BACKGROUND AND PURPOSE Clinicians treating patients with low back pain often use exercise to reduce pain and improve function. The aim of this study was to evaluate the effectiveness of trunk extensor endurance training in reducing pain and decreasing disability in subjects with subacute low back pain (ie, onset of back pain within 7 days to 7 weeks). SUBJECTS AND METHODS Patients were random...

To determine the reliability and concurrent validity of a visual analogue scale (VAS) for disability as a single-item instrument measuring disability in chronic pain patients was the objective of the study. For the reliability study a test-retest design and for the validity study a cross-sectional design was used. A general rehabilitation centre and a university rehabilitation centre was the se...

BACKGROUND The choice of an evaluative instrument has been hampered by the lack of head-to-head comparisons of responsiveness and the minimal clinically important difference (MCID) in subpopulations of low back pain (LBP). The objective of this study was to concurrently compare responsiveness and MCID for commonly used pain scales and functional instruments in four subpopulations of LBP patient...

By using a population-based cohort of the general Dutch population, the authors studied whether an excessively negative orientation toward pain (pain catastrophizing) and fear of movement/(re)injury (kinesiophobia) are important in the etiology of chronic low back pain and associated disability, as clinical studies have suggested. A total of 1,845 of the 2,338 inhabitants (without severe diseas...

Most pain and disability variance in patients with low back pain still remains unexplained. The aim of this study was to enhance the degree of explained variance by including measures of pain and tactile sensitivity as well as pain-related endurance and fear-avoidance responses. Thirty-six post lumbar disc surgery patients completed psychometric questionnaires (Avoidance-Endurance Questionnaire...

BACKGROUND Psychological factors are important mediators of the differences between impairment and disability. The most commonly used measures of disability and psychological factors are lengthy and are usually administered as paper questionnaires. The aim of this study was to assess the correlation between perceived disability and psychological factors with use of the user-friendly, web-based ...

OBJECTIVE The causes of low back pain in China and Western countries are extremely different. We attempted to analyze the risk factors of low back pain in urban and rural patients under the dual economy with the simplified Chinese version of Roland-Morris disability questionnaire (SC-RMDQ) to demonstrate that SC-RMDQ could evaluate patients with low back pain arising from different causes. ME...

CONTEXT Chronic pain is common in primary care patients and is associated with distress, disability, and increased health care use. OBJECTIVE To assess whether a collaborative intervention can improve chronic pain-related outcomes, including comorbid depression severity, in a Department of Veterans Affairs primary care setting. DESIGN, SETTING, AND PARTICIPANTS Cluster randomized controlled...

BACKGROUND AND PURPOSE The purpose of this randomized controlled trial was to examine the usefulness of the addition of specific stabilization exercises to a general back and abdominal muscle exercise approach for patients with subacute or chronic nonspecific back pain by comparing a specific muscle stabilization-enhanced general exercise approach with a general exercise-only approach. SUBJEC...

OBJECTIVES Compensable injury increases the likelihood of having persistent pain after injury. Three-quarters of patients report chronic pain after traumatic injury, which is disabling for about one-third of patients. It is important to understand why these patients report disabling pain, in order to develop targeted preventative interventions. This study examined the experience of pain and dis...
