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 .
Rehabilitation of neck-shoulder pain in women industrial workers: a randomized trial comparing isometric shoulder endurance training with isometric shoulder strength training.
OBJECTIVES To study whether isometric shoulder endurance was more advantageous than isometric shoulder strength training in reducing pain and perceived exertion and to increase shoulder function through improved muscle endurance and strength . DESIGN R and omized trial . SETTING Three occupational health care centers . PARTICIPANTS Women industrial workers with nonspecific neck-shoulder pain . The International Classification of Diseases , 10th Revision ( ICD-10 ) diagnosis was " cervicobrachial syndrome " ( M53.1 ) . Thirty-eight patients completed the isometric shoulder endurance training  and 31 patients completed the isometric shoulder strength training . INTERVENTION Twelve weeks of training . MAIN OUTCOME MEASURES Self-reported pain and rating of perceived exertion ( RPE ) , arm motion performance test , shoulder muscle strength , shoulder muscle endurance , and shoulder functional tests , as well as follow-up after supervised training had ended . RESULTS The isometric shoulder strength training result ed in an almost one-scale step decrease in RPE at work and a 5 % to 15 % improvement of arm motion performance compared with the endurance training . The isometric shoulder strength training more effectively improved left side shoulder abduction strength ( p < .026 ) , but no major differences were found for the other strength measurements . The isometric shoulder endurance training was not more successful than the strength training in the endurance test ( p .51 to .81 ) . CONCLUSIONS Physical training programs for neck-shoulder pain may include isometric shoulder muscular strength exercise in addition to isometric shoulder endurance training , rather than endurance training only
