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 .
Efficacy of Therapeutic Ultrasound for the Management of Knee Osteoarthritis: A Randomized, Controlled, and Double-Blind Study
Objective The aim of this study was to compare whether the effectiveness of continuous ultrasound ( US ) was superior against pulsed US and against sham US in knee osteoarthritis . Design A r and omized controlled study was carried out on 60 patients diagnosed with knee osteoarthritis according to American College of Rheumatology . The patients were r and omized into the following three treatments : ( 1 ) continuous US ( at a frequency of 1 MHz with intensity of 1 W/cm2 ) , ( 2 ) pulse US ( same frequency and intensity on 1:4 pulse ratio ) , and ( 3 ) sham US . All treatments were applied with 5-cm2 head US device five times a week for 2 weeks in addition to home exercise program including quadriceps isometric exercise , muscle strength exercises , and stretching exercises of the lower extremity muscles for at least three times per week . Assessment s were performed at baseline , at the end of the treatment , and at the end of the treatments and at the sixth month using the following measurements : Western Ontario and McMaster University Osteoarthritis Index – pain , stiffness , function , visual analog scale – pain at rest , visual analog scale – pain on movement , visual analog scale – disease severity , and 20-m walking time . Among these parameters , the Western Ontario and McMaster University Osteoarthritis Index – pain was the primary outcome . Results All groups showed a significant improvement in all parameters in both following visits ( P < 0.05 ) . However , there was no significant difference between the groups . Although the mean reduction percent in Western Ontario and McMaster University Osteoarthritis Index – pain was significantly higher in group I ( continuous US ) when compared to sham group ( 46.5 % vs 28.9 % , P < 0.05 ) at the end of the treatment , this result was not found in other pain parameters . Conclusions The present study demonstrated that all assessment parameters significantly improved in all groups without a significant difference . This result suggested that therapeutic US provided no additional benefit in improving pain and functions in addition to exercise training
