Validity of the SF-36 in patients with morbid obesity.

Background: The Medical Outcome Study 36-Item Short Form Health Survey (SF-36) is one of the most commonly applied generic quality of life instruments. The construct validity of the instrument in patients with morbid obesity is not established.

Participants And Methods: A total of 475 morbidly obese patients (68% women) with a mean (standard deviation) age of 44.

A questionnaire found disease-specific WORC index is not more responsive than SPADI and OSS in rotator cuff disease.

Objectives: To compare responsiveness and minimal clinically important change (MCIC) for the disease-specific Western Ontario Rotator Cuff index (WORC) and the two region-specific questionnaires Shoulder Pain and Disability Index (SPADI) and Oxford Shoulder Scale (OSS) in patients with rotator cuff disease receiving corticosteroid injection therapy.

Study Design And Setting: One hundred twenty-one patients with rotator cuff disease. Western Ontario Rotator Cuff index, SPADI, and OSS were administered before treatment and at 2 and 6 weeks after corticosteroid injection.

Subacromial ultrasound guided or systemic steroid injection for rotator cuff disease: randomised double blind study.

Objective: To compare the effectiveness of ultrasound guided corticosteroid injection in the subacromial bursa with systemic corticosteroid injection in patients with rotator cuff disease.

Design: Double blind randomised clinical trial.

Setting: Outpatient clinic of a physical medicine and rehabilitation department in Oslo, Norway.

Responsiveness of the shoulder pain and disability index in patients with adhesive capsulitis.

Background: Instruments designed to measure the subjective impact of painful shoulder conditions have become essential in shoulder research. The Shoulder Pain and Disability Index (SPADI) is one of the most extensively used scales of this type. The objective of this study was to investigate reproducibility and responsiveness of the SPADI in patients with adhesive capsulitis.

Factor structure of the Shoulder Pain and Disability Index in patients with adhesive capsulitis.

Background: The Shoulder Pain and Disability Index (SPADI) is a self-administered questionnaire that aims to measure pain and disability associated with shoulder disease. It consists of a pain section and a disability section with 13 items being responded to on visual analogue scales. Few researchers have investigated SPADI validity in specified diagnostic groups, although the selection of an evaluative instrument should be based on evidence of validity in the target patient group.

Agreement, reliability and validity in 3 shoulder questionnaires in patients with rotator cuff disease.

Background: Self-report questionnaires play an important role as outcome measures in shoulder research. Having an estimate of the measurement error of these questionnaires is of importance when assessing follow-up results after treatment and when planning intervention studies. The aim of this study was to cross-culturally adapt the Norwegian version of the OSS and WORC questionnaire and examine and compare agreement, reliability and construct validity of the disease-specific shoulder questionnaire WORC with two commonly used shoulder questionnaires, SPADI and OSS, in patients with rotator cuff disease.

Hydrodilatation, corticosteroids and adhesive capsulitis: a randomized controlled trial.

Background: Hydrodilatation of the glenohumeral joint is by several authors reported to improve shoulder pain and range of motion for patients with adhesive capsulitis. Procedures described often involve the injection of corticosteroids, to which the reported treatment effects may be attributed. Any important contribution arising from the hydrodilatation procedure itself remains to be demonstrated.

Range of shoulder motion in patients with adhesive capsulitis; intra-tester reproducibility is acceptable for group comparisons.

Background: Measurements of range of motion play a key role in shoulder research. The purpose of this study is to investigate intra-observer reproducibility of measurements of active and passive range of motion in patients with adhesive capsulitis.

Methods: The study was carried out in a population consisting of 32 patients with clinical signs of adhesive capsulitis.
