Assessing the flexion of the trunk of patients with camptocormia is a key factor in developing therapies for camptocormia and monitoring their success. Currently used methods to measure this camptocormia angle are based on photographs or short videos. Both methods are not able to take the ability of patients into account to compensate their symptoms for short amounts of time. We propose a simple two sensor measurement setup based on two accelerometers to measure the angle in accordance with the established perpendicular measurement method [1]. We show that our method yields an average deviation of -1.74° with a maximum deviation of +2° and -6° compared to visual assessment with a motion capturing system.
评估脊柱后凸患者躯干的屈曲情况是制定脊柱后凸治疗方案及监测治疗效果的关键因素。目前用于测量脊柱后凸角度的方法是基于照片或短视频。这两种方法都无法考虑到患者在短时间内代偿其症状的能力。我们提出了一种基于两个加速度计的简单双传感器测量装置，以按照既定的垂直测量方法[1]来测量角度。我们的研究表明，与使用运动捕捉系统进行视觉评估相比，我们的方法平均偏差为-1.74°，最大偏差为+2°和-6°。
