Abstract
Objectives: Inappropriate sitting posture on bench can contribute to pain and musculoskeletal disorders in students. Hearing and vision disabilities may be the cause of inappropriate sitting postures among students. Therefore, the aim of the present study was to compare the risk of musculoskeletal disorders in normal and students with hearing abnormalities in Ilam city.
Methods: Twenty students with hearing abnormalities (case) and 40 students with normal hearing (control) from primary schools in Ilam city of both genders were randomly included in the study. The worst recorded sitting posture of students on the bench was evaluated by the RULA method. Digimizer software was used to survey the body angles of the students while sitting on the bench. The used for analyzing the obtained data in 95% confidence interval.
Results: The results of posture evaluation showed that there was a significant difference in rula scores between case and control groups (P = 0.001). Deviation from the natural angles of the body in the case groups was more than the control group (P < 0.001), which has a direct and significant relationship with the increased risk of musculoskeletal disorders.
Conclusion: Musculoskeletal disorders possibility incidence were more common in students with hearing abnormalities compared to typical students which was due to an increase in deviation from the natural angles of the body and inappropriate postures. Given the limitation of the sample size, the present study recommends further research with the same goal and encourages interventional studies to correct the posture of hard of hearing students.
