The effectiveness of a dynamic seat cushion in preventing neck and low-back pain among high-risk office workers: a 6-month cluster-randomized controlled trial.
Objective: This study evaluated the effectiveness of the promotion of postural shift intervention using a dynamic seat cushion on the 6-month incidence of neck and low-back pain among high-risk office workers.
Methods: In a cluster-randomized controlled trial (RCT), 133 office workers were randomly assigned, at cluster level, to intervention (N=67) and control (N=66) groups. The intervention group received a dynamic seat cushion to encourage postural shifts during sitting, while the control group received a placebo seat pad. Primary outcomes were 6-month incidence of neck and low-back pain. Secondary outcomes included sitting discomfort, pain intensity, disability, and trunk muscle performance. Analyses utilized Cox proportional hazard models.
Results: During the 6-month period, 15% of participants in the intervention group developed neck pain and 10% developed low-back pain. For the control group, this was 65% and 59%, respectively. Hazard rate (HR) ratios, after adjusting for biopsychosocial factors, indicated a protective effect of the intervention for neck pain [HRadj 0.19, 95% confidence interval (CI) 0.09-0.39, P<0.001] and low-back pain (HRadj 0.16, 95% CI 0.07-0.35, P<0.001). The intervention group demonstrated a significant reduction in sitting discomfort and improvement in trunk muscle performance compared to the control group (P<0.05). However, the intervention did not reduce pain and disability in individuals experiencing pain compared to the control group.
Conclusions: The dynamic seat cushion effectively reduced the incidence of neck and low-back pain by promoting postural shifts. These findings suggest that the key factor in reducing the risk of developing neck and low-back pain is the facilitation of postural shifts during sitting, which can potentially be achieved with other dynamic interventions designed to reduce prolonged and static sitting among office workers.
期刊介绍：
The aim of the Journal is to promote research in the fields of occupational and environmental health and safety and to increase knowledge through the publication of original research articles, systematic reviews, and other information of high interest. Areas of interest include occupational and environmental epidemiology, occupational and environmental medicine, psychosocial factors at work, physical work load, physical activity work-related mental and musculoskeletal problems, aging, work ability and return to work, working hours and health, occupational hygiene and toxicology, work safety and injury epidemiology as well as occupational health services. In addition to observational studies, quasi-experimental and intervention studies are welcome as well as methodological papers, occupational cohort profiles, and studies associated with economic evaluation. The Journal also publishes short communications, case reports, commentaries, discussion papers, clinical questions, consensus reports, meeting reports, other reports, book reviews, news, and announcements (jobs, courses, events etc).
