Population-based, prospective cohort. ⋯ Most new and recurrent LBP episodes are mild. Less than one third of cases resolve annually, and more than 20% recur within 6 months. LBP episodes are more recurrent and persistent in older adults.

Randomized Controlled Trial Multicenter Study Comparative Study
Psychometric properties of the functional rating index in patients with low back pain.
The purpose of this study was to validate the psychometric properties of the functional rating index (FRI), establish the instrument's minimum clinically important difference (MCID), and compare its psychometric properties with the Oswestry questionnaire. ⋯ The FRI is less reliable than the Oswestry but appears to have comparable validity and responsiveness. Before the FRI can be recommended for widespread use in patients with neck and low back pain, it should be further tested in patients with neck pain.

Comparative Study
Physicians' initial management of acute low back pain versus evidence-based guidelines. Influence of sciatica.
Little information is available on physician characteristics and patient presentations that may influence compliance with evidence-based guidelines for acute low back pain. ⋯ A majority of primary care physicians continue to be noncompliant with evidence-based back pain guidelines. Sciatica dramatically influenced clinical decision-making, increasing the extent of noncompliance, particularly for internal medicine and family practice. Physicians' misunderstanding of sciatica's natural history and belief that more intensive initial management is indicated may be factors underlying the observed influence of sciatica.

Comparative StudyCritical comparison of nine different self-administered questionnaires for the evaluation of disability caused by low back pain.
The aim of this study was to critically compare 9 self-administered questionnaires designed to evaluate disability caused by back pain. ⋯ On the basis of psychometric evaluations as well as feasibility considerations, the authors suggest using either the Roland-Morris or Oswestry questionnaire as the best assessment of the level of disability caused by back pain.

Previous research supports the fear-avoidance model in explaining chronic low back pain (LBP) disability. The aims of the present study were to determine: (1) whether fear-avoidance model variables are associated already during acute stages of LBP and (2) whether (increases in) pain-related fear are associated with other patient characteristics routinely assessed by the General Practitioner (GP). General practice patients consulting because of a new episode of LBP completed questionnaires on pain-related fear, avoidance, pain and disability. ⋯ Pain-related fear was slightly higher in patients reporting low job satisfaction and in those taking bedrest. These results suggest that the fear-avoidance model as it was developed and tested in chronic LBP, might not entirely apply to acute LBP patients. Future research should focus on the transition from acute to chronic LBP and the shifts that take place between fear-avoidance model associations.
