Thus , WIs were seldom design ed to improve return-to-work .
Overall , there was low quality evidence that showed no significant differences between WIs and no intervention for pain prevalence or severity .
If present , significant results in favour of WIs were not sustained across follow-up times .
Overall , this review found low quality evidence that neither supported nor refuted the benefits of any specific WI for pain relief and moderate quality evidence that a multiple-component intervention reduced sickness absence in the intermediate-term , which was not sustained over time .

Effects of keyboard tray geometry on upper body posture and comfort.
The effects of a downward-tilting ( DT ) keyboard tray on wrist posture , seated posture and self-assessed musculoskeletal discomfort were investigated in a field experiment . Thirty-eight professional office workers were studied . A pretest assessed how they typed using either a conventional keyboard on a desk or on an articulating keyboard tray , and with or without wrist rests . Workers were r and omly allocated to a control ( n = 15 ) or test group ( n = 23 ) that used their existing keyboard in a DT system . A post-test was conducted 3 weeks later . Results showed no significant changes in wrist posture , seated posture or reports of musculoskeletal discomfort for the control group , and approximately 50 % of typing wrist movements put the h and in a neutral zone . There were significant improvements in wrist posture , seated posture and upper body musculoskeletal discomfort for the test group using the DT system . Over 80 % of typing wrist movements put the h and into a neutral zone with the DT arrangement . Reactions to using a conventional keyboard on a DT system were positive
