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 .
Questionnaire on the perceptions of patients about total knee replacement.
We have developed a 12-item question naire for patients having a total knee replacement ( TKR ) . We made a prospect i ve study of 117 patients before operation and at follow-up six months later , asking them to complete the new question naire and the form SF36 . Some also filled in the Stanford Health Assessment Question naire ( HAQ ) . An orthopaedic surgeon completed the American Knee Society ( AKS ) clinical score . The single score derived from the new question naire had high internal consistency , and its reproducibility , examined by test-retest reliability , was found to be satisfactory . Its validity was established by obtaining significant correlations in the expected direction with the AKS scores and the relevant parts of the SF36 and HAQ . Sensitivity to change was assessed by analysing the differences between the preoperative scores and those at follow-up . We also compared change in scores with the patients ' retrospective judgement of change in their condition . The effect size for the new question naire compared favourably with those for the relevant parts of the SF36 . The change scores for the new knee question naire were significantly greater ( p < 0.0001 ) for patients who reported the most improvement in their condition . The new question naire provides a measure of outcome for TKR that is short , practical , reliable , valid and sensitive to clinical ly important changes over time
