Shoulder disability questionnaire design and responsiveness of a functional status measure.
The Shoulder Disability Question naire ( SDQ ) is a measure covering 16 items design ed to evaluate functional status limitation in patients with shoulder disorders . The responsiveness of the SDQ was evaluated for 180 patients with soft tissue shoulder disorders , without underlying systemic disorders . These patients participated in a r and omized placebo-controlled trial , in which ultrasound and electrotherapy appeared to be ineffective as adjuvants to st and ardized exercise therapy . At baseline and at 6-week follow-up , patients completed the  SDQ  and rated severity of shoulder pain and their chief complaint , while a research physiotherapist rated severity of symptoms and restriction of mobility . At the 6-week follow-up , patients also rated overall change since baseline . According to the calibrated responsiveness ratio ( CRR ) and the area under the receiver-operator characteristic curve ( AUC ) the SDQ discriminates accurately between self-rated clinical ly stable and improved subjects . The presented results suggest that the SDQ is as responsive as the compared outcome measures , and therefore is ready for use in clinical trials
They have been shown to be valid , reliable , and responsive , with a low administration burden .
