Non-specific low back pain represents 90-95% of all cases of low back pain and it has a prevalence of 18% in the adult population, assuming a great socioeconomic impact. The main objective of this observational case-control study study is to evaluate if there are differences in the simultaneous contraction of the core muscles between nonspecific low back pain and healthy subjects. This study will be carried out in the Physiotherapy department of the University of Alcalá. Eighty-two participants <18 years old, will be recruited, paired with NSLBP (n = 41) and healthy (n = 41). The main outcome will be the onset muscle contraction of lateral abdominal wall (internal oblique, external oblique and transversus abdominis), pelvic floor, lumbar multifidus and respiratory diafragm. The maneuvers that the subjects will perform will be abdominal drawing in maneouver, contralateral arm lift, valsalva, and voluntary pelvic floor contraction in sitting and standing. As a secondary objective, to analyze the amount of contraction of each muscle group and the capacity of the diaphragms to be excreted in both groups of subjects. Finally, to relate pain and disability.
非特异性下背痛占所有下背痛病例的 90-95%，在成年人群中的患病率为 18%，假设其具有重大的社会经济影响。本观察性病例对照研究的主要目的是评估非特异性下背痛患者和健康受试者的核心肌群是否存在同时收缩的差异。这项研究将在阿尔卡拉大学的物理治疗系进行。将招募 82 名年龄小于 18 岁的参与者，与非特异性下背痛患者（n = 41）和健康受试者（n = 41）进行配对。主要结果将是侧腹壁（内斜肌、外斜肌和横腹肌）、盆底、腰椎多裂肌和呼吸横膈膜的起始肌肉收缩。受试者将进行的动作有腹部牵引动作、对侧手臂抬起、valsalva 动作和坐立位时的自愿盆底收缩。作为次要目标，分析每组肌肉群的收缩量以及两组受试者膈肌的呼气能力。最后，将疼痛和残疾联系起来。
