Conclusion The findings of this review indicate a consistent trend that supports the role of a chair intervention to reduce musculoskeletal symptoms among workers who are required to sit for prolonged periods .
The review also highlights gaps : for example in showing whether the effectiveness of a chair intervention has long-term impact , particularly with respect to musculoskeletal symptoms , as well as the recurrence of symptoms and the consequent cost of care
Background Prolonged sitting has been associated with musculoskeletal dysfunction .
For desk workers , workstation modifications frequently address the work surface and chair .
Chairs which can prevent abnormal strain of the neuromuscular system may aid in preventing musculo-skeletal pain and discomfort .
Anecdotally , adjustability of the seat height and the seat pan depth to match the anthropometrics of the user is the most commonly recommended intervention .
Within the constraints of the current economic climate , employers dem and evidence for the benefits attributed to an investment in altering workstations , however this evidence -base is currently unclear both in terms of the strength of the evidence and the nature of the chair features .
The purpose of this study was to evaluate the evidence for the effectiveness of chair interventions in reducing workplace musculoskeletal symptoms .
Musculoskeletal, visual and psychosocial stress in VDU operators before and after multidisciplinary ergonomic interventions. A 6 years prospective study--Part II.
A prospect i ve epidemiological field study covering a 2 years period has earlier been published . The study has a parallel group design with two intervention groups ( T and S ) and one  control group ( C ) of Visual Display Unit ( VDU ) operators . The present paper covers the period from 2 to 6 years of the study . After 3.5 years , the C group got the same intervention in terms of new lighting system , new workplaces and at last an optometric examination and corrections if needed . The C group reported a significant reduction in visual discomfort after interventions while the two groups ( T and S ) continued to report significant reduction of visual discomfort after 6 years . By supporting the forearm on the table top , the C group reported significant reduction of shoulder and neck pain while the T group reported significant reduction in shoulder and back pain after 6 years . Organizational and psychosocial factors at work and outside work did not show any significant changes during the study period
