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 .

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 effect of pain reduction on perceived tension and EMG-recorded trapezius muscle activity in workers with shoulder and neck pain.
The study was initiated to evaluate the effect of pain-reducing therapies on factors previously associated with work-related shoulder and neck pain , namely increased muscle activity in the upper trapezius and perceived general tension . Thirty-three women in three groups were assessed before and after an intervention period and by question naire 6 months later . The purpose of this study was primarily to investigate associations between upper trapezius muscle activity , perceived general tension and pain , and secondly , to compare effects of individually based physiotherapy and group exercise for workers with shoulder and neck myalgia . All three groups reported a significant alleviation of pain and perceived general tension , while the electromyographically ( EMG ) recorded upper trapezius muscle activity level remained unchanged or increased . Improvements were similar in all three treatment groups , but individual-based therapies were rated more beneficial on subjective measures . Significant correlation was found between pain and perceived general tension ( r = 0.66 , p < 0.01 ) , while there was no correlation between pain or perceived general tension and recorded muscle activity
