磁共振成像（MRI）是一种新的多平面成像技术，可以清晰地显示软组织解剖结构。对26名男性的腰椎进行了扫描。通过横断面扫描，记录腰椎肌肉的位置和横截面积。对这些值与躯干测量和体重进行回归分析。矢状位扫描用于测量腰椎间盘和棘突上覆皮肤的垂直角度。测量每个腰椎间盘相对于两个皮肤点的位置。这些参数可用于下背力的生物力学计算。
Magnetic Resonance Imaging (MRI) is a new multiplanar imaging technique that clearly demonstrates soft tissue anatomy. The lumbar spines of 26 males have been scanned. From the transverse scans, the position and cross-sectional areas of the muscles of the lumbar region were recorded. Regression analysis was performed to relate these values to trunk measurements and body weight. Sagittal scans were used to measure the angles to the vertical of the lumbar discs and of the skin overlying the spinous processes. The position of each lumbar disc relative to two skin points was measured. These parameters can then be used in biomechanical calculations of low-back forces.
