Determination of Risk Factors for Musculoskeletal Disorders and Corrective Priorities to Perform the Work in Dental Careers by Posture Analysis Using REBA in Shahrekord

Abstract

Background and aims: Nowadays, work-related musculoskeletal disorders are the most common<br />occupational diseases. The prevention of these disorders requires a posture analysis during work<br />and the improvement of working conditions. The purpose of this study was to determine risk factors<br />for musculoskeletal disorders and corrective priorities to perform the work by conducting postures<br />analysis using Rapid Entire Body Assessment (REBA).<br />Methods: In this descriptive-analytical study, the posture of dentists during working was analyzed<br />using the REBA software. The incidence rate of musculoskeletal disorders was investigated by the<br />Nordic Musculoskeletal Questionnaire (NMQ). A P value less than 0.05 was considered statistically<br />significant.<br />Results: In this applied study, the incidence rates of the pain in neck, waist, shoulders, and wrists<br />were reported to be 68%, 55%, 41% and 28%, respectively. The above-mentioned values were higher<br />in women than in men. The pain in thigh and leg was related to work and the pain in ankle and<br />sole was related to body mass index (BMI). The relationship between musculoskeletal disorders and<br />occupational postures of dentists was statistically significant (P < 0.05).<br />Conclusion: Training the principles of ergonomics and anthropometrics, the correct methods and<br />principles of performing work, and the ways of using the instruments are necessary for the studied<br />population. Occupational postures require ergonomic intervention and correction.
