The Effectiveness of Ergonomics Intervention Program to Reduce the Risk Factors of Musculoskeletal

This study evaluates an ergonomics intervention to reduce work-related musculoskeletal disorders (MSDs) among dental healthcare workers in Dubai government hospitals, where up to 90% prevalence affects the lower back, neck, shoulders, and upper extremities due to repetitive tasks and postures. Using a cluster randomized controlled trial (RCT) across three hospitals (55 participants per intervention/control group), it assesses MSD prevalence/severity, mental health, physical activity, and KAP scores at baseline, post-intervention, and three-month follow-up. Analyses include logistic regression, ANOVA, and GEE. Expected outcomes: identify predictors and demonstrate intervention efficacy via education, environmental, and behavioral changes, informing UAE occupational health policies.
