下背痛是指下背部的疼痛，通常是指背部肋骨下缘以下的部分，由于好发于第四和第五腰椎或第五腰椎和第一腰椎间，也有不少人称之为“腰痛”。有关下背痛的的治疗效果一直缺乏有效和客观的测量方法，基于脊柱肌肉功能和结构特征，本文将重点讨论核心稳定性与核心力量的提出，核心肌群的确定与分类，核心稳定肌群与下背痛的联系，并探讨训练运动疗法在提高核心力量方面的特点、作用。人体核心最主要的区域是由腰、骨盆、髋关节3部分围构而成，核心稳定性训练可有效稳固脊柱并起到传递力量作用。如何通过训练提高核心力量继而减轻腰背疼痛，同时针对其疗效进行有效的评价的将是今后研究的重点。

Lower back pain refers to the pain in the lower back. It usually refers to the region below the lower costal margin on the back. The pain mostly occurs on L4 and L5, or L5 and L1, which is usually called as lower back pain. For the treatment of low back pain, it has lacked the effective and objective measurement methods based on the functional and structural features of spinal muscles. This article discussed on the core stability and core strength, the identification and classification of core muscle group, the relation between core stabilizing muscle group and low back pain. It also discussed the characteristics and effects of training motion therapy in the improving of core strength. The core of human body was consisted of waist, pelvis and hip joint. Core stabilizing training can effectively stabilize the spine and transmit power. The question of how to train and improve the core strength to relieve low back pain and make effective evaluation according to its therapeutic results are the key points in the future study.
