Zemp R Fliesser M Wippert PM Taylor WR Lorenzetti S 2016 Nowadays, working in an office environment is ubiquitous. At the same time, progressively more people suffer from occupational musculoskeletal disorders. Therefore, the aim of this pilot study was to analyse the influence of back pain on sitting behaviour in the office environment. A textile pressure mat (64-sensor-matrix) placed on the seat pan was used to identify the adopted sitting positions of 20 office workers by means of random forest classification. Additionally, two standardised questionnaires (Korff, BPI) were used to assess short and long-term back pain in order to divide the subjects into two groups (with and without back pain). Independent t-test indicated that subjects who registered back pain within the last 24 h showed a clear trend towards a more static sitting behaviour. Therefore, the developed sensor system has successfully been introduced to characterise and compare sitting behaviour of subjects with and without back pain. https://sonar.ch/global/documents/267361 eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.apergo.2016.03.007 info:eu-repo/semantics/altIdentifier/pmid/27184315 Applied ergonomics. - 2016 Musculoskeletal disorders Office chair Pressure distribution Adult Algorithms Back Pain Female Humans Male Middle Aged Occupational Diseases Occupational Health Pain Measurement Pilot Projects Posture Surveys and Questionnaires Occupational sitting behaviour and its relationship with back pain - A pilot study. http://purl.org/coar/resource_type/c_6501
