There was limited evidence that computer keyboards with altered force displacement characteristics or altered geometry were effective in reducing carpal tunnel syndrome symptoms .
There was limited , but high quality , evidence that multi-disciplinary rehabilitation for non-specific musculoskeletal arm pain was beneficial for those workers absent from work for at least four weeks .
In adults with tenosynovitis there was limited evidence that modified computer keyboards were effective in reducing symptoms .
There was a lack of high quality evidence to inform workplace management of lateral epicondylitis .

A randomised controlled trial evaluating an alternative mouse and forearm support on upper body discomfort and musculoskeletal disorders among engineers
Objectives : The aim of this intervention study was to determine the effects of an alternative mouse and /or a forearm support board on the change in upper body discomfort scores and the development of incident musculoskeletal disorders . Methods : This r and omised controlled intervention trial followed 206 engineers for one year . Participants were r and omised to receive ( 1 ) a conventional mouse only , ( 2 ) an alternative mouse only , ( 3 ) a forearm support board , or ( 4 ) an alternative mouse plus forearm support board . Outcome measures included weekly upper body discomfort scores and incident musculoskeletal disorders . Results : During the study , 42 participants were diagnosed with an incident musculoskeletal disorder . The group that received the forearm support board experienced a reduction in their right upper extremity discomfort ( beta-coefficient −0.35 , 95 % CI −0.67 to −0.03 ) in comparison to those who did not receive a forearm board . The group that received the alternative mouse had a protective , but non-significant ( p = 0.20 ) , effect on incident cases of right upper extremity musculoskeletal disorders ( HR 0.57 , 95 % CI 0.24 to 1.34 ) and a non-significant reduction in neck/shoulder discomfort ( beta-coefficient −0.23 , 95 % CI −0.056 to 0.10 ) in comparison to those who received a conventional mouse . Conclusions : In engineers who use a computer for more than 20 h per week , a forearm support board may reduce right upper extremity discomfort attributed to computer use
