None of the ergonomic interventions was more beneficial for any outcome measures when compared with another treatment or with no treatment or with placebo .
Behavioural interventions had inconsistent effects on pain and disability , with some subgroups showing benefit and others showing no significant improvement when compared with no treatment , minor intervention controls or other behavioural interventions .In the eight studies that evaluated various other interventions , there was no evidence of a clear beneficial effect of any of the interventions provided .
We found very low- quality evidence indicating that pain , recovery , disability and sick leave are similar after exercises when compared with no treatment , with minor intervention controls or with exercises provided as additional treatment to people with work-related complaints of the arm , neck or shoulder .
Low- quality evidence also showed that ergonomic interventions did not decrease pain at short-term follow-up but did decrease pain at long-term follow-up .
There was no evidence of an effect on other outcomes .
For behavioural and other interventions , there was no evidence of a consistent effect on any of the outcomes .
BACKGROUND Work-related upper limb disorder ( WRULD ) , repetitive strain injury ( RSI ) , occupational overuse syndrome ( OOS ) and work-related complaints of the arm , neck or shoulder ( CANS ) are the most frequently used umbrella terms for disorders that develop as a result of repetitive movements , awkward postures and impact of external forces such as those associated with operating vibrating tools .
Work-related CANS , which is the term we use in this review , severely hampers the working population .
OBJECTIVES To assess the effects of conservative interventions for work-related complaints of the arm , neck or shoulder ( CANS ) in adults on pain , function and work-related outcomes .
The Delphi list: a criteria list for quality assessment of randomized clinical trials for conducting systematic reviews developed by Delphi consensus.
Most systematic review s rely substantially on the assessment of the method ological quality of the individual trials . The aim of this study was to obtain consensus among experts about a set of generic core items for quality assessment of r and omized clinical trials ( RCTs ) . The invited participants were experts in the field of quality assessment of RCTs . The initial item pool contained all items from existing criteria lists . Subsequently , we reduced the number of items by using the Delphi consensus technique . Each Delphi round comprised a question naire , an analysis , and a feedback report . The feedback report included staff team decisions made on the basis of the analysis and their justification . A total of 33 international experts agreed to participate , of whom 21 completed all question naires . The initial item pool of 206 items was reduced to 9 items in three Delphi rounds . The final criteria list ( the Delphi list ) was satisfactory to all participants . It is a starting point on the way to a minimum reference st and ard for RCTs on many different research topics . This list is not intended to replace , but rather to be used alongside , existing criteria lists
