Schedules of standing and sitting directed by musculoskeletal discomfort in workers transitioning to sit-stand workstations: a cross-sectional study.

Refined guidelines are needed regarding effective use of sit-stand workstations. This study proposed a novel method of investigating potentially optimal schedules, in which postural change was based on reaching a threshold of musculoskeletal discomfort. The findings suggest that an optimal schedule may vary with time and be individual-specific.
