Spinal loading in excessive and repeated trunk flexion may hinder recovery from acute low back pain. The Spineangel device provides real-time patient biofeedback on trunk flexion and may facilitate recovery from lower back injury. This cross-sectional study evaluates validity and reliability of this device in the laboratory setting. Participants included 18 healthy males. Angular displacements were simultaneously obtained from a Spineangel device placed on the hip and criterion measures of hip, lumbar and total sagittal rotation, and pelvic tilt obtained via 3D Motion Analysis. Each participant repeated four movements five times in a random order (forward bending fingertips-to-knees and to mid-lower leg, full flexion, and full extension). Intraclass correlation coefficients (ICC) for Spineangel measurement of trunk motion were excellent (ICC>0.9). The coefficient of repeatability was less than 5.2 degrees in both flexion and extension. Spineangel showed the highest correlation with Motion Analysis((R)) measurement of pelvic tilt with no statistical difference between measures when bending forward to fingertips-to-knees. Given its high reliability, the Spineangel device has potential as a trunk flexion biofeedback device. Further investigation is required to see if these laboratory results can be reproduced in the clinical setting and to determine the clinical benefits of such a device.
过度且重复的躯干前屈时的脊柱负荷可能会阻碍急性下背痛的恢复。Spineangel设备可提供关于躯干前屈的实时患者生物反馈，可能有助于下背部损伤的恢复。这项横断面研究评估了该设备在实验室环境中的有效性和可靠性。参与者包括18名健康男性。通过放置在髋部的Spineangel设备同时获取角位移，并通过三维运动分析获得髋部、腰椎和总矢状面旋转以及骨盆倾斜的标准测量值。每位参与者以随机顺序重复进行四个动作各五次（指尖触膝和触小腿中部的前屈、完全屈曲和完全伸展）。Spineangel测量躯干运动的组内相关系数（ICC）极佳（ICC>0.9）。屈伸时的重复性系数均小于5.2度。Spineangel与运动分析测量的骨盆倾斜度相关性最高，向前弯曲至指尖触膝时测量值之间无统计学差异。鉴于其高可靠性，Spineangel设备有潜力成为一种躯干前屈生物反馈设备。需要进一步研究以确定这些实验室结果能否在临床环境中重现，以及确定该设备的临床益处。
