Low back pain (LBP) is one of the most prevalent and expensive health care problems in the United States. Studies suggest that stabilization exercise may be effective in the management of people with LBP. To accurately assess the effect of stabilization programs on muscle performance, clinicians need an objective measure that is both valid and reliable. The purpose of this study was to determine whether the double limb lowering test (DLLT) and lower abdominal muscle progression (LAMP) can detect a change in abdominal muscle performance after stabilization exercises. Eleven healthy participants (4 men and 7 women) were randomly assigned to either a specific stabilization exercise (SSE) or general stabilization exercise (GSE) group and were evaluated by the DLLT and LAMP before, during, and at the end of 8 weeks of training. Subjects attended exercise sessions twice per week over 8 weeks. No significant difference in pretest performance existed between the 2 groups. No significant difference was detected with the DLLT for either the SSE or GSE over time or when groups were combined. The LAMP detected a significant difference for the combined groups and GSE but not SSE over time. These data indicate that the LAMP is sensitive to change after a spinal stabilization program, whereas the DLLT does not detect a change after these programs. Furthermore, the GSE was more effective in producing these changes. Additional testing of these assessments is necessary to further validate these tests and to identify specific populations for which these tests may be most appropriate.
下背痛（LBP）是美国最普遍且花费高昂的医疗保健问题之一。研究表明，稳定化训练可能对下背痛患者的管理有效。为了准确评估稳定化训练计划对肌肉性能的影响，临床医生需要一种既有效又可靠的客观测量方法。本研究的目的是确定双下肢下降试验（DLLT）和下腹部肌肉进展测试（LAMP）能否检测出稳定化训练后腹部肌肉性能的变化。11名健康参与者（4名男性和7名女性）被随机分配到特定稳定化训练（SSE）组或一般稳定化训练（GSE）组，并在8周训练前、训练期间和训练结束时通过DLLT和LAMP进行评估。受试者在8周内每周参加两次训练课程。两组在预测试表现上没有显著差异。随着时间的推移，无论是SSE组还是GSE组，单独或合并来看，DLLT均未检测到显著差异。随着时间的推移，LAMP在合并组和GSE组中检测到显著差异，但在SSE组中未检测到。这些数据表明，LAMP对脊柱稳定化训练后的变化敏感，而DLLT在这些训练后未检测到变化。此外，GSE在产生这些变化方面更有效。有必要对这些评估进行额外测试，以进一步验证这些测试，并确定这些测试可能最适合的特定人群。
