      STUDY DESIGN: A randomized study.

      OBJECTIVES: To compare muscle strength, cross-sectional area, and density of the back muscles in two categories of patients with chronic low back pain, randomized to either lumbar fusion or cognitive intervention and exercises.

      SUMMARY OF BACKGROUND DATA: In two clinical trials, patients with chronic low back pain plus disc degeneration and postlaminectomy syndrome, respectively, were randomized to either lumbar fusion or cognitive intervention and ...

      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 ...

      STUDY DESIGN: Single blind randomized study.

      OBJECTIVES: To compare the effectiveness of lumbar instrumented fusion with cognitive intervention and exercises in patients with chronic low back pain and disc degeneration.

      SUMMARY OF BACKGROUND DATA: To the authors' best knowledge, only one randomized study has evaluated the effectiveness of lumbar fusion. The Swedish Lumbar Spine Study reported that lumbar fusion was better than continuing physiotherapy and care by the family ...

      The effectiveness of lumbar fusion for chronic low back pain after surgery for disc herniation has not been evaluated in a randomized controlled trial. The aim of the present study was to compare the effectiveness of lumbar fusion with posterior transpedicular screws and cognitive intervention and exercises. Sixty patients aged 25-60 years with low back pain lasting longer than 1 year after previous surgery for disc herniation were randomly allocated to the two treatment groups. ...

      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 ...

      STUDY DESIGN: A reliability study was conducted.

      OBJECTIVE: To estimate measurement errors related to equipment and the observer in computed tomography measurements of cross-sectional area and density of paraspinal muscles. Interobserver reliability was not investigated in the current study.

      SUMMARY OF BACKGROUND DATA: Computer tomography (CT) had been used to measure the cross-sectional area and degeneration of the back muscles in patients with low back pain.

      METHODS: This study ...

      STUDY DESIGN: Translation, cross-cultural adaptation, and validation of a self-report questionnaire.

      OBJECTIVE: To perform a translation and cross-cultural adaptation of the Tampa scale for kinesiophobia (TSK) and to investigate its test-retest reliability, construct validity, and responsiveness among Norwegian-speaking patients with sciatica due to disc herniation.

      SUMMARY OF BACKGROUND DATA: The TSK is a self-report questionnaire developed to assess kinesiophobia, or fear of movement ...

      BACKGROUND: Neck and back pain are common and often account for absenteeism at work. Factors at work as well as fear-avoidance beliefs may influence sick-leave in these patients. The aims of this study were to assess: (1) how sick-listed patients in specialised care perceive demand, control, support, effort, reward, and overcommitment at work compared to a general reference group of workers; (2) if women and men report demand, control, support, effort, reward, and overcommitment ...

      BackgroundEvidence is lacking on whether fat infiltration in the multifidus muscles affects outcomes after total disc replacement (TDR) surgery and if it develops after surgery. The aims of this study were 1) to investigate whether pre-treatment multifidus muscle fat infiltration predicts outcome 2 years after treatment with TDR surgery or multidisciplinary rehabilitation, and 2) to compare changes in multifidus muscle fat infiltration from pre-treatment to 2-year follow-up between the ...

      The objective of the study was to investigate how patients with sciatica due to disc herniation rate the bothersomeness of paresthesia and weakness as compared to leg pain, and how these symptoms are associated with socio-demographic and clinical characteristics. A cross-sectional study was conducted on 411 patients with clinical signs of radiculopathy. Items from the Sciatica Bothersomeness Index (0 = none to 6 = extremely) were used to establish values for paresthesia, weakness and leg ...

      BACKGROUND CONTEXT: Little is known about the prognostic factors for work-related outcomes of sciatica caused by disc herniation.

      PURPOSE: To identify the prognostic factors for return to work (RTW) during a 2-year follow-up among sciatica patients referred to secondary care.

      STUDY DESIGN/SETTING: Multicenter prospective cohort study including 466 patients. Administrative data from the National Sickness Benefit Register were accessed for 227 patients.

      PATIENT SAMPLE: Two samples were ...

      OBJECTIVES: We have previously reported in two randomized controlled trials that cognitive intervention and exercises more effectively improved isokinetic trunk muscle strength than lumbar fusion and postoperative rehabilitation in patients with chronic low back pain. The aim of the present study was to predict changes in muscle strength as regard to changes in pain, function, fear-avoidance beliefs (self-rated questionnaires), changes in cross-sectional area and density of the back ...

      STUDY DESIGN: Testing for trunk muscle strength was performed on 105 patients with chronic low back pain.

      OBJECTIVES: To investigate prediction of isokinetic back muscle strength in patients with low back pain.

      SUMMARY OF BACKGROUND DATA: The clinical evaluation of patients with chronic low back pain often in difficult because of discrepancy between disability and impairment. The isokinetic trunk device was developed as a tool for objective assessment of back muscle strength. However, ...

      BACKGROUND: Few studies have investigated prognostic factors for patients with sciatica, especially for patients treated without surgery. The aim of this study was to identify factors associated with non-success after 1 and 2 years of follow-up and to test the prognostic value of surgical treatment for sciatica.

      METHODS: The study was a prospective multicentre observational study including 466 patients with sciatica and lumbar disc herniation. Potential prognostic factors were ...

      STUDY DESIGN: Cross-sectional study in patients with adolescent idiopathic scoliosis (AIS).

      OBJECTIVES: To evaluate the repeatability, reliability, internal consistency, and concurrent validity (CD) of an adapted Norwegian version of the Scoliosis Research Society 22 questionnaire (SRS-22) and the generic health-related quality of life instrument EuroQol (EQ-5D and EQ-VAS).

      SUMMARY OF BACKGROUND DATA: SRS-22 is widely used for evaluation of health-related quality of life in AIS. Its ...
