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 .
No difference between postural exercises and strength and fitness exercises for early, non-specific, work-related upper limb disorders in visual display unit workers: a randomised trial.
QUESTION Are postural exercises delivered by Mensendieck/Cesar therapists more effective in decreasing pain , reducing disability and improving health-related quality of life in visual display unit workers with early non-specific work-related upper limb disorders than strength and fitness exercises delivered by physiotherapists ? DESIGN R and omised trial with concealed allocation and intention-to-treat analysis . PARTICIPANTS Eighty-eight ( 6 drop-outs ) visual display unit workers with early non-specific work-related upper limb disorders . INTERVENTION One group received 10 weeks of postural exercises while the other group received 10 weeks of strength and fitness exercises . OUTCOME MEASURES Pain was measured with a 10-cm visual analogue scale , disability was measured with the Disabilities of Arm , Shoulder and H and question naire , and health-related quality of life was measured with the Short Form-36 . Number of participants experiencing upper limb complaints was also collected . Outcome measures were collected at baseline and again at 3 , 6 , and 12 months . RESULTS There was no significant difference in decrease in pain between the groups at 3 months ( 0.6 cm , 95 % CI 0.0 to 1.2 ) , 6 months ( 0.2 , 95 % CI -0.3 to 0.7 ) , or at 12 months ( 0.1 , 95 % CI -0.6 to 0.8 ) . Differences between the groups in upper limb complaints , disability , and health related quality of life were also small and not significant at any measurement occasion . CONCLUSION Postural exercises did not result in a better outcome than strength and fitness exercises . However , 55 % of visual display unit workers with early non-specific work-related upper limb disorders reported being free of complaints one year after both interventions were commenced . TRIAL REGISTRATION IS RCT N15872455
