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 .

Effect of keyboard keyswitch design on hand pain.
This r and omized clinical trial evaluated the effects of keyboard keyswitch design on computer users with h and paresthesias . Twenty computer users were matched and r and omly assigned to keyboard A ( n = 10 ) or B ( n = 10 ) . The keyboards were of conventional layout and differed in keyswitch design . Various outcome measures were assessed during the 12 weeks of use . Subjects assigned keyboard A experienced a decrease in h and pain between weeks 6 and 12 when compared with keyboard B subjects ( P = 0.05 ) and demonstrated an improvement in the Phalen test time ( right h and , P = 0.006 ; left h and , P = 0.06 ) . Keyboard assignment had no significant effect on change in h and function or median nerve latency . We conclude that use of keyboard A for 12 weeks led to a reduction in h and pain and an improved physical examination finding when compared with keyboard B. There was no corresponding improvement in h and function or median nerve latency
