The aim of this study was to determine whether graded activity restored occupational function in industrial blue-collar workers who were sick-listed for 8 weeks because of subacute, nonspecific, mechanical low back pain (LBP). Patients with LBP, who had been examined by an orthopedic surgeon and a social worker, were randomly assigned to either an activity(More)
A longitudinal, prospective study was conducted on 3,020 aircraft employees to identify risk factors for reporting acute back pain at work. The premorbid data included individual physical, psychosocial, and workplace factors. During slightly more than 4 years of follow-up, 279 subjects reported back problems. Other than a history of current or recent back(More)
The authors prospectively evaluated 3020 volunteers of the Boeing-Everett plant to assess risk factors that predispose workers to file industrial back injury claims. During four years of follow-up observation, more than 279 subjects reported acute back problems. The effect of the only predictive physical variable was explainable by a history of medical(More)
Issues underlying the rapid increase in assignment of disability to nonspecific low back pain are addressed. The central point of the discussion is that the healthcare system relies too exclusively on a biomedical perspective on pain and illness while failing to consider adequately environmental influences on symptom behavior and care seeking.

OBJECTIVE To estimate the importance and implications of placebo effects in pain treatment and research from the existing literature, with emphasis on their magnitude and duration, the conditions influencing them, and proposed explanations. DATA SOURCES English-language articles and books identified through MEDLINE (1980 through 1993) and PsycLIT (1967(More)
Common criticisms of behavioral treatment programs for chronic pain are summarized. Some criticisms are based on conceptual misunderstandings; therefore, basic concepts and goals of behavioral programs are presented. Other criticisms question the effectiveness of these programs; therefore, the role of social reinforcers in maintaining or reducing pain(More)
Back-pain patients with onset in the preceding 1–10 days and comparable on a back examination were randomly assigned to traditional management (A regimen) and behavioral treatment methods (B regimen). Patients were compared at 6 weeks and 9–12 months on a set of “Sick/Well” scores derived from patient reported vocational status (V), health-care utilization(More)
Pain is reconceptualized in learning-based behavioral terms. Methods to assess behavioral elements of pain and to discuss nonmedical influences on pain with patients as well as behaviorally based tactics for early and long-term management and reactivation are discussed in this article.
