Low back pain is the leading cause of disability and expense from work-related conditions in the United States. Forty percent of the expense of the worker's compensation program is spent on claims involving the low back. There are several systems of impairment evaluation in use in the United States, but the most commonly used has been developed by the American Medical Association. Evaluation of impairment related to the low back is expressed as a percent impairment of the whole person and is calculated by combining values related to: (1) diagnostic based categories, (2) range of motion of the spine, and (3) neurologic deficits in the lower extremities. Using this system, and given a cooperative patient, a reproducible quantification of impairment can be obtained to help administrators of the worker's compensation system more fairly compensate injured workers for partial permanent disability.
在美国，腰痛是导致与工作相关疾病所致残疾和费用的主要原因。工人赔偿计划40%的费用用于涉及腰部的索赔。美国使用多种损伤评估系统，但最常用的是由美国医学协会开发的系统。与腰部相关的损伤评估以整个人体的损伤百分比表示，通过结合以下方面的值来计算：（1）基于诊断的类别，（2）脊柱活动范围，以及（3）下肢神经功能缺损。使用该系统，在患者配合的情况下，可以获得可重复的损伤量化结果，以帮助工人赔偿系统的管理人员更公平地补偿受伤工人的部分永久性残疾。
