor system, and propose an estimation method of the lumbar shape using the pelvis posture angle and lumbar region skin curvature from this system. In addition, we measure the anteflexion using this system and study the change in load of the lumbar spine caused by changes in posture.
