这项研究考察了疼痛灾变和疼痛相关恐惧在多大程度上解释了膝骨性关节炎(OA)患者的疼痛、心理残疾、身体残疾和行走速度。这项研究的参与者是106名被诊断为至少一个膝盖有骨关节炎的人，他们报告说膝盖疼痛持续了六个月或更长时间。结果表明，疼痛灾变可以解释疼痛(部分R2[Pr2]=0.10)、心理残疾(Pr2=0.20)、身体残疾(Pr2=0.11)以及正常(Pr2=0.04)、快速(Pr2=0.04)和中速(Pr2=0.04)步态速度的差异(均P‘s≤0.05)。与疼痛相关的恐惧解释了心理残疾(PR2=0.07)和快速行走(PR2=0.05)测量结果差异的很大比例。疼痛认知，尤其是疼痛灾变，似乎是了解膝骨性关节炎患者疼痛、残疾和正常、快速和中速行走的重要变量。对了解这一人群中疼痛和残疾的差异感兴趣的临床医生可能会受益，方法是将他们的调查重点从传统的医学和人口统计学变量扩大到包括对疼痛、灾难和疼痛相关恐惧的评估。
This study examined the degree to which pain catastrophizing and pain-related fear explain pain, psychological disability, physical disability, and walking speed in patients with osteoarthritis (OA) of the knee. Participants in this study were 106 individuals diagnosed as having OA of at least one knee, who reported knee pain persisting six months or longer. Results suggest that pain catastrophizing explained a significant proportion (all P's ≤ 0.05) of variance in measures of pain (partial r2 [pr2] = 0.10), psychological disability (pr2 = 0.20), physical disability (pr2 = 0.11), and gait velocity at normal (pr2 = 0.04), fast (pr2 = 0.04), and intermediate speeds (pr2 = 0.04). Pain-related fear explained a significant proportion of the variance in measures of psychological disability (pr2 = 0.07) and walking at a fast speed (pr2 = 0.05). Pain cognitions, particularly pain catastrophizing, appear to be important variables in understanding pain, disability, and walking at normal, fast, and intermediate speeds in knee OA patients. Clinicians interested in understanding variations in pain and disability in this population may benefit by expanding the focus of their inquiries beyond traditional medical and demographic variables to include an assessment of pain catastrophizing and pain-related fear.
