Abstract

The objective of the study is to determine the prevalence of musculoskeletal disorders due to forced postures in teachers who perform telework in the city of Quito, Ecuador. Materials and methods: a cross-sectional descriptive study was carried out in teachers who are working in a private educational center, to determine the forced postures, the job position was analyzed with the REBA method and the Nordic Kuorinka questionnaire was applied to determine muscle symptoms - skeletal. Results: In the job analysis, 5 positions were found that exceed the comfortable angles with a medium risk level and 2 action level. These positions may be related to the high prevalences of musculoskeletal discomfort found in teachers. 100% of professionals presented discomfort at the dorsal-lumbar region, 80% presented discomfort at the neck level and 73% presented discomfort at the level of the hands and wrists. The least affected segments were shoulders and elbows. 80% of the professionals said they were in front of a computer for 8-10 hours a day, 13.3% said that they spent more than 10 hours a day sitting in front of the computer and 6.6% spent 4-6 hours in front of the computer . Conclution. Most of the teachers who perform telework have osteo-muscular symptoms, especially at the spine level, this study serves as the basis for future research to establish the cause-effect relationship between the positions found and the symptoms referred by the teachers
