title: A field intervention examining the impact of an office ergonomics training and a highly adjustable chair on visual symptoms in a public sector organization.
abstract: OBJECTIVE
  Examine the effect of a multi-component office ergonomics intervention on visual symptom reductions.
  
  
  METHODS
  Office workers were assigned to either a group receiving a highly adjustable chair with office ergonomics training (CWT), a training-only group (TO) or a control group (C). A work environment and health questionnaire was administered 2 and 1 month(s) pre-intervention and 3, 6, and 12 months post-intervention. Multi-level statistical models tested hypotheses.
  
  
  RESULTS
  The CWT intervention lowered daily visual symptoms (p < 0.01) post-intervention. The TO group did not significantly differ from the control group. The CWT group differed significantly from the TO group (p = 0.01) post-intervention.
  
  
  CONCLUSIONS
  Workers who received a highly adjustable chair and office ergonomics training had reduced visual symptoms and the effect was maintained through twelve months post-intervention. The lack of a training-only group effect supports implementing training in conjunction with the highly adjustable chair to reduce visual symptoms.
