In order to accurately assess the abdominal muscles, clinicians need valid clinical measures. The double leg lowering test (DLLT) and lower abdominal muscle progression (LAMP) are two common tests of abdominal muscle performance. The purposes of this study were to determine the relation between surface electromyographic (EMG) activity during the DLLT and LAMP levels; hip joint resultant moments and DLLT and LAMP levels; and the two measures of DLLT and LAMP.
Ten healthy participants were tested under both conditions. Surface EMG activity of the abdominal muscles was obtained, while pelvic movement was detected simultaneously.
A moderate to strong association was found between rectus abdominus muscle activity and a moderate association with the external obliques with both test levels. For the internal oblique/transversus abdominus, a moderate and weak association was found with the DLLT and LAMP, respectively. A very strong association existed between the hip resultant joint moments (RJM) and the DLLT, while there was a weak correlation between hip RJM and the LAMP. No significant correlation was found between the DLLT and LAMP grades.
This finding suggests that these tests may measure different qualities of muscle performance and provides preliminary support for their use. Further evaluation of these assessments with clinical populations is necessary.
为了准确评估腹部肌肉，临床医生需要有效的临床测量方法。双腿下降试验（DLLT）和下腹部肌肉进展试验（LAMP）是两种常见的腹部肌肉功能测试。本研究的目的是确定DLLT期间的表面肌电图（EMG）活动与LAMP水平之间的关系；髋关节合力矩与DLLT和LAMP水平之间的关系；以及DLLT和LAMP的两种测量方法之间的关系。
对10名健康参与者在两种情况下进行测试。获取腹部肌肉的表面肌电图活动，同时检测骨盆运动。
在两种测试水平下，腹直肌活动之间发现中度至强关联，与腹外斜肌存在中度关联。对于腹内斜肌/腹横肌，分别与DLLT和LAMP发现中度和弱关联。髋关节合力矩（RJM）与DLLT之间存在非常强的关联，而髋关节RJM与LAMP之间存在弱相关性。DLLT和LAMP等级之间未发现显著相关性。
这一发现表明这些测试可能测量肌肉功能的不同质量，并为其使用提供了初步支持。有必要对临床人群进行这些评估的进一步评价。
