- What it is
- A laboratory study of 11 experienced keyboard operators who typed on a split keyboard set up in a conventional way and in three split configurations, measuring ulnar deviation of the wrists.
- How much weight it carries
- Peer-reviewed, from a university mechanical engineering group. Measures wrist angle during typing, not symptoms or injury, and the group was small.
Facts taken from this source
- The 2001 split keyboard study tested 11 experienced computer keyboard operators.
“Eleven experienced computer keyboard operators participated in this study” (Methods)
- In the 2001 study, the three split keyboard configurations produced no differences in ulnar deviation from each other.
“There were no differences in ulnar deviations among the 3 alternative configurations.” (Results)
- In the 2001 study, all three split keyboard configurations reduced ulnar deviation of both wrists compared with a conventional keyboard setup.
“The 3 alternative configurations resulted in ulnar deviation of both wrists that were less than ulnar deviation from typing on a conventional setup.” (Results)
