A technique for measuring the curvature of the lumbar spine is described and evaluated. Two small electronic inclinometers are attached to the skin overlying the spinous processes of L1 and S1. The signal from these inclinometers is stored and then processed to give a record of lumbar curvature against time. Tests showed that recordings from the inclinometers were reproducible and correlated well (r=0.91) with flexion angles measured from X-rays. The dynamic response of the system was good enough to measure lumbar curvature during typical bending and lifting movements.
本文描述并评估了一种测量腰椎曲率的技术。将两个小型电子倾角仪附着于L1和S1棘突上方的皮肤。来自这些倾角仪的信号被存储起来，然后进行处理，以给出腰椎曲率随时间变化的记录。测试表明，倾角仪的记录具有可重复性，并且与X射线测量的屈曲角度相关性良好（r = 0.91）。该系统的动态响应足以在典型的弯曲和提举动作中测量腰椎曲率。
