Recent systematic reviews have demonstrated that pain associated with knee osteoarthritis (OA) is a complex phenomenon that involves various contributors. People with knee OA exhibit symptoms of impaired body-perception, including reduced tactile acuity, impairments in limb laterality recognition, and degraded proprioceptive acuity. The Fremantle Back Awareness Questionnaire (FreBAQ) was developed to assess body-perception specific to the back in people with chronic low back pain. The aim of this study was to develop and assess the psychometric properties of a knee-specific version of the FreBAQ-J (FreKAQ-J), determine whether people with knee pain experience perceptual impairments and investigate the relationship between disturbed self-perception and clinical status.
Sixty-five people with knee OA completed the FreKAQ-J. A subset of the participants completed the FreKAQ-J again two-weeks later. Rasch analysis was used to assess item order, targeting, category ordering, unidimensionality, person fit, internal consistency, and differential item functioning. Validity was investigated by examining the relationship between the FreKAQ-J and clinical valuables.
The FreKAQ-J had acceptable internal consistency, unidimensionality, good test-retest reliability, and was functional on the category rating scale. The FreKAQ-J was significantly correlated with pain in motion, disability, pain-related catastrophizing, fear of movement, and anxiety symptomatology.
We developed FreKAQ-J by modifying the FreBAQ-J. The FreKAQ-J fits the Rasch measurement model well and is suitable for use in people with knee OA. Altered body perception may be worth evaluating when managing people with knee OA.
最近的系统评价表明，与膝关节骨关节炎（OA）相关的疼痛是一种复杂的现象，涉及多种因素。膝关节OA患者表现出身体感知受损的症状，包括触觉敏锐度降低、肢体侧别识别障碍和本体感觉敏锐度下降。弗里曼特尔背部意识问卷（FreBAQ）是为评估慢性下背痛患者背部特定的身体感知而开发的。本研究的目的是开发和评估膝关节特异性版本的FreBAQ-J（FreKAQ-J）的心理测量特性，确定膝关节疼痛患者是否存在感知障碍，并研究自我感知紊乱与临床状况之间的关系。
65名膝关节OA患者完成了FreKAQ-J。一部分参与者在两周后再次完成了FreKAQ-J。采用拉施分析来评估项目顺序、目标定位、类别排序、单维度性、个体拟合度、内部一致性和项目功能差异。通过检查FreKAQ-J与临床指标之间的关系来研究效度。
FreKAQ-J具有可接受的内部一致性、单维度性、良好的重测信度，并且在类别评定量表上功能良好。FreKAQ-J与运动疼痛、残疾、疼痛相关的灾难化、运动恐惧和焦虑症状显著相关。
我们通过修改FreBAQ-J开发了FreKAQ-J。FreKAQ-J很好地拟合了拉施测量模型，适用于膝关节OA患者。在管理膝关节OA患者时，改变的身体感知可能值得评估。
