To properly evaluate residual permanent disability arising from impairment of the spine, it is essential to conduct a careful and complete examination in order to arrive at a diagnosis and a determination that present findings are unlikely to change. A formula for computation of permanent disability as developed by McBride includes functional deficiency and physical disorders, taking into account 12 variables. This formula can be simplified to seven components if the physical disorders are mentally computed into the factors of quickness of action, coordination, strength, security, endurance, safety, and adverse employability, which are given weighted values. This method can provide a valid determination of percentage of disability. Some situations only require a delineation of the impairment present and defer disability determination to an agency or board. Currently, there is a trend toward equating the amount of disability with the loss of earnings, which is quite contrary to the longstanding, traditional view.
为了正确评估因脊柱损伤导致的残余永久性残疾，必须进行仔细而全面的检查，以便做出诊断，并确定当前的检查结果不太可能改变。麦克布莱德提出的永久性残疾计算方法包括功能缺陷和身体疾病，其中考虑了12个变量。如果将身体疾病在心理上计算到行动速度、协调性、力量、安全感、耐力、安全性和就业不利因素中，并赋予这些因素加权值，该公式可简化为七个组成部分。这种方法可以有效地确定残疾百分比。有些情况只需要描述存在的损伤，并将残疾评定推迟给某个机构或委员会。目前，有一种将残疾程度与收入损失等同起来的趋势，这与长期以来的传统观点大相径庭。
