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.<\/jats:p>\n                    <jats:p>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 [HR<jats:sub>adj<\/jats:sub> 0.19, 95% confidence interval (CI) 0.09\u20130.39, P&lt;0.001] and low-back pain (HR<jats:sub>adj<\/jats:sub> 0.16, 95% CI 0.07\u20130.35, P&lt;0.001). The intervention group demonstrated a significant reduction in sitting discomfort and improvement in trunk muscle performance compared to the control group (P&lt;0.05). However, the intervention did not reduce pain and disability in individuals experiencing pain compared to the control group.<\/jats:p>\n                    <jats:p>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.<\/jats:p>","DOI":"10.5271\/sjweh.4184","type":"journal-article","created":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T08:31:03Z","timestamp":1724315463000},"page":"555-566","source":"Crossref","is-referenced-by-count":4,"title":["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"],"prefix":"10.5271","volume":"50","author":[{"given":"Sirinant","family":"Channak","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erwin M","family":"Spekl\u00e9","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allard J","family":"van der Beek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prawit","family":"Janwantanakul","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3229","published-online":{"date-parts":[[2024,8,22]]},"container-title":["Scandinavian Journal of Work, Environment &amp; Health"],"original-title":[],"language":"en","deposited":{"date-parts":[[2024,9,30]],"date-time":"2024-09-30T09:20:49Z","timestamp":1727688049000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.sjweh.fi\/article\/4184"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,8,22]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2024,10,1]]}},"alternative-id":["4184"],"URL":"https:\/\/doi.org\/10.5271\/sjweh.4184","relation":{},"ISSN":["0355-3140","1795-990X"],"issn-type":[{"value":"0355-3140","type":"print"},{"value":"1795-990X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,8,22]]}}}
