Study objectivesA lifestyle physical activity intervention has an added value in addition to a work style intervention focused on ergonomics, breaks and coping with high work demands on the recovery from neck and upper limb symptoms in computer workers.
Ethics approval(s)The study was approved by the medical ethics committee of the VU University Medical Center (07/09/2004), protocol number 2004/027.
Health condition(s) or problem(s) studiedNeck and upper limb symptoms
InterventionThe interventions for the two intervention groups both consist of six group meetings in a six month period that take place at the workplace, during work time and under the supervision of a specially trained counsellor. In both intervention groups the goal of the group meetings is to improve workplace ergonomics, the number and quality of breaks and coping behaviour with regard to high work demands. In the work style and physical activity group the additional goal is to increase moderate to heavy physical activity. Both intervention groups are compared with a control group that does not receive any advice.
Intervention typeOther
