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 .

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 .
Dose-response relationship of specific training to reduce chronic neck pain and disability.
PURPOSE To examine the dose-response relationship of specific strength- and endurance-training regimes for the cervical muscles , which have been shown to be effective among women with chronic neck pain and disability . METHODS A total of 180 female office workers , aged 25 to 53 yr , with chronic neck pain and disability were r and omized into a strength-training , an endurance-training , and a control group . The training groups participated in a 12-d rehabilitation period , in which instructions for the exercises were given by an experienced physical therapist . Both training groups continued with exercises at home for 12 months . Physical activity was measured with a training diary and a 1-month all-time recall question naire . All activities were registered and converted into metabolic equivalents ( METs ) . RESULTS Specific neck , shoulder , and upper-extremity training for more than 8.75 MET.h.wk was an effective training dose for decreasing neck pain . One MET-hour of training per week accounted for an 0.8-mm decrease of neck pain on a visual analog scale ( VAS ) and a 0.5-mm decrease on a disability index . Both strength and endurance training decreased perceived neck pain and disability . Declines in neck pain and disability correlated positively with the amount of specific training . CONCLUSION This study revealed that the described specific exercise protocol s were associated with decreases in chronic neck pain and disability . The effective dose of training was feasible and safe to perform among female office workers
