Methods of posture analysis for computer workers

Abstract

Musculoskeletal disorders (MSDs) have been identified as a predisposing factor for lesser productivity and are considered to be a major occupational health problem contributing significantly to absenteeism, disability and loss of productivity. Computer users may develop musculoskeletal disorders due to the forces applied, muscle use, posture and wrist velocity and acceleration exposures during computer use. Work-related musculoskeletal disorders (WMSDs) in computer users cause substantial worker discomfort, disability and loss of productivity. The aim of this study is to review systematically the relevant literature on applicable posture analysis methods to computer workers. A bibliographic survey based on PRISMA statement methodology was performed. A review on different approaches for computer workers posture was accomplished and noted that the simultaneous utilization of the different methods allows achieving better posture analysis, compared to situations when each one of them was used individually.

“…Sedentary behavior (SB) has been identified as a primary reason for WMSDs (Falck et al, 2018). Thus, measuring physical activity and SB in the workplace has been considered in several studies (Maheronnaghsh, Santos, and Vaz, 2018;Neuhaus et al, 2014;Quante et al, 2015).…”

“…Various methods were utilized to measure SB/PA in previous studies; questionnaire-based methods have been most frequently used until recently. Although they are lowcost method, easy to use with low participant burden but to address some of the limitations in self-report, researchers tend to use technological innovations in objective monitoring of SB, such as accelerometers and posture sensors (Healy et al 2011;Maheronnaghsh, Santos, and Vaz 2018).…”

“…Apesar de ser região corporal de destaque no acometimento de lesões osteomusculares, a coluna não é a única região corporal sintomática relacionada a condições laborais, Ombros, Cotovelos e Antebraço são apontados também com grandes índices de sintomas relacionados aos afastamentos do trabalho , o que justifica uma avaliação global de sobrecargas em todas as regiões do corpo. Maheronaghsh et al (2018) em seu estudo sobre usuários de computadores e desenvolvimento de doenças osteomusculares, levantam a necessidade de uma detalhada investigação biomecânica divido à sobrecarga relacionada às DORTs. Ainda nesse contexto, segundo Sousa et al (2016), é fato indiscutível que as tecnologias digitais estão cada dia mais presentes na vida da população, a ponto de hoje pensar na saúde do trabalhador ou da população em geral sem considerar que vivemos na era digital e que já temos gerações natodigitais, é ter uma visão limitada da realidade.…”
