Summary

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.

Detailed description

This clinical investigation is a prospective, randomized, controlled, counter-balanced, two-arm field study investigating the effect of dynamic sitting on musculoskeletal pain in office workers classified as pain developers. The study consists of a pre-screening visit and 4 assessment days / visits. During this pre-screening visit and after proving the study eligibility (inclusion / exclusion criteria), half of the study participants will randomly be allocated to one of the two study arms. Depending on the arm allocation, participants will receive a dynamic (= intervention) or static (= control) office chair for 6 weeks. After a wash-out of at least 4 weeks the 6-week intervention resp. control will be switched. The randomization will be realized with opaque envelopes. Overall participants will execute the identical assessments within the control and the intervention chair group. The wash-out phase between the control and the intervention periods will ensue identical baseline conditions for both chairs. The overall duration of study participation amounts to 16 weeks.

Conditions

• Lower Back Pain

Interventions

Type	Name	Description
DEVICE	Dynamic office chair	The dynamic office chair has a typical office chair design (e.g. seat pan and a lumbar support). The seat pan is mounted on a flexible mechanic construction that allows hip movements in the frontal plane while sitting.
