Abstract
Thirty Canadian police officers, divided into six groups, participated in the redesign of the interior of the patrol car. Three of the group consisted of individuals having a history of low back disease. The effects of participating in a design proces on the characteristics of the final design and in the perception of the low back pain was studied in a semi-experimental setting. The participants developed a strong committment to the participatory design process, which was reflected in their productions. The differences between participants with and without a history of a low back disease was not marked. The former tended to stress posture-related elements in their analysis and design. (A)
