Purpose
The objective of this study was to evaluate the effects of an exercise program focusing on muscle stretching and endurance training on the 12-month incidence of low back pain (LBP) in office workers.Methods
A 12-month prospective cluster-randomized controlled trial was conducted in healthy office workers with lower-than-normal trunk extension flexibility or trunk muscle endurance. Healthy office workers (n = 563) were randomly assigned at the cluster level into either intervention (n = 282) or control (n = 281) groups. Participants in the intervention group received an exercise program that included daily stretching exercise and twice-a-week muscle endurance training. Those in the control group received no intervention. The 12-month incidence of LBP was the primary outcome. Secondary outcome were pain intensity, disability level, and quality of life and health status. Analyses were performed using the Cox proportional hazard models.Results
Over the 12-month follow-up, 8.8 % of participants in the intervention group and 19.7 % in the control group developed incidence of LBP. Hazard rate ratios showed a protective effect of the exercise program for LBP (HR = 0.37, 95 % CI 0.22–0.64) after adjusting for biopsychosocial factors. There was no significant difference in pain intensity, disability, and quality of life and health status between those who reported incidence of LBP in the intervention and control groups.Conclusion
An exercise program consisting of muscle stretching and endurance training is an effective intervention to reduce incident LBP for office workers with lower-than-normal trunk extension flexibility or trunk muscle endurance. 相似文献2.

Objective
The purpose of this study was to develop a conceptual model for the association between various biopsychosocial factors and nonspecific low back pain (LBP) in a sample of office workers.Methods
A 1-year prospective cohort study of 669 healthy office workers was conducted. At baseline, a self-administered questionnaire and standardized physical examination were employed to gather biopsychosocial data. Follow-up data were collected every month for the incidence of LBP. A regression model was built to analyze factors predicting the onset of LBP. Path analysis was performed to examine direct and indirect associations between identified risk factors and LBP.Results
The onset of LBP was predicted by history of LBP, frequency of rest breaks, and psychological demand, measured by the Job Content Questionnaire. All 3 factors directly related to LBP; history of LBP was the strongest effector on the onset of LBP. History of LBP and frequency of rest breaks had indirect effects on LBP that were mediated through psychological demand, and frequency of rest breaks was the most influential effector on psychological demand.Conclusions
Three risk factors were identified to predict onset LBP, including history of LBP, frequency of rest breaks, and psychological demand. Each factor had direct effects on the development of LBP. Also, history of LBP and frequency of rest breaks had indirect effects on LBP that were mediated through psychological demand. 相似文献3.

Objective
The purpose of this study was to evaluate the effectiveness of various types of exercise for prevention and cure of nonspecific neck pain in office workers.Methods
Publications between 1980 and April 2010 were systematically searched in various databases (PubMed, CINAHL Plus with full text, The Cochrane Library, Science Direct, PEDro, ProQuest, PsycNet, and Scopus). The following key words were used: neck pain, cervical pain, exercise, strengthening, stretching, endurance, office workers, visual display unit, visual display terminal, and computer users. A hand search of relevant journals was also carried out. Relevant randomized controlled trials were retrieved and assessed for methodological quality by 2 independent reviewers. The strength of the evidence was based on methodological quality and consistency of the results.Results
Nine randomized controlled trials were included in this review, of which 6 were rated as high-quality studies. No exercise type was identified as being effective in the prevention of nonspecific neck pain in office workers. Strong evidence was found for the effectiveness of muscle strengthening and endurance exercises in treating neck pain. Moderate evidence supported the use of muscle endurance exercise in reducing disability attributed to neck pain.Conclusion
Literature investigating the efficacy of exercise in office workers with nonspecific neck pain was heterogeneous. Within the limitations, for treatment of neck pain, either muscle strengthening or endurance exercise is recommended, whereas for reduction of pain-related disability, muscle endurance exercise is suggested. Further research is needed before any firm conclusions regarding the most effective exercise programs for office workers can be reached. 相似文献
