Résumé
Musculoskeletal symptoms among school students are common. Aim of this study was the study of prevalence of discomfort and musculoskeletal symptoms in students of Tehran. 340 primary and secondary school students participated in this study. Subjects from five different districts of Tehran - a school from each region- were selected. Nordic questionnaire was used for review of musculoskeletal symptoms and discomfort. Also body map was used to show location of musculoskeletal symptoms and discomfort. Shoulders and neck musculoskeletal discomfort and pain respectively were reported about 18.46 and 13.42%. Musculoskeletal pain in back was 8.5%. Also complaints from musculoskeletal discomfort and pain in upper and lower extremities respectively were 5.5 and 2.9 percent. Musculoskeletal symptoms are clearly seen in school students. These symptoms in upper trunk especially in shoulders and also in the neck region are more evident. These symptoms and discomforts often are not caused by disease and illness. So, there is a need for further research in this area to investigate the causes of these symptoms
