This study was designed to find out the relationship between the multiplied linear dimensions (MLD) measurement and the cross-sectional area (CSA) measurement of the lumbar multifidus muscle.
Sixty healthy female subjects participated in this study. The CSA of the lumbar multifidus muscle from L2 to L5 was bilaterally measured by tracing around the muscle margins with an on- screen cursor. The linear dimensions including lateral dimension (LD), anteroposterior dimension (APD) and MLD of the muscles were also calculated at the same levels of lumbar vertebrae.
The linear regression between CSA and MLD for each vertebral level was significant (r=0.89 to 0.97, p<0.0001). In addition, there was significant correlation between CSA and APD (r=0.69 to 0.87, p<0.05).
MLD method can be used to predict the CSA of the lumbar multifidus muscle. The method described for assessing the multifidus muscle is a potentially valuable, quick and easy way to evaluate muscle size at different levels of the lumbar vertebrae in clinical practice.
本研究旨在探究腰椎多裂肌的倍增线性尺寸（MLD）测量值与横截面积（CSA）测量值之间的关系。
60名健康女性受试者参与了本研究。通过在屏幕上用光标沿着肌肉边缘描绘，双侧测量从L2至L5的腰椎多裂肌的CSA。同时，在相同腰椎水平计算肌肉的线性尺寸，包括横向尺寸（LD）、前后尺寸（APD）和MLD。
每个椎体水平的CSA与MLD之间的线性回归具有显著性（r = 0.89至0.97，p < 0.0001）。此外，CSA与APD之间存在显著相关性（r = 0.69至0.87，p < 0.05）。
MLD方法可用于预测腰椎多裂肌的CSA。所描述的评估多裂肌的方法是临床实践中评估不同腰椎水平肌肉大小的一种潜在有价值、快速且简便的方法。
