The effect of an alternative keyboard on musculoskeletal discomfort: A randomized cross-over trial

There is limited research on the effectiveness of alternative keyboards in reducing discomfort in the workplace. We hypothesized that participants using a fixed split-angle (alternative) keyboard would report significantly greater improvements in discomfort in comparison to those using a standard keyboard. Additionally, we hypothesized that at 5 months participants would significantly prefer the configuration of the alternative keyboard in comparison to the standard keyboard.
