Singh DK, Bailey M, Lee R. Biplanar measurement of thoracolumbar curvature in older adults using an electromagnetic tracking device.
To develop a new biplanar method of thoracolumbar curvature measurement by using an electromagnetic tracking device and to study the effects of aging on the thoracolumbar curvature.
Cross-sectional study.
Human movement laboratory.
Healthy (N=52, 26 younger and 26 older) volunteers.
Not applicable.
An electromagnetic tracking device was used to trace the thoracolumbar curvature by recording the positions of the spinous processes of the spine. The coordinates of the curvature were fitted with polynomial equations, and the magnitudes of thoracic kyphosis, lumbar lordosis, and lateral thoracic and lumbar curves were determined.
The present technique was shown to be highly reliable in measuring thoracolumbar curvature with an intraclass correlation coefficient of more than .90. The mean thoracic kyphosis (-46.95 degrees +/-11.41 degrees ) in the older adults was significantly larger than that in the younger adults (-38.82 degrees +/-9.86 degrees ) (P<.01). However, there were no significant differences in lumbar lordosis and lateral curvatures between the 2 subject groups.
The present study provided evidence of an increase in thoracic kyphosis in older adults. The method of measurement presented in this study was found to provide reliable biplanar data that will be useful in a clinical setting.
使用电磁跟踪装置开发一种新的胸腰椎曲率双平面测量方法，并研究年龄对胸腰椎曲率的影响。

电磁跟踪装置通过记录脊柱棘突的位置来追踪胸腰椎曲率。曲率的坐标用多项式方程拟合，确定胸曲、腰曲和侧胸、侧腰曲的大小。
本技术在测量胸腰椎曲率方面具有高度可靠性，组内相关系数大于 0.90。老年人的平均胸曲（-46.95 度+/-11.41 度）明显大于年轻人（-38.82 度+/-9.86 度）（P<.01）。然而，两组间腰椎前凸和侧凸无显著差异。
本研究提供了老年人胸曲增加的证据。本研究中提出的测量方法提供了可靠的双平面数据，在临床环境中很有用。
