Cette étude vise à comparer les changements dans les angles du cou, les activités musculaires, le risque ergonomique et l’inconfort corporel causés par l’utilisation de deux tailles d’écran d’ordinateur différentes.
This study aims to compare the changes in neck angles, muscle activities, ergonomic risk, and body discomfort caused by the use of two different computer screen sizes. The 36 female users participated and used displays with 46.99 and 58.42-centimeter screen sizes who were assessed for craniocervical angle (CCA), craniovertebral angle (CVA), upper trapezius (UT), and sternocleidomastoid (SCM) muscle activity, ergonomic risk, and body discomfort for a duration of 1 hour. The results showed there were no significant differences when comparing between both computer screen sizes usage (p > 0.05). However, there were significant differences in the CCA, UT muscle activity, and body discomfort when comparing between before and after usage for both computer screen sizes (p < 0.05). The results indicate that computer users can select different screen sizes for working but should be concerned with neck angle, muscle activity, and body discomfort when using for long periods of time.
