La présente étude visait à définir des modèles spécifiques de TMS multisites chez les employés de bureau et à examiner comment les modèles dérivés sont liés à la conception d’un fauteuil ergonomique.
Background: The present study aimed to define specific patterns of multisite MSDs of office employees and to examine how derived patterns are related to the ergonomic chair design.Methods: in this cross-sectional study of 254 office employees, major patterns of MSDs were extracted using latent class analysis and investigated its association with the ergonomic chair design.Results: Four major patterns of MSDs were extracted using latent class analysis. Class 1 (12.1%) was characterized by individuals with high probabilities of MSDs in the neck, shoulders, back, and wrists. Class 2 (36.6%) was marked by individuals with near-zero probabilities of MSDs across all sites. Class 3 (14.1%) included high probabilities of complaints in the back, hips, and knees. Class 4 (38.2%) accounted for those with high probabilities of MSDs across all sites. Considering class 2 as the reference, there was an inverse significant association between seat comfort and membership to class 3 (OR=0.94, 95%CI [0.89-0.99]) and class 4 (OR=0.94, 95%CI [0.91-0.98]) and a significant inverse relationship between body support and membership to class 4 (OR=0.95, 95%CI [0.92-0.99]).Conclusion: MSDs can be summarized with latent class-derived patterns among the office workers. Ergonomic chair design was significantly associated with the type of MSDs patterns.
