Results 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 .
Conclusions 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 .
Background Recent systematic review s 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 de grade d proprioceptive acuity .
The Fremantle Back Awareness Question naire ( 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 .
Cross-cultural adaptation and validation of the Oxford 12-item knee score in Japanese
Introduction With the high incidence of knee osteoarthritis ( OA ) in Japan , there is a strong need not only for surgical therapies , but also for vali date d outcome measures . For this study , we completed cross-cultural adaptation , testing and validation of the Oxford knee score ( OKS ) for prospect i ve use in national and international clinical studies involving Japanese patients . Material s and methods The Japanese version of the OKS was developed according to the st and ard cross-cultural adaptation guidelines . For validation , the OKS was tested on 54 patients diagnosed with OA , osteonecrosis , ligament or meniscus injury . Reliability was tested using the intraclass correlation coefficient ( ICC ) . Internal consistency or homogeneity was assessed using Cronbach ’s alpha . The correlation between the Japanese OKS , WOMAC and SF-36 question naires was used to assess construct validity . Results No major difficulties were encountered with the translation and pre-testing stages . For reliability and validity , the Japanese OKS was completed without any missed responses by 53 ( 98.15 % ) and 52 ( 96.30 % ) patients at the first and second distribution , respectively . The total OKS showed good reliability with an ICC of 0.85 . Internal consistency was strong ( Cronbach ’s alpha = 0.90 ) . Strong construct validity ( ICC values of 0.51–0.84 ) was obtained against the WOMAC and SF-36 ( physical functioning , role-physical , bodily pain , and social functioning subscales ) scores . Notable “ ceiling ” effects of the OKS were reported for 11 of the 12 question naire items . Conclusion The Japanese OKS has proven to be a reliable and valid instrument for the self- assessment of knee pain and function in Japanese speaking patients with knee OA and other knee complaints
