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 .

Naturopathic treatment of rotator cuff tendinitis among Canadian postal workers: a randomized controlled trial.
OBJECTIVE To explore the effectiveness of naturopathic care ( NC ) on rotator cuff tendinitis using a prospect i ve r and omized clinical trial design . METHODS Canadian postal workers with rotator cuff tendinitis for a duration of > 6 weeks were r and omized to receive NC ( n = 43 ) or st and ardized physical exercises ( PEs ; n = 42 ) over 12 weeks . Participants in the NC group received dietary counseling , acupuncture , and Phlogenzym ( 2 tablets 3 times/day ) . The PE intervention group received passive , active-assisted , and active range of motion exercises and matched placebo . The primary outcome measure was the Shoulder Pain and Disability Index ( SPADI ) , and secondary outcomes were the pain visual analog scale ( VAS ) , Short Form 36 ( SF-36 ) , Measure Yourself Medical Outcomes Profile ( MYMOP ) , and shoulder maximal range of motion . Participants and assessors were blinded to group and placebo allocation . RESULTS Seventy-seven participants ( 87 % ) completed > or=8 weeks of the trial .  Final total SPADI scores decreased by 54.5 % ( P < 0.0001 ) in the NC group and by 18 % ( P = 0.0241 ) in the PE group . Between-group differences in changes to SPADI scores showed statistically significant decreases in shoulder pain and disability in the NC group compared with the PE group ( P < 0.0001 ) . Significant differences between groups were also observed in the pain VAS , MYMOP , SF-36 , and shoulder extension , flexion , and abduction , with the NC group showing superiority in each outcome . No serious adverse reactions were observed . CONCLUSION NC and PE provided significant improvements , with greater improvement in shoulder function in the NC  group compared with the PE group . Statistically significant improvements in quality of life measures were observed in the NC group as compared with the PE group
