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 .
Effects of Training on Female Trapezius Myalgia: An Intervention Study With a 3-Year Follow-up Period
Study Design . A prospect i ve r and omized clinical trial was conducted . Objective . To evaluate the long-term effects of three training interventions on women with work-related trapezius myalgia . Summary of Background Data . Studies with long-term follow-up evaluation of interventions for neck pain are scarce and usually cover fewer than 12 months . Methods . For this study , 126 women with work-related trapezius myalgia were r and omized into strength , muscular endurance , or coordination training or into a nontraining reference group . Intervention training occurred three times a week for 10 weeks . Assessment of pain intensity , pressure pain thresholds , symptom frequency , perceived health , and work and exercise habits was performed before and immediately after interventions , then at clinical examinations 8 months and 17 months after the interventions . Participation rates at these follow-up assessment s were 84 % and 81 % . At 3 years after the interventions , a question naire was answered by 94 % of the participants , 17 of whom were dropouts that never participated in any of the four intervention groups . Results . All the training programs showed similar pain reducing effects immediately after the interventions . Pain reductions were maintained at follow-up evaluations , but at the 8-month follow-up assessment , there were no differences between the training groups and the reference group on any variable . At 3 years after the interventions , the intervention groups did not differ from the dropout group . Almost half ( 49 % ) of the women had persistent symptoms at the 3-year follow-up assessment . Conclusions . The long-term effect of all the training programs was low . Pain in neck and shoulder muscles was persistent in a large proportion of the women over the 3 years
