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 .
A Randomized Controlled Trial of Chair Interventions on Back and Hip Pain Among Sewing Machine Operators: The Los Angeles Garment Study
Objective : Determine whether an adjustable chair with a curved or a flat seat pan improved monthly  back and hip pain scores in sewing machine operators . Methods : This 4-month intervention study r and omized 293 sewing machine operators with back and hip pain . The participants in the control group received a placebo intervention , and participants in the intervention groups received the placebo intervention and one of the two intervention chairs . Results : Compared with the control group , mean pain improvement for the flat chair intervention was 0.43 points ( 95 % CI = 0.34 , 0.51 ) per month , and mean pain improvement for the curved chair intervention was 0.25 points ( 95 % CI = 0.16 , 0.34 ) per month . Conclusions : A height-adjustable task chair with a swivel function can reduce back and hip pain in sewing machine operators . The findings may be relevant to workers who perform visual- and h and -intensive manufacturing jobs
