The purpose of this study was to evaluate the limitation of motion as well as comfort provided by four different types of lumbar braces. The four braces were the Raney jacket, the Camp lace-up corset, a molded-polypropylene thoracolumbar-sacral orthosis (TLSO), and a common elastic corset. The data revealed that all braces significantly restrict free lumbar and thoracic motion in the sagittal and frontal planes. All braces restricted lumbar motion more in the frontal than in the sagittal plane. The rigid TLSO and Raney jackets were most restrictive when compared with the Camp corset and the elastic corset. Axial rotation in the lumbar spine is normally minimal and further limitation by a brace would be negligible. All braces restricted thoracic motion despite the fact that lumbar braces were used. The elastic corset was rated the most comfortable and the Raney jacket the least comfortable. This verifies that there is an inverse relationship between a brace's ability to restrict motion and comfort.
本研究的目的是评估四种不同类型的腰部支具所提供的运动限制以及舒适度。这四种支具分别是雷尼夹克式支具、坎普系带式束腹带、模制聚丙烯胸腰骶矫形器（TLSO）和普通弹性束腹带。数据显示，所有支具均显著限制了腰椎和胸椎在矢状面和额状面的自由运动。所有支具在额状面比在矢状面更能限制腰椎运动。与坎普束腹带和弹性束腹带相比，刚性TLSO和雷尼夹克式支具的限制作用最大。腰椎的轴向旋转通常极小，支具对其进一步的限制可忽略不计。尽管使用的是腰部支具，但所有支具均限制了胸椎运动。弹性束腹带被评为最舒适，而雷尼夹克式支具最不舒适。这证实了支具限制运动的能力与舒适度之间存在反比关系。
