Pain related fear and pain intensity have been identified as factors negatively influencing Functional Capacity Evaluation (FCE) performances in patients with CLBP. Conflicting results have been reported in the literature. The objective of this study was to analyze the relationships between pain intensity and pain-related fear on the one hand, and performances during an FCE on the other hand in two samples of patients with chronic low back pain (CLBP).
Two cross sectional observation studies were performed with two samples of patients with CLBP (study 1: n = 79; study 2: n = 58). Pain related fears were operationally defined as the score on the Tampa Scale of Kinesiophobia in study 1, and the Fear Avoidance Beliefs Questionnaire (FABQ) in study 2. Pain intensity was measured with a Numeric Rating Scale in both studies. Avoidance behavior observed during FCE was in both studies operationally defined as the unwillingness to engage in high intensity performance levels of three different functional activities: high intensity lifting, prolonged standing in a forward bend position, and fast repetitive bending at the waist.
A total of 25 correlations between pain and pain related fear, and performance variables were calculated, out of which 7 were significant (p < 0.05). The strength of these significant correlations ranged from r = -0.23 to r = -0.50. Multivariate linear regression analyses revealed non-significant relationships in most instances. Pain and pain related fear contributed little if any to these models.
The relation between pain and pain related fear and FCE performance is weak or non-existent in patients with CLBP.
疼痛相关恐惧和疼痛强度已被确定为对慢性下腰痛（CLBP）患者的功能能力评估（FCE）表现产生负面影响的因素。文献报道的结果相互矛盾。本研究的目的是分析慢性下腰痛（CLBP）患者的两个样本中，一方面疼痛强度与疼痛相关恐惧之间的关系，另一方面FCE期间表现之间的关系。
对两个慢性下腰痛（CLBP）患者样本进行了两项横断面观察研究（研究1：n = 79；研究2：n = 58）。在研究1中，疼痛相关恐惧在操作上被定义为坦帕运动恐惧量表的得分，在研究2中为恐惧回避信念问卷（FABQ）。在两项研究中均使用数字评分量表测量疼痛强度。在FCE期间观察到的回避行为在两项研究中在操作上均被定义为不愿意参与三种不同功能活动的高强度表现水平：高强度举重、在向前弯曲姿势下长时间站立以及腰部快速重复弯曲。
计算了疼痛与疼痛相关恐惧以及表现变量之间总共25个相关性，其中7个具有显著性（p < 0.05）。这些显著相关性的强度范围为r = -0.23至r = -0.50。多变量线性回归分析在大多数情况下显示无显著关系。疼痛和疼痛相关恐惧对这些模型的贡献很小，如果有的话。
慢性下腰痛（CLBP）患者中疼痛与疼痛相关恐惧和FCE表现之间的关系较弱或不存在。
