An inception cohort design was used to study a consecutive sample of back-injured workers. ⋯ The Vermont Disability Prediction Questionnaire is a brief, easily administered and scored tool for identifying back-injured workers at relative risk for chronic disability. Such early identification should increase the efficiency of disability prevention strategies by directing them toward people who need them most. The accuracy of the questionnaire needs to be tested in a variety of different clinical and socioeconomic settings.

Randomized Controlled Trial Comparative Study Clinical Trial
Responsiveness of functional status in low back pain: a comparison of different instruments.
This study compares the responsiveness of three instruments of functional status: two disease-specific questionnaires (Oswestry and Roland Disability Questionnaires), and a patient-specific method (severity of the main complaint). We compared changes over time of functional status instruments with pain rated on a visual analog scale. Two strategies for evaluating the responsiveness in terms of sensitivity to change and specificity to change were used: effect size statistics and receiver-operating characteristic method. ⋯ The sensitivity to change of the rating of Oswestry Questionnaire was lower than that of the other instruments. The main complaint was not very specific to change. The two strategies for evaluating the responsiveness were very useful and appeared to complement each other.

Low back pain (LBP) is a common problem that is costly in both financial and human terms. The impact of LBP on an individual varies greatly. For some, LBP is a minor inconvenience; but for others LBP is associated with significant disability and with psychosocial dysfunction for the individual and for the family. ⋯ Once LBP has occurred, the impact of the LBP on the individual and the family is influenced by the health-beliefs and coping strategies of the individual and the family. Distress appears to be secondary to physical restriction rather than pain, but the distress may aggravate the pain and thus the disability. The paper concludes with a discussion of the impact of health practitioners on pain-related disability.

Review
Functional restoration. Returning patients with chronic low back pain to work--revolution or fad?
A review was performed to assess the basis for functional restoration programs in returning patients with chronic low back pain to work. ⋯ Further clinical trials based on sound methodology are needed.

The Roland-Morris Questionnaire (RMQ) is a self-administered disability measure in which greater levels of disability are reflected by higher numbers on a 24-point scale. The RMQ has been shown to yield reliable measurements, which are valid for inferring the level of disability, and to be sensitive to change over time for groups of patients with low back pain. Little is known about the usefulness of this instrument in aiding decision making regarding individual patients. The purpose of this study was to determine the minimum level of detectable change when the RMQ is applied to individual patients. ⋯ The magnitude of CSEMs is sufficiently small to detect change in patients with initial scores in the central portion of the scale (4-20 RMQ points); however, the magnitude is too large to detect improvement in patients with scores of less than 4 and deterioration in patients who have scores greater than 20.
