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

Nowadays, work-related musculoskeletal disorders are the most commonoccupational diseases. The prevention of these disorders requires a posture analysis during workand the improvement of working conditions. The purpose of this study was to determine risk factorsfor musculoskeletal disorders and corrective priorities to perform the work by conducting posturesanalysis using Rapid Entire Body Assessment (REBA).

In this descriptive-analytical study, the posture of dentists during working was analyzedusing the REBA software. The incidence rate of musculoskeletal disorders was investigated by theNordic Musculoskeletal Questionnaire (NMQ). A P value less than 0.05 was considered statisticallysignificant.

In this applied study, the incidence rates of the pain in neck, waist, shoulders, and wristswere reported to be 68%, 55%, 41% and 28%, respectively. The above-mentioned values were higherin women than in men. The pain in thigh and leg was related to work and the pain in ankle andsole was related to body mass index (BMI). The relationship between musculoskeletal disorders andoccupational postures of dentists was statistically significant (P < 0.05).

Training the principles of ergonomics and anthropometrics, the correct methods andprinciples of performing work, and the ways of using the instruments are necessary for the studiedpopulation. Occupational postures require ergonomic intervention and correction.
