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 .

Musculoskeletal work disability for clinicians: time course and effectiveness of a specialized intervention program by diagnosis.
OBJECTIVE To evaluate how an intervention program modifies the clinical course of work disability in musculoskeletal diagnoses . METHODS All patients with temporary work disability related to musculoskeletal disorders ( MSDs ) in 3 health districts of Madrid , Spain were r and omized into st and ard care ( control group ) or the intervention group . Intervention consisted of a specific program , run by rheumatologists , following detailed proceedings . Inclusion and followup lasted 12 months each . According to the cause , every temporary work disability episode was classified into 11 syndrome categories . For each we calculated efficacy , as the difference between groups in the number of days on sick leave per temporary work disability episode ; relative efficacy , or the percentage of days saved in the intervention group ; and time of maximum program effect . Analyses were performed on an intent-to-treat basis . Survival techniques were run and results were expressed as the hazard ratio ( HR ) in the intervention versus control group . RESULTS A total of 13,077 patients were included , generating 16,297 temporary work disability episodes .  The most frequent cause was back pain . Temporary work disability episodes were significantly shorter in the intervention group than in the controls in all syndrome categories except knee pain ( excluding osteoarthritis ) . Program relative efficacy varied from 28 - 72 % . The program was highly efficacious in carpal tunnel syndrome ( HR 2.09 , 95 % confidence interval [ 95 % CI ] 1.17 - 3.75 ) , peripheral osteoarthritis ( HR 1.58 , 95 % CI 1.14 - 2.19 ) , and inflammatory diseases ( HR 1.52 , 95 % CI 1.09 - 2.12 ) . The maximum effect of the program always took place within the first 2 months . CONCLUSION The implementation of this type of specialist-run , protocol -based early intervention program would be very beneficial in the treatment of patients with work disability related to MSDs , except for those with knee pain ( excluding osteoarthritis )
