Musculoskeletal Disorders (MSD) have a major impact on the health of individuals and their occupational performance. In the field of teaching, the MSD become apparent a long time after the beginning of the triggers actions, especially the position.
Objective: Determine the prevalence of Musculoskeletal Symptoms (MSS) and to characterize the postural risk factors in teachers.
Methodology: Descriptive study in 38 teachers of a primary and high school educative institution of Cali, Colombia. The MSS were detected by Nordic questionnaire (n=38) and postural risk was assessed by Rapid Entire Body Assessment tool (REBA, n=15). Additionally, occupational variables as labor time, activity time (hours/day) and teaching activities were collected.
Results: The most prevalent MSS are located in the neck (19%) and lower back (15%). Since the main teaching activity is the lecture (94.7%), it was found that the most prevalent posture is bipedal with arms over shoulders (80%), generating a postural risk level 2, which implies weak inconvenience.
Conclusion: The teaching activity involves risks for the development of MSD, which may be originated in postural factors. Associative studies are needed to assess this hypothesis.
