Thoracic kyphosis angle measurements using surface topography with ISIS2 were carried out to estimate the inherent variability in the parameter caused by natural change in the patient's stance, breathing and muscle tension. A mean kyphosis angle of 33.8 degrees (sd 13.4 degrees , range 6 degrees -66 degrees ) was measured from repeat tests on 61 patients. The mean difference between the pairs of measurements was -0.02 degrees (sd 3.18 degrees ) and the 95% tolerance limits were -7.41 degrees to 7.38 degrees . This variability is lower than the clinically significant change in kyphosis angle reported in the literature. Thus kyphosis angle in ISIS2 is suitable for monitoring progress in kyphotic deformities.
采用ISIS2表面地形测量法进行胸椎后凸角测量,以评估因患者姿势、呼吸和肌肉张力的自然变化而导致该参数的固有变异性。对61例患者进行重复测试,测得平均后凸角为33.8度(标准差13.4度,范围6度至66度)。测量值对之间的平均差值为-0.02度(标准差3.18度),95%的容许限为-7.41度至7.38度。这种变异性低于文献报道的后凸角临床上的显著变化。因此,ISIS2中的后凸角适用于监测脊柱后凸畸形的进展情况。
