This study investigates the clinical course of and prognostic factors for quality of life (Short Form 36 items Health survey (SF-36)) and global perceived effect (GPE) in patients treated for chronic nonspecific low back pain at 5 and 12-months follow-up. Data from a prospective cohort (n ¼ 1760) of …

Chronic non-specific low back pain is assumed to be a multifactorial affliction, implying that a number of different risk factors contribute to its development and persistence. After onset, prognostic factors can potentially predict the future course. Risk factors for the development of chronic pain …

PURPOSE: Patients with chronic Whiplash Associated Disorders (WAD) report symptoms and disability. Neither the relationship between self-reported disability and functional capacity, nor its predictors have been investigated in patients with WAD. This was the purpose of this study. METHOD: This was a …

There is no strong evidence to support the claim that 80% to 90% of patients with low back pain (LBP) become pain-free within 1 month; on average, 62% (range42%–75%) of the patients still experienced back pain after 12 months.1 Studies following patients over a 12-month period have shown that LBP is …

OBJECTIVE: To reach consensus on the most important biopsychosocial factors that influence functional capacity results in patients with chronic nonspecific musculoskeletal pain, arranged in the framework of the International Classification of Functioning, Disability and Health. DESIGN: Three-round, internet-based …

INTRODUCTION: Functional capacity tests are standardized instruments to evaluate patients' capacities to execute work-related activities. Functional capacity test results are associated with biopsychosocial factors, making it unclear what is being measured in capacity testing. An overview of these factors …

The aim of this cross-sectional study was to compare data on the level of aerobic capacity and body composition of nonspecific chronic low back pain (CLBP) patients with normative data matched for sex, age and level of sporting activity. The study population consisted of 101 outpatients with nonspecific …

OBJECTIVE: Change in psychophysical capacity, calculated as the ratio between physical capacity and perceived effort, may be a determinant of change in perceived disability. The aim of this study was to identify determinants for change in perceived disability, as measured with the Roland Morris Disability …

OBJECTIVE: Measurement of exercise capacity is essential in patients with non-specific chronic low back pain (CLBP). However, the conventional Astrand bicycle test is not feasible in patients with a very poor aerobic capacity. Therefore the Astrand bicycles test for non-specific CLBP patients based on …

BACKGROUND AND AIM: Functional Capacity Evaluations (FCEs) are used to quantify physical aspects of work capacity. Safety is a critical issue for clinical use of an FCE. Patients with Chronic Low Back Pain (CLBP) are known to report a temporary increase in pain following an FCE, but it is not known whether …
