ارتباط بین وضعیت نشستن در کلاس درس و دردهای اسکلتی – عضلانی دانش آموزان پسر مقطع ابتدایی

Background: Undesirable sit-up and deviation from desirable status is one of the factors affecting the health of students in the classroom. The purpose of this study was to evaluate the relationship between posture and musculoskeletal pain in boys 9 to 13 years old. Methods: In this correlation study, the population consisted of all boy students in the primary city of Birjand. 60 students were selected as a sample group based on random-cluster method. Two video cameras were recorded 30 minutes of sitting position for every student. The anthropometric characteristics of subjects including height, weight, etc., were measured with a standard tool. The back and neck pain were collected using a modified Nordic questionnaire. Moreover, the kinovea software was used to analyze the flexion and rotation angle during sitting. The statistical calculations were applied by Kolmogorov-Smirnov normality test. The ETA correlation coefficient also was used to identify the relationship between variables. All statistical calculations performed using SPSS version 21. Results: The result indicated significant relationship between bending and rotation angles with both neck and back pain (P≤0.05). Therefore it would be noticed that improper sitting can be accounted as a cause of muscle-skeletal pain in boy students based on bad postures during sitting. Conclusion: According to the results, the posture of students while sitting in class is inadequate and harmful. Thus performing some intervention and education for students is recommended.
