The current study compares biomechanical and productivity outcomes
related to the use of a Klockenburg (split and angled) style keyboard as opposed
to the use of a standard PC 101 style keyboard among office workers. The study
used 10 subjects (5 male and 5 female) who were employees of a large
insurance company. Subjects were categorized by job classification, including 5
exempt and 5 nonexempt employees. Each subject was evaluated on both of the
keyboards in a laboratory setting after three weeks of familiarization with the
keyboards at their workstation. Productivity was measured as words per minute.
In the lab, biomechanical outcomes included angular measures of forearm
pronation/supination, wrist flexion/extension, wrist radial/ulnar deviation and neck
angle. Lab results showed that the Klockenburg keyboard negatively impacted
productivity and neck posture, while forearm pronation/supination and wrist
radial/ulnar deviation were in more neutral positions. There was no significant
difference in wrist extension between the two keyboards. In the field, the
Klockenburg keyboard did not impact productivity.
