Effect of Dynamic Sitting on Pain Development

Worksite based prolonged static sitting postures can cause musculoskeletal pain. While the development of pain increases due to the constant growth of digitalization at work, numerous interventions to reduce prolonged sitting periods have been created. The effects of such interventions have not yet been properly examined. Thus, the "DynSit-Pain" project was initiated to investigate the influence of dynamic sitting on the pain development of pain developers in office environments.
