Conditions
Summary
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.

Interventions
This intervention is based on the Social Cognitive Theory (SCT) to improve knowledge, attitudes, and practices (KAP) regarding work-related musculoskeletal disorders (MSDs), while enhancing ergonomics, mental health, and physical activity among dental healthcare workers in Dubai government hospitals. This program will include educational booklets, lectures, workshops, demonstrations, practical exercises, and stretching sessions over multiple weeks. The course will include six weekly teaching units (lectures, discussions, and hands-on practice, 45-60 minutes each): Topic 1: Understanding MSD causes and risk factors in dental practice. Topic 2: Ergonomic principles and proper postures. Topic 3: Optimizing equipment and operator-patient positioning. Topic 4: Recognizing early MSD symptoms and prevention strategies. Topic 5: Incorporating rest breaks and time management. Topic 6: Promoting physical activity and stretching routines.
