Background: The process of returning disabled workers to work presents numerous challenges. In spite of the growing evidence regarding work disability prevention, little uptake of this evidence has been observed. One reason for limited dissemination of evidence is the complexity of the problem, as it is subject to multiple legal, administrative, social,(More)
Although information exists on the cost of workers' compensation low back pain (LBP), there is limited information on the duration of lost work time as well as the association between cost and duration. For this study, cost and duration of lost work time information were derived from a large workers' compensation company's database for 1992 LBP claims (n =(More)
STUDY DESIGN Retrospective cohort study. OBJECTIVES Practical evaluation of a rapid prognostic screening method to predict length of disability after acute occupational low back pain (OLBP). SUMMARY OF BACKGROUND DATA Few studies have evaluated the prognostic value of administrative data and selected clinical variables in typical practice settings. (More)
OBJECTIVE To examine early magnetic resonance imaging (MRI) utilization for workers compensation cases with acute, disabling low back pain and further, to examine low or high propensity to undergo early MRI with disability duration, medical costs, and surgery. METHODS Two-year follow-up of 3264 cases. Cox regression and generalized linear models were used(More)
Work-related low-back disorders (LBDs) continue to be one of the single largest sources of compensation costs. The relative contributions of personal, workplace, organizational, and environmental variables to the development and severity of LBDs are not completely understood. The inclusion of personal variables in epidemiologic studies of LBDs has been(More)
The purpose of this experiment was to investigate the feasibility of using psychophysical methods to determine maximum acceptable forces for various types and frequencies of repetitive wrist motion. Four adjustable work stations were built to simulate repetitive wrist flexion with a power grip, wrist flexion with a pinch grip, and wrist extension with a(More)
STUDY DESIGN Retrospective analysis of administrative claims data in a single workers' compensation jurisdiction. OBJECTIVES To evaluate the effects of alternative definitions and follow-up parameters on rates of low back pain recurrence based on detailed administrative data. SUMMARY OF BACKGROUND DATA Previous studies reported low back pain recurrence(More)
Recurrences of low back pain (LBP) have been shown to be both frequent and costly, with reported recurrence rates ranging from 5 to 82%. Numerous methodological approaches have been developed to identify recurrence but there has been no standardized definition of LBP recurrence or required follow-up time. The objective of this study was to compare the(More)
Setting priorities for workplace health and safety research depends upon accurate and reliable injury and illness data. All occupational health databases have limitations when used to summarize the national scope of workplace hazards. The comparison of data from multiple sources may produce more credible estimates of the leading occupational injuries and(More)
Previously published epidemiologic studies of low back pain (LBP) have reported that the prevalence of low back disability has increased dramatically. These studies based their findings on either the number of disability claims filed, the disability duration, or both. This information was from countries other than the United States or from the US Social(More)
