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 .
Effect of Four Computer Keyboards in Computer Users with Upper Extremity Musculoskeletal Disorders
Eighty computer users with musculoskeletal disorders participated in a six-month , r and omized , placebo-controlled trial evaluating the effects of four computer keyboards on clinical findings , pain severity , functional h and status , and comfort . The alternative geometry keyboards tested were : the Apple Adjustable Keyboard ™ [ kb1 ] , Comfort Keyboard System ™ [ kb2 ] , Microsoft Natural Keyboard ™ [ kb3 ] and placebo . Compared to placebo , kb3 and to a lesser extent kb1 groups demonstrated an improving trend in pain severity and h and function following six months of keyboard use . However , there was no corresponding consistent improvement in clinical findings in the alternative geometry keyboard groups compared to the placebo group . Overall , there was a significant correlation between improvement of pain severity and greater satisfaction with the keyboards . These results provide evidence that keyboard users may experience a reduction in h and pain after several months of use of some alternative geometry keyboards
